California Grid Expected to Maintain Reliability despite Drought

July 7, 2015 by U.S. EIA: Today in Energy

California Energy and the Drought

According to the North American Electric Reliability Corporation (NERC), the bulk power system in the state of California is not expected to lose any grid reliability this summer, despite a long-lasting drought that has lowered hydroelectric generation.[read more]

Reliability Means Being Connected: We Need a Strong Integrated Electricity System with Nuclear Generation

Nuclear and Energy Reliability

Our economy is completely dependent upon the availability of reliable, clean and economic electricity. So while we may dream of not needing the grid as we each generate our own electricity, what we really need is a strong, interconnected grid made up of reliable economic nuclear power as its work horse.[read more]

Is the U.S. Investing Enough in Electricity Grid Reliability?

The Grid and the Risk of Squirrels

We had a 2-hour power outage at our house last week, together with 45,000 other customers in the East Bay. The lights flickered off just after 8PM and didn’t come back on until after 10PM. Nothing like going without something that you take for granted to make you realize just how valuable it is.[read more]

Electric Reliability and the Clean Power Plan: Perspectives of a Former Regulator

April 23, 2015 by EDF Energy Exchange

Regulators and the Clean Power Plan

There is no great disagreement that the United States energy system is transforming. With or without additional environmental regulations, like the U.S. Environmental Protection Agency’s (EPA) proposed Clean Power Plan, this transition is occurring.[read more]

Pacto Eléctrico Seeks to Bring Reliable Power to Dominican Republic but Questions Remain

April 16, 2015 by Anthony Venezia

In the Dominican Republic during the day you might not even realize the power is out until you hear diesel generators around the neighborhood start to kick in. When it goes out at night you sweat, the only respite from the thick Caribbean heat often being nothing more than a small electric fan.[read more]

Power Can Be Both Clean and Reliable

March 19, 2015 by Doug Vine

A number of analysts have raised concerns that the proposed Clean Power Plan, aimed at reducing power plant carbon emissions, could threaten the reliability of electric power. But a closer look at the U.S. power system and the safeguards in place suggests that these reliability issues are manageable.[read more]

Energy Quote of the Day: Distributed Generation Needed to Strengthen Power Grid

March 5, 2015 by Edward Dodge

Distributed Generation and the Grid

The electric power grid is based on an outdated hub-and-spoke architecture of centralized power production and distribution through transmission wires. This system is highly vulnerable to attacks at multiple points, and failures at critical nodes could create cascading failures and widespread power outages.[read more]

Will the EPA's Carbon Rule Hurt the Grid?

February 25, 2015 by Katherine Tweed

Could the reliability of the electric grid could be compromised if the United States Environmental Protection Agency’s proposed regulations to cut carbon dioxide emissions to 30 percent below 2005 levels by 2030 is implemented as written? This is the conclusion of various independent system operators.[read more]

Energy Access: The First Fridge in Town

Energy Access and Technology

Santosh Chowdhury, a gentleman who lives in the village of Rameshwarpur in India, had just bought a fridge, which may seem uninteresting, but it was the first fridge in his village. The thing about refrigeration that is different than almost any other domestic energy consuming device: it requires reliable 24/7 electricity.[read more]

Modeling a Distribution Network: How Oncor's "Reality Check" Improves Reliability

February 3, 2015 by Chris King

Oncor and Distribution Reliability

Few utilities have a larger or more complex distribution network than Oncor Electric Delivery -- serving more than 7 million Texans, with over 102,000 miles of distribution lines. To help ensure that power keeps flowing, Oncor has created a detailed, dynamic, near-real-time model of its entire distribution network.[read more]

Wind and Solar Energy: Transforming the Grid with Clean Energy, Reliably, Every Day

Clean Energy and Grid Integration

Despite years of successful experience, dozens of studies, and increasing utility support for clean energy, urban myth holds that electricity from renewable energy is unreliable. Yet over 75,000 megawatts (MW) of wind and solar power have been integrated, reliably, into the nation’s electric grid.[read more]

FERC Commissioners: Clean Power Plan Doesn't Spell Doom for Grid Reliability

July 31, 2014 by NRDC Switchboard

All five members of FERC agreed yesterday that acting on climate change is critical and none of them offered any indication that the U.S. EPA’s proposed Clean Power Plan to cut carbon emissions from existing power plants would hamper the reliability of America’s electric transmission grid.[read more]

Study: Weather-Related Blackouts Doubled Since 2003

April 19, 2014 by NRDC Switchboard

I think it was either Cheech or Chong who said, “I’m fed up and sick of this.” Well that’s how many people here in the Northeast where I live feel about power outages caused by storms. If people are sick of it, that’s because they’ve been losing power a lot more often over the last decade.[read more]

Forget Intermittency: NREL Says Wind Energy Can Boost Grid Reliability

January 29, 2014 by Silvio Marcacci

Grid Reliability

We’ve all heard the warnings about how intermittent renewables could “crash” the grid if for instance all of a sudden the wind stops blowing and grid operators are left in the lurch for power when they need it. But what if wind turbines actually improve grid reliability?[read more]

Grid Strain in New England Too Close for Comfort

January 2, 2014 by Kristopher Settle
