Energy Efficiency

Providing options to help manage customer-side energy consumption and power demand can be important aspects of utility resource planning. Utilities can offer incentives or design rates to help customers utilize their electricity resources more efficiently. Energy efficiency (EE) generally refers to devices (measures) that use less energy to provide the same or better service (e.g., efficient windows will result in lower energy consumption of a home while increasing comfort levels).

Demand response (DR) is another aspect of managing consumption. However, DR programs assist in managing peak demand (kW) rather than overall consumption (kWh). DR can help with utility load aspects such as peak-shaving and load leveling.

EES Consulting has assisted a wide array of utilities with their energy efficiency and demand side planning efforts. We can work with your staff to optimize energy efficiency resources and budgets.

Grays Harbor PUD Integrated Resource Plan

EES Consulting prepared Grays Harbor’s 2020 Integrated Resource Plan. Grays Harbor is required to submit an IRP to the state of Washington every two years that demonstrates how it will meet the electric power needs of its members with a reliable supply of power delivered in the most cost-effective manner. The 2020 IRP was an evaluation of resource alternatives that could be deployed to meet Grays Harbor’s load and meet state of Washington renewable energy requirements under the Energy Independence Act and carbon-free energy requirements under the Clean Energy Transformation Act. Grays Harbor embarked on an IRP to study alternative sources of supply that could best serve its customers’ needs for the period 2021-2040.

Los Angeles County Aliso Canyon

The County of Los Angeles asked EES Consulting to evaluate alternatives to mitigate the need to withdraw natural gas from the Aliso Canyon storage facility. The facility was used to supply gas during peak winter usage as well as to supply natural gas-fired generators during peak summer demand, but it was shut down after a massive leak released more than 100,000 metric tons of methane. EES found that measures put in place by utilities in Southern California to maintain system reliability without utilizing Aliso Canyon were working, and that resuming natural gas injections was unnecessary in the near term. In the longer term, the acquisition of demand response, energy storage, and energy efficiency could effectively displace the need for Aliso Canyon. EES also provided a series of recommendations to improve the implementation of the mitigation measures. (Image:Earthworks)
