Energy Efficiency Standards
The Next Generation Energy Act of 2007 amended existing energy conservation law to create an energy efficiency portfolio standard in Minnesota. The statutory requirements for energy efficiency savings (referred to as "conservation improvements") are found in Minn. Stat. 216B.241.
Minnesota has an annual savings goal of 1.5% of average annual retail sales for all utilities and associations (both electric and gas). The commissioner can modify this goal (based on a potential study or other factor), but cannot approve a goal below 1.0% for investor-owned utilities. The Act also requires minimum spending levels equal to 1.5% of annual gross operating revenues (GOR) for electric utilities and 0.5% of annual GOR for gas utilities. Utilities are also required to invest a minimum of 0.2% of residential GOR on low-income programs.
Currently, investor-owned utilities file triennial Conservation Improvement Program(CIP) plans and annual status reports on their CIP performance and compliance from the past year. Cooperatives and municipal utilities submit annual plan updates and status reports.
Minnesota requires utilities to file integrated resource plans (IRPs) with the Public Utilities Commission that consider all resources to meet future energy needs including "refurbishing, and constructing utility plant and equipment, buying power generated by other entities, controlling customer loads and implementing customer energy conservation." Plans are filed biennially and must include a 15-year forecast of future energy needs.
Utilities filing a Certificate of Need application seeking to expand generation or transmission capacity must also include the most recent IRP and information about their energy efficiency activities.
Rate Structures & Incentives
Utilities can file rate schedules to recover the cost of conservation improvement programs. In its determination of just and reasonable rates, the commission is required to consider investment and expenses incurred in conservation improvement program implementation.
Lost Revenue Recovery
The PUC reviewed criteria and standards for decoupling in Docket Number 08-132, and filed an Order Establishing Criteria and Standards to be used in Pilot Proposals for Revenue Decoupling (Document ID: 20096-38723-01). (Note Minnesota PUC docket system does not allow permanent hotlinks, please search by docket number or document ID at their edockets search page)
The commission is authorized to adjust utility incentives to reward progress toward meeting conservation improvement targets. Currently, all investor-owned utilities in Minnesota are operating under a shared savings model that awards utilities with an increasing percentage of net benefits as higher savings are achieved. The current form of the incentive was approved in early 2010, with an update in 2012 to slightly reduce incentives for electric utilities and increase the incentives for natural gas utilities.
Utilities can file proposed methods for incentivizing conservation improvement performance. Incentives can include an increased rate of return, a shared savings model or other methodology approved by the commission that is consistent with implementing energy efficiency as a preferred, cost-effective energy resource.
There are no direct monetary penalties for noncompliance with Conservation Improvement Plans, though a loss of performance incentives associated with achieving CIP targets would apply some economic pressure toward compliance. Additionally, a utility could be denied a Certificate of Need for the construction of a new facility if they do not demonstrate that they are meeting their CIP requirements.
The Department of Commerce initiates stakeholder collaboratives on such topics as calculating avoided costs of energy and improving the technical reference manual on both an as-needed and on-going basis.
Utility conservation improvement plans must be cost-effective at the program level "from the utility, ratepayer, participant and societal perspectives." Accordingly, the following cost-effectiveness tests are required: the Program Administrator Cost Test (PACT), the Ratepayer Impact Measure (RIM), the Participant Cost Test (PCT) and the Societal Cost Test (SCT).
Net vs. Gross
Minnesota requires only gross energy savings to be reported. Annual reports must include actual energy savings, but there is no requirement for adjusting for free-ridership or spillover.
Technical Reference Manual
The Department of Commerce, Division of Energy Resources maintains the Technical Resource Manual for the Minnesota Conservation Improvement Programs. The Technical Reference Manual includes the deemed savings database of approved specifications for energy efficiency measures that utilities would include in their CIP plans. The deemed savings are reviewed and updated periodically to include new technologies or revised savings levels.
State Energy Plan or Vision
Minnesota has a long history of supporting energy efficiency. Through legislation, regulations and executive orders and various other strong energy policies, Minnesota has remained near the top of national energy efficiency rankings for a number of years. There is not a single broad non-legislative policy document that lays out a statewide energy policy vision, but Minnesota is one of the Midwest leaders in its energy efficiency practices.
State Agency Energy Reduction Requirement
Minnesota set a goal of reducing energy use in state facilities by 20%. The order does not set a deadline for reaching this goal, but sets deadlines for establishing benchmarks, goals and implementation plans. Each agency must maintain its consumption data in the B3 Energy Benchmarking tool.
Each agency is required to report on these goals in an annual Sustainability Plan. Each state agency must use the Guaranteed Energy Savings Contracts and State Energy Improvement Financing Program to implement cost-effective energy improvements.
EE in New State Buildings
In 2001, Minnesota adopted Sustainable Building Guidelines, requiring the Departments of Administration and Commerce to develop the Minnesota Sustainable Building Guidelines for new state buildings. As amended in 2008, new buildings and major renovations must achieve initial energy savings 30% above the state's building energy code.
Additional clean energy measures require that building managers must supply 2% of a building's total energy use with on-site wind and solar power.
In 2009, the Public Buildings Enhanced Energy Efficiency Program was launched in order to provide assistance to state and local government buildings for recommissioning and retrofit projects.
