Executive Summary
A spreadsheet IRR is useless if it shatters upon contact with a regulatory change. Recently, the CFO of a massive Chemical Company in Gujarat was evaluating a 50 MW Solar Open Access project. On paper, it was a goldmine promising a 15.34% Equity IRR and ₹3.25 per unit in pure savings. The Board approved the ₹262.5 Crore mandate unanimously. But then, the government announced the ALMM mandate, projecting a 25% hike in module costs overnight. Execution was halted, and the Board demanded answers. Here is how we built the exact Techno-Commercial stress-test to show the CFO exactly where his returns would break, and what new tariff he needed to negotiate.
The Setup: The “Goldmine” on Paper
The CFO’s goal was clear: Procure 12.75 Crore units to meet 60% of their total Renewable Energy requirement through a 50 MW Solar Open Access project in Gujarat.
He took the proposal to the Board. On paper, it looked like an absolute goldmine:
- Project Cost: ₹262.5 Crore
- The Gain: ₹3.25 per unit in pure savings
- The Return: A rock-solid Equity IRR of 15.34%
The Board approved the mandate unanimously.
The Constraint: The ALMM Shock
But then, reality hit. The government announced the ALMM (Approved List of Models and Manufacturers) mandate for Open Access projects, forcing developers to procure domestic modules.
In this specific project, modules accounted for ₹105 Crore—a massive 40% of the total CAPEX. Overnight, those costs were projected to jump by 12% to 25%.
The Real Cost: The Boardroom Interrogation
A board member read the news, immediately halted the execution, and called the CFO with three forensic questions:
- “With this ALMM mandate, what happens to our ₹262.5 Crore Project Cost?”
- “If we maintain our ₹3.25/unit savings, how hard does our 15.34% IRR crash?”
- “To protect our 15.34% return, what is the exact new per-unit saving we need to negotiate?”
The CFO was in a tight spot. He reached out to us to decode the exact sensitivities before walking back into the boardroom.
The Verdict: Stress-Test Your CAPEX
We didn’t give him generic advice. We built the exact Techno-Commercial stress-test.
We mapped the hit to his CAPEX and Equity IRR across 12%, 16%, 18%, 20%, and 25% module price hikes. We showed him exactly where his returns would break, and exactly what new tariff he needed to demand to protect his original math.
The reality check for every Corporate Energy Consumer is this: Stress-test your CAPEX before the Board does it for you.

Next Steps for the C-Suite
If your company is actively evaluating an Open Access Term Sheet, do not sign a contract without mapping the regulatory risks to your CAPEX.
