Infographic: Here’s How the Grid Works

Friday, October 14th, 2016
the grid - thumb

With more than 450,000 miles of high-voltage transmission lines (not including distribution lines), the US electricity grid is clearly a behemoth. But how many times have you really given a thought to this huge, incredible network that generates electricity, carries it miles and miles, and powers our Netflix binges, our holiday lights, and our refrigerators? Here’s the breakdown, from the Energy Department:

Emerging Issues: Integrating Solar Energy

Achieving the U.S. Department of Energy’s SunShot Initiative cost targets could greatly accelerate deployment of grid-integrated solar technologies. Global experience with increasing amounts of wind and solar on power systems has shown that variable generation resources can be integrated into the grid at penetrations well beyond current capacity. However, the prospect of dramatically increased photovoltaic (PV) deployment requires detailed examination to ensure that high-penetration solar technologies will provide their intended benefits, including reducing fossil fuel use and reducing the conventional capacity needed for reliable service.

Electric grids have always been vulnerable to natural hazards and malicious physical attacks. Now the U.S. faces a new risk—cyberattacks—that could threaten public safety and greatly disrupt daily life.

Guest on The Infra Blog: Bill Peduto, Mayor of Pittsburgh

Bill Peduto

William Peduto was elected to the office of Mayor of the City of Pittsburgh in the General Election on November 5, 2013. He has worked for 19 years on Pittsburgh City Council, as a staffer and Member of Council representing District 8, and resides in the Point Breeze neighborhood of the city.

“So there’s always been a partnership between the ability to create and innovate and the ability to build—that’s in our DNA. We went through a thirty-year recession/depression, and now we have re-emerged where we were before, which is with a new 21st-century model. When we look at our infrastructure, we have the opportunity to be innovative once again.”

Analytic Research Foundations for the Next-Generation Electric Grid

NATIONAL ACADEMIES PRESS
Mathematical modeling and control of the electric grid has been an active area of research for decades. However, in 1996 a major outage that affected 11 Western states and 2 Canadian provinces—coupled with emerging concerns that computers would malfunction after December 31, 1999—increased awareness of a lack of complete understanding of the overall system and its frailties. For several decades the Electric Power Research Institute funded a program of research to develop tools for recognizing early signs of instability and means to counter them. That research was largely of a mathematical nature.

Lights Out? Storm Surge, Blackouts, and How Clean Energy Can Help

UNION OF CONCERNED SCIENTISTS
To maintain our present and future access to reliable electricity—and all the health, safety, and economic benefits such access allows—we must prepare our electric grid for increased coastal flooding. One necessary approach is adapting electricity infrastructure. However, it is also critical to simultaneously pursue solutions that go beyond intervening with specific pieces of equipment. For that, we can look to bolstering the overall electricity resilience of critical facilities and vulnerable populations.

ADVANCED ENERGY ECONOMY INSTITUTE (AEE INSTITUTE)
California’s portfolio of policies, statutes and regulatory actions, whether existing or proposed, has set the state on a path to significant de-carbonization of its energy sector. When coupled with broader industry and societal trends, a transformation of the grid is underway at both the wholesale and retail levels.

Graham Richard, CEO, Advanced Energy Economy (AEE)

Graham Richard is CEO of Advanced Energy Economy (AEE), a fast growing national association of businesses working toward a prosperous future based on secure, clean, affordable energy, and CEO of the Advanced Energy Economy Institute, AEE’s charitable and educational affiliate.

“We’re seeing consumer power has been growing, meaning the clout that consumers have in many different dimensions of our economy. And I see that happening now in energy. In that same opportunity where consumers want to know where that power’s coming from, they want to know what the cost is—but they’re also willing, when you have an opportunity to explain what the technology could do, to improve that aging infrastructure.”

Easing the Transition to a More Distributed Electricity System

Friday, March 6th, 2015

INTERSTATE RENEWABLE ENERGY COUNCIL (IREC)
In recent years, new technologies have emerged on the customer side of the electric system, including distributed energy resources (DER) such as distributed generation, energy efficiency, electric vehicles, energy storage and demand response technologies, among others. These technologies are allowing growing numbers of energy consumers to decrease their electricity demand, act as energy producers and otherwise manage their energy usage…Together, these compounding factors have driven the movement toward a more modern grid that enables significant increases in the amount of clean energy produced; universal consumer access and facilitation of consumer choice, including the adoption of DER; integrated resource planning; two-way flow of energy and information; and increased reliability, security and resiliency.

Infographic: Understanding the Electric Grid

Ever since Thomas Edison and Nikola Tesla battled it out during the War of the Currents in the late 19th century, electricity has been a central part of life in America. We are constantly connected to the power grid, which keeps our food refrigerated, our homes heated, our computers running and our rooms lit. Power lines, transmission stations and power plants have become a part of the landscape — to the point that we hardly notice them.
