To guide project development, the decree includes reference examples of potential storage needs across seven regions, totaling approximately 935MW of 3-hour duration systems:

However, the government emphasised these figures are illustrative rather than restrictive. “The following table serves as a reference for identifying electrical energy storage needs,” the decree states, “but it does not constitute a strict limit for the submission of proposals.”
A technical analysis group will evaluate projects based on multiple criteria, including grid reliability improvements, congestion relief, operational flexibility, socio-environmental contributions, and economic efficiency.
Projects offering the greatest benefits to the National Electric System will receive priority when multiple proposals compete for the same grid connection points.
