Custom run

Configure a scenario and run it through the engine. A worker picks the run off the queue within a few minutes, then it computes in about a minute; you'll be redirected to a live status page to watch it.

Scenario basics

CO₂ price, interest, and demand

Each knob has an initial value (year 0) and a yearly change applied every year after that.

CO₂ price ($/MT)
Interest rate
Demand growth
Advanced: per-source cost assumptions▾

The defaults here are real-world cost figures — capital cost to build, fixed and variable costs to run, plant lifetime, and the maximum share of the grid a source can grow to in a year. Leave these alone unless you want to test a specific assumption (e.g. “what if nuclear were 30% cheaper to build?”).
