What battery storage projects are

Stand-alone battery storage systems (BESS) store electricity from the grid and release it when it is needed. Revenue comes from balancing energy, arbitrage on the electricity market and further flexibility markets. Projects are on offer from project rights to finished systems.

Every listing shows storage power in megawatts, capacity in megawatt hours, status of the grid connection and price in the same form.

What matters with storage projects

For storage, the grid connection is the decisive building block: connection capacity, the grid operator's commitment and deadlines determine whether and when a project can be built. Add to that site security, permit, technology and warranties as well as the marketing concept that produces the revenue.

OMSI 24 checks every listing before it goes live. After the non-disclosure agreement, the provider's grid connection documents, contracts and plans are available for review.

How to buy through OMSI 24

Registration and search are free of charge. After a digitally signed non-disclosure agreement (NDA) you see the address, the detailed data and the provider's documents, and you can ask questions through the platform.

From first interest to closing, OMSI 24 accompanies the process: letter of intent (LOI), negotiation directly with the provider, contract. A commission is due only on success and is already included in the sale price.
