Storage and energy management installed at 9 MW PV plant in Pennsylvania

Battery developer and energy storage company Axion Power International has been chosen to supply its PbC technology and batteries for a 48-acre solar PV plant in Pennsylvania.

The 9 MW solar plant will become the largest in the state once completed, with construction scheduled to begin before the end of the year. Axion’s batteries will be complemented by the company’s Power PbC PowerCube, which will provide frequency regulation to the plant.

Phases I and II will comprise the first 2.4 MW of solar capacity, generating 6.3 million kilowatt hours of clean solar power that will be sold to the Coatesville Area School District (CASD) via a 25-year PPA. The Coatesville Solar Initiative (CSI) will own the plant.

Once the project has reached its full potential, Axion’s batteries could be used to store the output from the 5,000 to 6,000 range, based on the proposed size of the plant. CSI was first alerted to Axion¬ís prowess in battery technology in 2013, having been referred by local EPC Keares Electrical Contracting.

"Axion has proven to be a significant resource to CSI and Keares Electrical Contracting these past two years," said Keares Electrical Consulting president Bob Keares. "Axion technology, industry contacts and knowledge will contribute significantly to the Coatesville farm coming to fruition."

Axion has spent the past decade developing its PbC batteries and technologies, creating 13 patents during that time and developing nearly 100% recyclable batteries. "As Axion emerges into full commercialization, the partnership with CSI is a milestone in industry acceptance," said Axion CEO David DiGiacinto.

"A solar farm that will generate more than 9 MW of electricity is an important step for the renewable energy industry in Pennslyvania," DiGiancinto added. "We believe that the PbC storage and frequency regulation capability will shorten the payback time for the entire installation significantly."

According to Axion, its PbC battery technology is one of only a handful of advanced batteries that can be assembled on existing lead-acid battery production lines utilizing the company’s proprietary activated carbon electrodes.
