Abstract:
The present report deals with economic issues of selecting means ensuring the capacity adequacy of electric power systems. Cost analysis of various engineering measures ensuring the capacity adequacy has been performed, namely: construction of backup generating facilities, erection of new power transmission lines, or increase of transmission capacity of existing power lines. The cost-based analysis has been conducted based on investment programs and regulatory acts in place. Recommendations on developing computational models of power systems have been given based on the results obtained in order to assess the capacity adequacy parameters, with account made for the cost of various engineering measures to be taken for their improvement.In prevailing practice of calculation of capacity adequacy parameters, the structure of electric power systems transmission network is presented as a transport model which makes an aggregate of reliability zones and tie-lines between them of a given transmission capacity. The main objective of calculation of capacity adequacy parameters is to determine the required generating capacity redundancy level, i.e. the values of the capacity margin and its location within electric power systems to ensure a required level of capacity adequacy. With that in mind, when evaluating and accordingly when forming transport models, it should be useful to take into account the transmission constraints only for those power grid segments, whose cost of transmission capacity increase is comparable with that of construction of new generating facilities.On the basis of calculation data, one may state that for overhead electric lines of short or average length the cost of 1 kW of its transmission capacity will be considerably lower than that of installed capacity of a new generating facility, with the above costs comparable only with the length of the line close to its critical value. When forming transport models of electric power systems, it is useful to take into account not only the distance between electric power system nodes, but also their potential need of margin capacity. As far as remote nodes are concerned, if these are of low need in margin capacity, it should be reasonable to separate them as specifi c reliability areas.

Abstract:
Increasing economic importance of the Arctic, further intensification of northern sea routes, and exceptional sensitivity of the arctic natural environment to anthropogenic impacts are fundamental factors for a comprehensive study of environmental aspects in the application of innovative technologies for the development of infrastructure in the Arctic. Despite the growing interest in low-power nuclear power plants as a distributed generation facility, their possible application in technologically isolated power systems does not lose relevance. The development of both the Arctic and Far Eastern regions of the Russian Federation presents great opportunities and demand for the use of nuclear power sources. Also, development programs for the Russian arctic zone imply a significant increase in the role and number of nuclear power facilities, in other words of potential radiation-hazardous facilities. Large-scale use of nuclear-powered installations in the Arctic necessitates advanced development of a scientifically grounded and modern forecasting system as well as assessments of threats and risks in case of possible radiation emergencies at nuclear- and radiation-hazardous facilities. Also, the development of proposals for necessary measures to minimize negative consequences of such emergencies is required. This is especially true for the case of compact placement of industrial, infrastructure and residential facilities in the Arctic in the immediate vicinity of nuclear facilities. The paper demonstrates that the demand for low-power nuclear power plants and their competitiveness will grow steadily in the conditions of electric-power industry decentralization, further spread of distributed generation and the development of technologically isolated power systems. Approaches to the generation of a low nuclear-power system based on the philosophy of industrialization of production and centralized management are presented. Special features of the environmental impact assessment of low-power nuclear power plants for the development of a methodology to study the radio-ecological hazard related problems are provided.

Abstract:
A deterministic quantitative model has been developed to compare the technical, economical and environmental feature of various electric power generating plants. The model, which is based on matrix operations, is used in evaluating the various aspects of energy sources available for electricity generation systems in a developing country. Several energy sources which could be considered for production of electricity to meet current and future electricity demands have been chosen. These will include fossil fuel fired, nuclear, and natural-renewable energy power plants. And, a set of criteria for optimized selection includes five area of concerns: energy economy, energy security, environmental protection, socio-economic development and technological aspects for the electric power generations. The model developed in this study is applied to the Indonesian’s electric power sector development. Most of the data required are obtained from various sources related to power industry in Indonesia, such as the electricity generating authority of Indonesia (Perusahaan Listrik Negara, PLN), Government of Indonesia, World Bank, Asian Development Bank, United Nations, and other sources, both in published and public domains. The result of this study will be a ranking of energy sources for Indonesia power generation systems based on the Euclidean composite distance of each alternative to the designated optimal source of energy.

