While offshore wind has been working (part time) for many years, Maine continues to overthink how to make it work.

https://www.maine.gov/governor/mills/news/governors-energy-office-s...

Readers Digest version: erect your turbines and wait for the wind to blow.

Occasional results are guaranteed.

Oh, and don't ask about the cost.

Meanwhile, the paralysis by analysis has given new life to onshore wind, which had been becalmed. Just look at Senator Troy Jackson's plan to pave over Northern Maine with newer-bigger turbines as it plays out now in the PUC.

HIGH COSTS OF WIND, SOLAR, AND BATTERY SYSTEMS IN US NORTHEAST

https://www.windtaskforce.org/profiles/blogs/high-costs-of-wind-sol...

 

This article presents the all-in cost of wind, solar and battery systems in the US Northeast.

Table 1 shows the all-in cost of wind and solar are much greater than reported by the media, etc.

 

Much of the cost is shifted from Owners of these systems to taxpayers and ratepayers, and added to government debts 

 

MINIMUM ANNUAL CARRYING COST OF ANY ENERGY SYSTEM

 

Simplified Mortgage Method

 

This method can be applied to Electric Vehicles, Heat Pumps, Electric Buses, Wind Systems, Solar Systems, Battery Systems, etc.

 

The minimum annual carrying cost of a house, or an energy system, is “paying the mortgage”.

With regard to a house, all other costs, such as real estate taxes, heating, cooling, maintenance, etc., are in addition.

 

An energy system must have annual revenues = “Paying the mortgage” + “All other costs”

Any shortage of revenues must be made up by subsidies.

 

The less an energy system is able to “pay for itself”, the more the subsidies.

Subsidies can be reductions in the upfront turnkey capital costs

Subsidies can be reductions of some items of “All other costs”

Subsidies can be paying for the electricity production in excess of market prices

 

A house, after paying the mortgage, likely is worth more than in Year 1.

However, wind, solar, and battery systems have useful service lives of about 20, 25, and 15 years, respectively.

Thereafter, they still perform at lesser outputs for some time, but their financial value is near zero.

 

Complicated Spreadsheet Method

 

A more exact analysis of the economics of an energy system would involve a spreadsheet with many rows and at least 25 columns (for solar), one for each year. It would involve Present Values, Internal Rates of Return, Levelized Costs of Energy, etc.

 

GMP, VT-DPS, VT-PUC, etc., have such spreadsheets, as do I. They would be much too complicated to present here.

 

PART 1

 

Cost Shifting from Owners to Ratepayers and Taxpayers

 

The owning and operating cost of wind, solar and battery systems, c/kWh, is reduced by about 45%, due to subsidies. However, because no cost ever disappears, per Economics 101, the subsidy costs are “socialized”, i.e., added, in one way or another, onto:

 

1) Rate bases of utilities, i.e., paid by ratepayers

2) Taxpayers, by means of extra taxes, fees and surcharges on electric bills and fuel bills

3) Government budgets

4) Government debt

5) Prices of goods and services, other than electricity

 

If the subsidies had to be paid by Owners of wind and solar systems, the contract prices paid to Owners would need to be:


- At least 19.3 c/kWh, instead of 11 c/kWh, for large-scale solar

- At least 15.5 c/kWh, instead of 9 c/kWh, for ridge line wind. See table 1 and URL

http://www.windtaskforce.org/profiles/blogs/cost-shifting-is-the-na... 

 

Shifting Grid Costs

 

Many small-scale solar systems and/or a few large-scale solar systems on a distribution grid would excessively disturb the grid, especially at midday. Battery systems could counteract those output variations.

 

Wind and solar systems could not be connected to any grid without the peaking, filling-in and counteracting services of the CCGT plants, i.e., shutting down CCGT plants, and artificially diminishing/obstructing their gas supply, advocated by pro RE folks, would not be an option for decades, if ever, because of the high costs of site-specific, custom-designed, utility-grade battery systems.

 

Costs not paid by wind/solar Owners:

 

- The cost of extension/augmentation of electric grids to connect widely distributed wind and solar systems

 - The cost of services rendered by other generators, mostly CCGT plants, which counteract the variable, intermittent outputs of wind and solar, 24/7/365

 - The cost of battery systems to stabilize distribution grids, due to variations of the solar and wind system outputs

 

Shifting Owning and Operating Costs

 

The combined effect of cost shifting, determined behind closed doors, increases a project’s annual cash flow, i.e., “left-over-money”, to provide an ample profit for the RE system Owner.

