American Electric Technologies has supplied Siemens Industry with a 1MW Integrated Solar Inversion Station (ISIS) as part of a power purchase agreement with the City of Atwater, California.

Although contract terms have not been revealed, it is understood that the Siemens-owned and -operated 20-year solar project, which powered up in October 2012, will save the city over US$1 million in energy costs.

The 1MW ISIS, along with bundled installation and commissioning services, provides Siemens with a fully integrated product and service offering to help meet their project timelines.

With AETI’s capabilities, Siemens will enable the City of Atwater to reduce costs and meet increased energy demands associated with their new wastewater treatment plant adjacent to the solar project site. The complete solar system will generate 2,221,738 kWh of clean renewable energy annually, and realise significant greenhouse gas emissions savings.
AETI’s ISIS platform is said to be the world’s first 1000V 1MW solar inverter witness-tested to UL1741 by a nationally recognized test lab (NRTL), TUV of North America.  The ISIS system deployed at the Atwater site incorporates an integrated DC master re-combiner, control power transformer, and grid-tie transformer, and was installed by an AETI services team with over 2GW of grid-tie projects to date.
“We are pleased to have been selected by Siemens for their solar project in Atwater, California,” said Kent Breaux, global director of renewables, AETI.

“Partnering with a reputable solar project developer like Siemens allowed us to deliver the customer a superior level of quality service while helping them reduce high energy costs and meet renewable energy goals.”
