Ancillary Market Saturation in CAISO and ERCOT: A Series of Predictable Events
July 27, 2023
Ancillary services have been a key component of storage revenue stacks since batteries began coming online, turbocharging returns for some operating projects. However, this turbocharger has already started to wane in CAISO and ERCOT and services as a harbinger for ancillary decline in other markets.
Resource Adequacy Modeling for a High Renewable Future
June 9, 2022
Planning for power system resource adequacy, once a relatively straightforward engineering calculation, is now characterized by growing complexity and uncertainty in both supply and demand. In the face of increasing complexity, many of the tools power system planners relied on are now becoming obsolete. This paper defines approaches for determining resource adequacy in high renewable systems with energy storage.
Making the Right Resource Choice Requires Making the Right Model Choice
September 1, 2021
What do traditional production cost models miss about a changing resource mix with more intermittent renewables and storage? A lot! This paper shows how traditional models lead to model limited choice, where model limitations lead to systematic biases in favor of relatively inflexible legacy resource options.