 

RE system Owners are happy, having the “ears” of friendly politicians, saving the world from climate change, and claiming: “See, my project is profitable and competitive”, while everyone else gets hosed.

 

1) Grants from various sources, such as the VT Clean Energy Development Fund

2) 26% federal investment tax credits, plus state FITs. Tax credits reduce, dollar-for-dollar, the taxes GMP pays on profits

3) 100% depreciation over 5 years; the normal for utilities is 20 to 25 years. Write-offs reduce GMP taxable income

4) Deductions of interest on borrowed money. Interest deductions reduce GMP taxable income.

5) Various O&M payments are often waved, such as sales tax, fees, property tax, school tax, municipal tax, etc.

6) RE system Owners sell their output at two to four times NE wholesale rates

 

EXHORBITANT REAL COST OF WIND AND SOLAR ELECTRICITY

 

Pro RE folks always point to the “price paid to owner” as the cost of wind and solar, purposely ignoring the other cost categories. The all-in cost of wind and solar, c/kWh, includes:

 

1) Above-market-price paid to Owners 

2) Subsidies paid to Owners

3) Owner return on invested capital at about 9%/y

4) Grid extension/augmentation

5) Grid support services

6) Future battery systems

 

Comments on table 1

   

- Vermont legacy SO solar systems had greater subsidies, up to 30 c/kWh paid to owner, than newer systems, about 11 c/kWh

 

- Wind prices paid to owner did not have the drastic reductions as solar prices.

 

- Vermont utilities are paid about 3.5 c/kWh for various costs they incur regarding net-metered solar systems

 

- "Added to the rate base" is the cost wind and solar are added to the utility rate base, used to set electric rates.

 

- “Total cost”, including subsidies to owner and grid support, is the cost at which wind/solar are added to the utility rate base

 

- “NE utility cost” is the annual average cost of purchased electricity, about 6 c/kWh, plus NE grid operator charges, about 1.6 c/kWh

for a total of 7.6 c/kWh.

 

"Utility cost" is the annual average price paid for electricity by a utility, about 6 c/kWh,

- “Grid support costs” would increase with increased use of battery systems to counteract the variability and intermittency of increased build-outs of wind and solar systems.

 

NOTES:

1) NE wholesale grid price averaged about 5 c/kWh or less, starting in 2009, due to low-cost CCGT and nuclear plants providing at least 65% of all electricity loaded onto the NE grid, in 2019.

 

- Wind, solar, landfill gas, and methane power plants provided about 4.8%

- Pre-existing refuse and wood power plants provided about 4.6%

- Pre-existing hydro power plants provided about 7.4%

- The rest was mostly hydro imports from the very-low-CO2 Canada grid, and from the much-higher-CO2 New York State grid

https://nepool.com/uploads/NPC_20200305_Composite4.pdf


2) There are Owning and Operating costs of the NE grid, in addition to utility wholesale prices.

ISO-NE pro-rates these O&O costs to utilities, at about 1.6 c/kWh.

 

3) NE charges are for: 

 
Regional network services, RNS, based on the utility peak demand occurring during a month

Forward capacity market, FCM, based on the utility peak demand occurring during a year.

DEEP-WATER FLOATING OFFSHORE WIND TURBINES IN MAINE

http://www.windtaskforce.org/profiles/blogs/deep-water-floating-off...

 

The Norwegians have about 60 years of experience building and servicing oil/gas rigs and laying undersea electric cables, gas lines and oil lines all over the world.

 

They have invested billions of dollars in specialized deep-water, Norwegian harbors and facilities for assembly of oil/gas rigs and invested in specialized sea-going heavy lifters, and specialized sea-going tugboats to tow the oil/gas rigs from Norwegian building sites to oil/gas production sites. The heavy lifters and other ships perform services all over the world.

 

Norway companies want to expand their business by building and servicing and providing spare parts for floating wind turbines for deep-water conditions all over the world

 

NOTE: Norwegians advocating expensive floating wind turbines that depend on the randomness of wind and produce high-cost, variable, intermittent electricity for other people, such as Jane and Joe Worker/Ratepayer, is highly hypocritical, because the Norwegians get 98% of their electricity from their own hydro plants, which produce low-cost, steady electricity (not variable, not intermittent). The Danes advocating wind turbines and boasting about their high percent of wind on their grid is similarly hypocritical, because the Danes have been increasingly using the storage reservoirs of Norway’s hydro plants for decades.

