ZBB Energy Corp. (ZBB) Announces Order from Powertech Labs, a Subsidiary of BC Hydro

Nov. 18, 2009 (Business Wire) — ZBB Energy Corporation (NYSE AMEX: ZBB) today announced that following a successful bidding process it has received an order for four (4) standard, modular ZESS 50 energy storage systems (inclusive of power electronics) from Powertech Labs, a subsidiary of BC Hydro, for the Bella Coola Hydrogen Assisted Renewable Power (HARP) project in Bella Coola British, Columbia.

The ZESS energy storage systems will be used as part of a demonstration project that uses multiple components (power generation, utilization, storage, and dispatch optimization) to provide electrical power to an isolated remote area grid with the goal of reducing reliance on diesel generation and the reduction of greenhouse gas emissions in remote communities in British Columbia. The project objective is to increase the utilization of BC Hydro’s Clayton Falls small hydro plant and reduce the reliance on diesel generators at its Ah Sin Heek generating facility.

The ZESS units will be used to store excess power from Clayton Falls, to be later dispatched during periods when Clayton Falls is unable to supply sufficient power to the community (e.g. higher load and/or lower water flow at Clayton Falls). The ZESS 50 storage units system will be interfacing with a smart grid system, in order to optimize the storage and dispatch of power throughout the overall Bella Coola system.

ZBB’s Vice President Sales and Marketing, Mr. Kevin Dennis said, “We are delighted to have been selected by Powertech Labs (BC Hydro) for this demonstration project. We recognize their global reputation as a leader in technology advancement and implementation in the electrical utility industry. Being successfully selected following a thorough evaluation of our technology has shown that the ZESS products integrate effectively with conventional generation systems.”

The HARP Project, managed by Powertech, is supported by BC Hydro, GE, Sustainable Development Technology Canada, an arm’s-length, not-for-profit Corporation created by the Government of Canada, and the Province of British Columbia through the Innovative Clean Energy Fund.
