New England's invisible wind-power plants

At least 13 wind-powered electricity plants of industrial size, operating in New England during 2007 through 2012, are easily seen by visitors but invisible to federal government. They don't appear in Form EIA-860 data about plant characteristics, maintained by the U.S. Energy Information Administration, so that the plants are apparently unregistered with the U.S. Department of Energy. [1] They don't look to have been submitting Form EIA-923 data on their electricity generation. [2]

Rated outputs of New England's invisible wind plants, as reported by news media, vary from 1.5 to 6.0 peak MW, with from 1 to 3 wind turbines per plant. Of those plants, 11 are located in Massachusetts and 2 are in Rhode Island; 7 are apparently owned by government and 6 by industry and individuals; 3 plants apparently owned by government have commercial operators: ones in Fairhaven, Kingston and Scituate, MA. Among them, the invisible plants have 20 industrial-size wind turbines, rated at a total of 35 peak MW. Considering the plants with full calendar years of operation through 2012, a wind plant of that size would rank seventh largest in the region.

It's no surprise to find nonreporting wind plants in Massachusetts--New England's capital of trophy-size wind power. Starting in 2009, officials in Gov. Patrick's administration had a windfall--so to speak--millions of federal dollars in so-called "stimulus" subsidies to pass out, funding new wind plants. Aside from the Hoosac and Berkshire Wind projects in western Massachusetts, the Patrick administration channeled its largesse to small and trophy-size plants. Once a turbine was turning and the governor spoke, who cared? The following list identifies the 13 wind plants missing in action and their apparent owners and operators. It references some articles in Web-based news media indicating that the plants have been operating.

New England wind capacity factors

New England's wind industry is in its youth--still at a very rapid rate of expansion. New Englanders who don't live near one of the wind plants tend not to know much about the dimensions of the industry and sometimes lack vocabulary to describe it. "Capacity factor" is one of the industry's key phrases.

The capacity factor for a power source is its actual output expressed as a fraction or percentage of its rated capacity. Although that is straightforward, in New England, at least, wind-energy promoters seem to avoid it. Instead they tend to confuse people by citing how many homes their projects could serve--whatever "homes" might mean. Factories, stores, offices, street lights and homes of different sizes don't seem to interest them. An accurate way to characterize a power source is through the average amount of power it can produce: the rated capacity, multiplied by the capacity factor.

It is usual to find the capacity of a wind turbine rated according to its peak output--during the strongest winds it can tolerate--rather than by its average output as installed, even though average output is usually what matters most. A knowledgeable reader encountering a capacity rating in "MW" will interpret that as meaning "peak MW." Capacity factors for a single turbine, a group of turbines or a whole wind plant are figured against their rarely achieved peak outputs.

Since in most places wind speeds are usually much lower than peak winds, capacity factors for wind turbines and wind plants are usually much less than 100 percent. When reporting capacity factors achieved by wind, with its great variability, measured outputs are often averaged over full operating years, avoiding false impressions resulting from seasonal changes. For example, in New England during a midsummer week a wind turbine may produce only a third the electricity that it produces during a midwinter week.

Accurately estimating a wind plant's capacity factor is a critical element for financial success. When a wind plant falls short of its expected capacity factor, its revenue typically falls short in proportion. To the same degree, it fails to displace conventional generation, with its pollution and greenhouse-gas emissions. So far, New England has only modest operating experience with wind plants of commercial sizes. Estimating the capacity factors for the region's wind plants, even averaged over several years, remains somewhat uncertain.

