STORAGE FINANCING
Wattvalio builds the financing business plan for a battery storage (BESS) project: funding plan, bankable debt, revenue stacking, cycles and degradation, returns and valuation — a bankable financing package, recalculated in real time.
Arbitrage, ancillary services, capacity — and PV+BESS hybridisation to smooth cash flows.
Round-trip efficiency, cycles/year, capacity degradation — the ageing that weighs on bankability.
Battery/grid CAPEX, equity contribution, senior debt, construction schedule.
Covenant-based sizing (DSCR/LLCR) on more volatile revenues, sculpted debt, RCF, DSRF.
Corporate tax, CVAE, C3S — modelled, not approximated.
Project/equity IRR, NPV, MOIC; DCF and NAV/SOTP, project to portfolio.
The battery storage (BESS) financing business plan stands out for more volatile revenue (arbitrage, ancillary services) and capacity degradation. Wattvalio models revenue stacking, cycles and degradation, sizes debt to a covenant (DSCR/LLCR) and consolidates project to portfolio — for a bankable package fit for a bank syndicate, standalone or as PV+BESS.

It is the business plan that proves a storage (BESS) project is bankable: funding plan (CAPEX, equity, debt), revenue stacking (arbitrage, ancillary services, capacity), cycles and degradation, debt ratios (DSCR, LLCR), returns and valuation. It is the document handed to the bank and the investment committee.
By sizing debt prudently (DSCR/LLCR covenant) on contracted or stressed revenue, and by modelling the degradation that reduces usable capacity over time. Wattvalio recalculates DSCR and sculpts debt accordingly.
Yes: you can model a solar plant with adjacent storage (PV+BESS), with revenue stacking and project debt consolidated.
