pv-magazine-usa.com - by Christian Roselund - February 7, 2019

PREPA’s draft IRP calls for rapid deployment of solar and batteries, including the installation of as much battery storage as is currently online in the entire United States over the next four years, in a system broken up into “minigrids”. However, it stops short of utilizing behind-the-meter PV and storage . . .

 . . . PREPA’s final IRP is scheduled to be published on February 12.

Solar energy is becoming more and more popular as prices drop, yet a home powered by the Sun isn’t free from the grid because solar panels don’t store energy for later. Now, researchers have refined a device that can both harvest and store solar energy, and they hope it will one day bring electricity to rural and underdeveloped areas.

The problem of energy storage has led to many creative solutions, like giant batteries. For a paper published today in the journal Chem, scientists trying to improve the solar cells themselves developed an integrated battery that works in three different ways.

How Storms, Missteps and an Ailing Grid Left Puerto Rico in the Dark

           

A transmission tower and downed lines in the mountainous terrain of eastern Puerto Rico. Workers from the island and throughout the United States have worked to restore power after Hurricanes Irma and Maria last September.

It took months to restore electricity in Puerto Rico after hurricanes dealt a one-two punch. Many homes are still without power, and the system’s future is far from certain.

 . . . After Maria and the hurricane that preceded it, called Irma, Puerto Rico all but slipped from the modern era . . .

 . . . an examination of the power grid’s reconstruction — based on a review of hundreds of documents and interviews with dozens of public officials, utility experts and citizens across the island — shows how a series of decisions by federal and Puerto Rican authorities together sent the effort reeling on a course that would take months to correct. The human and economic damage wrought by all that time without power may be irreparable.

Tired of Waiting for Electricity in Puerto Rico, Man Builds His Own Solar Power System

           

Frank says his experience with electrical work helped him tackle the solar panel installation.

cnn.com - by Paul P. Murphy - April 19, 2018

Another day, another blackout in Puerto Rico; Wednesday's blackout was the latest to hit the island still recovering from Hurricane Maria. But one man beat the power outages and his troublesome gas generator by switching to solar power.

"As I'm typing this, we are in the middle of a blackout and my fridge, lights and fans are running worry free," a man named Frank told CNN.

Explosion, Fire at Power Plant Cause Blackout in Northern Puerto Rico

           

cbsnews.com - February 11, 2018

An explosion and fire at an electric substation threw much of northern Puerto Rico into darkness late Sunday in a setback for the U.S. territory's efforts to fully restore power more than five months after Hurricane Maria started the longest blackout in U.S. history. The island's Electric Power Authority said several municipalities were without power, including parts of the capital, San Juan, but they were optimistic it could be restored within a day as they worked to repair a substation that controls voltage.

The blast illustrated the challenges of restoring a power grid that was already crumbling before it was devastated by the Category 4 hurricane.

Re-energizing the Island: Power in Puerto Rico

The primary transmission lines that criss-cross Puerto Rico are steadily coming back online following Hurricane Maria, with several different contractors responsible for bringing back power.  The island lost all of its power after the storm; it still has a goal to restore 95 percent of power by the middle of December.

Power Restoration After Major U.S. Hurricanes

Power relief efforts for Hurricane Wilma and Irma were aided by utilities’ ability to access power from utilities in other states through the existing interstate transmission system and the nearby availability of workers to help restore the system. Hurricane Maria knocked out power to all 1.5 million customers in Puerto Rico, and its island locale means it cannot draw on other nearby electrical grids. Additionally, with key infrastructure like ports and airports out of service, workers have been prevented from arriving, and efforts to assess the damage have been much slower.

Puerto Rico Energy Commission Opens Docket on Microgrids and Distributed Generation

Puerto Rico Gov. Ricardo Rosselló Nevares testifying on Capitol Hill this week.

microgridknowledge.com - by Elisa Wood - November 17, 2017

Puerto Rico’s energy commission has opened a docket to investigate ways to encourage microgrids and distributed generation to build an energy system with more fortitude against hurricanes.

Island officials described the docket this week in testimony before the U.S. Senate Committee on Energy and Natural Resources. Half of the island’s population remains without power two months after Hurricane Maria’s strike.
