India is hoping to achieve 40% renewable electricity capacity and add 450 GW of renewable energy to its grid by 2030. A key element to its grid planning is the incorporation of distributed energy resources (DERs), including solar, storage, and electric vehicles. To do that, NREL researchers worked with Indian utilities to develop and adopt tools for data management, DER risk analysis, and load distribution assessment that will optimize DER growth and support a more sustainable power system for the future.
How Will the 2024 Solar Eclipse Impact the Power Grid? Join an Upcoming Webinar to Find Out
On April 8, 2024, a total solar eclipse will traverse North America, affecting solar power plants across 12 U.S. states for up to two and a half hours. To evaluate the grid impacts of the eclipse, NREL partnered with the North American Electric Reliability Corporation and the U.S. Department of Energy Solar Energy Technologies Office, expanding on prior research completed for the August 2017 eclipse. The 2024 Solar Eclipse Study includes assessments of the impact of the eclipse on reducing production from both utility-scale photovoltaics (PV) and distributed PV across all three interconnections, with detailed regional-level modeling of the Eastern Interconnection.
The 2017 North America total solar eclipse came and went with minimal impact to the power grid. Since 2017, solar installations have almost tripled in the U.S. and a larger impact on solar generation is expected. This study is focused on the potential risks and mitigation methods for grid operation during the 2024 solar eclipse.
NREL is hosting a webinar on April 2 to present the study findings. The webinar will feature interactive and detailed grid visualizations, as well as summary information for balancing areas and independent system operators, helping utilities and operators anticipate the impact they will experience on that exceptional day of the eclipse.

Determining and Unlocking Untapped Demand-Side Management Potential in South Africa: Demand Response at the Grid Edge, NREL Technical Report (2024)
South Africa is currently experiencing an energy crisis. The principal challenge is the low energy availability factor of the coal-fired component of the existing generation capacity. These shortages are due to a combination of unplanned breakdowns and maintenance and units being out of service for planned maintenance. The energy crisis in South Africa is a supply-side problem, as the country has excess installed dispatchable generation capacity of 48.3 GW compared to a peak demand of 34.4 GW in 2022. This report presents a comprehensive examination of possibilities for demand-side management programs for South Africa.
Major Drivers of Long-Term Distribution Transformer Demand, NREL Technical Report (2024)
Distribution transformers, used to step down medium-level voltage to service-level voltage for end-use electrical consumption, are currently experiencing an unprecedented imbalance between supply and demand. Utilities are experiencing extended lead times for transformers of up to 2 years (a fourfold increase from pre-2022 lead times) and reporting price increases by as much as 4–9 times in the past 3 years. The supply of transformers is critical for the reliability and growth of the power system. Additionally, supply chain issues, if not resolved, could impact climate goals with respect to the electrification of demand and the growth of renewable energy. This report summarizes the initial analysis conducted by NREL, supported by the DOE Office of Electricity and Office of Policy, to assess the long-term drivers of demand for distribution transformers.
