Municipal utilities, suppliers and energy park operators decide on large investments at grid connection points: large-scale batteries, PV and hybrid parks. What counts here is not self-consumption but market participation and bankability over 15+ years — precisely the domain EXAIOS was built for.
One point of interconnection with limited capacity, feed-in and off-take caps, and a revenue mix of spot arbitrage, FCR/aFRR balancing and possibly capacity mechanisms. The grid connection is the bottleneck — and the most expensive mistake.
How large should storage and PV be at the point of interconnection, given the connection capacity? Which dispatch maximises the contribution margin across stacked revenue streams? Does the contracted cash flow carry the financing, or does the return hang on the volatile merchant share?
EXAIOS evaluates six scenarios × dispatch × CFO metrics, couples revenue stacking with grid connection constraints and delivers CFADS-DSCR, unlevered IRR and CoE-NPV. The verdict — GO / COUNTER / NO-GO — is deterministic and bankable.
Bankable figures at the point of interconnection: DSCR year by year, p10, tipping distance and the do-nothing comparison. NO-GO cases are stated honestly too. Compute a connection point live.
EXAIOS returns the decisive figures for every site:

Arbitrage, FCR and aFRR are evaluated coupled on the appropriate time scale, not flattered additively — including the physical conflicts between the services.
Almost always. Connection and transformer capacity are hard constraints; EXAIOS sizes storage and PV precisely against them.
