Company of the future
The OK Power Plus seal of approval is one of the strictest green electricity labels in Germany and guarantees consumers that their electricity comes from 100% renewable energy while making a real contribution to the energy transition. Suppliers who carry the seal must not only prove that they source clean electricity, but also actively promote the expansion of new renewable energy plants and must have no connections to nuclear or coal-fired power companies.
In addition, PLAN-B NET ZERO was awarded the ‘Company of the Future’ seal in 2025.

Everything from a single source
PLAN-B NET ZERO brings together what is separate elsewhere: the entire value chain under one roof — from generation, storage, and control to supply for our end customers.
We invest specifically in solar, wind and storage facilities and feed 100% renewable energy directly into the grid – decentralised, emission-free and scalable. This ensures that green energy is generated where it is needed.
Our smart storage and load management systems ensure that renewable energy is not lost. Instead, it is provided as needed – for maximum security of supply and a stable grid.
We work with our own sales department. Clear tariffs, digital service and genuine customer access ensure a relationship based on mutual respect.
Our software manages energy intelligently – in real time, data-driven and tailored to demand. With smart interfaces and adaptive algorithms, we make renewable energy supply predictable, efficient and intuitive to use.
Our solutions are tailored to the requirements of trade and industry and combine ecological responsibility with economic efficiency. Whether cost savings, a better carbon footprint or a strong brand profile: with PLAN-B, energy becomes a strategic decision.
