Electricity system operations are often affected by energy policies, but spatial differences in policy impacts are difficult to model. We develop a method for estimating zonal supply curves in transmission-constrained electricity markets that can be implemented quickly by policy analysts with...

On December 19, 2019, the Federal Energy Regulatory Commission (FERC) issued an order dramatically expanding the Minimum Offer Price Rule in PJM’s capacity market. The order changes how electricity-generating resources that receive state subsidies are treated in federally regulated wholesale...

We examine the impact on inter-regional trade in eastern U.S. electricity markets arising from the FERC-supported creation of Independent System Operators (ISOs). Our analysis focuses on the PJM ISO (Pennsylvania, New Jersey, Maryland, and other states) and its trade with the New York ISO and...

Transmission economics remains a difficult area. Market forces alone are generally felt to be insufficient for signaling investment due to appropriability problems and the challenges of “parallel (loop) flow.” Further, there is no generally recognized method of estimating the value of...

Initially created as afterthoughts to competitive electricity markets, capacity markets were intended to enhance system reliability. They have evolved into massive, highly controversial, and poorly understood billion-dollar institutions. Electricity Capacity Markets examines the rationales for...
