The increasing adoption of renewable energy projects is expected to propel the growth of the battery energy storage engineering, procurement, and construction (EPC) market going forward. Renewable energy projects are initiatives focused on developing and deploying energy generation systems using renewable sources such as solar, wind, hydro, biomass, and geothermal to produce sustainable electricity or heat. The adoption of renewable energy projects is growing due to cost competitiveness, as falling technology and installation costs make renewable energy more affordable than conventional fossil-fuel-based sources. Battery energy storage EPC solutions support renewable energy integration by enabling energy storage, managing intermittency, ensuring grid stability, and maintaining reliable power supply across electricity networks. For example, in March 2025, according to the International Renewable Energy Agency (IRENA), a UAE-based intergovernmental organization, renewable power capacity additions reached 585 GW in 2024, accounting for 92.5% of total net power capacity. Therefore, the increasing adoption of renewable energy projects is driving the growth of the battery energy storage EPC market.

Companies operating in the battery energy storage engineering, procurement, and construction (EPC) market are focusing on developing high-efficiency utility-scale inverters, to improve energy conversion efficiency, reduce project costs, and support faster deployment of battery energy storage systems. High-efficiency utility-scale inverters refer to power conversion technologies that manage energy flow between batteries and the grid, optimize system performance, and integrate with large-scale storage solutions used by EPC providers. For example, in May 2025, GE Vernova Inc., a US-based industrial energy company, introduced the FLEXINVERTER platform, a next-generation inverter solution specifically developed for utility-scale battery energy storage systems. The platform is engineered to improve EPC project efficiency and system performance by integrating advanced silicon carbide (SiC) power electronics, which significantly enhance electrical efficiency and thermal performance. Its high power density design reduces equipment footprint, enabling more flexible plant layouts and optimized balance-of-plant requirements. In addition, the compact and modular architecture simplifies transportation, installation, and commissioning, reducing construction timelines and labor intensity. Collectively, these features help lower capital and operating costs while improving system reliability, supporting the cost-effective deployment of large-scale battery energy storage projects.

In June 2024, Generac Power Systems Inc., a US-based energy solutions company, acquired Powerplay Battery Energy Storage Systems, a division of SunGrid Solutions Inc., for an undisclosed amount. Through this acquisition, Generac aims to broaden its product and solutions ecosystem for residential, commercial, and industrial customers by incorporating PowerPlay’s turnkey battery energy storage systems, enhancing its capacity to deliver resilient, efficient, and sustainable on-site energy solutions. Powerplay Battery Energy Storage Systems is a US-based company providing engineering, procurement, and construction (EPC) services for battery energy storage systems.
