The Berlin GreenCHARTSTAUP PLAN-B NET ZERO BESS GmbHDaughter of the PLAN-B NET ZERO AG And specializing in innovative energy storage solutions, shows how its battery energy storage systems (BESS) enable companies and private households to benefit directly from the increasing imbalance between very low and very high prices on the electricity exchange (EEX).
Intelligent battery memory transform negative power prices to profit
In 2025, negative electricity prices are no longer an exceptional phenomenon, but a central feature of the energy transition. What is a burden for the power grid is for customers of PLAN-B NET ZERO to the source of income.
Germany’s accelerated expansion of renewable energies has produced a paradox: on sunny and wind -rich days, dishes are more electricity into the network than is required. This oversupply presses the wholesale prices more and more under zero – producers even have to make their performance against payment. In the second quarter of 2025 alone, over 345 hours were recorded with negative prices, including a record low of -250.32 euros per MWh at the EEX.
This is exactly where PLAN-B NET ZERO AN: The company’s BESS systems are equipped with intelligent measurement and control units that communicate with the network in real time. As soon as the prices become negative, the memory automatically charges – customers are paid for absorbing energy. The stored energy is submitted when the prices are high again or your own needs increase. This principle of energy arbitrage creates new, stable sources of revenue.
Based on extensive modeling PLAN-B NET ZEROthat a typical BESS for prosumers and businesses pay for itself in less than five years. After that, the system not only generates constant additional revenues, but also offers energy independence and a reliable emergency power supply.
End customers benefit from energy optimization
“Our technology has made reliable resilience and self -consumption optimization possible for years. Today it shows its true value by transforming the greatest challenge of the market – the oversupply of renewable energy – into a direct opportunity for our customers,” says Bradley Mundt, CEO of Plan -B Net Zero. “This means that we prove that a greener future can also be economically successful.”
With the BESS division wants PLAN-B NET ZERO Place more market power in the hands of the end customers, accelerate the farewell of fossil fuels and enable more efficient, decentralized energy system.
