Eaton Corporation Collaborates with Tangent Energy Solutions to Build Largest Solar PV Installation in Western Pennsylvania

Arrays at Two Facilities Will Generate Approximately 1.5 MW of Solar Energy

PITTSBURGH … Eaton Corporation and Tangent Energy Solutions today announced a collaboration to develop solar energy generation installations at Eaton's facilities in Coraopolis and Vanport Township, Pa. The project will include a 1.3-megawatt (MW) ground mount solar array at Eaton's Beaver facility and a 200-kilowatt (kW) rooftop array in Coraopolis. The array constructed at Eaton's Vanport Township facility on Georgetown Lane will be the largest solar installation in western Pennsylvania to date.

Solar power will contribute about 25 percent of the electricity used by the Vanport facility. Both arrays will provide Eaton with 1.76 million kilowatt-hours (kWh) of clean electricity per year and will displace 2.7 million pounds of carbon dioxide and other greenhouse gases per year, which is the equivalent of removing 238 cars from the road.

In addition to the considerable environmental benefits, the project is projected to save Eaton energy costs over the term of twenty years. Tangent, headquartered in Kennett Square, Pa., will monitor and maintain the solar assets for Eaton over the lifetime of the project. The project will also support jobs in western Pennsylvania through the use of local and regional construction companies.

"We chose Tangent for this project because they understand the more complex energy systems of large, industrial companies," said John Vernacchia, manager, Renewable Energy Segment, Eaton. "Their comprehensive solution will improve our costs now and in the future, while reinforcing our commitment to the environment."

On-site solar generation assets will be provided by Tangent at no capital cost to Eaton who will purchase the energy produced at a set rate through a long-term Power Purchase Agreement (PPA).

Eaton will supply Power Xpert solar inverters, electrical disconnects, combiner boxes and other equipment for the project. Eaton will also staff the engineering services and construction management teams. The system's solar panels were provided by Motech Industries in Newark, Del.

"This agreement is another example of Eaton's leadership in sustainable, green energy solutions and we're thrilled to be collaborating on these projects," said Dean Musser, president and chief executive officer, Tangent Energy Solutions. "The natural fit of Eaton's equipment, engineering and construction capabilities, with our development, technology and energy experience was the success formula for these projects."

Site clearing in advance of construction began last week with an expected completion date of November 30, 2012.

Project financing was provided by Laurel Capital of Radnor, Pa. and First Niagara Bank of Buffalo, N.Y. The project is also being financed in part by a grant from the Commonwealth of Pennsylvania, Commonwealth Financing Authority.

GreenFasten™ solar panel roof mount hardware, watertight, USA made

GreenFasten™ solar panel roof mount hardware, watertight, USA made

The GreenFasten™ - GF1 system utilizes the patented watertight technology EcoFasten Solar® is known for. The flashing is fit with our EPDM rubber bushing and when used with a compatible EcoFasten Solar compression bracket (milled with countersink), a watertight seal is created, which protects the integrity of the roof. Requiring just a single fastener (lag bolt or self-drilling), GreenFasten provides the fastest install in the industry and will not void roofing manufacturer's warranties. Backed by IAPMO certification, GreenFasten delivers a mounting solution for all new or existing (retrofit) composition shingle roofs, and is the most cost-effective solution available. Like all of the solar roof mount solutions in our line of products, GreenFasten is made in the USA using recycled materials.
