The 246 MW Cebu Energy power station consists of 3 x 82MW coal-fired generators. Units 1 & 2 began operating in 2010, and Unit 3 began operating in 2011. The station is operated by Cebu Energy Development Corporation. The project was estimated to cost P23 billion (approximately 500 million USD).
Larger facilities with higher energy demands will require more extensive and costly systems. Battery energy storage systems using lithium-ion technology have an average price of US$393 per kWh to US$581 per kWh. While production costs of lithium-ion batteries are decreasing, the upfront capital costs can be substantial for commercial applications.
Battery Energy Storage Systems, commonly known as BESS, are advanced energy storage solutions designed to store electricity generated during periods of low demand or from renewable sources such as solar panels or wind turbines.

In 2025, the typical cost of commercial lithium battery energy storage systems, including the battery, battery management system (BMS), inverter (PCS), and installation, ranges from $280 to $580 per kWh. Larger systems (100 kWh or more) can cost between $180 to $300 per kWh. How does battery chemistry affect the cost of energy storage systems?
Energy storage system costs for four-hour duration systems exceed $300/kWh for the first time since 2017. Rising raw material prices, particularly for lithium and nickel, contribute to increased energy storage costs. Fixed operation and maintenance costs for battery systems are estimated at 2.5% of capital costs.
In 2025, the typical cost of a commercial lithium battery energy storage system, which includes the battery, battery management system (BMS), inverter (PCS), and installation, is in the following range: $280 - $580 per kWh (installed cost), though of course this will vary from region to region depending on economic levels.
As we look ahead to 2024, energy storage system (ESS) costs are expected to undergo significant changes. Currently, the average cost remains above $300/kWh for four-hour duration systems, primarily due to rising raw material prices since 2017.
Brand reputation significantly influences the price of a 10kW solar battery. Some of the leading brands include: Tesla Powerwall: Generally priced between $10,500 and $12,500, this battery offers robust performance and great efficiency. LG Chem Resu: Prices typically range from $9,000 to $10,500, known for high energy density and reliability.
Lithium-Ion: Known for high energy density and long lifespan. Typically costs between $10,000 and $15,000 for a 10kW system. Lead-Acid: Cheaper but less efficient. Prices generally range from $8,000 to $12,000. Lifespan and performance often suffer compared to lithium-ion options.
Looking at 100 MW systems, at a 2-hour duration, gravity-based energy storage is estimated to be over $1,100/kWh but drops to approximately $200/kWh at 100 hours. Li-ion LFP offers the lowest installed cost ($/kWh) for battery systems across many of the power capacity and energy duration combinations.
Non-battery systems, on the other hand, range considerably more depending on duration. Looking at 100 MW systems, at a 2-hour duration, gravity-based energy storage is estimated to be over $1,100/kWh but drops to approximately $200/kWh at 100 hours.
