Taiwan’s ProPower Eyes Poland as European Battery Storage Market Accelerates
Taiwanese energy storage integrator ProPower is evaluating Poland as a potential gateway into the European market as the country rapidly expands battery energy storage capacity. Poland's transition away from coal, growing renewable generation and increasing need for grid flexibility are creating a substantial pipeline of BESS projects. Industry forecasts suggest utility-scale battery capacity could reach 8–9 GW by 2030. However, constrained grid connections and a shift away from capacity-market-backed revenues mean new entrants will need more than battery hardware to succeed.
U.S. Energy Storage Capacity Surges 29-Fold in Six Years as California Sets Record for Daily Battery Power Supply
U.S. energy storage capacity has skyrocketed from 6,000 MWh in 2020 to 175,000 MWh in 2026, enough to power 5 million homes for a day. On August 1, California’s battery storage systems delivered a record 13,000 MW, accounting for one-third of the state’s total electricity demand, underscoring the critical role of energy storage in grid management. Five states are leading the charge with policies aimed at enhancing grid stability and reducing electricity costs.
Energy Management Law Amendment Drives Enterprise Energy Storage Opportunities, Star Power Targets 360MW by Year-End
Amendments to the Energy Management Law require enterprises with newly installed or expanded power equipment above a certain capacity to equip energy storage or self-use power generation systems. Star Power plans to expand its capacity to 360MW by the end of this year through the ETF5050 behind-the-meter energy storage sharing program, advancing power trading and green electricity transfer services.
Energy Management Act Amendment Mandates Energy Storage or Self-Generation for Large Users
The Legislative Yuan passed amendments to the Energy Management Act, requiring newly established or expanded large energy users to install either self-generation or energy storage equipment. Violators face fines of up to NT$750,000. The Ministry of Economic Affairs stated this measure will enhance corporate energy autonomy, alleviate grid pressure, and address rising electricity demand from AI and electronics industries.
Taiwan Offers NT$5 Million Subsidy per MWh for Domestic Battery Cell Energy Storage Deployment
On August 18, the Ministry of Economic Affairs announced a subsidy of NT$5 million per MWh for behind-the-meter energy storage systems using domestically produced lithium-based battery cells. The initiative aims to accelerate the adoption of energy storage in industrial parks and science parks while boosting the domestic battery cell supply chain. The Bureau of Energy stated this will improve power quality and guide industries toward energy storage models.
Bill Gates-Backed TerraPower to Launch Data Center-Specific Nuclear Plant in 2027, Meta Signs Deal for Up to 8 Natrium Reactors
