February 16, 2022 – Convergent Energy + Power—a provider of battery energy storage system (BESS) solutions—announced that the industrial-scale BESS it developed for NSG Group’s Pilkington Glass Facility (Collingwood, Ont.) is operational.

The 5-MW/10-MWh BESS is the first for NSG Group. It leverages Convergent’s Peak IQ software solution to reduce the facility’s electricity usage during the costliest grid peaks.

The BESS takes approx. 50% of Pilkington’s demand offline, replacing that power from the batteries directly, saving the facility $1 million per year.

“Locally, this battery storage system is part of our commitment to support our community in Collingwood and the broader efforts in Ontario to create a more-efficient, sustainable grid,” said Ron Young, Collingwood’s engineering group leader.


“NSG Group has been an excellent partner from start to finish, and demonstrated a deep commitment to all of its stakeholders,” said Johannes Rittershausen, CEO of Convergent. “For this particular project, I’m proud to say our team navigated a global pandemic, and additional safety regulations, to bring the battery system online as safely and quickly as possible to achieve success.”

The BESS is interconnected to the EPCOR electricity distribution system, adds Convergent. The integrated storage solution employs SMA inverters and Samsung SDI batteries, which were supplied by IHI Terrasun Solutions. WSP’s Power T&D team provided feasibility and detail engineering services. S&T Group performed site installation. Rodan Energy Solutions–Power Systems Group supported with system commissioning. WESCO Distribution Canada supplied S&C Electric Canada switching and power distribution equipment. Composite Power Group supplied transformers manufactured by Rex Power Magnetics and Northern Transformer.
