One gigawatt of solar power shines in PJM

Put on your shades, folks, PJM Interconnection this month passed the one gigawatt (GW)—one billion watts – milestone for solar power in its region. One gigawatt of electricity generated would power between 800,000 and one million homes.

Solar power more than doubled in PJM in each of the last two years and continues to grow. The map below shows the amount of solar capacity by county in PJM’s region.

Installed Solar Capacity in PJM

A number of states in PJM follow renewable standards and goals. The map below illustrates these goals.

This map is from www.dsireusa.org and appeared in PJM’s Regional Transmission Expansion Plan for 2011.

Businesses and homes which can generate at least one megawatt-hour of power from solar energy can qualify to capture credit for the megawatt-hour as a solar renewable energy credit (REC). The solar REC can be traded or sold to another entity to satisfy its compliance with state goals. PJM Environmental Information Services (EIS), a subsidiary of PJM, administers the registry, the Generation Attribute Tracking System (GATS), which tracks and records RECs.

PJM’s Renewable Energy Dashboard provides a snapshot of how much renewable energy is available in PJM and proposed to be built in the region.
