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The electric power grid is based on an outdated hub-and-spoke architecture of centralized power production and distribution through transmission wires.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

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

A nasty winter storm ripped through the northeast December 14, causing a surge in power demand that severely challenged grid reliability for the region. The surge caused electricity demand to peak at 20,182 megawatts (MW), according to the system operator’s reports.[read more]

When it Comes to Our Need for Electricity, Reliability is Essential

Infrastructure Reliability

Over this holiday season in North America the importance of electricity to our very survival has become more evident. On the Friday before Christmas the northeast United States and Canada were hit with a massive ice storm. Hundreds of thousands of people lost power.[read more]

Solar Storage: The New Resilient Clean Energy Technology

November 5, 2013 by Lewis Milford

Clean Energy Group's new Resilient Power Project is helping states figure out how to provide resilient power to critical infrastructure, so that needed services can be provided during a natural disaster that knocks out portions of the electric grid.[read more]

I was recently in Kenya meeting with potential partners for a research project that will measure rural households’ demand for grid connections, as well as the social and economic benefits of bringing people electricity.[read more]

Wind Energy and the Myth of Widespread Negative Pricing

May 21, 2013 by Herman Trabish

wind energy and the grid

Wind only sets the market price if it is the most expensive resource on the system, and that almost never happens because wind has a zero fuel cost. If wind is setting the price, everything else in the area has been turned off.[read more]

Will Smart Grid Advocates & Utilities Heed Lessons Learned from the Telecom Sector?

January 22, 2013 by Christine Hertzog

The electrical grid transformation to the Smart Grid puts tremendous reliance on wired and wireless networks to deliver situational awareness of grid operations. These communications networks enhance and optimize utility management of grid operations, as demonstrated by reduced service disruption times via automated outage reporting by smart meters or voltage conservation programs that reduce operating costs.[read more]
