As of June 15, 2012, MMWD’s solar photovoltaic arrays on the Administration Building and in the Corporation Yard have generated a combined 1,000 MWh of clean, renewable energy. The solar arrays were installed during the summer of 2009 and began operating in August and September of that year.
The Corporation Yard arrays, which supply all the buildings except the Water Quality Lab and the Operations Center, have produced slightly over 100 percent of the energy needs for that portion of the Yard. The Administration Building array has produced about 45 percent of the energy use of the district’s office building.
In addition, by this coming month MMWD will have enrolled all of its 236 electric accounts in Marin Clean Energy’s “Light Green” 50 percent renewable electricity option. The district began using Marin Clean Energy in 2010 and converted 203 accounts by last year. Now that Novato, Ross, Larkspur and Corte Madera have joined Marin Clean Energy, we are able to convert our remaining accounts. Most of the energy MMWD uses is for pumping water into and throughout our 147-square-mile service area.
