Pittsburgh's Microgrids Technology Could Lead The Way For Green Energy

           

Gene Lutz drives an electric fork lift powered by renewable energy at Pitt Ohio, a trucking company with an office in Harmar, Pa. The firm has invested in solar and wind energy, along with a bank of storage batteries, to create an independent microgrid that would hold up in a storm. Researchers hope to build more of these and link them together to create a reliable backup supply.  Daniella Cheslow/NPR

When President Donald Trump announced the U.S. would withdraw from the Paris climate accord, he said he represented "Pittsburgh, not Paris."

Pittsburgh Mayor Bill Peduto disagreed. He traveled to Germany this week as part of an unofficial delegation of more than 100 Americans, American officials and business owners who say they are still committed to climate talks taking place in Bonn. One element of Pittsburgh's climate strategy has been encouraging innovation in a technology known as microgrids.

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.

Puerto Rico Energy Commission Opens Docket on Microgrids and Distributed Generation

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

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.

Hurricane Maria Has Made Puerto Rico the Land of Opportunity for Solar Power

San Juan, Puerto Rico

Seven weeks after hurricane Maria, the traffic lights are still down in San Juan. The narrow, cobbled streets of the city’s historic center, one of the island’s top tourist attractions, turn pitch black as soon as the sun sets. With appliances useless during the blackout, many of the city’s residents can’t cook, store food, or take a real shower.

Power Line Fails; Darkness Returns to San Juan

SAN JUAN, P.R. — A main power line that serves the northern half of Puerto Rico failed Thursday, knocking out electricity to seven cities that had only recently regained service and dealing a major setback to the island’s desperate efforts to regain normality.

Seven weeks after Hurricane Maria completely disabled Puerto Rico’s power grid, the island was generating just 18 percent of its electrical capacity, returning service to where it had been two and half weeks ago. On Thursday morning, the island had been at about 43.2 percent of capacity.

The disruption also me ant that many people no longer had running water, because pumping stations are powered by electricity.

Puerto Rico's Storm of Misery

cbsnews.com - by Steve Kroft - November 5, 2017

Many Puerto Ricans have endured the longest blackout in American history following a direct hit from Hurricane Maria. Due to a multitude of factors, some say the lights won't be coming back on anytime soon.

It's safe to say that of all the places in the country, the one that is suffering the most right now is the hurricane-ravaged island of Puerto Rico . . . For the past 46 days, most of them have been without power, the longest blackout in American history. FEMA says it has distributed more food and water there than any disaster its ever been involved in.

In Puerto Rico, No Power Means No Telecommunications

wired.com - Adam Rogers - October 10th 2017

Nearly three weeks after Hurricane Maria tore through the Caribbean, Puerto Rico is still mostly an island deleted from the present and pushed back a century or so—with little clean water, little electric power, and almost no telecommunications. For telecom, the biggest problem is the lack of power, because most of the island’s transmission lines were knocked out. “We have to reconstruct the power grid as if we were dropping into the middle of the desert and starting from scratch,” says Luis Romero, vice president of the Puerto Rico Telecommunications Alliance.

Hurricane Maria: Whole of Puerto Rico without power

bbc.com - September 20th 2017

Hurricane Maria has knocked out power to the entire island of Puerto Rico, home to 3.5m people, emergency officials have said.

Abner Gómez, head of the disaster management agency, said the hurricane had damaged "everything in its path".

None of the customers of Puerto Rico's Electric Power Authority had any electricity, he said.

Utilities companies won't let you sell your own solar power. Why not?

The electric utility sector is broken – but the transformation we need will be virtually impossible so long as a handful of wealthy elites are calling the shots

theguardian.com - by Kate Aronoff - August 1, 2017

A new report from the US-based Energy and Policy Institute last week found that investor-owned utilities have known about climate change for nearly 50 years – and done everything in their power to stop governments from doing anything about it.

From their commitment to toxic fuels to their corrosive influence on our democracy to their attempts to price-gouge ratepayers, it’s long past time to bring the reign of privately-owned electric utilities to an end.

Are Solar and Wind Really Killing Coal, Nuclear and Grid Reliability?

           

Lessons from the Lone Star State: A surge in wind power on the Texas grid didn’t cause reliability problems (and brought down electricity prices) because regulators improved the efficiency of wholesale electricity markets. Sarah Fields Photography/Shutterstock.com

theconversation.com - by Joshua D. Rhodes, Michael E. Webber, Thomas Deetjen and Todd Davidson - May 11, 2017

U.S. Secretary of Energy Rick Perry in April requested a study to assess the effect of renewable energy policies on nuclear and coal-fired power plants.

Some energy analysts responded with confusion, as the subject has been extensively studied by grid operators and the Department of Energy’s own national labs. Others were more critical, saying the intent of the review is to favor the use of nuclear and coal over renewable sources.

So, are wind and solar killing coal and nuclear? Yes, but not by themselves and not for the reasons most people think. Are wind and solar killing grid reliability? No, not where the grid’s technology and regulations have been modernized. In those places, overall grid operation has improved, not worsened.
