ZG Providing Site Reservoir Authority Cost Analysis Services

ZG is providing interconnection and transactional cost analysis services to the Sites Project Authority under contract with Jacobs and CH2M Hill Engineering firms. The Site project is an off system pumped water storage combined with generation to be located near Maxwell California. The project will include roughly 175 MW of pumping demand along with 75 MW of generation.


ZG is working with the site project team to determine the optimal point of interconnections from four separate PG&E l and 3 WAPA transmission lines and has provided cost estimates for the interconnection facilities. Additionally, ZG is conducting a power transaction analysis to quantify the financial picture between a PG&E vs. WAPA connection while participating in the CAISO markets.
