Amid the growing number of initiatives to unlock the benefits of distributed energy resources, states across the U.S. are pursuing measures that support customer-oriented solutions while ensuring reliable system operations.
Energy storage plays a key role in managing the pace of the transformation of the electric system. The versatility of the resource has allowed for multiple grid roles, including supporting transmission reliability.
The focus on decarbonization and energy security has elevated the importance of nuclear power as a critical technology to achieve national and state goals. Recent actions include the second award cycle of a $6 billion federal program established to maintain the existing reactor fleet and proposals to explore the feasibility of deploying advanced nuclear technologies.
Stringent climate policies have prompted discussions around comprehensive cap-and-invest programs to address emissions across multiple sectors. Several U.S. states have devised bold climate action plans that call for transformations across industry, energy, and transportation sectors.
Recent long-term resource plans of several electric utilities include accelerated timelines to develop renewables or retire coal-generation fleet, reflecting the impact of policy changes ensuing from 2022 Inflation Reduction Act (IRA). The IRA includes provisions to support the transition of the U.S. electricity generation fleet to cleaner energy sources and lower carbon emissions.
Net metering policies, which have been instrumental in driving the growth of distributed solar across the U.S., are poised for further evolution as states explore a holistic approach to establish compensation mechanisms. In California, a long-time leader in solar adoption, regulators have approved a significant overhaul of the net metering program, a decision that will likely have broad implications for the industry nationwide.
Demand response (DR) continues to garner attention as a key reliability tool amid the ongoing transition to renewable energy, increased electrification, and extreme weather. Traditionally intended to shed load and prevent blackouts during peak demand periods, DR is increasingly valued for its ability to address imbalances caused by the variability in wind and solar generation.
Coal accounted for the largest share of electricity generation in 15 U.S. states during 2021, according to a report published on Dec. 7 by the U.S. Energy Information Administration. The number of states using coal as compared to other energy sources has declined from 32 in 2001, with the U.S. shifting away from coal generation…
As the transition to a carbon-free grid relies on the integration of diverse renewable energy resources, the need for long-duration energy storage has become more essential. Storage systems capable of supplying energy for 10 hours or more, or adequate stored energy to provide firm capacity to the grid have been garnering attention to accommodate renewables and support grid stability.
Efforts to preserve and expand the U.S. nuclear fleet are figuring more prominently across the U.S., spurred by the growing demand for emission-free energy. In particular, policy actions and initiatives are geared towards making nuclear power more competitive.
