The eastern Great Lakes and mid-Atlantic region could rely on wind and solar power for as much as 30 percent of their generation capacity — without threatening electricity delivery — with net benefits even after additional transmission lines and reserve resources are added, according to a preliminary study released by the PJM Interconnection, the region’s grid operator.
The study, by GE Energy Consulting, investigates several scenarios for additions of wind and solar generation to the PJM grid, which extends from New Jersey to to Ohio and parts of Michigan, Indiana and northern Illinois. It calculates the amount of new transmission lines needed to deliver the renewable energy and the required backup generation to support the variable wind and solar power.

For the large metal tower constructed on his land, one farmer will receive annual payments for as long as it stands.
His neighbor, however, whose land is divided by a string of vertical structures, gets a more modest one-time payment.
As a historic transmission build-out continues across the region, landowners are increasingly questioning the fairness of rewarding wind project participants more than those who allow transmission lines to cut across their property.
Frank James, staff director for Dakota Rural Action, says it’s an increasingly common complaint from South Dakota farmers.
“You know what they’re getting paid for those turbines, and it’s pretty good,” James said. “You’re going to get a transmission line that serves those wind turbines and you don’t feel like you’re getting paid as [well].”

As the Senate considers confirming Ron Binz as the next chair of the Federal Energy Regulatory Commission (FERC), rhetoric is heating up and putting the independent regulatory agency in a place it is uncharacteristically but increasingly finding itself these days – the spotlight.
In recent weeks, a few special interests have attempted to paint Binz, and FERC itself, as ploys in furthering the president’s “anti-coal” agenda. But the anti-coal charge doesn’t work when you think through the (still relatively unknown) role that FERC actually plays in energy regulation.
What is it FERC does, exactly?
FERC has several different jobs, none of which allow for favoring particular types of power generation over others. In addition to its authority over gas pipeline permitting and hydroelectric facility licensing, the Commission is charged with ensuring transmission grid reliability, protecting consumers from unreasonable costs, and creating a level playing field for all types of resources that provide transmission or generation services. Richard Caperton at Center for American Progress recently described some of these roles in a great blog post.

The U.S. grid is actually three grids: power generated in the east can’t really move to the west; power generated in the west can’t really move to the east. And Texas – in true Texas fashion – is an electrical state unto itself.
This Balkanized power grid, however, appears to be on the verge of breaking open, with the result that at least some electrons will be free to flow as the market dictates. And that could have particularly positive implications for generators of renewable power.
“This is a ground-breaking project,” said Russ Stidolph, senior vice president and chief financial officer of Tres Amigas, a company that aims to unite the three grids. The project, which has the same name, will be constructed near Clovis, New Mexico, where the interconnections come close to converging.
The developers are seeking $550 million to fund the first phase, which Stidolph said the company expects to begin building by the end of December. The first phase would allow 750 megawatts to move between the eastern and western grids (by way of comparison, the average coal-fired power plant in the U.S. can generate about 550 megawatts). The Tres Amigas developers envision a second phase that would establish a connection between the eastern grid and the Texas grid, allowing for the movement of 1,500 megawatts.

On Aug. 14, 2003, hot power lines sagged onto overgrown trees in Ohio and triggered the largest blackout in North American history, affecting 50 million people from Michigan to Massachusetts.
One of the main causes, according to the joint U.S.-Canada task force that investigated: the failure of FirstEnergy Corp. to adequately manage tree growth in its transmission right-of-way.
The incident — along with million-dollar-a-day fines subsequently passed by Congress — raised the stakes for tree trimming near transmission lines, and many utilities decided not to take chances.
Utility arborists began observing a trend toward clear cutting and indiscriminate spraying that left nothing in its path, often hurting important habitat and blighting previously green spaces.
A group of utility and conservation groups is now trying to convince the industry to give up the bulldozer approach for a more holistic one known as “integrated vegetation management.”

In parts of northern Wisconsin, it doesn’t take a Hurricane Sandy to knock out power for days.
Garden-variety severe thunderstorms routinely leave thousands of customers without electricity in the state’s densely forested northeast corner.
Utility officials hope burying more than 1,000 miles of power lines might bring some relief to customers who are sick of resetting flashing alarm clocks.
Wisconsin Public Services (WPS) received permission from regulators this month to move ahead with the $222 million System Modernization Reliability Project, which some say is too much to spend to improve service for a small number of customers.
The utility, though, says something had to be done to improve the area’s service reliability, which is six times worse than the national average.
“We get complaints from customers who are rightfully pretty frustrated,” WPS spokesman Kerry Spees said.

Kansas is undoubtedly a windy state, but it is not yet the “Saudi Arabia of Wind” that Republican Gov. Sam Brownback wants it to be.
Kansas has more wind energy potential than any state except Texas, but eight states generate more total megawatts of wind power — even as Brownback and his legislature have taken steps to boost Kansas’s wind industry. A key problem: a lack of high-voltage electricity lines to connect the remote areas where turbines churn out power to the bustling regions that demand it.
It isn’t easy to build power lines, particularly those that would have to stretch across several states. A complex—and sometimes conflicting—patchwork of federal and state rules has delayed the completion of some projects and deterred investment.
Now, some lawmakers in Kansas and other states are pitching an interstate compact to streamline that process and add renewable energy to the grid more quickly. A bill to join the compact sailed through the Kansas House this year, and lawmakers in Washington and Missouri have proposed similar legislation.

As more coal plants face retirement, the Midwest’s main grid operator wants to change its planning process to look further into the future.
MISO, which covers the area from Manitoba south to Missouri, has a new requirement that utilities show they have enough power to serve customers for the next 12 months. It relies on a survey to estimate the impacts of EPA regulations beyond one year.
In contrast, the PJM Interconnection, which serves Ohio and parts of Illinois, Michigan and Indiana, has a three-year capacity market that tells it exactly which coal plants will be retired due to EPA regulations and other factors.
Some stakeholders want MISO to follow PJM’s course.
Today, MISO will host a “market vision” meeting to discuss changes to its planning structure. Resource adequacy is one of the changes to be discussed over the next six months.
For some stakeholders, adoption of a PJM-style capacity market would be beneficial since the current Midwest power surplus may turn into a shortage if too many older coal plants retire and are not replaced by other forms of generation.

Federal Energy Regulatory Commission Chairman Jon Wellinghoff, a driving force behind the Obama administration’s efforts to green the electric grid, is resigning.
Wellinghoff told Greenwire Wednesday he’ll stay in his post until President Obama taps a replacement and secures Senate confirmation.
“I expect I will be here for at least several more months and will continue as chairman and voting on matters before the commission,” Wellinghoff said in an email.

Alan Russell calls today’s transmission lines — clusters of steel wires surrounded by strands of aluminum — “a bundle of compromises.”
The steel is heavy and doesn’t conduct electricity well, but it’s needed to support the aluminum, which would otherwise sag too much under the weight of its load.
It’s bulky and unwieldy, but utilities have used the combination since the 1960s, building strong, tightly spaced towers to hold it up off the ground.
Russell, a materials scientists at the U.S. Department of Energy’s Ames Laboratory in Iowa, is part of a team that’s working on a next generation power cable — one that’s lighter, stronger, and more conductive.
The lab is about to begin several months of testing to confirm the strength of their new material, a metal composite made from aluminum and calcium. If they can prove the material has the properties they think it does, the discovery could lead to lower costs for transmission projects.