 

First Experimental Floating Wind Turbine in Norway

 

Equinor (formerly Statoil, a Norwegian government controlled company) launched the world's first operational deep-water, floating large-capacity wind turbine in 2009. The turbine trade name is “Hywind”.

 

The wind turbine consists of a 120 m (390 ft) tall tower, above the sea water level, and a 60 m (195 ft) submerged extension below the sea water level, with a heavy weight at the bottom to keep the wind turbine steady and upright, even with very high waves and strong wind conditions. The design was tested and perfected under storm and wind conditions simulated in a laboratory.

 

The 2.3 MW wind turbine is mounted on top of the tower. It was fully assembled in a deep-water harbor near Stavanger, Norway.

 

It was towed to a site 10 km (6.2 mi) offshore into the Amoy Fjord in 220 m (720 ft) deep water, near Stavanger, Norway, on 9 June 2009, for a two-year test run, which turned out to be successful.

 

First Commercial Floating Wind Turbine Plant in Scotland

 

Hywind Scotland project is the world's first commercial wind turbine plant using floating wind turbines.

 

It is located 29 km (EIGHTEEN MILES) off PeterheadScotland to minimize visual impacts from shore.

It has five Hywind floating turbines with a total capacity of 30 MW.

It is operated by Hywind (Scotland) Limited, a joint venture of Equinor, Norway (75%) and Masdar, Kuwait (25%).

 

In 2015, Equinor received permission to install 5 Hywind turbines in Scotland.  

 

Manufacturing started in 2016 in Spain (wind turbine, rotor), Norway (tower, underwater base, assembly), and Scotland (various parts)

The turnkey capital cost was $263 million for five 6 MW turbines, or $8,767/kW.

They were designed to float on the surface, with about 180 m (600 ft) above the sea water level and 80 m (265 ft) submerged below the seawater level.

Total steel weight is about 2300 metric ton, total ballasted weight is about 20,000 metric ton.

Heavy weights in the bottom of the submerged parts serve to keep them steady and upright.

 

The turbines were assembled at Stord in Norway in the summer of 2017, using the specialized Saipem 7000 floating crane, and then towed to the north of Scotland by sea-going tugboats.

Make sure to see the videos showing the crane assembling the entire wind turbine.

Nothing like that exists in Maine, or in the rest of New England.

That means offshore wind turbine assembly and servicing would largely be performed by foreign companies, which already have built the infrastructures and other facilities during the past 25 years.

https://www.youtube.com/watch?v=PmkA6hbJ_j8

https://www.youtube.com/watch?v=bQVU7UaMuck

 

The huge, sea-going, specialized, crane (14,000-metric ton lifting capacity) is required for partial assembly on land and final assembly in an area close to shore with a very deep harbor, before towing, fully assembled, to the site.

 

The finished turbines were towed to Peterhead, Scotland.  

Three  cup anchors hold each turbine in place.

About 2400 meter of chain is required, weighing 400 metric ton, for each turbine.

The Hywind Scotland project was commissioned in October 2017.

 

Hywind Wind Turbines for Demonstration Purposes in Maine

 

Hannah Pingree and other Maine's wind bureaucrats in state government are engaging in mindless prattle, eager to do the bidding of various multi-millionaires and foreign companies that may be providing some wining/dining boondoggle trips to “view the Hywind turbines” in Norway and Scotland.

 

The turnkey cost of those two Hywind turbines would be about $10,000 per kW, versus NE ridgeline wind at $2,000/kW, and regular offshore, south of Martha’s Vineyard, at $4,000/kW.

http://www.windtaskforce.org/profiles/blogs/iso-ne-study-of-1600-mw...

 

That would be at about $120 million for a two 6 MW Hywind wind turbines, plus whatever facilities would need to be built in Maine to support the project.

 

The turnkey capital cost of the wind turbine plant in Maine would be much higher, because Maine does not have the experience of the Norwegians and the specialized equipment and specialized ships, and other facilities. It would be very costly to build those facilities and ships in Maine, or elsewhere.

 

600-ft Tall Hywind Turbines Highly Visible From Mohegan Island, Plus Infrasound

 

The 600-ft tall Hywind wind turbines would be highly visible from Mohegan Island, if they were located TWO MILES east of the island.

 

At that distance, the problem would not be just cyclical, audible noises keeping people awake, but also low frequency infrasound, which can travel many miles, and passes through walls of houses, and can be felt but not heard, and has been shown to have adverse health impacts on people and animals.

http://www.windtaskforce.org/profiles/blogs/wind-turbine-noise-adve...

