Techno-economic modelling for renewable projects
Optimise IRR and LCoE across hundreds of inputs. Sub-hourly simulation of consumption, generation, and storage, modelled on the market rules that apply to your project.
What it does
Multi-scenario techno-economic optimisation, IRR-first: sizing and dispatch solved together in one physics-constrained linear program, kept tractable at full sub-hourly scale, across 100+ inputs spanning demand, generation, technology, finance, and policy, with your market’s tariff and banking rules modelled exactly. Outputs are decision-grade: optimal capacities, LCoE, IRR, DSCR, payback, and Monte Carlo P50/P90 ranges on cash flows from 15-minute to annual, in minutes.
What you get
Sub-hourly modelling
Consumption, generation, and storage modelled at 15-minute resolution from 12+ months of meter data, capturing the intra-day swings annual averages miss.
Multi-scenario optimisation
Co-optimise solar, wind, and storage in one run for IRR, LCoE, demand met, or a CfD strike, with Monte Carlo sweeps across capex, tariffs, and financing.
Regulation-aware constraints
Market rules as hard constraints: ToD bands, wheeling and banking, DSM limits, RPO, captive shareholding, and DSCR covenants.
Financial-grade outputs
LCoE, IRR, DSCR, payback, and NPV of savings. Full P&L and cash flows from 15-minute to annual, export-ready for committee and lender review.

Why the numbers hold up
One solve, not three spreadsheets
The engine optimises dispatch, sizing, and financial structure together at 15-minute resolution, formulated to stay tractable at that scale. Trade-offs are priced inside one provably optimal solve, not reconciled between models.
Physics as hard constraints
Generation curves, degradation, and inverter behaviour are constraints, not assumptions. The model cannot produce what the plant cannot deliver.
Uncertainty, quantified
Monte Carlo propagates uncertainty through every scenario: P50/P90 ranges with sensitivity bands, not single-point estimates taken on faith.
