About the data:

Efficiency Vermont provides energy efficiency services, financial support, objective advice, technical assistance, and cost-effective energy solutions for Vermont homeowners and businesses in every county. Efficiency Vermont receives billing data (customer information and monthly usage data) from Vermont electric distribution utilities for the purpose of supporting energy efficiency programs and services. As a result, the accuracy of customer counts and consumption data contained in this report is completely dependent on the quality and availability of data provided by each electric distribution utility. All utility data contained in this report is subject to regular updates and corrections as needed.

Electric consumption data in this report is incomplete due to gaps in data transferred from the following distribution utilities:

Barton Village Electric Department (partial 2019)
Hardwick Electric Department (2017, 2018, 2019)
Village of Hyde Park (partial 2018, 2019)
Ludlow Electric Light Department (partial 2019)
Stowe Electric Department (partial 2019)

All or some towns within these utility service territories may not contain a complete set of annual consumption data for the specified time periods. Efficiency Vermont is working with distribution utilities to obtain the missing data and upload it to our system. Updated versions of the “Annual Usage” summary can be provided periodically upon request as updates occur.

Efficiency Vermont collects savings and cost data associated with a wide range of energy efficiency improvements completed by Vermonters with the help of Efficiency Vermont. Savings, cost and customers served data included in this report is subject to annual verification by the Public Service Department.

Efficiency Vermont is obligated to protect the confidentiality of all Vermont electric ratepayers and the customers it serves. This requires that even aggregated data remains secure. Efficiency Vermont has adopted a standard that ensures customer anonymity and privacy when sharing utility customer and usage data. As such, town sector level results have been excluded from this report if that town has less than 15 customers for one sector.

There are instances where interactive effects of efficiency measures can result in savings of one energy type (kWh or MMBtu) and increase consumption of another type. For example, the installation of a Heat Pump Water Heater in a house that uses propane for space heating, and previously for water heating, would show a positive savings in MMBtu (thermal) due to the decreased use of propane, but this would cause a negative kWh (electric) savings due to the increase in electricity used. In addition, all savings totals, including customer cost and CO2 equivalent emissions reduction, represent only the savings measured by Efficiency Vermont and may not represent the customer-facing full savings of all measures. For example, thermal savings from Cold Climate Heat Pump installations are typically not claimed and therefore not included in the data in this report.

Beginning in 2019, Efficiency Vermont and Distribution Utilities began partnering on service delivery of some measures to customers, as they relate to Tier III of Vermont's Renewable Energy Standard (Act 56); savings and project/measure counts in this report are inclusive of those partnered program activities. However, please note that not all Distributions Utilities are participating and that some may provide additional incentives and claim different savings that noted in this report.

Definitions:

Average Residential Usage - The total residential kWh usage for a year divided by the number of residential premises counted for that year.

Cold Climate Heat Pump Installations - Cold Climate Heat Pump Installations - Includes installations of high efficiency single head and multi-head cold climate heat pumps, air-to-water heat pumps, and centrally ducted heat pumps that meet criteria for efficient heating performance at low temperatures. Does not include other air-source heat pumps that do not meet these criteria, variable refrigerant flow heat pumps, water source heat pumps, or ground-source heat pumps. Note that Efficiency Vermont typically only claims the electric savings associated with the purchase of a more efficient unit; thermal savings typically are not represented in totals for these measures.

Customer Cost Savings - The estimated financial savings for energy (electrical and/or thermal) and water use realized by a customer over the first year that a measure or measures are installed. Customer savings are calculated based on the expected annual electric, fuel, and/or water savings for an efficiency measure, multiplied by the assumed average cost per unit for each. In most cases, assumed statewide average electric, fuel, and water costs are used, but for some custom projects customer-specific costs are used.

Customer Premise - A unique physical location served by the utility. Utilities catalog premises differently therefore the number of premises may not be an accurate representation of the number of residential households or businesses in an area. For example, a household or business can have more than one meter at their location and it's possible for each meter to be considered a unique customer premise by the utility. In addition, farms are sometimes designated as a residential premise.

Customers Served - The number of unique locations where customers have installed at least one energy efficient measure.

Electric Savings (KWH) - The estimated reduction in electricity (kWh) realized by a customer over the first year that a measure or measures are installed. These are distinct from the net savings reported for regulatory purposes, which are adjusted for freeridership, spillover, and other factors.

Heat Pump Hot Water Heater Installations - This is a subset of all hot water measures listed in the Measure Category tables, the number of heat pump domestic hot water installations processed through Efficiency Vermont’s upstream and midstream programs.

Home Energy Visits - A home walk through provided by Efficiency Vermont staff to help residential homeowners prioritize efficiency improvements and answer energy-related questions. Staff spend approximately an hour and a half in the home and at the end deliver a personalized set of recommendations to meet customer energy goals and make their homes more efficient, comfortable, and healthy.

Home Performance with ENERGY STAR® - Sponsored by the Department of Energy, this program connects homeowners with experienced and trusted contractors that can help them understand their home's energy use and identify home improvements that increase energy performance, improve comfort and health, and lower utility bills. The program is cosponsored with Vermont Gas Systems and Burlington Electric Department for homes in their service territories.

Measure - A purchased and installed item or an action that has electrical and/or thermal and/or water savings associated with it.

Other Weatherization Projects - Launched in 2018, Efficiency Vermont offers several programs that help customers install weatherization measures smaller in scope than a comprehensive Home Performance with ENERGY STAR® project. Programs include attic, basement, and do-it-yourself weatherization installations.

Project - A collection of one or more energy efficient measures that have been implemented at a customer's premise (physical location). A customer can be associated with one or more projects and in some cases, a project may be associated with multiple customers.

Residential New Construction Projects - Comprehensive energy efficiency services to customers building new or gut-rehabbing single-family homes. This program maximizes energy efficiency, durability, and comfort through direct technical assistance, third party certification, incentives, and code compliance support. The RNC program is cosponsored with Vermont Gas Systems and Burlington Electric Department for homes in their service territories.

Thermal Savings (MMBTU) - The estimated reduction in heating and process fuel usage (MMBtu) realized by a customer over the first year that a measure or measures are installed. These are distinct from the net savings reported for regulatory purposes, which are adjusted for freeridership, spillover, and other factors.

Total Emission CO2 Equivalent (lbs) - CO2 equivalent emissions reduction based on the fuel and electric savings, multiplied by the carbon dioxide equivalent emissions associated with burning fuel or generating electricity and realized by a customer over the first year that a measure or measures are installed.

Total Lifetime Savings - Distinct from first year savings, lifetime savings represent the expected total savings for an efficiency improvement over the average expected life of the improvement. Different measure types have different measure lifetimes, depending on the measure characterization.

Total Residential Projects - Total of all residential and multifamily project. As per the Project definition above, a customer can be associated with one or more projects and in some cases, a project may be associated with multiple customers. This is not a total count of all residential customers served.

Wood Heating Installations - Includes installations of wood and pellet-fired boilers, furnaces, and stoves used for space heating.
