A little heresy on transmission

The last thing renewable energy needs right now are new transmission lines.

This statement is heresy in the green community, but there’s a danger that the increasing focus of green energy advocates on a new nationwide transmission superhighway may undermine the pursuit of near-term renewable energy goals.

People are excited by renewable energy. It’s clean. It’s limitless. It’s local. It’s the one kind of energy source that anyone can harness. Public polls show substantial majorities of Americans in every state favoring more renewable energy.

And states have an abundance of renewable energy assets. A new report by the Institute for Local Self-Reliance—Energy Self-Reliant States—shows that every state has the potential to meet its renewable energy goal or mandate and that 3 in 5 states could get all of their electricity from in-state renewable resources. Almost every state could get at least 20 percent of its electricity from rooftop solar photovoltaics (PV) alone.

These renewable assets can be tapped for significant local benefits. A single wind turbine, for example, creates $1 million in economic activity, according to the American Wind Energy Association. And that’s just a generic, utility size turbine. Locally owned wind projects can create twice the jobs and 3 to 4 times the economic impact of absentee owned projects.

The benefits from locally harnessed renewable energy create a feedback loop, building even greater public support for clean energy.

People are not so excited about new high-voltage transmission lines.

Transmission legislation moving through Congress would preempt longstanding state regulatory authority over transmission line approval and siting. The goal is to speed the construction of a $100 to 200 billion interstate transmission superhighway, bringing solar power from the Southwest and wind from the Great Plains to the coasts.

Why is this problematic? Let’s ignore for a moment that most people wouldn’t care to live by a 150 foot tower running through a 200 foot swath of denuded landscape. Or to have their land seized for this purpose by eminent domain.

Many states oppose the new transmission superhighway for two reasons. One, it’s expensive. Two, it undermines efforts to reap the economic rewards of renewable energy self-reliance.

In a New York Times Op Ed, the Massachusetts Secretary of Energy and Environmental Affairs, Ian Bowles, wrote:

Lawmakers should resist calls to add an extensive and costly new transmission
system that would carry electricity from remote areas like Texas, the Great
Plains, and Eastern Canada to places with high energy demands like Boston,
Chicago, and New York ... Renewable energy resources are found all across the
country; they don’t need to be harnessed from just one place.

In May 2009, the governors of 10 East Coast states wrote to senior members of Congress to protest. Requiring their residents and businesses to pay billions of dollars for new transmission lines that would import electricity from the upper Midwest and Southwest into their region “could jeopardize our states’ efforts to develop wind resources ... “ They added, “it is well accepted that local generation is more responsive and effective in solving reliability issues than long distance energy inputs.”

Nine of the 10 Eastern states whose governors signed the May 2009 letter could get over 80 percent of their electricity from in-state renewable resources, according to Energy Self-Reliant States. And local energy also means fewer legal battles over the siting of unsightly transmission towers, a fact that politicians in that region are unlikely to have overlooked.

It’s not just state energy self-reliance and economic benefits hanging in the balance. A recent study released by Duke University’s Climate Change Policy Partnership throws cold water on the renewable energy transmission passion. It found that the proposed interstate transmission links from regions with low-cost electricity (e.g. the Great Plains) to regions with high-cost electricity (e.g. the East Coast) could enable coal power as easily as renewables, with poor results for carbon emission reductions and other environmental goals.

The evidence undermines the conventional wisdom about high-voltage, long-distance transmission and should raise red flags among advocates. To the people in affected states, a new transmission superhighway is costly, anathema to local energy generation, and a potential enabler of coal-fired power. It creates winners (in the sunny Southwest) and losers (in the “import states” on the East Coast).

A victory for interstate transmission may be at the expense of broader public support for renewable energy.

Renewable energy does not have to be harnessed in a few, select areas and shipped across country. And public support for clean energy may hinge on the opposite.

The ubiquity of renewable energy means that the transition to a clean energy economy can also be a transition to a new, local energy future, where the economic and environmental benefits of powering the economy are everywhere the sun shines.

