imo, that's basically the dirty secret of grid data, post 9/11 it seemed as if everything went behind the CEII wall, but in reality it has always been that if you're a legacy player or have the money you can make sure you have access to everything.

It's a thorny issue and something I ponder in my day-to-day[0]. We're members in ISOs where it makes sense, and can provide CEII data once we've confirmed customers already have access, but I would love to be able to show some of it publicly. It's also odd how things vary from market to market. Transmission outages: public everywhere, except ERCOT, where they're considered Secure. Generator bids: anonymized and delayed by up to 90 days everywhere, except ERCOT, where it's 60-days and not anonymized at all (yes, ERCOT is different wrt to FERC jurisdiction).

Years ago I worked at a market monitor[1], and we got everything, just cloning the changes to ISO databases overnight every day, second-by-second PI (plant information) data, it was awesome. The potential advantages from data asymmetry are big enough that there are multiple companies with physical sensors out in the world measuring power lines in different ways to try and reconstruct grid activity in real time, and then others doing it entirely from access to CEII and a deep understanding of how the grid function. But all of this is heavily oriented towards traders, not developers, although I would use trading tools when developing projects because they were the most advanced.
