Roosevelt Roads combined cycle

We need power generation in the eastern part of the island. Our governor is promoting 4-5MW in Roosevelt Roads which is a good start but only a start. I am not even sure that would be enough to supply Roosevelt Roads in its current state much less when it starts developing. 

We need someone with some vision to build a 50 or even 100MW combined cycle plant in RR. Someone not including PREPA but perhaps one of the propane importers. This could be done as a microgrid for RR selling excess power to PREPA. Seems like a no brainer to me:

1) Location - At present most power generation is in the south and west requiring long transmission runs. This is not only costly, it is inefficient. Nor is it reliable as we saw with Irma and Maria. RR has plenty of vacant land to site the plant. 

2) Interconnection - PREPA currently has 2 22MW GT generators at Daguao (Ceiba) ab out 1/2 mile from the end of the runway. These were installed in the early 70s to provide reliable power to the Naval station. A plant at RR could tie in at this substation. (I am guessing, I don't know how much could be connected there or how much of the plant output would be available for sale)

3) Fuel supply - Roosevelt Roads is a perfect place to bring in tanker loads of fuel and has existing fuel piers. Space for storage should not be a problem either. Ships or barges carrying oil or propane could dock and offload in the main harbor or in the auxiliary harbor near the drydock. The plant should be multi-fuel so it can use whatever is cheapest at the moment.

 4) Customers - The governor wants to develop industry at RR. Having a plant there would provide primary customers for the juice  and excess could be sold to PREPA. If RR develops industrially, there may even be customers for steam generated by waste heat. 

5) Ruggedness - A CCGT installation would be pretty rugged and should withstand any hurricane with minimal if any damage. This is not the case with wind or solar. 

In a previous note I commented that the new micro-grid regulation, while addressing combined heat and power (CHP) or cogeneration, does not make any mention of combined cycle. I presume it could be used but it should be made explicit. 

For those unfamiliar with the concept of combined cycle, it is this:

An engine, either turbine or reciprocating is used to drive a generator. About 40% of the heat input is used with the rest wasted. The waste heat is recovered and used to drive a second turbine powering a second generator. This allows 60-70% (or more) of the energy input to be used. 

Yes, that is a very, very, basic explanation. A much more detailed explanation is at  https://en.wikipedia.org/wiki/Combined_cycle

The EcoElectrica LNG plant in Penuelas is a combined cycle plant.
