Ridgeline to Evaluate Efficiency Maine Trust’s Weatherization Programs
May 2025 - Ridgeline has been awarded a contract to complete an impact evaluation of Efficiency Maine Trust’s insulation rebate measures from the Home Energy Savings Program and Low and Moderate Income programs from July 2022 through June 2024. We will quantify energy and demand impacts and analyze program cost-effectiveness.
Ridgeline to Support Efficiency Maine’s C&I Custom Program and Large Battery Initiative
April 2025 - Ridgeline has been awarded a three-year contract to provide support services for Efficiency Maine Trust’s Commercial and Industrial Custom Program and the Large Battery Initiative. CollinsCEA joins the Ridgeline team. The C&I Custom Program incentivizes tailored energy efficiency and distributed generation projects that require unique engineering analyses and energy conservation measures that are not covered by prescriptive incentives. The program is open to all C&I customers in Maine, including businesses, institutions, and multifamily property owners. Some of the commonly incentivized measures include process system improvements, compressed air system upgrades, distributed generation systems, HVAC upgrades and controls, and pumping or blower systems. The Large Battery Initiative, within Efficiency Maine Trust’s Demand Management Program, provides performance-based incentives for the installation and dispatch of both thermal and chemical batteries during summer peak demand conditions when anticipated peak demand is greater than 20 kW.
Ridgeline to Evaluate Heat Pump Use in Vermont
May 2024 - Ridgeline has been awarded a State of Vermont contract to evaluate heat pump technology usage in Vermont. The study's purpose is to update the Vermont Public Service Department's 2017 Evaluation of Cold Climate Heat Pumps in Vermont, which focused on mini-splits, the prevailing technology installed in 2017. In addition to updating this report, the study will also examine the use of multi-head and central heat pump systems installed in residential applications and small businesses. Part of this study will include using advanced meter infrastructure (AMI) data to evaluate heat pumps and these data will be compared with metering results to evaluate the accuraacy of AMI analysis.
Ridgeline awarded Rhode Island Renewable Energy Fund Inspection Services contract

Uncertainty Assessment for International Performance Measurement and Verification Protocol (IPMVP)
Efficiency Valuation Organization releases a new IPMVP Application Guide, April 16, 2018
The Efficiency Valuation Organization (EVO) is pleased to announce the release of a new application guide Uncertainty Assessment for IPMVP (EVO 10100: 1:2018). This document is a revised and expanded version of the Statistics and Uncertainty for IPMVP (EVO 10100 1:2014) application guide published in 2014. The new application guide includes examples for each of the four IPMVP options.
M&V efforts are designed to determine energy and demand savings with some reasonable accuracy. However, this objective can be affected by either systematic error (i.e., not occurring by chance, including measurement error) or random error (i.e., occurring by chance and often due to using a sample rather than a census to develop the measured value).
