Case Study

The right renewable energy solution for San Diego

The San Diego Water Authority had issued a request for proposals on the design and construction of a new renewable energy generation and storage facility at its Twin Oaks Valley Water Treatment Plant (WTP). Receiving numerous bids that required thorough review, and recognizing the high complexity of the task, the San Diego Water Authority chose an expert panel provided by Solved to lead the evaluation process. The aim was to identifying technologies that minimize installation and operating costs, while maximizing avoided cost and renewable opportunities for the Water Authority.