Abstract:
Hybrid microgrids are presented as a solution to many electrical energetic problems. These microgrids contain some renewable energy sources such as photovoltaic (PV), wind and biomass, or a hybrid of these sources, in addition to storage systems. Using these microgrids in electric power generation has many advantages such as clean energy, stability in supplying power, reduced grid congestion and a new investment field. Despite all these microgrids advantages, they are not widely used due to some economic aspects. These aspects are represented in the net present cost (NPC) and the levelized cost of energy (LCOE). To handle these economic aspects, the proper microgrids configuration according to the quantity, quality and availability of the sustainable source of energy in installing the microgrid as well as the optimal design of the microgrid components should be investigated. The objective of this paper is to design an economic microgrid system for the Yanbu region of Saudi Arabia. This design aims to select the best microgrid configuration while minimizing both NPC and LCOE considering some technical conditions, including loss of power supply probability and availability index. The optimization algorithm used is Giza Pyramids Construction (GPC). To prove the GPC algorithm’s effectiveness in solving the studied optimization problem, artificial electric field and grey wolf optimizer algorithms are used for comparison purposes. The obtained results demonstrate that the best configuration for the selected area is a PV/biomass hybrid microgrid with a minimum NPC and LCOE of $319,219 and $0.208/kWh, respectively.

Abstract:
Battery Electric vehicle (BEV) has been set as one of the most prominent sectors of automobile industry in China in the future due to its significant contribution to energy safety, low carbon emission and leading technology status in vehicle driven by new energy. High penetration of BEV will have obvious impacts on power systems, and its load characteristics are quite different from those traditional loads. Therefore with an eye on the safe, stable and economic operation of power system, this paper studied the impacts of EV on power systems from four aspects: total electricity demand, power rush in short period, power quality and vehicle to grid (V2G) technology. Total electricity demand by BEV charging in 2020 in China was firstly estimated in the paper, and it is sure that power system has the capability to meet this demand. However uncontrolled massive BEV charging will probably results in higher peak load and upgrading requirement of power systems, so orderly charging is required. EV battery is charged through rectifier, which will decrease power quality by harmonic current, therefore power electronic equipment is required to ensure power quality. Finally possibility of scheme of vehicle to grid (V2G) application is discussed when the scale of BEV is large enough and performance of EV battery is greatly improved.

Abstract:
One of the most challenging aspects of a new district heating (DH) design is its general performance, which will determine the ecological and economic impacts of the investment. Choosing the lowest applicable temperatures which are distributed via ultra-low-temperature district heating (ULTDH) systems may yield the desired results. The article elaborates the economic and ecological aspects of the application of ULTDH. The results of the analysis indicate that the capacity factor may be significantly improved, while the overall ecological effects of the investment are strongly dependent on the previously used heat source and the source of electric power.

Abstract:
The purpose of the article is to consider the problems of investment stimulation of economic growth in Russia during the implementation of the digitalization project for the management of electric and heat power assets using intelligent cyberphysical systems. The subject of the study isthe organizational and informational aspects of improving the management of the electric and heat energy sectors in the Russian energy sector. The necessity of “pushing” the Russian economy out of the crisis cycle due to investment stimulation of economic growth is substantiated. The electric and heat energy sector in the Russian energy sector has been proposed as a sectoral driver of eco-nomic growth and investment applications, since it is in this sector that competitive conditions for most Russian businesses are formed, which are energy-dependent and often energy-intensive. The main directions of digital restructuring of the entire system for managing electric and heat power assets are formulated. The basic principles of risk-based management based on intelligent cyber-physical systems are developed. The result is an automated control of each ruble along the chain of technological operations during operation and maintenance, which will ensure the receipt of investments from internal sources for the purpose of modernization.The article is aimed at managers and specialists of government and corporate management bod-ies, and may also be useful for researchers, postgraduates and students.

Abstract:
Conventional diesel engines are considered by some to be contributors to environmental problems since they emit NOx, a suspected acid rain precursor. Initial testing has shown that CWS-fueled diesels emit substantially reduced NOx emissions. While emissions of particulates and SOx may be potentially higher with coal fuels, assessment of the control technology indicates excellent potential for meeting existing and future standards for these emissions. As a result of activities managed by the Morgantown Energy Technology Center, the economic and technical feasibility of CWS-fueled diesel engines has been determined. Recently, both General Electric and A. D. Little/Cooper Bessemer were selected for 5-year contracts aimed at developing by 1993 the components and subsystems necessary for subsequent private sector demonstration and commercialization of coal-fueled diesel power systems. The development of these CWS-fueled systems will necessitate the application of hot gas cleanup contaminant control technology to ensure that the systems burn coal in an environmentally sound manner. The objective of this paper is to discuss the environmental concerns, emission goals, and the control methodologies, devices, and strategies that will be used to ensure CWS-fueled diesel engines will meet current and potential environmental standards.

