According to the Energy Storage Association (ESA), it is possible to have 100 gigawatts of new energy storage deployed in the United States by the end of the decade.
The national trade association whose members include independent power producers, electric utilities, energy service companies, installers, manufacturers and others, outlined the opportunities for this growth in “100x30: Enabling the Clean Power Transformation.”
“The ongoing transformation of the grid from fossil fuels to renewable generation will continue regardless of any headwinds encountered from current policy or economic downturns, and the deployment of energy storage systems will accelerate,” states the white paper.
“Energy storage applications and uses are multiplying, including integration of variable renewable generation, reducing renewable generation curtailments, enhancing reliability and resilience, deferring costly transmission and distribution grid expansion and upgrading, increasing customer control over energy consumption, enabling significant local penetration of electric vehicle charging, and many more uses.”
While lithium-ion batteries currently dominate the market for energy storage, the future holds significant potential for contributions from other battery technologies, including flow batteries, thermal storage, mechanical storage and pumped storage hydro.
“Rapidly increasing investment will occur as markets respond to the increased cost-effectiveness of energy storage technologies, and as supportive legislative and regulatory policies play an important role in setting the pace of grid transformation,” the organization noted in the report.
The paper also included a number of recommendations to facilitate this growth.
Legislators were encouraged to conduct energy storage impact studies, enact deployment targets, establish incentive programs and set clean energy standards.
For regulators, the recommendation was to establish clear rules for storage, use updated modeling in proceedings and streamline interconnection standards.
Finally, utilities should expand integrated resource planning to include storage and exploring new ownership and business models, according to the paper.
