Ryhla
Models the distribution grid feeder by feeder, so developers pick sites before filing.
Ryhla builds models of distribution and subtransmission feeders, trained on proprietary data and backtested against actual utility study results, so a developer can check whether a 1–50 MW project (solar, storage, EV charging, small data centers) will get capacity before paying to file and waiting months to find out. Feeder-level coverage today spans named utilities: ComEd in Illinois, PG&E and SCE in California, three New York utilities, PSE&G, Oncor, Dominion, Xcel and Georgia Power. It's backed by Y Combinator, founded by engineers from École Polytechnique and Stanford's grid-intelligence research.
What holds up
- +Backtested against actual utility study results, not just a theoretical model
- +Lists the exact utility territories covered today by name, instead of a vague "nationwide" claim
- +Targets the real cost problem directly: filing, paying and waiting months to learn capacity isn't there
- +Backed by Y Combinator, a concrete funding and vetting signal
Mind the limits
- −Coverage is limited to the named utility territories listed — other regions require asking if they'll add it
- −Aimed squarely at 1–50 MW developers, not residential-scale or much larger utility-scale projects
