Ecological Impact

Moulton Niguel Water District's solar power system will produce enough clean electricity to offset any one of the following over the 25 year life of the system:

The carbon sequestered by

seedlings grown for 10 years.

bottles of BBQ propane burned.

Moulton Niguel Water District Energy Management

In a contract awarded by the California Energy Commission (CEC), UC Davis’ Center for Water and Energy Efficiency will be running a project with Helio Energy solutions at the Moulton Niguel Water District to better understand how water utilities can become a key tool in helping California manage its roller coaster electricity supply-and-demand challenges.

Over the next three and a half years, researchers at UC Davis will utilize Helio Energy Solution’s PredictEnergy software platform to develop technologies and processes to integrate California’s water infrastructure with the electrical grid. The Moulton Niguel Water District in Laguna Niguel, has volunteered as the proving ground for a cutting-edge approach to respond to the daily ebb and flow of the State’s energy consumption as weather patterns place changing and challenging demands on available energy.

Moulton Niguel Water District spends approximately $2 million per year to power its water services for 170,000 customers in South Orange County. CWEE researchers will combine water system hydraulic modeling with Helio Energy Solution’s software platform to create a demand management system that supports grid health and simultaneously reduces Moulton Niguel’s energy costs.

The Solution

moulton niguel water district energy demand management with UC DavisThe project will use PredictEnergy’s software analytics module, leveraging real-time energy analytics to develop an energy management approach that adapts to changing energy demands throughout the day.  Changing energy rate structures for Moulton Niguel’s potable and recycled water systems create challenges and opportunities to support the grid and simultaneously reduce energy costs for rate payers. PredictEnergy analytics enables Moulton Niguel to visualize its operations from an energy cost perspective. It will apply complex and dynamic utility rates and visualization so plant operators can “see” current efficiency and production.

While the system is complex, the plan is simple: When energy is in high demand, plant operators shift processes to minimize power requirements, when energy is in surplus, operators adjust to bolster storage in anticipation of the next demand.

“We want to develop a strategy that meets the needs of the grid and pays off for water utilities at the same time.” Said Mike Murray, President of Helio Energy Solutions, “By partnering with UC Davis and the Moulton Niguel Water District, we will be able to provide our State with a solution that reliably and safely delivers results while incentivizing water districts to participate.  We look forward to working together on this exciting new project.”
