They are putting in mostly solar (CAT) turbines now, turbine engine, turbine compressor. The turbines require less maintenance, are smaller and are easier to manage emissions. The new turbines are physically a lot smaller than the GE series from the 70s and 80s. The downside to the turbines is that they do not handle small loads well without going into surge, so you end up recirculating a lot of gas just to keep them running in that state.

I think we will see smaller reciprocating engines < 2500 HP, with turbines taking the 1500 HP - 50,000 HP range; the days of the 10,000 HP Clarks are gone.
