The article looks at revenue modelling for battery storage and the ambition to put investment decisions on solid ground.

New tool for the profitability analysis of merchant battery storage

The result is a business case for fully merchant battery storage that is designed to hold up in project financing. The article places the tool in a market where grid connection and financing — not technology — are the real bottlenecks.

WU study: the economics of utility-scale battery storage depend on many factors

pv magazine Germany

16 April 2026

The article presents the WU Vienna whitepaper "Charging Ahead: Showcasing the Attractiveness of Standalone BESS Investments in Austria". Its core message: whether a standalone storage project is economically viable is decided not by the technology but by grid connection, grid fees, permitting and a robust route-to-market strategy. Revenues come primarily from day-ahead and intraday trading as well as balancing markets — yet as the number of projects grows, so does competitive pressure and the demands on planning, financing and operations.

Jim Lefèbre is a co-author of the underlying WU study.

What we can comment on

We are available to journalists for context, figures and background — in English and German.

Economics of utility-scale battery storage

How revenues from intraday trading, balancing reserve and capacity mechanisms combine into a robust business case — and which assumptions actually move the outcome.

Merchant risk and bankability

Why fully merchant projects are hard for banks to assess, which hedging structures are emerging, and how sensitivity analysis changes financing conversations.

Market environment in Austria, DACH and the UK

Grid connection, permitting and market design as the real bottlenecks of the storage build-out — with a view on the differences between Austria, Germany, Switzerland and the United Kingdom.

Models instead of black boxes

Why we rely on traceable, scientifically grounded simulation for investment decisions rather than on generative AI.
