Book Description
Problem Definition: Combined heat and power (CHP) plants generate electricity and useful heat at the same time, reaching high efficiencies. There are many benefits to utilities of having CHP plants in their portfolio, including increasing power reliability, reducing transmission losses, and meeting environmental regulations. Despite these benefits, only 3% of all CHP capacity in the U.S. is utility owned. We study the economics of utility ownership of CHP plants and examine the impact of regulatory policies on such investments.Academic/Practical Relevance: There is little research on the economics of utility ownership of CHP. Given the low CHP adoption rate in the U.S., particularly by utilities, it is of general interest to understand the economics of CHP and how policies affect CHP adoption.Methodology: We solve for the optimal form of investment and dispatch decisions using analytic economic modeling. Following this, we present a numerical study calibrated with real data from three different utilities in the U.S., including their existing generation portfolio, uncertainties in demand and fuel prices, granular renewable intermittency, and grid reliability.Results: A utility's investment in different generating technologies follows an Invest/Stay Put/Disinvest (ISD) policy for a given siting decision of CHP plants. Numerically, we find investment in many CHP plants to be attractive to utilities, even without regulatory policy intervention. A low to moderate emissions tax makes CHP even more attractive for utilities.Managerial Implications: There is significant interest in energy sustainability in the industrial and academic communities. We shed light on a technology that is well known to practitioners but less explored in academia and demonstrate its benefits rigorously. We show that utilities should seriously consider adopting CHP in their generation portfolios, and our model framework can aid such decisions.

Book Description
Small and micro combined heat and power (CHP) systems are a form of cogeneration technology suitable for domestic and community buildings, commercial establishments and industrial facilities, as well as local heat networks. One of the benefits of using cogeneration plant is a vastly improved energy efficiency: in some cases achieving up to 80–90% systems efficiency, whereas small-scale electricity production is typically at well below 40% efficiency, using the same amount of fuel. This higher efficiency affords users greater energy security and increased long-term sustainability of energy resources, while lower overall emissions levels also contribute to an improved environmental performance. Small and micro combined heat and power (CHP) systems provides a systematic and comprehensive review of the technological and practical developments of small and micro CHP systems. Part one opens with reviews of small and micro CHP systems and their techno-economic and performance assessment, as well as their integration into distributed energy systems and their increasing utilisation of biomass fuels. Part two focuses on the development of different types of CHP technology, including internal combustion and reciprocating engines, gas turbines and microturbines, Stirling engines, organic Rankine cycle process and fuel cell systems. Heat-activated cooling (i.e. trigeneration) technologies and energy storage systems, of importance to the regional/seasonal viability of this technology round out this section. Finally, part three covers the range of applications of small and micro CHP systems, from residential buildings and district heating, to commercial buildings and industrial applications, as well as reviewing the market deployment of this important technology. With its distinguished editor and international team of expert contributors, Small and micro combined heat and power (CHP) systems is an essential reference work for anyone involved or interested in the design, development, installation and optimisation of small and micro CHP systems. Reviews small- and micro-CHP systems and their techno-economic and performance assessment Explores integration into distributed energy systems and their increasing utilisation of biomass fuels Focuses on the development of different types of CHP technology, including internal combustion and reciprocating engines

Book Description
This book makes intelligible the wide range of electricity generating technologies available today, as well as some closely allied technologies such as energy storage. The book opens by setting the many power generation technologies in the context of global energy consumption, the development of the electricity generation industry and the economics involved in this sector. A series of chapters are each devoted to assessing the environmental and economic impact of a single technology, including conventional technologies, nuclear and renewable (such as solar, wind and hydropower). The technologies are presented in an easily digestible form.Different power generation technologies have different greenhouse gas emissions and the link between greenhouse gases and global warming is a highly topical environmental and political issue. With developed nations worldwide looking to reduce their emissions of carbon dioxide, it is becoming increasingly important to explore the effectiveness of a mix of energy generation technologies.Power Generation Technologies gives a clear, unbiased review and comparison of the different types of power generation technologies available. In the light of the Kyoto protocol and OSPAR updates, Power Generation Technologies will provide an invaluable reference text for power generation planners, facility managers, consultants, policy makers and economists, as well as students and lecturers of related Engineering courses. · Provides a unique comparison of a wide range of power generation technologies - conventional, nuclear and renewable· Describes the workings and environmental impact of each technology· Evaluates the economic viability of each different power generation system

Book Description
Americans' safety, productivity, comfort, and convenience depend on the reliable supply of electric power. The electric power system is a complex "cyber-physical" system composed of a network of millions of components spread out across the continent. These components are owned, operated, and regulated by thousands of different entities. Power system operators work hard to assure safe and reliable service, but large outages occasionally happen. Given the nature of the system, there is simply no way that outages can be completely avoided, no matter how much time and money is devoted to such an effort. The system's reliability and resilience can be improved but never made perfect. Thus, system owners, operators, and regulators must prioritize their investments based on potential benefits. Enhancing the Resilience of the Nation's Electricity System focuses on identifying, developing, and implementing strategies to increase the power system's resilience in the face of events that can cause large-area, long-duration outages: blackouts that extend over multiple service areas and last several days or longer. Resilience is not just about lessening the likelihood that these outages will occur. It is also about limiting the scope and impact of outages when they do occur, restoring power rapidly afterwards, and learning from these experiences to better deal with events in the future.