Abstract:
Wholesale electricity markets now operate in many countries around the world. These markets determine a spot price for electricity as the clearing price when generators bid in energy at various prices. As the trading in a wholesale electricity market can be seen as a dynamic repeated game, it would be expected that profit maximising generators learn to engage in tacit collusion to profitably increase spot market prices. This thesis investigates this tacit collusion of generators in oligopolistic electricity markets. We do not follow the approach of previous work in game theory that presupposes firms' collusive strategies to enforce collusion in an oligopoly. Instead, we develop a co-evolutionary approach (extending previous work in this area) using a genetic algorithm (GA) to co-evolve strategies for all generators in some stylised models of an electricity market. The bidding strategy of each generator is modelled as a set of bidding actions, one for each possible discrete state of the state space observed by the generator. The market trading interactions are simulated to determine the fitness of a particular strategy. The tacitly collusive outcomes and strategies emerging from computational experiments are thus obtained from the learning or evolutionary process instead of from any pre-specification. Analysing many of those emergent collusive outcomes and strategies. we are able to specify the mechanism of tacit collusion and investigate how the market environment can affect it. We find that the learned collusive strategies are similar to the forgiving trigger strategies of classical supergame theory (Green and Porter, 1984). Also using computational experiments, we can determine which characteristics of the market environment encourage or hinder tacit collusion. The findings from this thesis provide insights on tacit collusion in an oligopoly and policy implications from a learning perspective. With modelling flexibility, our co-evolutionary approach can be extended to study strategic behaviour in an oligopoly considering many other market characteristics.

Nesta tese, os Sistemas Imunológicos Artificiais são aplicados a diferentes instâncias do despacho econômico e econômico/ambiental de energia elétrica. Os sistemas imunes considerados são baseados no princípio da seleção clonal e usam uma representação real com operador de \emph{aging} puro e operadores de hipermutação utilizando distribuições de probabilidade Gaussianas e de Cauchy. Algoritmos Culturais utilizando fontes de conhecimento normativo, situacional, histórico e topográfico são incorporados para melhorar a capacidade de otimização global dos sistemas imunes. Todas as abordagens propostas possuem vários pontos de auto-adaptação e a maioria utiliza um operador de busca local baseado na técnica quase-simplex. Uma sequência caótica também é considerada como uma potencial fonte de melhoria na variação cultural do algoritmo. Procedimentos de reparação constituem outra contribuição do trabalho e são aplicados para evitar lidar com soluções infactíveis em todos os problemas abordados. Na primeira parte dos experimentos, quatro instâncias do problema do despacho econômico de energia são consideradas. Em todos os casos, foi utilizada uma função não suave de custo de combustível levando em consideração os efeitos de ponto de válvula. Uma das instâncias também considera as perdas na transmissão de energia. Nos experimentos de comparação entre as abordagens propostas, as versões imuno-culturais superam a versão puramente imune. O método cultural proposto que apresenta melhor resultado é escolhido para ser comparado a outras técnicas modernas de otimização reportadas na literatura recente. Em todos os casos mono-objetivo considerados, a abordagem proposta é capaz de encontrar o menor custo de combustível. A segunda parte dos experimentos trata do problema do despacho econômico/ambiental. Esta é uma versão do problema do despacho econômico de energia onde a emissão de poluentes é adicionada como um novo objetivo, tornando este um problema de otimização multiobjetivo não-linear com restrições. Algoritmos imuno-culturais baseados em fatores de escalarização e dominância de Pareto são propostos para este caso. Várias instâncias do problema são utilizadas nos experimentos, algumas das quais consideram perdas na transmissão de energia. Os algoritmos propostos são favoravelmente comparados com um algoritmo do estado-da-arte para otimização multiobjetivo. O melhor algoritmo proposto também é comparado com métodos reportados na literatura recente. As comparações mostram o bom desempenho da melhor abordagem proposta e confirmam seu potencial para resolver o problema do despacho econômico/ambiental de energia.
In this thesis, Artificial Immune Systems are applied to solve different instances of the economic and environmental/economic load dispatch problems. The immune systems considered here are based on the clonal selection principle and use a real coded representation with pure aging operator and hypermutation operators utilizing Gaussian and Cauchy distributions. Cultural Algorithms using normative, situational, historical and topographical knowledge sources are incorporated to improve the global optimization capability of immune systems. All the proposed approaches have several points of self-adaptation and most of them use a local search operator that is based on a quasi-simplex technique. A chaotic sequence is also considered as a potential source of improvement to the cultural variation. Repair procedures represent another contribution of this work and are applied to avoid dealing with infeasible solutions in all the considered problems. In the first part of the experiments, four instances of the economic load dispatch problem are considered. In all the cases, a non-smooth fuel cost function which takes into account the valve-point loading effects is utilized. One of instances also considers energy transmission losses. In the experiments conducted to compare the proposed approaches, the immune-cultural based approaches outperformed the pure immune version. The proposed cultural method which presents the best performance is chosen to be compared with other modern optimization techniques reported in the recent literature. In all the mono-objective cases considered, the proposed approach is capable of finding the minimum fuel cost value. The second part of the experiments deals with the environmental/economic load dispatch problem. This is a multi-objective version of the economic load dispatch where pollution emission is added as an objective, it is formulated as a non-linear constrained multi-objective optimization problem. Cultural immune algorithms based on scalarizing factors and Pareto-dominance are proposed for this case. Several instances of the problem are considered, some dealing with energy transmission losses. The proposed algorithms are favorably compared with a state-of-art algorithm for multi-objective optimization (the Non-dominated Sorting Genetic Algorithm II - NSGA - II). The best proposed algorithm is also compared with methods reported in recent literature. The comparisons demonstrate the good performance of the best proposed approach and confirm its potential to solve the environmental/economic load dispatch problem.