As of late 2013, there were ten New England wind plants of commercial size--rated 10 peak MW or more--with at least one full calendar year of operation. At that time, only three of the plants, with 78 turbines among them rated at 123 peak MW, had been operating for three or more full calendar years. Following are the numbers of commercial-size wind plants in each state, with their numbers of full calendar years of operation. [1] [2]

                 ME  (2) 1-year  (2) 2-year  (1) 3-year  (1) 5-year
                 NH  (1) 1-year  (1) 4-year
                 VT  (1) 1-year
                 MA  (1) 1-year

For the full calendar years 2010 through 2012 during which they operated, New England's commercial-size wind plants achieved a combined capacity factor of 26 percent. Those plants have a combined rated capacity of 515 peak MW, so their average combined output would have been about 134 MW. That is far less than the region's 20 large natural gas-fired plants, which generated, on average, more than 6,000 MW. Following are the plant names, states and opening years, rated capacities and capacity factors of individual wind plants for those years. [2]

           New England wind-power plants                                                                                    Capacity factors

Plant name	State	Capacity	2012	2011	2010
Mars Hill	ME 2007	42 peak MW	36%	35%	33%
Stetson I	ME 2009	57 peak MW	21%	31%	31%
Kibby Mountain	ME 2010	132 peak MW	23%	24%
Stetson II	ME 2010	26 peak MW	19%	27%
Rollins Mountain	ME 2011	60 peak MW	24%
Spruce Mountain	ME 2011	20 peak MW	32%
Lempster Mountain	NH 2008	24 peak MW	30%	31%	36%
Granite Reliable	NH 2011	99 peak MW	16%
Sheffield	VT 2011	40 peak MW	23%
Berkshire Wind Plant	MA 2011	15 peak MW	36%

When data for calendar 2013 become available, six more commercial-size wind plants will appear in a similar list: Record Hill and Bull Hill in Maine, Groton in New Hampshire, Lowell Montain and Georgia Mountain in Vermont, and Hoosac in Massachusetts (recently renamed New England Wind). These newer plants add a combined rated capacity of 234 peak MW--representing capacity growth of 45 percent in a year.

Operators of Stetson and Rollins Mountain in Maine have noted that those plants were idle or curtailed for substantial periods of 2012, while Central Maine Power installed upgrades to a transmission line, causing an estimated 30 percent loss in total output for the year. [3] [4] The new Lowell Mountain plant in Vermont also experienced severe curtailments. Its operators needed to install a $10.5 million synchronous condenser--a phase-shifting motor-generator--to avoid causing instability on the ISO New England grid. [5]

With a larger and longer base of operations, some countries of western Europe have encountered discrepancies between capacity factors projected for commercial-size wind plants and those experienced. A survey of estimates from project developers, compared with estimates produced by academic researchers and with actual experiences, found a typical developer estimate of 35 percent capacity factor, average academic researcher estimate of 37 percent and average experience of 21 percent. [6] A government survey of the five largest wind development regions in California found an average capacity factor for about 11,600 active wind turbines, during calendar years 2000 and 2001, of about 22 percent. [7]

Experiences in Europe and California were both influenced by many small turbines--under 0.1 peak MW--installed while government promotions during the 1970s and 1980s offered large subsidies. Some either were poorly located or were too closely spaced. [8] More professionally designed and managed wind plants, using the larger and more robust wind turbines produced since the mid-1990s, usually achieve somewhat higher capacity factors. [9]

Nevertheless, for New England we should expect overly optimistic projections from project promoters, and we should be prepared to discount estimates from academic researchers. Not all discrepancies are faults of wind turbines or plant design and operation. In addition to problems during power transmission projects, New England wind outputs have been curtailed to avoid overloading segments of the power grid, called "congestion." [10]

Many practical elements that reduce capacity factors are also often omitted from estimates. Wind turbines are complex machines requiring periodic maintenance. They are exposed to lightning strikes, drastic temerature changes and storms. They suffer electrical, mechanical and control failures. [11] In the snowy country from northeastern Vermont through west central Maine, some roads may remain unplowed in winter. Heavy snow drifts can make back-country roads impassible until spring melt, so that power losses may extend over weeks. [12]

If their rotating components or automatic orientation (yaw control) systems fail, wind turbines can become candidates for disasters. [13] In some accidents, lubricating oil has ignited; turbine compartments have been completely incinerated. [12] In others, heavy blades snapped by strong winds have collided with turbine towers that folded and collapsed. There have been deaths, injuries and wildfires. [14] When turbines of a wind plant are damaged, obviously the plant's capacity factor suffers too.

