Project Info COMPLETE Project Title

Emerging Technologies Water Energy Pilot Implementation at San Jose Water Company

Project Number PGE 0901 Organization PG&E End-use Plug Load Sector Industrial Project Year(s) 2009 - 2010

Project Summary


This report presents a feasibility study for implementing an energy-pumping optimization algorithm through a Supervisor Control and Data Acquisition (SCADA) System using real-time energy consumption data.  The study was performed as a collaboration between the San Jose Water Company (SJWC), Pacific Gas and Electric Co. (PG&E), and BASE Energy, Inc. (BASE) over the period of one and a half years.

Four well pump stations at SJWC were selected for the study: two single well pump stations, one two-well pump station, and one multiple well pump (4 well pumps and three booster pumps) station.  The main results of this study were:


• The utility revenue meter energy data can be used to optimize the water pumping energy;

• The utility revenue meter can be easily interconnected to a SCADA system to supply real-time energy data; and 

• A water pumping energy optimization methodology that utilizes real-time energy consumption data can result in electrical energy savings.