Abstract:
The thesis explores the potential of Genetic Algorithms (GAs) for optimising the operation of electric power systems. It discusses methods which have resulted in significant direct cost saving in operating an electric power system. In particular, the thesis demonstrates the simple search procedure and the powerful search ability of Gas in multi-modal, multi-objective problems, which are resisted by the most well known conventional techniques. Special emphasis has been given to the effectiveness of the enhanced genetic based algorithms and the importance of sophisticated problem structures. Finally, the feasibility and suitability of genetic based algorithms for power system optimisations are verified on a real power supply system. The basic requirement in operating a power system is to ensure that the whole system is run at the minimum possible cost, and the lowest possible pollution level, while reliability and security are maintained. These requirements have resulted in a wide range of power system optimisation problems. In this work, a selection of problems concerning operation economy, security and environmental impact have been dealt with by Genetic Algorithms. These problems are in order of increasing complexity as the project progresses: they range from static problems to dynamic problems, single objective to multi-objectives, softly constrained problems to harshly constrained problems, simple problem structure to more rigorous problem structure. Despite the diversity, GAs consistently produce solutions comparable to conventional techniques over the wide range of problem spectrum. It has been clearly demonstrated that a sophisticated problem structure can bring significant financial benefits in system operation, it has however added further complexity to the problem, where the best result may only be sought from the genetic based algorithms. The enhancements of Genetic Algorithms have been investigated with the aim of further improving the quality and speed of the solution. They have been enhanced in two levels: the first is to develop advanced genetic strategies, and this is subsequently refined by choosing optimal parameter values to further improve the strategies. The outcome of the study clearly indicates that genetic based algorithms are very attractive techniques for solving the ever more complicated optimisations of electric power systems.

Abstract:
This paper introduces a heat pump system with a latent heat storage utilizing seawater installed in an aquarium. Heat from the seawater is collected and used as the heat source for the heat pump system. This maintains the indoor conditions at constant temperature and relative humidity. With regard to the heat pump system using low-temperature unutilized heat source, development is introduced on a heat source load responsive heat pump system, with combines a load variation responsive heat pump utilizing seawater with a latent heat (ice plus water slurry) storage system using nighttime electric power serving for electric power load leveling. The desired outcome would be to show that the costs of generating heat energy with the seawater-source heat pump are significantly less than those with the air-source heat pump and the oil-fired system. Additionally, the CO2 emissions for the seawater-source heat pump compare favourably as they maybe less than those for the other conventional assumed systems described.

