Recently, three more products from TWS Technology — the Max-Classic C&I Energy Storage Cabinet, the PowerMod Container, and the PowerCore Container — have successfully obtained listing certification from the California Energy Commission (CEC). This achievement signifies that the three products fully comply with the stringent energy efficiency standards of the US market. This not only opens a crucial channel for TWS Technology to fully enter the mainstream North American energy storage market but also allows partners to unlock core subsidy applications, such as the California SGIP, leveraging policy benefits to optimize costs and drive industry technology upgrades and open win-win partnerships.
The CEC Listing is an authoritative access certification introduced by the California Energy Commission (CEC) of the United States. Its core purpose is to target various terminal equipment, such as energy storage products, and set high standards for the products’ energy efficiency and environmental protection indicators.
— It is a mandatory requirement for legal entry into the California market.
— It is the core “pass” to open the door to the entire North American market.
The smooth passage of the three energy storage products of TWS Technology with the CEC Listing legally covers the high-end market across North America, offering energy efficiency backed by official environmental credentials. This assists partners in securing government projects and large-scale energy storage orders, enhancing their differentiated market competitiveness. It aligns with low-carbon policies, reducing long-term operating costs for users, and enabling the acquisition of additional revenue through the SGIP subsidy policy, thereby enhancing project return on investment.
The successful CEC listing of these three products is an important milestone in TWS Technology’s strategic plan to further penetrate the North American energy storage market.