New England's wind power and politics

In New England, over the past several years, people would often hear of a new wind facility opening--typically with the state's governor or some other politician present. Yet wind still provides only a tiny fraction of the region's electricity. How come?

A look at New England's wind-power plants told much of the story. Although the machines are large on a human scale, their outputs are small on the scale of industry. At the end of 2012, there were 62 active plants rated at 0.1 MW peak output or more. Only 37 were large enough to be reporting generation to the government--rated at 1.0 MW peak output or more. The rest were "trophy" plants: single turbines just big enough to crow about. [1]

	Reporting	Peak MW	Trophy	Peak MW
	plants	total	plants	total
Maine	10	430	2	1
New Hampshire	3	171	0	0
Vermont	4	119	5	1
Massachusetts	20	84	18	6
Connecticut	0	0	0	0
Rhode Island	0	0	0	0
Totals	37	804	25	8

Electricity from these active wind-power plants remained a small fraction of the region's use. The following table shows state electricity use and reported in-state wind-power generation for New England. [2] [3]

	Use	Wind	Wind
	TWh*	TWh*	percent
Maine	11.5	0.88	7.6%
New Hampshire	30.4	0.21	0.7%
Vermont	5.6	0.11	1.9%
Massachusetts	57.1	0.09	0.2%
Connecticut	30.4	0.00	0.0%
Rhode Island	7.8	0.00	0.0%
Totals	142.8	1.28	0.9%

          * TWh, billions of kilowatt-hours

There is substantial flow of electricity across New England states and Canadian provinces. Maine exports most of the wind-generated electricity that Massachusetts and Connecticut import. Massachusetts and Connecticut also import small amounts of wind-generated electricity from upstate New York. [4]

New England has three areas with notable wind potential: (1) a broad swath from northern New Hampshire into central and northern Maine, (2) a north-south spine in western Vermont, dipping into western Massachusetts, and (3) an arc near the Atlantic shoreline extending many miles offshore, particularly around southeastern Massachusetts. [5] With offshore wind very costly and complicated to develop, it could hardly be surprising to find Connecticut and Rhode Island providing no significant wind power.

Today's most productive wind plants in New England are built on mountain ridges: the White and Longfellow Mountains and the Mahoosuc Range of New Hampshire and Maine and the Green and Berkshire Mountains of Vermont and Massachusetts. Conservationist and preservationist movements have sprung up to block the installation of new wind plants and power transmission lines in these areas. [6] [7] [8] So far they have yet to make common cause with similar efforts that focus on the region's southeastern ocean coasts. [9]

Maine has dominated New England's wind power, providing about 53 percent of active capacity at the end of 2012 and about 68 percent of wind-powered generation for the year. Of states participating, Massachusetts came in last with about 10 percent of capacity, although it was by far the leader in trophy plants. In part, that reflected state politics. Govs. Patrick of Massachusetts and Shumlin of Vermont have served as wind gadflies, constrained by finances of wind power and by their state geographies and vigorous protest movements but celebrating, when they can, symbols of what they see as progress.

Former Govs. Baldacci and King of Maine, in contrast, have served as wind promoters--encouraging, finding and participating in financial opportunities for their states. [10] [11] Sen. King's son, Angus King, III, became vice president for mergers and acquisitions at First Wind of Boston--as of 2012 the largest developer of wind power in Maine. Wind power, particularly in Maine, got a boost from the American Recovery and Reinvestment Act of 2009 (Public Law 111-5), adding new subsidies and loan guarantees to previous federal and state benefits.

