The European Commission is introducing new regulations on submission and publication of data in electricity markets (SPDEM) and on wholesale energy market integrity and transparency (REMIT). I discuss issues relevant for undertaking an evaluation of such regulations. I argue that, for market performance, more information is not always better; indeed, more information may undermine market…
Electricity Scarcity Pricing Through Operating Reserves
Suppressed prices in real-time markets provide inadequate incentives for both generation investment and active participation by demand bidding. An operating reserve demand curve developed from first principles would improve reliability, support adequate scarcity pricing, and be straightforward to implement within the framework of economic dispatch. This approach would be fully compatible with other market-oriented policies….
Capacity Markets in PJM
The PJM capacity market evolved from a mechanism to support fair and efficient retail competition, to a core market design component implemented to provide adequate revenue to attract sufficient supply and demand side resources to meet PJM’s administrative reliability criteria. The lessons learned in the evolution of the PJM capacity market illustrate issues that are…
Capacity Market Fundamentals
Electricity capacity markets work in tandem with electricity energy markets to ensure that investors build adequate capacity in line with consumer preferences for reliability. The need for a capacity market stems from several market failures. One particularly notorious problem of electricity markets is low demand flexibility. Most customers are unaware of the real time prices…
Capacity Markets – Lessons Learned from the First Decade
Capacity markets were introduced in the U.S. in the late 1990s as a means to ensure “resource adequacy” in liberalized electricity markets where generation must be built by merchant investors rather than regulated entities. This paper provides a general introduction to these markets: why they exist, how they function, how well they have performed in…

Climate Policy with the Chequebook – An Economic Analysis of Climate Investment Support
Across the globe, climate policy is increasingly using investment support instruments, such as grants, concessional loans, and guarantees – whereas carbon prices are losing importance. This development substantially increases the risk of inefficient public spending. In this paper, we examine the ability of finance instruments to effectively and efficiently address market failures related to clean…

The Impact of Behavioral Science Experiments on Energy Policy
One of the most exciting areas of research today is the use of experiments informed by behavioral science to understand how to change energy consumption decisions of consumers. This article provides a survey and synthesis of experiments and focuses on general principles that can be gleaned from these experiments to date. We identify four general…
