Minnesota’s Next Decade of Energy Efficiency Potential
February 13, 2019

Background on Study
Long history of “CIP” (Conservation Improvement Programs)
4
1989: All Public utilities were required to
operate conservation improvement programs. Oversight transferred from PUC, low-income requirements added.
1983: Utilities with revenues
greater than $50 million were required to operate at least 1 conservation program. Required “significant” investment.
1991: A specific level of spending was required (1.5% electric, 0.5% gas) & munis and
coops were included.
2007: Next Generation Energy Act Passes.
2010: 1.5% Savings Goal for Utilities takes Effect
2017: Municipal and cooperative utilities meeting a specific threshold exempted from CIP.
1980: PUC directed to initiate a pilot to demonstrate the “feasibility” of investments in EE.

Program
• Maximum Achievable: Subset that is achievable considering market barriers, given the aggressive incentives and idealized programs • Rebates set at 100% • Technology adoption at theoretical
maximum
• Program Potential: Subset of achievable, given constrained incentives (50%) and program budgets

Results – Emissions Reduction from Electric Potential
2029 cumulative annual program potential
• Emissions reduction: 5,528,600 tons CO2e
• Equivalent to the annual emissions of
approximately one-third of Minnesota’s
1.6 million single family homes
Results – Emissions Reductions from Natural Gas Potential
2029 cumulative annual program potential
• Emissions reduction: 2,763,400 tons CO2e
• Equivalent to the annual emissions of
approximately one-sixth of Minnesota’s
1.6 million single-family homes

From an overall societal perspective, the program scenario results in $2.20 of benefits for every dollar spent
From the utility’s perspective, the program scenario also results in $2.20 of benefits for every utility dollar spent
Program Findings and Recommendations
Current MN Utility Program Findings
Minnesota has a strong foundation of effective CIP programs
•Minnesota currently has some of the lowest cost and best performing programs in the country
• Utilities in Minnesota – both IOUs and COUs – have been proactive in designing and implementing comprehensive, effective, and innovative program models
Partnerships have helped increase program effectiveness
• Deep relationships with trade allies have helped utilities deliver programs
• Smaller utilities face additional challenges in implementing programs, but the most successful COU programs involve cooperation among utilities
• Some utilities have achieved enhanced performance through joint natural gas-electric programs 31
Electric utilities will need to increase diversity of end-uses addressed by CIP programs

Program Recommendations
Recommendations for Utility Programs:
• Continue to test promising new approaches.
• Offer comprehensive program designs for larger and harder-to-reach customers.
• Develop upstream incentives and associated program support in selected markets.
• Incorporate operational savings into commercial and industrial programs.
• Employ segment-specific strategies to reach customers.
• Deepen trade ally engagement and training efforts.
• Incorporate AMI-enabled capabilities into programmatic strategies.
• Leverage interest by local governments in energy efficiency.
Coordination among Utilities:
• More systematically share best practices and program successes.
• Coordinate more closely on trade ally outreach and training.
• Work further towards coordinated and/or joint implementation of programs.

1.5% Savings Goal Statute
•The 1.5% savings goal can continue to be achieved using the existing flexibility to adjust goals when justified.
•Consider allowing consumer-owned utilities to report savings in a multi-year framework.
42
Regulatory Oversight of CIP
•Creation of CIP guide
•Consider formal advisory committee for CIP regulatory topics
•Continue to have strong research and development to support future savings
43
Incorporating Demand Response & Efficient Fuel-Switching Into CIP
could provide significant co-benefits to end-use efficiency
44
Demand Response
Efficient Fuel Switching
could open up new sources of energy efficiency
Any new policies should include safeguards to ensure that end-use efficiency is not decreased
