Michigan’s newly enacted energy storage target means we now have 10 states in the club. On April 21, 2022, Governor Gretchen Witmer released the MI Healthy Climate Plan, a roadmap for Michigan to achieve economy-wide carbon neutrality by 2050 with interim 2030 goals. In addition to recommendations for renewable energy, the plan established a target of 4,000 MW of energy storage by 2040.
Fractal speculated that Michigan would be next. The state recently published a study (March 2022) that recommended energy storage targets. The report said that the state of Michigan would need to deploy 2,500 MW of energy storage by 2030 and 4,000 MW by 2040 to ensure grid reliability as fossil fuel generation retires. To facilitate that goal, the report recommended a “value of storage” study that could quantify the contributions storage makes to the grid, an economic gap analysis to set grant and rebate levels for customers and upgrades to building codes to include storage readiness requirements. The report also recommended new legislation requiring utility integrated resource plans (IRPs) to evaluate storage opportunities and to establish on-bill financing pilot programs for residential and commercial projects.
- Assembly Bill (A.B.) 2514 (2013) directed the state’s three investor-owned utilities (IOUs) to procure 1,325 MW of storage by 2020 with installations operational by 2024 (580 MW from SCE, 580 MW from PG&E, 165 MW from SDG&E).
- A.B. 2868 (2016) directed the same utilities to add an additional 500 MW of additional storage to be rate-based. No more than 25 percent of the capacity could be behind-the-meter (BTM).
- S.B. 801 (2018) required SCE to deploy 20 MW energy storage to meet energy reliability requirements in the greater Los Angeles area associated with the Aliso Canyon gas explosion.
- CPUC Rulemaking 20-05-003 (Feb 2022) requires utilities to add an additional 15,000 MW of energy storage, emphasis on long duration, and demand response by 2032
Let’s look at the other states with storage targets:
- S.B. 952 (2021) set a target of 1 GW of energy storage to be achieved by 2030. Sets interim targets of 300 MW by 2024 and 650 MW by 2027.
- LD 528 (2021) set a 400 MW energy storage target to be achieved by 2025, and 500 MW by 2030.
- House Bill (H.B.) 4857 (2018) established a 1,000 MWh energy storage deployment target to be achieved by 2026.
- S.B. 204 (2017) directed the Public Utilities Commission of Nevada to establish biennial targets for NV Energy Inc.’s procurement of energy storage systems, starting at 100 MW by the end of 2020 and increasing to 1,000 MW by the end of 2030.
- A.B. 3723 (2018) set targets of 600 MW of energy storage capacity within three years and 2 GW of capacity by 2030.
- S.B. 5190 and A.B. 6571 directed the New York Public Service Commission (PSC) to develop an Energy Storage Deployment Program, including 3,000 MW by 2030 with an interim goal of 1,500 MW by 2025.
- H.B. 2193 (2016) required Portland General Electric (PGE) and PacifiCorp to each have a minimum of 5 MWh of energy storage in service by January 2020.
- H.B. 1526 and S.B. 851 (2020) and 20 VAC 5-3535, had Virginia Governor Ralph Northam signed the Virginia Clean Economy Act (VCEA) mandating a 3.1 GW energy target and a goal to achieve 100% renewable and clean energy by 2050.
Who will be next? Well, Maryland, New Hampshire, Rhode Island and Minnesota have favorable climates that include storage deployments, state policy and incentives, that could lead to storage targets.
