    Which land near the grid suits a project?

    Siting covers land near the grid, and its route to a connection.

  • Coming soon

    What changes for the project if a new line goes ahead?

    Line edits in modelling let you add or upgrade a line, then rerun the market.

A 200 MW solar farm near Mill Creek, in five steps.

From the site on the map to the return it would have made, all in supagrid.

  1. 01

    Find the site

    The Mill Creek–Ridge Road line runs past it, Mill Creek has 160 MW of headroom, and a 150 MW wind farm is queued ahead of it.

  2. 02

    Check the lines

    The Mill Creek–Ridge Road line ran close to its rating on most spring afternoons last year, carrying the farms already out there.

  3. 03

    Check curtailment

    Solar farms nearby lost about a tenth of their spring output, mostly to that one limit.

  4. 04

    Rerun last year

    Add the farm and rerun last year's market around it. It would have earned about $19m, and lost 7.8% of its output to curtailment.

  5. 05

    See the return

    With build costs from the cost book, that is a 7.9% return over 30 years, with the debt covered 1.30 times in its tightest year.
