Power flow and line ratings

Ridge Solar and its battery, checked in five steps.

From the project's grid risk to the return a lender can rely on, all in supagrid.

  1. 01

    The project

    130 MW of solar and a 50 MW battery, proposed beside Ridge Road. The developer's case says it captures $61.00/MWh.

  2. 02

    Its grid risk

    Solar farms already on this line lost 9.0% of their output last year, and two constraints did most of the binding.

  3. 03

    Test the revenue case

    Rerun last year with the project in it. It captures $52.00/MWh, 14.8% short of the developer's case.

  4. 04

    The return, and the debt

    At that price the project returns 7.6%, and covers its debt 1.18 times in its tightest year.

  5. 05

    Where each number comes from

    Every figure says where it came from and how it was made, ready for the credit paper.
