Solectria Renewables Awarded $2.1 Million U.S. Department of Energy Contract

to Develop Integrated Smart-Grid Ready PV Inverters with Utility Communications (RELEASE DATE: 9/6/11)

Solectria Renewables, LLC, the leading U.S. PV inverter manufacturer, announced today that it has been awarded a $2.1 million U.S. Department of Energy (DOE) contract to develop integrated smart-grid ready photovoltaic (PV) inverters with utility communications in partnership with the Electric Power Research Institute (EPRI), Detroit Edison, National Grid and Xcel Energy. The awarded contract is part of the DOE's SunShot Initiative which accelerates the development of cost-competitive solar technologies.


This program will demonstrate smart‐grid ready inverters with grid support functionality and required communication links with utilities to capture the full value of distributed PV. The key objectives of this program are to leverage ongoing investmentsin smart grid and related standardsand to expand PV inverter capabilities, which together will enable grid operators to better utilize these grid assets. The main elements in this project are: head‐end communications at the utility operations center; integration into the Distribution Management System (DMS); back‐end PV plant master controller; and smart‐grid functionality built into the inverters.

"We are honored to have been selected by the Department of Energy to receive this award, which is a reaffirmation of our leadership in the inverter space," said Michael Zuercher-Martinson, CTO of Solectria Renewables. "Enabling utilities to control our SMARTGRID inverters (SGI) is the next big step towards a smarter grid that can accommodate a very high PV penetration density in a safe, secure, efficient and reliable manner."

Today's utility scale PV inverters are not well integrated with existing DMS control distribution switches, load‐tap changers, capacitor banks, and other circuit operation distributed resources. Under this contract, EPRI and Solectria Renewables will integrate the DMS, enabling utilities to communicate different operating objectives such as a normal mode, with no disturbances, energy conservation mode, demand reduction mode, or grid‐level emergency mode. This is essential to avoid operational problems and additional costs while reducing inverter maintenance.

Detroit Edison, National Grid and Xcel Energy will supply test sites ranging from 605kW to 30MW. Each of the sites will test different aspects of the aforementioned technologies being developed by EPRI and Solectria Renewables.

The completed program will demonstrate end‐to‐end communication connectivity and control between the utility operations and distributed resources by developing DMS, the communication head‐end at utility operation center, substation DER SCADA, (e.g. the communication path), back‐end plant master controller and inverters with smart‐grid functionality.
