MI Energy Efficiency Resource Standard

Energy Waste Reduction Targets

AI summary · 7/12/2026

Michigan utilities must reduce electricity use by 1.5% annually and natural gas use by 0.875% annually through energy optimization plans submitted by January 1, 2025. Residential customers will see these costs recovered through volumetric charges on gas bills and per-meter charges on electric bills. Low-income programs receive at least 25% of utility spending on energy waste reduction.

Utilities are the primary program administrators and must file energy optimization plans that include energy waste reduction strategies and may include efficient electrification measures; commercial and industrial customers with certain peak demand levels may opt out of surcharges and implement self-directed plans instead. Program cost-effectiveness is evaluated using the Utility Cost Test (UCT) as the primary metric from the California Standard Practice Manual.

Public Act 229 (2023) sets mandatory annual energy savings targets—1.5% for electric utilities and 0.875% for natural gas utilities—with the Michigan Public Service Commission (MPSC) overseeing compliance and recovery of implementation costs through customer surcharges. Utilities exceeding standards may receive additional financial incentives from the MPSC, and the program includes a mandatory low-income component funded at minimum 25% of total energy waste reduction spending.

Program summary

Public Act 229 of 2023, known as the Clean and Renewable Energy and Energy Waste Reduction Act, amends Michigan’s 2008 energy law, Act 295. This new legislation sets revised Energy Waste Reduction targets for electric and natural gas providers and requires the filing of Energy Optimization Plans. These plans must include strategies for Energy Waste Reduction and may also include optional measures for Efficient Electrification.

Under the Act, electric utilities are required to achieve annual energy savings of 1.5% of their total retail sales from the previous year, while natural gas utilities must achieve annual savings of 0.875%. Utilities were required to submit customer energy optimization plans including energy waste reduction plans by January 1, 2025.

History

In October 2008, Michigan enacted the Clean, Renewable, and Efficient Energy Act, Public Act 295, requiring the state's investor-owned utilities, alternative retail suppliers, electric cooperatives and municipal electric utilities to generate 10% of their retail electricity sales from renewable energy resources by 2015. This is known as the Renewable Energy Standard (RES). In addition, the standard requires both electric and natural gas utilities meet certain energy savings requirements, known as the Energy Optimization Standard (EOS).

For both the electric and gas requirements, the Michigan Public Service Commission (MPSC) must submit an annual report to the legislature, describing the MPSC's efforts to implement energy conservation and energy efficiency programs and measures. The most recent reports were published in November 2014 and September 2015.

Electric Sales Reduction

The Clean and Renewable Energy and Energy Waste Reduction Act requires electric utilities to reduce their annual energy sales by 1.5% each year.

Natural Gas Sales Reduction

The Clean and Renewable Energy and Energy Waste Reduction Act requires natural gas utilities to reduce their annual energy sales by 0.875% each year.

The cost of implementing approved energy optimization plans is recovered from natural gas customers by volumetric charges.

Program Administrator Type

The utilities required to meet these standards administer the programs required to meet the EOS.

Cost Effectiveness and Program Evaluation

While Michigan uses all five of the "California tests" of utility program cost effectiveness from the California Standard Practice Manual to evaluate EOS programs, it uses the Utility Cost Test (UCT) as its primary test.

Utility Cost Recovery Provisions

The cost of implementing an approved energy optimization plan is recovered from volumetric charges on all natural gas customers and residential electric customers, per-meter charges on all other metered electric customers, and itemized charges on unmetered electric customers.

For utilities that exceed the standards set forth, the MPSC may authorize additional financial incentives for the utility.

Special Provisions

Commercial and industrial electric customers may opt out of the surcharge and implement a self-directed energy optimization plan. In order to participate in this program, the customer must meet certain annual peak demand requirements. Forms and filing instructions are available on the MPSC website. Self-directed customers may not opt out of surcharges required for low income programs.

Utilities are required to offer low income energy waste reduction programs that use at least 25% of the utility's total spending on their energy waste reduction plan.
