Reporter Eva Llorens Velez says:
"Some of the senators noted that if Puerto Rico wants to be resilient and produce 30% of the energy with renewable sources, system redundancy must be in place. Bruce Walker, the assistant secretary of the U.S. Energy Department’s Office of Electricity Delivery and Energy Reliability, spoke at length about strategies to make the grid more resilient."
I find that most of the time "renewable" is code for solar and wind, although there are other renewable alternatives (nuclear, landfill gas, OTEC, waste to energy, cogeneration, to name a few).
Getting people to switch from electric to propane for cooking, water heating and clothes drying would save a lot of energy each year even though propane may not be renewable.
I've posted enough on solar and wind that I won't go into why they are bad ideas again.
Whatever else they are and are not, they are NOT resilient. Not in the face of a hurricane.
I drove past last night and most of them were spinning merrily around. 3-4 were stopped but the rest were running.
So perhaps they are undamaged and/or repaired after all.

Why does PRASA still have generators (and 24/7 guards) at pumping stations?
All three of these were running today and have been for months.
These are in rio grande, Luquillo and Fajardo.
Power has been restored at all 3 locations since jan/feb

I drove through Guayama and drove up close to the AES coal plant. There was some steam venting but, looking closely at the heat plume, or rather the lack of a plume, it appeared that the plant might have been offline.
I also drove close to the Aguirre plant. Again, a bit of steam venting but not much of a heat plume.
In Yabucoa, at least 2 of the 3 gas turbines were running and, from the plumes, running fairly hard. Ditto the 2 GTs in Ceiba.

This is a history of PREPA and its antecedents in the electric game. Interesting throughout.

I've said before that I think we need to keep an open mind to nuclear power.
These modular nukes are built in a factory and erected onsite. Perhaps these or something like them is the key to acompact, hurricane proof and sustainable future.

There were no materials hidden in warehouse 5. It was fake news. I don't know who ginned it up or why but am happy to see it put to sleep.

The regional weekly Presencia has an update on the totally destroyed windfarm in Naguabo. The owners say they will rebuild as soon as they get the insurance money.
Me? I doubt it. I expect that 5 years from now the will still be unrepaired. A good thing too as their output is horribly overpriced. 18 cents vs 10-12 for guayama's coal fired and Penuelas' gas generated juice. Us long suffering prepa customers just can't afford it.

Turns out that this was just more fake news. Yes, ARMED!!! federal agents did go to the warehouse but pretty much all federal agents are armed so there is nothing unusual about this. It does works as a headline to get people spun up, though.
El Nueva Dia went to investigate (Good for you, END, for doing your job properly) and here is what they found:
PREPA “Warehouse 5" was no secret
The public corporation attributes federal intervention to a communication problem
However, the Director of Transmission and Distribution of PREPA, José Sepúlveda Aponte, showed this newspaper documents that prove that, shortly after the passage of hurricane María, crews from PREPA and from private companies hired by the public corporation, as well as the Corps of Engineers, started looking for materials at that warehouse.
"All the new metal (transmission) towers that have been installed came from warehouse 5. It is the only warehouse with that material," he said.
Between September and October, about 200 requests were made, mostly by PREPA crews, according to the logbook shown to this newspaper. There are also entries made by Whitefish and Cobra companies.
As of October 28, there are entries of private crews hired by the Corps of Engineers, such as one made by Flour-Pike on October 28 for works on line 36800 in Canóvanas. There is also an entry on November 11 for that same line.
Meanwhile, on November 18 a crew of the New York Power Authority, also subcontracted by the Corps of Engineers, appears. In another document he highlighted that Fluor was also in the warehouse in December, as well as Con Edison.
There was no information available about entries made after December.
Read the whole thing. My guess is that this was a political "SWATing" designed to gin up controversy. Much like the fake controversy that was ginned up over Whitefish.

There are a number of interesting comments posted on the proposed microgrid regulztion. Here's the link to them

In an earlier post https://darkislandpr.blogspot.com/2018/01/microgrid-regulations.html I had linked to the proposed microgrid regulations, expressed my support and mentioned a couple of comments. I finally got them written up and submitted. My complete comments are below
