Through the High Penetration Solar Deployment program, DOE is funding solar projects that are accelerating the placement of solar photovoltaic (PV) systems into existing and newly designed distribution circuits in the electrical grid.

The High Penetration Solar Deployment projects are working with teams that include utility partners to model, test, and evaluate solutions to mitigate the impact of large amounts of PV-generated electricity on the reliability and stability of the electric power system. Some of the issues associated with high PV penetration include voltage regulation, reverse power flow, unintentional islanding, unbalanced loads, and communications. Each team is evaluating high PV penetration and/or energy storage on utility feeders to develop accurate, validated models and system analysis tools, and in some cases advanced equipment, to facilitate reliable, widespread solar system deployment.


In May 2009, DOE announced funding for the following Systems Integration projects. This investment is part of $117.6 million in American Recovery and Reinvestment Act funds.
