Great River Energy and NRECA Co-Sponsor Research Regarding Underutilized Energy Storage Resources
The National Rural Electric Cooperative Association (NRECA) and Great River Energy co-sponsored a research study that showed that residential electric water heaters can serve as energy storage for wind or solar power, increasing efficiency, better integrating renewable energy and saving customers money. The large capacity water heaters can be enabled to make immediate use of wind or solar power to heat the water and then be shut down when renewables are scarce and wholesale costs are high.