 

The FAA-required aviation beacons would be clearly visible during nighttime. BTW, they would need to be located about 15 - 20 miles away from Mohegan Island to be unobtrusive to the Islanders.

 

Here is a research report of daytime and nighttime visibility of wind turbines that are about 3 to 4 MW and about 500 ft tall. See URL with photos.

http://visualimpact.anl.gov/offshorevitd/docs/OffshoreVITD.pdf

 

“Study objectives included identifying the maximum distances the facilities could be seen in both daytime and nighttime views and assessing the effect of distance on visual contrasts associated with the facilities. Results showed that small to moderately sized facilities were visible to the unaided eye at distances greater than 42 km [26 miles (mi)], with turbine blade movement visible up to 39 km (24 mi). At night, aerial hazard navigation lighting was visible at distances greater than 39 km (24 mi). The observed wind facilities were judged to be a major focus of visual attention at distances up to 16 km (10 mi), were noticeable to casual observers at distances of almost 29 km (18 mi), and were visible with extended or concentrated viewing at distances beyond 40 km (25 mi).”

 

One has to feel sorry for all the residents of Mohegan Island, but the bureaucrats in Augusta, Maine, do not care about that, because there are not enough votes to stop them. Those bureaucrats are hell-bent to use federal and state grants, subsidies, taxpayer and ratepayer money of already-struggling Joe and Jane Worker to save the world, and to enrich a host of multi-millionaires seeking tax shelters. See Appendix.

 

Some Questions

 

Who are these Aqua Ventus multi-millionaire owners pushing for this expensive project?

How much would be the subsidies?

What would be the energy cost/kWh?

How long would the project last before it would have to be repaired?

How would it be repaired?

Would any special ships, facilities be required?

Does Maine have the required, at least 100-meter, deep-water port?

Is anyone looking at the entire picture on an A to Z basis, or are Maine bureaucrats just dreaming/prattling about castles in Spain?

Does anyone think the Norwegians would not want to make money to maintain/service and provide spare parts for their Hywind wind turbines?

 

Extremely Adverse Impact on CMP Electric Rates

 

LePage’s energy director, Steven McGrath, has focused exclusively on the cost of electricity from the demonstration project.

 

The rate is at least FOUR TIMES above wholesale market value, reflecting the custom design and experimental nature of the platforms.

 

It would start at 23 cents per kilowatt-hour in the first year, escalating at 2.5% per year to 35 cents after 20 years.

 

The PUC estimates it would add up to $208 million over the term, or about $10.5 million a year from Central Maine Power ratepayers. Maine Aqua Ventus had calculated the extra cost would add 73 cents a month to the average household electric bill, in the first year of operation, more thereafter..

  

That is a total rip-off, because Massachusetts pays only an average of 8 - 9 c/kWh over the life of the project.

Main bureaucrats need to learn from Governor Baker.

 

NOTE: The above prices should be compared with NE wholesale prices, which have been about 5 c/kWh since 2008, courtesy of abundant, domestic, low-cost, low-CO2 electricity from gas at about 5 c/kWh, and low-cost, near CO2-free electricity from nuclear at about 4.5 - 5.0 c/kWh.

 

This project is insanity on STEROIDS.

 

One has to feel sorry for the already-struggling Joe and Jane Workers in Maine who will ultimately pay for all this.

https://www.pressherald.com/2018/04/01/effort-to-build-offshore-win...

 

NOTE:

Dear Mr. Greg Kesich, Editor Portland Press Herald

 

(Mr. Greg suggested I write an op-ed regarding the referenced PPH article, so here it is.)

 

This op-ed is in reference to an article on floating wind turbines off the coast of Maine in the Portland Press Herald, dated 20 May 2019.

https://www.pressherald.com/2019/05/20/our-view-blown-off-course-ma...

 

The article states, Statoil had proposed a $120 million demonstration project for two 6 MW Hywind turbines ($10,000/kW) off Boothbay Harbor, but that Governor Page had rejected it. As you recall, his main reason was the higher electricity prices Joe and Jane Worker/Ratepayer would have to pay for 20 years.

 

The article states, Statoil instead took its project to Scotland, where it has invested more than $200 million for five 6 MW Hywind turbines. After some checking, the actual turnkey cost turned out to be $263 million.

 

Scotland got the turbines at $8,767/kW in 2017, but Maine would have gotten the same turbines at $10,000/kW.

