Nevada has set energy storage targets of 100MW by the end of 2020 and 1,000MW by 2030. They join five other states in adopting specific deployment goals.
The Nevada Public Utilities Commission released a proposal in January, two years after the State’s Legislature solicited a study on the benefits of energy storage. The Commission now requires that electric utilities in the state with gross annual operating revenue of $250 million or more incorporate energy storage into their integrated resource plans. 
From coverage in Energy Storage News:
“Together, Nevada, Massachusetts, California, New York, New Jersey and Oregon have laid out a cumulative target of at least 7,575 MW across the nation by 2030,” US national Energy Storage Association (ESA) CEO Kelly Speakes-Backman said.
“By setting a target of 1,000 MW by 2030 for Nevada, along with interim targets over the coming decade, Nevada officials are sending long-term signals for industry investment and a credible pathway for achievement. ESA applauds Nevada for its leadership and looks forward to supporting the efforts of officials and stakeholders to make the state’s electric system more resilient, efficient, sustainable and affordable”.
Maryland’s own 2018 study completed by the Power Plant Research Program (PPRP) housed within the Department of Natural Resources (DNR) detailed the benefits of energy storage, but also encouraged a strategic approach to incentivization and deployment based around cost-benefit analyses.
From the 2018 study report:
Maryland has the advantage of not being under pressure to address certain problems that storage can help to mitigate, such as constraints on fossil fuel supplies, widespread curtailment of utility-scale wind and solar plants, or significant upward pressure on transmission and distribution costs due to load growth. These circumstances provide Maryland with the luxury to thoughtfully increase storage’s access to the grid, facilitate its participation in electric power markets, and provide compensation for a wider range of the benefits that storage can provide. Such changes will both enable storage to compete with other technologies and address market shortcomings that necessarily result in suboptimal levels of storage investment.
In 2019 Maryland passed the Energy Storage Pilot Project Act that requires four large utilities Potomac Edison, Baltimore Gas and Electric, Delmarva Power, and Potomac Electric Power create two pilot energy storage projects. These projects are set to be online by 2022. Included in the legislation were reporting requirements and a sunset provision.
