It prices the deal,
and shows you the work.

• ▸The deal starts from a storage facility, which brings its own tariff and the one curve its location prices from.
• ▸Monthly injections, withdrawals and ending inventory, with the NYMEX benchmark, the Houston basis and the all-in price for each month.
• ▸What a NYMEX futures hedge leaves behind: the benchmark goes to zero, the basis does not.

• ▸Hour-by-hour dispatch at ERCOT North, with charge and discharge kept separate rather than netted.
• ▸A notional stated for what it is: capacity, megawatts times delivery hours, not energy delivered.
• ▸A 20% resize re-priced from scratch: value scales, the par rate does not move.

The demo curve prices each day in a few flat time-of-use blocks, so the intraday shape reflects those blocks rather than a real hourly profile.

• ▸A 50 MW PPA at PJM Western Hub on a weekday peak 5x16 schedule, filled in and priced from a plain request.
• ▸The computed delivery hours and delivered energy, then a capacity change re-priced.
• ▸The hub's forward curves and published day-ahead settlements, split into energy, congestion and losses.

• ▸A toll at ERCOT North against Henry Hub gas, valued on hourly power blocks and monthly gas.
• ▸The spread the plant captures: power revenue, less gas at the heat rate, less the cost of starting up.
• ▸A breakdown the preview did not return, flagged as missing rather than estimated.
