What would a delay do to this project?

QueueQuant tests this project’s options side by side: waiting for a firm date, taking a non-firm offer, private wire or off-grid supply. It runs each across a wide range of delay and curtailment outcomes, shows which option comes out ahead and where that ranking flips, and sizes every asset on the site for that option: grid capacity, battery power, on-site generation, private wire and backup. It also prices the downside, showing how bad the outcome gets in the worst futures at the risk level you choose.
