More capital for battery storage

Steirische Wirtschaft

21 August 2026

Steirische Wirtschaft (issue 16/2026, page 15) describes how Impeto Impact uses BESS Invest to make the economics of utility-scale battery storage projects comparable. The core issue is a lack of transparency: large-scale batteries earn their revenue across four electricity markets and have to make decisions every 15 minutes. Based on 1.3 million historical data points from the past five years, the tool calculates multiple scenarios using the same set of variables. This allows developers, banks and investors to understand how different assumptions affect battery load profiles and revenues. The aim is to mobilise capital for storage projects that make economic sense.

Quoted in the article: "Our tool is meant to mobilise capital for battery storage projects. Interest from Germany is strong as well." — Jim Lefèbre, Impeto Impact

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

pv magazine Germany

22 July 2026

pv magazine describes how BESS Invest uses around 1.3 million historical market data points from the past five years as the basis for multiple scenarios calculated using the same set of variables. This produces business cases for fully merchant battery storage. 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.

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.