For the next few years, the future appears to hold more of the same. In 2008, for example, urged on by Gov. Patrick and his departed environmental affairs secretary, Dr. Ian Bowles, Massachusetts enacted a state law requiring increasing amounts of electricity from renewable sources, including wind--called a "renewable portfolio." [12] [13] By 2008, however, Massachusetts utilities were already paying penalties for noncompliance with previous, less demanding state requirements. [14]

In 2008, Gov. Patrick announced a laughable goal to install 2.0 GW of capacity for wind power in Massachusetts by 2020--well after he has left office. [15] Five years later, the state had only 0.09 GW installed and 0.02 GW under review--all as measured by peak power, not the sustained power expected from conventional sources. [1] At first, Massachusetts agencies qualified only in-state renewable sources, but in June, 2010, the state caved in, quietly recognizing that Massachusetts lacked practical potential and accepting imports. [16]

Maine and New Hampshire look likely to expand wind power substantially. As of late 2013, there were ten major projects under review by Maine, New Hampshire and Vermont (with all plants 0.1 MW peak and over counted in the following table). [1]

		Operating/ Under review
	Plants	Turbines	Peak MW
Maine	12/7	226/292	431/730
New Hampshire	3/1	69/23	171/76
Vermont	9/2	46/35	120/80
Massachusetts	38/6	74/10	90/16
Totals	62/16	415/360	812/902

Six projects in Maine and the one in New Hampshire have state-approved contracts with Northeast Utilities, National Grid and Connecticut Light & Power--the major utilities serving southern New England. Those would add 296 turbines and 775 peak MW in capacity, nearly doubling the current size of New England wind power. Sparsely populated central and northern Maine, with its good wind potential, is getting nearly all the attention.

Because rural Maine is little developed, it lacks power transmission capacity. Independent operators of power transmission are not much interested. Lines must be sized for maximum power to be carried, but revenues scale with average power. Serving New England's wind power, with 23 percent average capacity factors, offers poor financial prospects compared with serving its gas-fired power, with 61 percent average capacity factors. [17]

New wind facilities can include power transmission in projects qualifying for state and federal benefits. Some projects have already built tens of miles of power lines, but new ones may have to build hundreds of miles. As that happens, prices of electricity from land-based wind plants are likely to rise beyond levels most recently reported for major utility contracts, [18] although not as high as those reported for offshore wind power. [19]

Renewable energy at a fair price

The Cape Wind project, started by Jim Gordon's company, Energy Management, in 2001, [1] has largely turned into a distraction for renewable energy in New England. It aims to build and operate an offshore wind farm between Cape Cod and Nantucket. [2] The site has very good wind potential, [3] relatively shallow waters and adequate access to power transmission. However, the projected construction cost rose steeply, from $0.5 billion in 2001, [4] for 168 MW annual average (not peak) generating capacity, to $2.6 billion in 2013 for 183 MW. [5] Some owners of oceanfront property have sponsored preservationist campaigns and lawsuits, [6] while the nearest residents are about five miles away from the site boundaries.

Comparable conventional electricity is readily found in Massachusetts. In Cambridge, for example, the Kendall Square station--opened by Cambridge Light and Power in 1949 burning coal--was converted to combined-cycle natural gas by Mirant in 2000 and is now run by NRG Energy. Kendall Square has a current year-round (not peak) generating capacity of 218 MW. [7] For calendar years 2010, 2011 and 2012, it ran at an average 68 percent of that capacity. [7] Its output was somewhat above the average 61 percent of capacity for all large gas-fired plants in New England. It was selling into a New England bulk electricity market with average wholesale prices per kilowatt-hour of $0.051 in 2010, $0.048 in 2011 and $0.037 in 2012--according to ISO New England. [8] [9]

By the end of 2012, Cape Wind had two major contracts to sell bulk electricity for $0.187 per kWh that it has not been able to fulfill, because its offshore wind farm remains unbuilt. [10] [11] That would be about five times the actual, average wholesale price of bulk electricity in New England for 2012. In September, 2013, Massachusetts and Connecticut state agencies approved long-term agreements by Northeast Utilities, National Grid and other utilities to buy bulk electricity from land-based wind farms run by First Wind, Iberdrola Renewables and Exergy Development, at an average wholesale price of less than $0.080 per kWh. [12] [13]

The total capacity of New England's land-based wind power coming under contract in 2013 was nearly twice what was promised by Cape Wind. The price per kWh is less than half the price from Cape Wind. If Cape Wind had built its offshore wind farm at the cost projected in 2001, it too could sell renewable energy at a fair price. [14]