 

The article states, “.....and given that country (Scotland) a head start on establishing itself as developer, manufacturer and exporter of offshore technology. Such potential was recognized by the wind energy task force, which was created in 2008 by Gov. John Baldacci and released its findings in December 2009.”

 

That statement is highly naïve and unrealistic. Norway has invested billions of dollars in infrastructures to develop specialized facilities and seagoing ships for shallow-water and deep-water wind turbines during the past 10 - 15 years. Norway has absolutely no intention of establishing Scotland and Maine as competitors.

 

The Scotland/UK actual contributions to the project were:

 

1) Scotland making some parts that were shipped to Norway for assembly

2) Scotland providing the site 18 miles from shore to minimize visual impacts from shore.

3) The UK providing a subsidy of 18.5 c/kWh, plus Statoil selling electricity at about 6.5 c/kWh on the wholesale market, for a total wholesale cost of 25 c/kWh for 20 years. This compares with New England wholesale prices averaging about 5 c/kWh since 2008.

4) The Scotland people paying higher prices/kWh for low-value, variable/intermittent electricity for 20 years that requires the services of other generators for peaking, filling in and balancing year-round. Statoil had to provide a 1.0 MWh li-ion battery system, at a capital cost of about $700,000, to help smooth the flow of the variable electricity from Hywind to minimize disturbances of the Scotland grid.

 

NOTE: If Maine government would have insisted Statoil would build significant infrastructure in Portland, ME, or elsewhere in Maine, Statoil, if willing to do so, would merely have increased the cost of the electricity, c/kWh, to cover its additional costs.

 

NOTE: Massachusetts has signed contracts for 800 MW of offshore wind turbines south of Martha’s Vineyard. If the state government would have insisted the consortium of European companies would build significant infrastructure in New Bedford, MA, or elsewhere in Massachusetts, the consortium, if willing to do so, would merely have increased the cost of the electricity, c/kWh, to cover its additional costs. However, Governor Baker insisted on lowest electricity cost, as that would benefit all of Massachusetts, not just New Bedford, etc. Counting votes is important. See URL.

http://www.windtaskforce.org/profiles/blogs/iso-ne-study-of-1600-mw...

 

NOTE:

School Students Playing with Floating Wind Turbines

 

The main objective with floating wind turbines is to isolate the wind turbine from any wave action, including 30 - 40 ft waves. That can only be done with a long, submerged extension of the wind turbine mast, with a heavy weight inside the bottom of the extension (ballast) to keep the wind turbine steady and upright.

 

Dr. Habib Dagher, Executive Director of the Advanced Structures & Composites Center, should have watched the youtube video, and then given proper instructions to teachers all over Maine, so those teachers could have educated these students regarding the physical requirements, to ensure these students would not waste their valuable time and money building inappropriate models. See URLs and watch both videos.

CO2 Reduction due to Wind Turbines Much Less Than Claimed

 

The Irish Grid

Studies of operating conditions of the Irish grid performed a few years ago showed, at 17% wind on the grid, about 55% of the CO2 was reduced due to wind, instead of the claimed 100%. At higher wind percentages, the percent CO2 reduction would be even less.

 

NOTE: The mantra often promulgated by pro-wind folks is one MWh of wind displaces one MWh of other generation, and as wind uses no fuel there is no CO2, but other generation does use fuel, so that CO2 is avoided. That turned out to be of advantage to pro-wind folks, but is, in fact, highly simplistic.

 

In Ireland, there were years of denial and ignoring of various studies by independent energy systems analysts. Dr. Fred Udo was one of the early analysts of the Irish grid to point out the discrepancy. He was ignored at that time. Another study showed the gas turbines operated near 40% efficiency at 17% wind, whereas, at zero wind, they operated at near 50% efficiency. At that time, the Irish grid had only a minor connection to the UK grid. 

 

The undeniable tip-off was Irish gas imports, which had been predicted to decrease as wind would increase, but had, in fact, not decreased as much as predicted. After much back and forth, the government finally launched an inquiry, which revealed the inefficient operation of the gas turbines at part load (more Btu/kWh, more CO2/kWh), due to the variable, intermittent output of the wind turbines, and their more frequent start/stop operations (high Btu/kWh, high CO2/kWh).

 

Since that time, the Irish grid acquired large capacity connections to the UK and French grids to spread the “discrepancy” over a much larger grid area, which makes it nearly invisible. A Brussels PR problem solved. See URL.

http://www.windtaskforce.org/profiles/blogs/fuel-and-co2-reductions...

