Unlike residential energy storage systems, whose technical specifications are expressed in kilowatts, utility-scale battery storage is measured in megawatts (1 megawatt = 1,000 kilowatts).
In a BESS, the MWh rating typically refers to the total amount of energy that the system can store. For instance, a BESS rated at 20 MWh can deliver 1 MW of power continuously for 20 hours, or 2 MW of power for 10 hours, and so on.
Developers building intermittent renewable energy plants in the Philippines with 10 MW or greater capacity will need to install energy storage systems (ESS) alongside under new rules issued by the Department of Energy.
They must use electricity supplied by separate electricity generators or from an electric power grid to charge the storage system, which makes ESSs secondary generation sources.
NFPA 855 is the flagship fire-protection code for stationary energy storage systems (ESS), covering everything from coin-cell pilot rigs to multi-megawatt battery energy storage systems (BESS). Its scope spans siting, construction, ventilation, detection, suppression, and emergency.
As of most recent estimates, the cost of a BESS by MW is between $200,000 and $420,000, varying by location, system size, and market conditions. This translates to around $150 - $420 per kWh, though in some markets, prices have dropped as low as $120 - $140 per kWh.

Since February 2025, when the National Development and Reform Commission (NDRC) and the National Energy Administration issued the "Notice on Deepening the Market-oriented Reform of New Energy Feed-in Tariffs to Promote High-quality Development of New Energy," explicitly.
The project is part of the inaugural Malaysia Battery Energy Storage System (MyBeST) program, a competitive bidding initiative representing the largest deployment of grid-connected BESS in Peninsular Malaysia to date.
