San Francisco's Public Utilities Commission (SFPUC) is set to enhance the reliability of its electric grid with the approval of $2.4 million in reserve funds for the Transmission Lines 7 and 8 upgrade project. This decision was made during a recent government meeting, where SFPUC representatives outlined the project's significance and funding sources.

The funds, which are not derived from city general funds or ratepayer contributions, come from mitigation payments made by renewable energy developers. These payments are required to offset the impacts of their projects on existing power infrastructure. The total estimated cost of the upgrade project is approximately $35.4 million, with the SFPUC expecting to receive around $33.3 million in mitigation funds.

Construction on the project began in September 2022 and is scheduled for completion by June 2024. The upgrades will involve modifying existing towers and reconductoring transmission lines to ensure the stability of the grid as new energy generation projects come online. To date, the SFPUC has secured mitigation agreements with 15 developers, totaling about $29.1 million, with additional agreements still in negotiation.

This funding release marks the fourth request for financial support for the Transmission Lines 7 and 8 project, bringing the total approved funding to approximately $28.4 million. The project is currently 88% complete, with costs having decreased by $1.9 million since the last report due to reduced project contingencies.

As the SFPUC continues to manage the integration of new energy sources into the grid, the release of these funds is a critical step in maintaining the reliability and efficiency of San Francisco's power infrastructure. The commission remains committed to executing and collecting funding from mitigation agreements to support ongoing upgrades and ensure the stability of the electric grid.