Abstract:
A deterministic quantitative model has been developed for use to compare the technical, economical and environment feature of various electric power generating plants. The model, which is based on matrix operations, is used in evaluating the various aspects of energy sources available for the electricity generation systems in a developing country. Several energy sources are chosen which could be considered for production of electricity to meet current and future electricity demands. A complete set of energy sources will include fossil fuel fired power plants, nuclear power plants, and natural-renewable energy power plants. A customized computer code is developed to evaluate the overall function for each system from the performance corresponding to the selected energy attributes includes five area of concerns; energy economy, energy security, environmental protection, socio-economic development and technological aspects for the electric power generations. The model developed in this study is applied to the Indonesian’s electric power sector development. Most of the data required for the model application are obtained from various sources related to power industry in Indonesia, such as the Electricity Generating Authority of Indonesia (Perusahaan Listrik Negara, PLN), Government of Indonesia, World Bank, Asian Development Bank, United Nations, and other sources, both in published and public domains. The optimization technique is kept flexible so that it can accommodate other attributes that will be found to be important according to the decision maker’s preference. By so doing, the model virtually can be used to attack any decision problem with various different attributes to reach an optimal decision concerning the selection of energy sources for electricity generation. The result of this study will be a rank of energy sources for Indonesia power generation systems based on the composite distance of each alternative to the designated optimal source of energy.

Abstract:
Cooling, Heating and Power (CHP) systems are a form of distributed generation that uses internal combustion prime-power engines to generate electricity while recovering heat for other uses. CHP is a promising technology for increasing energy efficiency through the use of distributed electric and thermal energy recovery-delivery systems at or near end-user sites. Although this technology seems to be economically feasible, the evaluation and comparison of CHP systems cannot be restricted to economical considerations only. Standard economic analysis, such as life cycle economic analysis, does not take in consideration all the benefits that can be obtained from this technology. For this reason, several aspects to perform a non-conventional evaluation of CHP systems have to be considered. Among the aspects to be included in a non-conventional evaluation are: power reliability, power quality, environmental quality, energy-efficient buildings, fuel source flexibility, brand and marketing benefits, protection from electric rate hikes, and benefits from promoting energy management practices. Some benefits of these non-economical evaluations can be transferred into an economic evaluation but others give intangible potential to the technology. This paper focus on a non-conventional evaluation based on energy-efficient buildings, which is associated to energy conservation and improvement of the building energy performance rating for government energy programs like Energy Star and Leadership in Energy and Environmental Design (LEED). Results show that the use of CHP systems could improve the Energy Star Rating in more than 50 points. The Energy Star Rating is significant on the LEED Rating as a building can score up to 10 points of the 23 available in the Energy & Atmosphere category on energy efficiency alone. As much as 8 points can be obtained in this category due to the Energy Star rating increment from the use of CHP systems. Clearly the use of CHP systems will help building owners to reach the benefits from these energy programs while improving the overall energy use and energy cost.

Abstract:
This paper investigates energy savings and economic aspects related to the use of microturbine generators in commercial buildings either for cogeneration (electricity+heat) or for trigeneration (electricity, heat and cold). In all calculations, reference is made to a 25 kWel–class commercial micro-turbine generator (MTG), tested by the authors. Various plant schemes are considered, based on one or several MTG sets. The possibility of generating heat and/or cold also by an electrically driven inverse-cycle air-to-water heat pump/chiller system is also considered. Calculations are based on the simulation code TRIGEN developed by the authors. The code provides detailed energy, economic and emission yearly balances. The plant operating mode is optimized in each time interval. The results indicate that, due to large load variations, (i) the optimum turbine nominal output is in the range of about 70% of the electric peak demand, (ii) energy savings are marginal, (iii) advantages related to splitting the overall capacity on more than one unit are marginal and (iv) the addition of an absorption machine improves the plant economics.

Abstract:
The utilization of vegetable oils, and in particular the palm oil, as fuel in the power generation has had a remarkable development in the last few years. Generally the vegetable oil can be used with a particular marine-derived diesel ICE, with low rpm and an electric conversion efficiency of about 40%. The efficiency is strictly connected to the size of the plant. Moreover, the considerable amount of the required vegetable oil to feed the system forces to import the fuel. This is one of the most critical elements as the palm oil is subject to continuous and wide variations in prices. Due to this variation it is difficult to obtain a stable and convenient fuel supply over a long period of time. The present work is aimed at evaluating and estimating the economic, technical and environmental feasibility of a 20 MW plant for the stationary power generation fed with palm oil, enlightening the system solution (technical constructive aspects) and the economic appraisal, on the basis of variations in oil prices. Finally, the economic sensibility analysis based on the fuel cost and the European mechanisms of biomass incentives.

