Washington Gas Energy Systems Celebrates Completion of Solar Projects Totaling More Than 15 Megawatts in Georgia

Company Holds Ribbon Cutting Ceremonies in Donalsonville, Richland and Greenville

 DSC00292McLean, Va. – December 16, 2014 – Washington Gas Energy Systems, Inc., a subsidiary of WGL (NYSE: WGL) today announced the completion of 20 solar projects, totaling more than 15 megawatts, that will produce renewable energy for Georgia Power. The company held ribbon cutting ceremonies at their sites in Donalsonville and Richland, Ga. on Thursday, Dec. 11, and another event in Greenville, Ga. on Friday, Dec. 12.

“These projects significantly increase renewable energy capacity in the state through the Georgia Power Advanced Solar Initiative,” said Sanjiv Mahan, chief operating officer of Washington Gas Energy Systems. “We commend this program for spurring economic growth in the solar energy industry while reducing the carbon impact of Georgia Power customers, and look forward to completing more projects through this partnership with our diversified offerings across the energy eco-system.”

All of the solar arrays will be owned and operated by Washington Gas Energy Systems under 20-year Power Purchasing Agreements (PPAs) with Georgia Power. The project in Donalsonville is a 2-megawatt ground-mounted system composed of more than 6,000 solar panels, and is expected to produce more than 3,000-MW hours of electricity annually. The project was developed by Office of Solar Development and all engineering, procurement and construction was performed by Cantsink Manufacturing.

The Greenville project is a 1-megawatt ground-mounted solar away at the Meriwether County Industrial Development Authority. It is composed of more than 3,000 solar panels and expected to produce more than 1,500-MW hours of electricity per year. Engineering, procurement and construction was managed by Hannah Solar.

In Richland, the 1-megawatt solar project consists of more than 7,000 solar panels and is expected to produce more than 1,500 megawatt hours of electricity per year. The project was developed by Inman Solar in collaboration with the City of Richland and the Richland Development Authority.

Other Washington Gas Energy Systems projects under construction in Georgia include sites located in Montezuma and Homer, each sized at 1-megawatt.  All projects are expected to be completed by February 2015.

Washington Gas Energy Systems to Evaluate Battery Storage System in Cedartown, Ga.

IMG_1551WGL Holdings Inc., through its subsidiary, Washington Gas Energy Systems (WGESystems), announced an agreement with Southern Company and the Electric Power Research Institute (EPRI) to test and evaluate a battery storage system at a 1-megawatt (MW) solar array in Cedartown, Ga. The project will analyze a 1-MW/2-MWh lithium ion battery energy storage system to establish a technical and economic foundation for future grid deployments, with a specific focus on renewable integration.

“The continued research and evaluation of battery storage is a key component to increasing the feasibility of solar energy for individuals, businesses and municipalities,” said Sanjiv Mahan, chief operating officer of Washington Gas Energy Systems. “We are committed to renewable energy innovation and look forward to teaming with Southern Company and EPRI to test the battery energy storage system in Cedartown.”

Energy storage systems provide collected electricity to the grid on demand to compensate for the intermittence of solar, stabilizing power output from solar arrays and other renewable energy sources. The ground-mounted solar array consists of 3,388 solar panels with an expected annual output of more than 1.5 million kilowatt hours, and covers approximately 6 acres of land. The Cedartown energy storage system is scheduled for commissioning in the second quarter of calendar year 2015.

“We are at a stage in the industry where we need to develop the integration requirements for energy storage systems – the control system requirements, the protection requirements and the modeling requirements – to make them part of system planning and operations,” said Mark McGranaghan, vice president of power delivery and utilization research at EPRI. “This has to happen before they are needed for widespread deployment. Demonstrations like this are absolutely key to establishing these models and requirements.”

The Cedartown solar photovoltaic (PV) facility is part of Southern Company subsidiary Georgia Power’s Advanced Solar Initiative, which was designed to tap into Georgia’s competitive solar marketplace and cultivate cost-effective options for Georgia Power customers. Washington Gas Energy Systems owns and operates the array under a 20-year power purchasing agreement. Inman Solar designed and installed the system. Polk County owns the property on which the systems are built. The solar array is located at 151 N. Park Blvd. in Cedartown.
