In a press release on 21-Oct-14, AltaGas Ltd. announced that its 195 megawatt Forrest Kerr run-of-river hydroelectric facility had initiated the final phase to achieve contractual Commercial Operations Date (COD). The requirement involves a 72 hour period of testing to meet criteria established and required by BC Hydro.
The press release notes that David Harris, Chief Operating Officer, is pleased with the progress made on Forrest Kerr and is looking forward to achieving COD. He also notes: “While we safely commissioned the plant on time and on budget, we experience some unforeseen challenges including significant transmission line constraints and a flooding event on the Iskut River. Our strong relationship with BC Hydro and our dedicated teams enabled us to overcome these challenges.”
On 30-Jul-14, Forrest Kerr was tied-in and delivering power the Northwest Transmission Line (NTL) at Bob Quinn, British Columbia; however, prior to start-up, AltaGas was notified of constraints to the NTL, which prohibited the systems availability to take full load from Forrest Kerr until 03-Sep-14. Heavy rainfalls and extraordinarily high water levels on the Iskut River in late September, contributed to further delays to reach COD. As a precautionary measure AltaGas removed Forrest Kerr from service until commissioning checks could be completed and all units could be safely restarted. Forrest Kerr returned to service on 11-Oct-14.
