GRU Pays Customers for Solar Energy

Customers with Solar Electric Systems can sell GRU their extra energy

GRU can interconnect our customers' solar electric systems to our electric distribution system through dual metering. Customers will be paid for all energy generated by their systems that is not used within their buildings.

To measure the electricity, we use a meter with two registers. One measures the energy flowing from GRU to the building. The other measures the amount of electricity that flows from the building to GRU, for which we pay an average of 5.5 cents per kilowatt hour. We've operated our own solar electric system for seven years and have offered dual metering since March 2002.

Customers must apply for interconnection. Once approved, the solar electric system may be installed. The systems cost from 19 to 47 cents per kilowatt hour to use, according to the State of Florida Public Service Commission. GRU does not install the systems, but a contractor with a solar license is recommended for installation. The state's Construction Industry Licensing Board provides a list of certified solar contractors.

When completed, the system must be approved by GRU to meet certain safety requirements, such as ensuring that the solar electric system will shut down if our utility grid shuts down (or we lose power in the area). In addition, $100,000 of liability insurance is required, and a building permit must be obtained. After installation, GRU will inspect the solar electric system and usage may begin following approval.
