For smaller commercial and industrial (C&I) energy storage projects in the 50–500 kWh range, installed costs typically fall in the range of USD $500–$1,000 per kWh.
The average Wellington EK 200kWh system cost ranges between $42,000-$68,000 USD, influenced by these critical factors: "The true value lies not just in upfront costs, but in 10+ years of operational savings," notes a recent industry whitepaper.
All-in BESS projects now cost just $125/kWh as of October 2025 2. With a $65/MWh LCOS, shifting half of daily solar generation overnight adds just $33/MWh to the cost of solar.
The energy storage system is essentially a straightforward plug-and-play system which consists of a lithium LiFePO4 battery pack, a lithium solar charge controller, and an inverter for the voltage requested. Price for 1MWH Storage Bank is $774,800 each plus freight shipping from.
