BESS Feasibility
Turn a BESS hypothesis into a defensible techno-economic audit
BESS Feasibility combines sizing, load profile, peak shaving, self-consumption, tariff arbitrage and financial KPIs into a shareable techno-economic audit. It is built to quickly establish whether behind-the-meter storage makes sense, which assumptions drive the result and which levers can change the payback. Every number stays traceable, so you can explain to a client or a bank why the business case holds — or why it does not.
The risks of a CAPEX decision made on a fragile business case
Fragile, non-auditable spreadsheets
Feasibility models live in spreadsheets that break at the first change of assumption. Nobody — not even their author — can defend the numbers in front of a client or a lender.
Sizing decided on weak assumptions
Power and energy are chosen by gut feel, without a real load profile or an explicit link to peak shaving and self-consumption. The risk is over-sizing the CAPEX or missing the use case entirely.
No way to explain why the case holds
When the client or the bank asks 'why this payback?', the explicit assumptions and sensitivity are missing. Without a readable calculation chain, the deal stalls.
From hypothesis to an audit you can defend before client and bank
Sizing and load profile
Size power and energy from the site's real consumption profile. Tie the rating explicitly to the use cases — peak shaving, self-consumption, arbitrage — instead of guessing it.
Calculated financial KPIs
Compute LCOS, NPV, IRR and payback over a multi-year horizon with CAPEX, OPEX and degradation. KPIs derive from the stated assumptions, not from hand-entered numbers.
Sensitivity and value levers
Show how payback and NPV move as energy price, tariff spread and cycles vary. You immediately see which levers actually matter for that project.
Shareable audit
Export a techno-economic PDF with assumptions, results and sensitivity. It is the document you put on the client's or bank's table, not an Excel screenshot.
The essentials to turn a storage hypothesis into a defensible techno-economic audit.
“An ESCo team uses BESS Feasibility to turn a C&I client's request into an audit with sizing, financial KPIs and sensitivity in a few hours, with explicit assumptions and a payback that holds up to the bank's review.”
