Book Description
A common approach to regulating electricity is through auction-based competitive wholesale markets. The goal of this approach is to provide a reliable supply of power at the lowest reasonable cost to the consumer. This necessitates market structures and operating rules that ensure revenue sufficiency for all generators needed for resource adequacy purposes. Wholesale electricity markets employ marginal-cost pricing to provide cost-effective dispatch such that resources are compensated for their operational costs. However, marginal-cost pricing alone cannot guarantee cost recovery outside of perfect competition, and electricity markets have at least six attributes that preclude them from functioning as perfectly competitive markets. These attributes include market power, externalities, public good attributes, lack of storage, wholesale price caps, and ineffective demand curve. Until (and unless) these failures are ameliorated, some form of corrective action(s) will be necessary to improve market efficiency so that prices can correctly reflect the needed level of system reliability. Many of these options necessarily involve some form of administrative or out-of-market actions, such as scarcity pricing, capacity payments, bilateral or other out-of-market contracts, or some hybrid combination. A key focus with these options is to create a connection between the electricity market and long-term reliability/loss-of-load expectation targets, which are inherently disconnected in the native markets because of the aforementioned market failures. The addition of variable generation resources can exacerbate revenue sufficiency and resource adequacy concerns caused by these underlying market failures. Because variable generation resources have near-zero marginal costs, they effectively suppress energy prices and reduce the capacity factors of conventional generators through the merit-order effect in the simplest case of a convex market; non-convexities can also suppress prices.

Book Description
Packed with case studies and practical real-world examples, Electricity Marginal Cost Pricing Principles allows regulators, engineers and energy economists to choose the pricing model that best fits their individual market. Written by an author with 13 years of practical experience, the book begins with a clear and rigorous explanation of the theory of efficient pricing and how it impacts investor-owned, publicly-owned, and cooperatively-owned utilities using tried and true methods such as multiple-output, functional form, and multiproduct cost models. The author then moves on to include self-contained chapters on applying estimating cost models, including a cubic cost specification and policy implications while supplying actual data and examples to allow regulators, energy economists, and engineers to get a feel for the methods with which efficient prices are derived in today’s challenging electricity market. A guide to cost issues surrounding the generation, transmission, and distribution of electricity Clearly explains cost models which can yield the marginal cost of supplying electricity to end-users Real-world examples that are practical, meaningful, and easy to understand Explans the policy implications of each example Provide suggestions to aid in the formation of the optimal market price

Book Description
"This thesis investigates the behaviour of electricity markets under marginal and pay-as-bid pricing. Marginal pricing is believed to yield the maximum social welfare and is currently implemented by most electricity markets. However, in view of recent electricity market failures, pay-as-bid has been extensively discussed as a possible alternative to marginal pricing. In this research, marginal and pay-as-bid pricing have been analyzed in electricity markets with both perfect and imperfect competition. The perfect competition case is studied under both exact and uncertain system marginal cost prediction. The comparison of the two pricing methods is conducted through two steps: (i) identify the best offer strategy of the generating companies (gencos); (ii) analyze the market performance under these optimum genco strategies. The analysis results together with numerical simulations show that pay-as-bid and marginal pricing are equivalent in a perfect market with exact system marginal cost prediction. In perfect markets with uncertain demand prediction, the two pricing methods are also equivalent but in an expected value sense. If we compare from the perspective of second order statistics, all market performance measures exhibit much lower values under pay-as-bid than under marginal pricing. The risk of deviating from the mean is therefore much higher under marginal pricing than under pay-as-bid. In an imperfect competition market with exact demand prediction, the research shows that pay-as-bid pricing yields lower consumer payments and lower genco profits. This research provides quantitative evidence that challenges some common claims about pay-as-bid pricing. One is that under pay-as-bid, participants would soon learn how to offer so as to obtain the same or higher profits than what they would have obtained under marginal pricing. This research however shows that, under pay-as-bid, participants can at best earn the same profit or expected profit as under marginal pricing. A second common claim refuted by this research is that pay-as-bid does not provide correct price signals if there is a scarcity of generation resources. We show that pay-as-bid does provide a price signal with such characteristics and furthermore argue that the price signal under marginal pricing with gaming may not necessarily be correct since it would then not reflect a lack of generation capacity but a desire to increase profit."--

Book Description
A major contribution from the economics of regulatory practice in electricity markets is the usefulness of marginal cost pricing. In recent years, however, expanded supply of low cost natural gas, increased energy efficiency, growing market penetration of renewable electricity sources, and substantial reserve margins have contributed to low prices reflecting low marginal costs in wholesale energy and capacity markets. These low prices have placed some existing generation assets at financial risk and disrupted the incentive for new investment. While low prices should indicate ample generation capacity, some observers fear they fail to represent the long run scarcity value of electricity and thereby undermine resource adequacy. This paper explores four paradigms for the future of the electricity sector in a low marginal cost world, including traditional cost of service, energy-only power markets, energy plus capacity remuneration mechanisms, and new relationships between providers and consumers on an energy platform. These paradigms are evaluated for their ability to achieve efficient long-run outcomes in the industry and other criteria.

Book Description
Electricity markets are being deregulated or face new regulatory frameworks. In such changing markets, new pricing strategies will need to consider such factors as cost, value of service and pricing by objective. Pricing in Competitive Electricity Markets introduces a new family of pricing concepts, methodologies, models, tools and databases focused on market-based pricing. This book reviews important theoretical pricing issues as well as practical pricing applications for changing electricity markets.

Book Description
Future electricity systems with tight constraints on carbon emissions will rely much more on wind and solar generation, with zero marginal cost, than today. We use capacity expansion modelling of Texas in 2050 to illustrate wholesale price distributions in future energy-only, carbon-constrained grids without price caps under a range of technology/system assumptions. Tightening carbon emissions constraints dramatically increases the frequency of very low prices. The frequency of high prices also increases, and all resources earn the bulk of their energy market revenues in relatively few hours. The presence of demand response, long-duration energy storage, dispatchable low-carbon generation, or a robust market for hydrogen for non-electricity use (and for energy storage) weakens but does not undo these results. Financial instruments to hedge price volatility will consequently be more costly and it is likely that we will need to redesign capacity remuneration mechanisms to provide adequate incentives for optimal investment in VRE generation and, particularly, storage. In order to encourage economy-wide electrification, the marginal retail price of electricity should be low whenever the wholesale price is low. With automated control of demand via demand response contracts, the risks of price volatility faced by retail customers can be mitigated without sacrificing efficiency. To encourage economy-wide electrification, the marginal retail price of electricity should be low when the wholesale spot price is low. We discuss ways of reducing consumers' risk in this world while providing adequate investment incentives.
