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...

The U.S. regulation of high-voltage transmission is highly complex and, as a result, generally poorly understood. The complexity is created by separate, but overlapping, jurisdictional authorities of the U.S. federal regulators and those of individual states, districts, and territories. While...

Currently, most U.S. electricity consumers pay a constant price per kWh consumed that accounts for most of their bill. Ongoing developments in the power system increase efficiency gains that can be made from exposing consumers to widely varying wholesale spot prices. Pure spot pricing is not...
