How much does the energy storage system cost?

The energy storage system is a 4MW, 32MWh NaS battery consisting of 80 modules, each weighing 3 600 kg. The total cost of the battery system was USD 25 million and included USD 10 million for construction of the building to house the batteries (built by Burns & McDonnell) and the new substation at Alamito Creek.

How much does a battery cost on EnergySage?

The median battery cost on EnergySage is $1,037/kWh of stored energy. Incentives can dramatically lower the price of batteries, but the 30% federal tax credit ends after Dec. 31, 2025. You can go off-grid with batteries, but it requires a lot of capacity and money, so most homeowners don't go this route. What exactly are home batteries?

What is a home energy storage system?

A home energy storage system consists of inverters, battery groups, and other energy storage components to create an uninterruptible power supply system for household consumers. This system combines renewable energy and implements load shifting to improve energy quality and bring economic benefits while reducing your electricity bills.

What is energy storage?

The ability to store energy for days, weeks, or months to compensate for a longer-term supply disruption or seasonal variability on the supply and demand sides of the energy system (e.g. storing heat in the summer to use in the winter via underground thermal energy storage systems).

What is the value of energy storage technologies?

The value of energy storage technologies lies in the services that they provide at different locations in the energy system, including heat to heat, electricity to electricity, electricity to heat, and heat to electricity applications. This roadmap therefore includes discussion of storage technologies in the context of these applications.

How much does a home backup battery cost?

Home backup batteries store electricity for later use and can be used with or without solar panels. The median battery cost on EnergySage is $1,037/kWh of stored energy. Incentives can dramatically lower the price of batteries, but the 30% federal tax credit ends after Dec. 31, 2025.
