Installation Standards for Distributed Generation

Con Edison is committed to delivering clean energy to its customers, and to supporting New York City and New York State clean-energy initiatives. This includes facilitating installations for customers wishing to install distributed generation facilities including photovoltaics, and combined heat and power such as microturbines. The company provides net-metering installations for customer-installed renewable energy sources including solar, wind, and biogas. To date, net-metering installations have been made mostly in homes and small commercial facilities that have built photovoltaic installations to provide electricity. When the photovoltaics generate more energy than the facility consumes, the company's net meters monitor the flow of the surplus back into the grid. When the photovoltaics generate less energy than the facility consumes the net meter records how much energy is drawn from the grid. Customers pay only for the net total electricity drawn from the grid at the end of every month, which greatly helps the economics of the photovoltaic installation.

In addition, Con Edison of New York is helping develop the New York State standard interconnection requirement for distributed generation with generating capacity of 2 MW or less. Recently, the company collaborated with the New York City Department of Buildings Co-Generation Task Force to develop standards for installing gas-fired microturbine generators and other types of generating equipment in New York City. Microturbine systems generate electricity very efficiently and the residual heat they produce can be used for heating and hot water. By establishing this pioneering standard, Con Edison of New York has facilitated the use of these systems in the city.

The real benefit of this installation standard is that it paves the way for installing advanced distributed-generation technologies under development. Con Edison's work makes New York City ready for adapting distributed generation equipment for a more sustainable future.
