Development schedule by electricity market: a Gantt with leads and lags

8 markets · Operator step durations as published · Built October 17, 2026

Months from the interconnection request, market by market. Green bars are the operator's own published step durations placed end to end; amber dashed bars are lags the rules impose (a wait for the next window, a decision point, a deadline to elect the next study); purple bars are leads, developer work that a source says must start before a later milestone; blue bars are developer work that runs alongside the studies; grey bars and the operation marker are site-created illustrations, not market-specific forecasts. A lighter tail on a bar is the range between the minimum and maximum the source gives.

What this is not. Not a schedule for your project: operator steps slip (MISO's 2021 cycle was still finishing in 2026), windows move, and developer-side bars use illustrative positions. Bars follow the shortest illustrated sequence; longer ranges and optional restudies shift later work. This is not a complete critical-path model. Use the chart to see where the waits are and which work has to start before the agreement, then build your own from the sources listed under each chart. Current windows and dates are on the interconnection page.

ERCOT staff: 18 to 30 months from request to commissioning for 10 MW and up, before construction or supply delays. Berkeley Lab (2026 edition): about 24 months to an agreement in ERCOT on average; 61 months to operation for the typical project built in 2025 across regions.

How this page was made

Green operator bars use published durations from the interconnection page and placed end to end from the request date; ranges are drawn as a lighter tail. Developer-side bars use the handful of durations a public source actually states (transformer lead times, the Phase I shelf life, Corps and THC review clocks, ERCOT's 180-day commissioning limit, land-agreement terms) with illustrative placements for parallel work and the operation marker. National medians do not establish project construction duration. Where a placement is this site's own arithmetic, the note under the bar says so. Nothing here is advice.
