Kehua Tech has announced that its PCS (power conversion systems) and MV Stations equipment already meet the technical requirements of the LRCAP (Capacity Reserve Auction) for energy storage projects in Brazil.
According to the company, in addition to the official documents guaranteeing the conformity of the equipment, the documentation relating to the mathematical models is also in an advanced stage.
The requirements are outlined in Technical Note NT-ONS DPL 0114/2025, which establishes new mandatory parameters for BESS (Battery Energy Storage System) systems.
In this context, the company believes that the choice of PCS and MV Stations is no longer just an engineering decision, but has a direct impact on the viability of the projects in the auction.
Grid-forming: a non-negotiable requirement for qualification.
According to the corporation, its skids operate with behavioral patterns. grid-forming, acting as an autonomous voltage source, including in islanding situations and in scenarios of disturbances in the electrical system.
The corporation not only claims this, but also has evidence in its portfolio of projects where the equipment is capable of supplying active and reactive power and also contributing to the damping of oscillations, in line with the technical parameters defined by the ONS (National System Operator).
Another key point highlighted is the ultra-fast response of the systems, operating in milliseconds, a characteristic considered essential for the reliability of the BESS connection to the SIN (National Interconnected System).
Also according to Kehua TechPCS systems can withstand temporary overcurrents, being able to operate at up to 150% of the nominal current for a period of up to five seconds. And in some specific projects, they can go even further (as is the case with the 300MW/1,2GWh project supplied by Kehua in Northwest China, which reaches 300% overload for 10 seconds).
The company explained that they meet the requirements for active and reactive power response, reaching 90% of the first peak within one cycle of the fundamental frequency (1/60 of a second).
At the plant level, the company justifies that its solutions meet the operational compliance criteria required by the ONS (National System Operator), such as dynamic and continuous control, minimum operating capacity (PQ), voltage control, and frequency control with adjustable standoff between 2% and 8%.
Within the scope of the technical studies required for certification, the company clarifies that it is responsible for the development and validation of the mathematical models used in the analysis of electromechanical and electromagnetic transients.
These models are used in tools such as ANATEM and PSCAD and undergo testing in a C-HIL (hardware-in-the-loop) environment, according to the system operator's requirements.
The skids also integrate the necessary infrastructure for sending operational information to the ONS in real time, with intervals between four and six seconds.
National market
Recognized by CNESA (China Energy Storage Alliance) in 2025 as the largest supplier of PCS in the Chinese domestic market and by S&P Global as the number 1 PCS manufacturer in the world, Kehua Tech claims to combine scale, technological maturity and competitiveness in storage solutions.
In the Brazilian context, the company highlights its participation in the largest energy storage project currently in operation in the country, by ISA Energia, with 33,5 MW of power and 67 MWh of capacity, where the PSCAD/ANATEM documents for the supplied PCS/MV stations went through the approval, transcription, and validation process by ONS.
For the LRCAP 2026, the company reported that it has a modular portfolio of central power plants, with capacities ranging from 1 MW to 1,725 MW, as well as skids and MV stations in 20- and 40-foot containers, with configurations that can reach up to 10 MW per unit.
According to the company, the solutions allow for different capacity arrangements, depending on the technical and economic strategy of each project.
Finally, the company stated that it is supporting developers and companies that are structuring projects for the 2026 capacity auction, sharing expertise and providing the BESS AC solution.
“Kehua Tech is interested in supporting, from now on, companies that are structuring projects for LRCAP 2026, focusing on discussions and technical support for their clients. Therefore, it extends the invitation to its engineering and management team for a detailed analysis of the portfolio of PCS and Skids available in Brazil,” the company highlighted.
