Ameresco Provides Southern California Edison (SCE) Project Update

FRAMINGHAM, M.A. – April 10, 2022–Ameresco, Inc. (NYSE:AMRC), a leading cleantech integrator specializing in energy efficiency and renewable energy, today announced updates on recent communications with the battery supplier for Ameresco’s battery energy storage systems (BESS) projects with Southern California Edison Company (SCE). Due to the COVID-19 lockdowns in several regions around China, the supplier has indicated to Ameresco an adverse impact on the supplier’s ability to deliver batteries on the agreed upon timeline. In addition, newly implemented Chinese transportation safety policies may cause delays in the shipment of a portion of the batteries.

Ameresco has been evaluating the circumstances described in the supplier’s communications as well as the impact they may have on the timeline for the BESS projects. Although these circumstances may prevent Ameresco from fully completing all three BESS projects by August 1, 2022, Ameresco believes that the events described in the communications constitute force majeure events under Ameresco’s Turnkey Engineering, Procurement, Construction and Maintenance Agreement dated October 20, 2021 with SCE (the “EPCM Agreement”). Ameresco has accordingly notified SCE and is in communications with SCE and the supplier about the circumstances. Under the EPCM Agreement, the guaranteed substantial completion date for the BESS projects can be extended without the imposition of liquidated damages in the event of a force majeure event.

Against market challenges, significant milestones have already been achieved in the BESS projects, including securing high and medium voltage transformers, auxiliary transformers, inverters, all switchgear and ancillary equipment. Construction related activities are proceeding at all project sites in preparation for battery delivery. Ameresco is also actively working with its suppliers and SCE to avoid or mitigate potential delays, including working with the Port of Long Beach on expedited ship and container handling.

Ameresco continues to monitor developments in China and their potential effects on the BESS projects. Based on its current visibility, Ameresco does not expect potential battery supply delays to materially impact 2022 results and reaffirms the annual earnings guidance announced on February 28, 2022.

Ameresco expects to provide further updates and outlook regarding the BESS projects, when it announces financial results for the quarter ended March 31, 2022 in early May.