Abstract:
Abstract Polygeneration improves energy efficiency and reduces both energy consumption and pollutant emissions compared to conventional generation technologies. A polygeneration system is a variation of a cogeneration system, in which more than two outputs, i.e., heat, power, cooling, water, energy or fuels, are accounted for. In particular, polygeneration systems integrating solar energy and water desalination represent promising technologies for energy production and water supply. They are therefore interesting options for coastal regions with a high solar potential, such as those located in southern Peru and northern Chile. Notice that most of the Peruvian and Chilean mining industry operations intensive in electricity and water consumption are located in these particular regions. Accordingly, this work focus on the design and integration of a polygeneration system producing industrial heating, cooling, electrical power and water for an industrial plant. In particular, the design procedure followed in this work involves integer linear programming modeling (MILP). The technical and economic feasibility of integrating renewable energy technologies, thermal energy storage, power and thermal exchange, absorption chillers, cogeneration heat engines and desalination technologies is particularly assessed. The polygeneration system integration carried out seeks to minimize the system total annual cost subject to CO2 emissions restrictions. Particular economic aspects accounted for include investment, maintenance and operating costs.

Abstract:
Two aspects of the development trend of current nuclear fission technology are discussed. The first aspect is to improve economic competitiveness and safety for searching opportunity of enlarging the share of nuclear power. The second aspect is to explore new ways of improving the efficiency of nuclear fuel utilization and of reducing the geological repository volume of radioactive products from nuclear power generation. Sustainable development of Chinese economy in 21st century will mainly rely on sustainable supply of clean energy with indigenous natural resources. The burden of current coal-dominant energy mix and the environmental pollution due to energy consumptions has led nuclear power to be an indispensable choice for further expanding electricity generation capacity and for reducing greenhouse effect gases emission in China. The long-term sustainable development strategy with nuclear fission technology beyond generation-IV for electric power generation, namely the fusion-fission hybrid subcritical reactor technology, is discussed. The impact of the proposed fission-fusion hybrid reactor to future nuclear power generation technology will reply on the success of the ITER-scale (500MW fusion power) Tokamak to burn plasma continuously in the predictable future. The main challenges and prospects of the strategy are also analyzed. The preliminary analysis has shown that the fission in the subcritical blanket driven by fusion neutrons can effectively amplify the energy carried by fusion neutron and maintain breeding of fissile material and tritium. It has been found from the results of a conceptual design that this new type of fusion-fission hybrid reactor may meet the requirement of China’s long-term sustainable development of nuclear energy.

Abstract:
In the late 1970’s, due to increasing electric energy costs and the potential for power interruption at Solar Turbines Incorporated’s Harbor Drive manufacturing facility, management evaluated several self-generating options available at the time. With large fluctuating loads and a very limited need for thermal energy, the appropriate solution was determined to be peak shaving. In 1980, a 2.5-MW dual fuel industrial gas turbine generator set was installed. Its intended operating cycle was during on-peak billing periods, 5 days a week throughout the year. Through August 31, 1993, the system has accumulated 22,743 hours of use and 3879 starts. Its overall start reliability has been 99.9% with an availability of 98.2%. Payback on the installation was in 4.2 years. It has continued to generate savings since installation, with net savings for 1992 alone exceeding $470,000. This paper highlights the key aspects of the economic methodology justifying installation of the peak shaving system, operating procedures, maintenance practices and system modifications put in place over the life of the installation.

Abstract:
The Smart Energy Design Assistance Center assessed the administrative, technical, and economic aspects of feasibility related to the procurement and installation of photovoltaic solar systems on IDOT-owned buildings and lands. To address administrative feasibility, we explored three main ways in which IDOT could procure solar projects: power purchase agreement (PPA), direct purchase, and land lease development. Of the three methods, PPA and direct purchase are most applicable for IDOT. While solar development is not free of obstacles for IDOT, it is administratively feasible, and regulatory hurdles can be adequately met given suitable planning and implementation. To evaluate IDOT assets for solar feasibility, more than 1,000 IDOT sites were screened and narrowed using spatial analytic tools. A stakeholder feedback process was used to select five case study sites that allowed for a range of solar development types, from large utility-scale projects to small rooftop systems. To evaluate financial feasibility, discussions with developers and datapoints from the literature were used to create financial models. A large solar project request by IDOT can be expected to generate considerable attention from developers and potentially attractive PPA pricing that would generate immediate cash flow savings for IDOT. Procurement partnerships with other state agencies will create opportunities for even larger projects with better pricing. However, in the near term, it may be difficult for IDOT to identify small rooftop or other small on-site solar projects that are financially feasible. This project identified two especially promising solar sites so that IDOT can evaluate other solar site development opportunities in the future. This project also developed a web-based decision-support tool so IDOT can identify potential sites and develop preliminary indications of feasibility. We recommend that IDOT begin the process of developing at least one of their large sites to support solar electric power generation.
