Recently, China Classification Society Quality Certification Co., Ltd. (CCSC) successfully passed the expanded evaluation of the qualification of inspection and testing institutions (CMA) organized by the National Certification and Accreditation Supervision and Administration Committee, and formally obtained the qualification of electrochemical energy storage power station access to the power grid. The approval of this qualification marks a major leap in the companys service capabilities in the field of new energy testing, and injects strong third-party technical support for the high-quality development of the energy storage industry.
The approved CMA qualification is tested for electrochemical energy storage power stations, with a total of 15 authorized testing items, covering all-factor requirements for access to grid performance testing. The qualification is based on the two latest national standards GB/T 36547-2024 "Technical Regulations for Connecting Electrochemical Energy Storage Power Stations to Power Grids" and GB/T 36548-2024 "Test Regulations for Connecting Electrochemical Energy Storage Power Stations to Power Grids". Specific detection capabilities include power control-active power control, reactive power control, power factor adjustment capability; Energy and timing-charge and discharge time, rated energy efficiency, rated energy; Power quality-power quality (harmonic, flicker, three-phase imbalance, etc.); Power grid support-primary frequency regulation, inertia response, operation adaptability; Fault safety-fault ride through (low voltage/high voltage ride through); limit capacity category-overload capacity, emergency power support; Automatic control category-automatic generation control (AGC), automatic voltage control (AVC), covering the electrochemical energy storage power station from the commissioning of the grid to the operation monitoring of the whole life cycle of the key links, can provide customers with one-stop, full chain of access to the grid detection technology services.
In recent years, with the acceleration of the construction of new power system in China, the installed scale of electrochemical energy storage power station continues to rise. The National Energy Administrations Notice on Strengthening the Safety Management of Electrochemical Energy Storage Power Stations (Guoneng Comprehensive Safety [2022] No. 37) clearly stipulates: "Electrochemical energy storage power stations to carry out grid-connected testing must be entrusted to a third-party organization with professional testing and inspection qualifications for energy storage. Before grid-connected acceptance, key tasks such as type tests of main equipment and systems of the power station, commissioning tests of the whole station and grid-connected testing must be completed." With the intensive introduction of new energy storage policies around the world, the grid-connected testing of energy storage power stations has changed from "optional" to "mandatory". CMA-qualified third-party testing institutions have become the key technical support for energy storage projects to be connected to the grid and obtain grid access permits. At the same time, the companys five core advantages, cast the testing hard core strength: First, the standard lead, qualification according to the latest version of the 2024 national standard, technical capabilities and national grid-connected requirements synchronous update, to ensure the authority and effectiveness of the test results. Second, the equipment is complete, equipped with data acquisition instrument, power quality analyzer, power grid simulation device and other precision testing equipment, to meet the large-capacity energy storage power station project testing needs. Third, the team is professional. The testing team covers electrical engineering, power system, new energy science and other multidisciplinary backgrounds. The core members have rich on-site testing experience. Fourth, the network coverage, relying on the companys national 32 branch service network, can quickly respond to the needs of energy storage project testing, to provide efficient services nearby. Fifth, the qualification is complete, in addition to CMA testing qualification, the company also holds the National Energy Administration issued by the installation (repair, test) power facilities license level 3 qualification, can provide energy storage projects from testing to construction commissioning of the whole chain of services.
The acquisition of CMA qualification is an important milestone in the companys new energy testing business layout. As a result, the company has the legal qualification of electrochemical energy storage power station access to the power grid testing, the comprehensive service system in the new energy field is more complete, and the business coverage and service depth are improved simultaneously. Facing the future, the company will continue to focus on new energy storage, offshore wind power, photovoltaic grid, electric ships and other new energy frontier fields, and continuously improve the detection technology capabilities and service levels, for Chinas energy green low-carbon transformation and "double carbon" goal to contribute professional strength.