 

The New England Grid

Future wind on the NE grid is planned to be about 20% by 2025, i.e., higher than the 17% in Ireland a few years ago, and the NE grid has only minor connections to nearby grids, the same as Ireland a few years ago.

 

At the higher wind percentages, the NE percent CO2 reduction would be even less than 55%, i.e., expensive or inexpensive, variable/intermittent wind is no panacea regarding reducing CO2 and ameliorate global warming.

http://www.windtaskforce.org/profiles/blogs/high-demand-and-low-win...

 

DUCK Curves: DUCK curves due to daytime solar, a minor problem in not-so-sunny Ireland, would impart an additional worsening of grid stability problems after solar would become a significant percentage on the NE grid at noontime in the future.

 

Dealing with the down ramping in the morning as solar is increasing, and the up ramping in the afternoon/early evening as solar is decreasing would impart additional cost/kWh on owners of traditional generators. They likely would be compensated by means of capacity payments by ISO-NE. Those payments should be charged to the disturbers, the solar system owners. However the payments likely would be socialized, i.e., charged to ratepayers/taxpayers.

 

NOTE: If solar system owners were required to install batteries, then the down/up ramping would be avoided, but that would place a cost burden on solar system owners and there would be no end to their complaints.

Comment by Willem Post on October 2, 2021 at 9:26am

Maine offshore winds are stronger than onshore.

AVERAGE capacity factors of 0.40 to 0.45 can be achieved, versus an AVERAGE of 0.30 or less onshore.

However, the turnkey capital cost per MW is at least THREE TO FOUR TIMES as high as onshore, as was proven by the prototype Scotland floating offshore system, which has not been duplicated elsewhere, because of high cost per MW.

HIGH COST PER MW MEANS HIGH COST/ kWh, i.e., about 25 to 30 c/kWh, which is about 5 to 6 times the wholesale price of electricity in New England.

It is off-the-charts nuts to even think about such uneconomical stupidity.

Maine people would be much better served, if the capital were devoted to subsidize the building of thousands of high-efficiency houses.

That measure would actually help people lower their energy bills, and it would reduce CO2, and it would be invisible, and it would make no noise, and it would not screw up the ALREADY SUFFERING fishing industry.

The Scotland system is more than 30 miles from shore and the strobe lights are visible at night, especially during the long winter.

Hannah Pingree on the Maine expedited wind law

Hannah Pingree - Director of Maine's Office of Innovation and the Future

"Once the committee passed the wind energy bill on to the full House and Senate, lawmakers there didn’t even debate it. They passed it unanimously and with no discussion. House Majority Leader Hannah Pingree, a Democrat from North Haven, says legislators probably didn’t know how many turbines would be constructed in Maine."

Maine Center For Public Interest Reporting – Three Part Series: A CRITICAL LOOK AT MAINE’S WIND ACT

******** IF LINKS BELOW DON'T WORK, GOOGLE THEM*********

(excerpts) From Part 1 – On Maine’s Wind Law “Once the committee passed the wind energy bill on to the full House and Senate, lawmakers there didn’t even debate it. They passed it unanimously and with no discussion. House Majority Leader Hannah Pingree, a Democrat from North Haven, says legislators probably didn’t know how many turbines would be constructed in Maine if the law’s goals were met." . – Maine Center for Public Interest Reporting, August 2010 https://www.pinetreewatchdog.org/wind-power-bandwagon-hits-bumps-in-the-road-3/From Part 2 – On Wind and Oil Yet using wind energy doesn’t lower dependence on imported foreign oil. That’s because the majority of imported oil in Maine is used for heating and transportation. And switching our dependence from foreign oil to Maine-produced electricity isn’t likely to happen very soon, says Bartlett. “Right now, people can’t switch to electric cars and heating – if they did, we’d be in trouble.” So was one of the fundamental premises of the task force false, or at least misleading?" https://www.pinetreewatchdog.org/wind-swept-task-force-set-the-rules/From Part 3 – On Wind-Required New Transmission Lines Finally, the building of enormous, high-voltage transmission lines that the regional electricity system operator says are required to move substantial amounts of wind power to markets south of Maine was never even discussed by the task force – an omission that Mills said will come to haunt the state.“If you try to put 2,500 or 3,000 megawatts in northern or eastern Maine – oh, my god, try to build the transmission!” said Mills. “It’s not just the towers, it’s the lines – that’s when I begin to think that the goal is a little farfetched.” https://www.pinetreewatchdog.org/flaws-in-bill-like-skating-with-dull-skates/
