Somewhat off topic, but are regulators also considering mandating Basalt rebar in wind tower foundations, prohibiting steel rebar?

I don't know what the re-use story is for foundation plus tower, but it seems to me a bad idea to start with the assumption of rusting out the foundations.

I haven't heard of that here in North America, but I'll add that I'm not up to speed on global developments.

In general, wind turbine foundations are considered to have a fixed lifespan of 25-30 years. If re-powering occurs at end of life, it may be with a larger turbine that requires a new foundation anyway, so not much thought is given to foundation re-use.