John Farrell is an Institute for Local Self-Reliance (ISLR) senior researcher specializing in energy policy developments that best expand the benefits of local ownership and dispersed generation of renewable energy. He has written extensively on the economies of scale of renewable energy, the benefits of decentralized energy generation, and the policies and rules that support locally owned and distributed generation of renewable energy.

He authored one of the leading summaries of feed-in tariffs for the U.S. electricity policy market titled, Feed-in Tariffs in America: Driving the Economy with Renewable Energy Policy that Works.

Home-Grown Power

By IAN BOWLES

Boston

PRESIDENT Obama has laid out an ambitious agenda for dealing with our energy needs and climate change: he proposes to double the supply of renewable energy within three years, establish a cap-and-trade program to reduce carbon emissions and use federal stimulus dollars to help homes, businesses and governments use energy more efficiently. This is the right blueprint for increasing the number of green jobs, encouraging economic growth, ensuring that the United States has the energy it needs at reasonable prices, and reducing the risk of global climate change.

But as Congress translates this grand plan into legislation, lawmakers should resist calls to add an extensive and costly new transmission system that would carry electricity from remote areas like Texas, the Great Plains and Eastern Canada to places with high energy demands like Boston, Chicago and New York. This idea is being promoted by energy companies and by elected officials who see it as an economic development opportunity for their particular state or region. Long-distance transmission lines are needed, they argue, to ensure that the president’s energy goals are met.

But there are better — and cheaper — ways to get more clean power flowing to the big cities.

Renewable energy resources are found all across the country; they don’t need to be harnessed from just one place. In the Northwest, the largest amount of green power comes from hydroelectricity. In the Northeast, the best source may be the wind over the ocean, because it blows harder and more consistently there than on land. Offshore wind farms have been proposed for Delaware, Massachusetts, New Jersey and Rhode Island. In the Southwest, solar energy can be tapped on a large scale. And in the Southeast, biomass from forests may one day be a major source of sustainable power. In each area, developing these power sources would be cheaper than piping in clean energy from thousands of miles away.

Unlike our federal highway system, which is needed to transport goods across the country, or the “information superhighway” of the Internet, which is the fastest way to carry information around the world, long-distance transmission lines have no inherent value. On the contrary, the farther electricity is transported, the more of it is dissipated. “Line loss,” as this is called, gobbles up an estimated 2 percent to 3 percent of electricity nationally.

And of course, the longer the power line, the more expensive it is to build. In New England, we estimate the cost per mile at $2 million to $10 million. The closer electricity is generated to where it’s used, the better.

Another component of President Obama’s clean energy vision is the creation of a smarter power grid. But that has little to do with high capacity transmission lines that carry electricity in bulk over hundreds of miles. Building a “smart grid” means upgrading the local grid from a simple delivery system to an information system that can let consumers know the times when power is cheapest, thus enabling them to adjust their use to save money. This flattens out electricity loads and minimizes periods of peak demand. Smart grids will also be able to identify and fix power failures instantly, and someday may even send signals to specific household appliances like thermostats, washing machines and refrigerators to switch them on when demand is low or turn them off during times of peak energy use.

The cost of building transmission lines to connect new power plants to the grid ought to be covered the way we cover it in the Northeast, by folding it into the price of the power that the lines deliver. That allows the market to help keep prices as low as possible.

In Massachusetts, we get about 5 percent of our power from hydroelectric plants in Quebec. Our distribution utilities are negotiating to install a second transmission line for Canadian hydropower, which would be paid for through long-term power-purchase contracts approved by the New England states whose residents use that power. Developers of remote wind-power farms in eastern Canada have said they would also like to sell us electricity, but unless the combined cost of the power they could provide and its transmission is competitive with our other renewable energy choices, their projects won’t get approved. That’s the way it should be.

For a clean energy future, we need a smart grid and we need more renewable energy. The Obama administration is offering welcome support for both. Beyond that, what we need is a level playing field that enables energy providers to compete fairly with one another. The cost of transmission should be incorporated into the overall cost of bringing clean energy to market. Then let the chips fall — and wind turbines rise — where they may.
