Used, But How Useful?
The report argues that rate-regulated utilities use 'self-commitment' to bypass market merit order, running coal plants that are objectively uneconomic and passing the resulting losses to captive customers through state fuel-cost-recovery processes. Using PLEXOS modeling for the MISO region in 2018, the authors find that this practice cost customers $350 million and suppressed regional market clearing prices by 2.4%. The report identifies Cleco and DTE Energy as significant contributors to these distortions and recommends that state regulators disallow the recovery of imprudent, above-market costs to incentivize efficient dispatch.

SPATIAL AND TEMPORAL INTERACTIONS OF WIND AND SOLAR IN THE NEXT GENERATION UTILITY
The paper argues that the variability of renewable energy can be managed through optimized geographic dispersion and the cross-firming of wind and solar resources. By analyzing data from the MRO, SPP, and ERCOT regions, the study demonstrates that expanding the geographic scope of a renewable portfolio significantly reduces system variability and the frequency of zero-power production. It also finds that combining solar and wind resources further lowers variability compared to wind-only portfolios. The authors conclude that these strategies, combined with demand response, energy storage (such as xEVs), and smart grid communications, can reduce the reliance on conventional baseload power.
