Why BESS financial models are hard to get right

Battery energy storage systems (BESS) now play a central part in bringing renewable energy onto the grid and keeping it stable, alongside other economic and operational benefits. Modelling them is complex, and the financial model has plenty of places to go wrong. Investors, developers and operators need an accurate, robust model to make informed decisions and get the most value from a BESS investment.

This webinar compares modelling approaches for BESS projects, with the advantages, limits and best practice of each. It also covers the errors we see most often in BESS financial models, and how to avoid them so your projections are reliable.
