Compounds the grid (baseline) tariff each year beyond the last published MSEDCL schedule (FY2029-30). Raises later-year customer savings; the RE tariff and developer economics are unaffected. Default 0 = grid held flat (conservative).

Duty per MH Electricity Duty Act 2016 (industry 9.3% · commercial 21%), auto by category. Banking 8% of energy banked per MSEDCL Circular 346.
The same duty rate also applies on the RE supply, on its total variable cost (RE tariff + transmission + wheeling).

2-hr doubles power vs 4-hr at the same MWh. If you model 2-hr, also raise the BESS inverter $/kWh (~2×) — PCS is sized per kW.
MWh
The solver sizes BESS only in whole containers of this size (default 5 MWh) — every buildable BESS is priced. Smaller = finer search, but slower.

Construction period: 24 months. CAPEX drawn per the schedule below; IDC accrues on drawn debt, so front-loading raises IDC.

% of equity
Group-captive equity is the consumer's slice: drawn at COD, returned at face value at PPA end (interest-free). It lifts the developer IRR above the SPV IRR.

CAPEX splits pro-rata by hard cost into an RE block (solar + wind + land + common infra) and a Battery block, each depreciating on its own book life and tax WDV rate. Only the per-block tax WDV moves the cash returns; book life & salvage feed the book statements.

Set your target IRR and demand, then run the decision engine.
Run the engine to see customer savings, the blended tariff build-up, losses and the 25-year curve.
Run the engine. The financial model shows developer returns at the solved tariff, live-editable via the tariff override.
A dense sweep of the full Solar × Wind × BESS space at your current inputs. Every feasible point is priced to the target IRR; colour is the customer blended tariff. The green diamond is the solver's optimum — the same sizing shown above, priced on the same engine, so the two can never disagree. Resolution controls how densely the surface is drawn (and how long it takes); it does not change the answer — the solver itself exhaustively enumerates the buildable grid (whole battery containers, whole turbines, 1 MWp solar) and the diamond is that exact optimum. Heavier compute with wind on.

Indicative-day dispatch for the solved (or overridden) configuration. Each curve is the hour-of-day average across all 365 days — e.g. the value at 18:00 is the mean across every evening of the year. Hours on the x-axis, average MW on the y-axis.
