Base Power has secured a $1 billion Series D funding round, valuing the company at $13 billion post-money, less than a year after its previous billion-dollar raise. This follow-on round will accelerate production of their new Base Core home battery, which stores 39.2 kWh, and aims to double their current installation rate of approximately 100 batteries per day. The company, operating in Texas and Illinois, has already deployed over 500 megawatt-hours of storage and offers batteries on a subscription basis.
