Developing Tools and Strategies for Improved Water Utility Energy Efficiency and Integrated Water-Energy Planning
Energy is usually the second-highest cost item of a water utility’s operating budget. Many opportunities exist for the design and operational optimization of electricity use for water supply and treatment. The energy landscape is rapidly changing due to climate change impacts, state legislative incentives for energy efficiency, increasing use and decreasing cost of renewable energy, and the politicization of climate change. For these reasons, this Research Area was initiated in 2012. Since then, eight projects were funded under this Research Area and much progress has been made in advancing knowledge related to the three objectives below. The Research Areas was discontinued in 2017 but there is potential for another energy-related Focus Area in the future.
Research Area Objectives
- Provide data, tools and knowledge for water utilities to reduce energy demand and energy costs.
- Identify and demonstrate opportunities for water utilities to optimize use of renewable energy.
- Identify opportunities to integrate multi-sector basin-wide planning across all water user groups (i.e., urban, agricultural, power) and energy providers to result in integrated water-energy planning.
