COMPASS C&I Sizing & Tariff EngineNOW LIVE

Sizing and tariff analysis for C&I supply — a two-sided optimization. On one side, the generator's solar + wind + BESS mix; on the other, the consumers it serves, each with its own load profile. COMPASS holds the generator's equity IRR at target and solves the mix, the consumer allocation, and the tariff for maximum savings on every load profile.

A worked example: one solar + wind + BESS portfolio serving three consumers — a two-shift manufacturer, a round-the-clock data facility, and a day-peaking commercial load. COMPASS holds the generator at its target IRR and returns a single tariff and an allocation that clears each consumer's savings threshold. Sized from either side alone, the same portfolio leaves value on the table for both.

RE Mix & Sizing

Optimal solar, wind, and BESS combination for the load being served — one facility or a portfolio of consumers on 15-minute profiles. Contract demand, ToD structure, and seasonal shape modeled per consumer; the mix is solved against the aggregate.

Structure & Interconnection

Third-party open access and group captive compared across interconnection routes from 33 kV DISCOM-connected to 220 kV ISTS — with the full state charge and loss cascade priced for each: transmission, wheeling, CSS, additional surcharge, standby, and electricity duty.

Tariff & Savings

Landed cost per unit computed against each consumer's DISCOM bill, including ToD arbitrage and demand charge impact. Outputs the PPA tariff that holds the generator's IRR while maximizing annual savings for every consumer served.

Regulatory Sensitivity

Savings tested across surcharge revisions, banking restrictions, grid tariff escalation, and load growth assumptions. Results delivered as P50/P90 bands, not a single-point estimate.

Output: Recommended capacity mix, consumer allocation, procurement structure, and target PPA tariff — with P50/P90 savings projections and sensitivity analysis on regulatory and load assumptions. A C&I PPA runs 15–20 years; the sizing decision deserves the same rigor as the contract.

FAQ

Common questions

Who is COMPASS for?

Generators structuring group captive and open access supply, and the C&I consumers they serve. Both sides of the transaction benefit from sizing solved against real load profiles rather than annual averages.

What inputs does a study need?

15-minute load profiles for each consumer — uploaded directly, or built from 12 monthly billed units with a load-pattern template — plus the DISCOM tariff structure, contract demand, and the candidate sites or resource profiles on the generation side.

What does one study cover?

One supply structure end to end: the optimal solar, wind and BESS mix, the allocation across consumers, a comparison of third-party open access against group captive across interconnection routes, and the PPA tariff with P50 and P90 savings bands.

Which states does it cover?

Maharashtra, Tamil Nadu, Karnataka and Gujarat ship as maintained state packs, each with cited regulatory sources and an as-of date. The settlement engine is back-tested against real DISCOM open-access bills, and new states are added as data packs rather than code changes.

How are regulatory risks handled?

Savings are stress-tested across cross-subsidy surcharge revisions, banking restrictions, grid tariff escalation and load growth, and reported as P50 and P90 bands rather than a single-point estimate.
