With the new appointments, Biden appointees constitute the majority of the TVA board of directors. Key decisions on TVA’s generating mix are in the works.
For the near term, the initiative has a draft goal of reducing interconnection schedules and costs for large-scale renewable and storage projects by 50% within five years.
A pilot project that enables farmers to shift irrigation pumping to hours with low-cost electricity has saved them money, and in theory has reduced renewables curtailment. The pilot should be expanded to reach farmers statewide, said CalCCA.
Industry participants proposed many solutions this year to speed interconnection studies. Although federal regulators included key solutions in a proposed rule, for now the logjams and cost allocation problems continue.
Requiring smart inverters will enable more customers to install rooftop solar and storage without paying for grid upgrades. New Mexico also enabled interconnection of more storage by following guidance in the Interstate Renewable Energy Council’s BATRIES report.
As trade groups and citizens’ groups advocate for low-cost renewables in state proceedings, they can make a stronger case by preparing their own utility resource plan, for example by using the free GenX model developed at MIT, says nonprofit group RMI.
Solar and wind deployment would increase sharply under the forecast from the National Renewable Energy Laboratory.
To cost-effectively reach a high level of renewable generation, additional transmission will be needed to connect the wind belt in the central U.S. to eastern grids, according to early results from a Department of Energy study.
Pacific Northwest National Lab researchers have developed a framework for compensating energy storage as a dual-use asset, earning revenue both as a regulated transmission asset and as a competitive market participant, while reducing both system and customer costs.
A federal program to help deploy new or expanded transmission capacity will favor transmission projects that will deliver renewable power, because contributing to lower greenhouse gas emissions is one of several evaluation criteria.
