Energy Demand Management

Energy Demand Management at Water Districts

For many municipalities, drinking water and wastewater plants are typically the largest energy consumers, often accounting for 30-40% of total energy consumed. Overall, drinking water and wastewater systems account for approximately 2% of energy use in the U.S., adding over 45 million tons of greenhouse gases annually. To reduce energy costs, water and wastewater treatment plants must understand their electric utility rates and structures and be able to balance energy costs with the demands of the facility. Helio Energy Solutions has helped water districts with their energy demand management since 2001.

Energy Demand Management for Water Districts provided by Helio Energy Solutions

Lowering Emmissions

PredictEnergy’s analytics module, leverages real-time energy analytics to develop an energy demand management approach that adapts to changing energy and power demands throughout the day. Changing energy rate structures for Water Districts' potable and recycled water systems create challenges and opportunities to support the grid and simultaneously reduce energy costs for rate payers. PredictEnergy® analytics enables Water Districts to visualize their operations from an energy cost perspective while minimizing the impact on plant operations . PredictEnergy® applies visualization to complex and dynamic utility rates so plant operators can “see” current efficiency and production and next steps.

Notwithstanding the complexity of water districts, the plan is simple: When energy is in high demand and expensive, plant operators shift processes to minimize power requirements, when energy is in surplus, operators adjust to bolster storage in anticipation of the next demand.

Water District Energy Demand Management

In a contract awarded by the California Energy Commission (CEC), UC Davis’ Center for Water and Energy Efficiencywill 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.

By incorporating energy efficiency practices into their water and wastewater plants, municipalities and utilities can save 15 to 30%, saving thousands of dollars with payback periods  of only a few months to a few years.  Helio Energy Solutions has helped numerous water districts around the country develop a better understanding of their energy intensity and an action plan to improve their energy efficiency and overall cost of energy.
