Missing a connectivity milestone used to mean losing connectivity. Since August 2026 it means paying to keep it — per MW, per day, at a rate that climbs.
Group captive turns on two numbers
· 7 min read · Constructs
26% of the ownership, 51% of the generation — and since the 2026 amendment, both counted across the plant rather than shareholder by shareholder.
100 MW of firm power needs about 300 MW built
· 8 min read · Constructs
FDRE and RTC contract a shape, not a quantity. Holding a firm line with variable sources takes roughly two and a half to three and a half times the contracted capacity.
Reading a tender as a set of constraints

Sixty pages, about five numbers that fix your configuration. What to extract, in what order, before opening a model at all.

· 6 min read · Diagnostics
Inverter clipping, an evacuation cap, a grid instruction and contractual curtailment. Same word, four causes, four owners — only one is anyone’s fault.
P50, P90, and which one belongs in which number
· 6 min read · Statistics
P50 sizes the tariff you bid. P90 sizes the debt the lender will lend. Using one where the other belongs is the quiet error in a first bid model.

· 6 min read · Measures

“100 MW solar” is a procurement label, not a design. The design is six numbers, and each one moves generation, cost and tariff independently.
Nothing here matches that. Try tariff, curtailment, P90 or storage.
Looking for the vocabulary instead? The renewable energy glossary defines every term the model uses.
