GPC Term Loan

On June 9, 2020, GPC and the guarantors party thereto entered into a seven-year $900 million first lien senior secured term loan facility and three senior secured revolving letter of credit facilities totaling $200 million. The GPC Term Loan is certified under the Climate Bonds Standard. Any letters of credit issued under the GPC Term Loan letter of credit facilities must be at the request of and for the account of GPC. The GPC Term Loan bears interest, at GPC’s option, at either (i) the Base Rate, equal to the highest of (a) the Federal Funds Rate plus 0.50% per annum, (b) the prime rate published in the Wall Street Journal, or (c) 1.0% plus an applicable margin of 1.0%, increasing by 0.125% every three years, or (ii) LIBOR plus an applicable margin of 2.0% per annum, increasing by 0.125% every three years. The GPC Term Loan matures on June 9, 2027, but may be prepaid at any time upon irrevocable notice to the Administrative Agent. We used a portion of the proceeds from the GPC Term Loan to repay project debt associated with Steamboat as further discussed below.

The GPC Term Loan is secured by certain real and personal property of GPC consisting primarily of the Geysers Assets. The GPC Term Loan is not guaranteed by Calpine Corporation and is without recourse to Calpine Corporation or any of our non-GPC subsidiaries or assets; however, GPC generates a portion of its cash flows from an intercompany tolling agreement with Calpine Energy Services, L.P. and has various service agreements in place with other subsidiaries of Calpine Corporation.

Project Financing, Notes Payable and Other

On June 12, 2020, we used a portion of the proceeds from the GPC Term Loan to repay approximately $342 million in carrying value of project debt associated with Steamboat and recorded approximately $8 million in loss on extinguishment of debt during the second quarter of 2020.

On July 1, 2020, PG&E and PG&E Corporation emerged from bankruptcy. Our Russell City Energy Center and Los Esteros Critical Energy Facility sell energy and energy-related products to PG&E through PPAs. Subsequent to the bankruptcy filing, we received all material payments under the PPAs, either directly or through the application of collateral. As a result of PG&E’s bankruptcy, we were temporarily unable to make distributions from our Russell City and Los Esteros projects in accordance with the terms of the project debt agreements associated with each related project. Under PG&E's plan of reorganization, our PPAs were assumed and any restrictions on distributing cash from our Russell City and Los Esteros projects were cured. Additionally, the forbearance agreements associated with our Russell City and Los Esteros project debt agreements were terminated in accordance with the terms of the agreements. Accordingly, following removal of bankruptcy proceeding restrictions, our Russell City and Los Esteros projects will distribute funds in the amount of $88 million to Calpine Corporation in August 2020.
