Worldwide Best Practices Integrate Renewables in Electricity Markets


An NREL report proposes best practices for governments to enable renewable electricity grid integration:

  • Coordinate and integrate planning
  • Develop rules for market evolution, enabling system flexibility
  • Expand access to diverse resources
  • Improve system operations. facilitates access to data and empowers the energy community to use and contribute to the collection.


Energy investors can use OpenEI's data to:

  • Determine how many turbines could be installed on a wind farm
  • Learn about solar, biomass, or geothermal energy resource potential
  • Gain access to cost data on generation sources, fuels, and vehicles.

How will our grid infrastructure accommodate increasing amounts of renewable energy?


NREL has two models that examine the operation of the electrical grid when connected to renewable systems:

  • ReEDS, the Regional Energy Deployment System, which looks at the build-out of generation and transmission systems

  • FESTIV, the Flexible Energy Scheduling Tool for Integration of Variable Generation, which examines the impacts of variability from energy sources.

Learn more about ReEDS and FESTIV.

In 2050, what percentage of U.S. electricity generation could renewable energy provide?


NREL's Renewable Electricity Futures Study shows that commercially available renewable energy technologies, combined with a more flexible electric system, could supply 80% of U.S. electricity by 2050.
