The citizens of Maine have not been informed of this vast transformation requirement
The offshore wind plan calls for development of 3,000 MW of generating capacity, an amount that is roughly double Maine’s average electricity usage. The viability of Maine’s offshore wind plan depends entirely on the massive transformation of the state’s grid from fossil fuel use to electrification. It is clear that the citizens of Maine have not been informed of this vast transformation requirement. They have certainly not approved it.

World's first floating wind farm Hywind Scotland faces shutdown for 'heavy maintenance'
Norway's Equinor confirms component changes needed on all five Siemens Gamesa 6MW machines operating since 2017
.
One of five 6MW Siemens Gamesa being towed out to Hywind Scotland in 2017
Norwegian energy giant Equinor will temporarily remove all five floating wind turbines from the pioneering Hywind Scotland array later this year after discovering a need for “heavy maintenance” on the Siemens Gamesa machines deployed there, Recharge has learned..
The 6MW turbines will be towed back to Wergeland on the west coast of Norway, as part of a maintenance program that is likely to take around four months and will disrupt power output from the project operating 24 km off Peterhead since 2017.
.
All units will be reconnected back on the Hywind Scotland site when the maintenance is complete, a spokesman for the Norwegian company confirmed.
.The work will involve changing various components, including bearings on the turbines, as well as increased routine maintenance in the future..“What we see from operational data, such as excessive stresses on bearings, points to the need for… heavy maintenance on the turbines,”.The cost of towing from Scotland to Norway, repairs and lack of production, towing from Norway to Scotland and reconnecting, will be significant..If such wind turbines were installed in Maine, round-trip towing, and lack of production would be much greater.

UK 50 MW Kincardine floating wind system was placed in service on October 2021
It produced 144 GWh in 2023
It was predicted to produce 200 GWh
CF = 144000/(8766 x 50) = 0.329, a far cry from 0.457 predicted by proponents
Located 15 km off the coast of Aberdeenshire, Scotland, water depths 60 to 80 m
It has five Vestas V164-9.5 MW and one V80-2 MW,, each installed on WindFloat® semi-submersible platforms, designed by Principle Power.
https://www.offshorewind.biz/2021/10/19/worlds-largest-floating-off...
Operating results in year 2023:
All numbers are in UK pounds
Cost = Finance 30 mil, Admin 5 mil, Other 46 mil = 81 mil
Production cost 81000000/144000 = 562/MWh
Income =Tax credit 6 mil, Subsidy 31 mil, Sales 13.3 mil = 50.3 mil
LOSS without subsidies = 81 - 13.3 = 67.7
LOSS with subsidies = 67.7 - 37 = 30.7
It operates under a PPA at 92/MWh and receives subsidies at 125/MWh, for a total of 217/MWh.

Unaffordable Wind, Solar, Battery Fiasco Will Impoverish New England for Many Decades
https://www.windtaskforce.org/profiles/blogs/unaffordable-wind-sola...
By Willem Post, Energy Systems Analyst
Floating Offshore Wind Systems in the Impoverished State of Maine
https://www.windtaskforce.org/profiles/blogs/floating-offshore-wind...
Despite the meager floating offshore MW in the world, pro-wind politicians, bureaucrats, etc., aided and abetted by the lapdog Main Media and "academia/think tanks", in the impoverished State of Maine, continue to fantasize about building 3,000 MW of 850-ft-tall floating offshore wind turbines by 2040!!
Maine government bureaucrats, etc., in a world of their own climate-fighting fantasies, want to have about 3,000 MW of floating wind turbines by 2040; a most expensive, totally unrealistic goal, that would further impoverish the already-poor State of Maine for many decades.
Those bureaucrats, etc., would help fatten the lucrative, 20-y, tax-shelters of mostly out-of-state, multi-millionaire, wind-subsidy chasers, who likely have minimal regard for: 1) Impacts on the environment and the fishing and tourist industries of Maine, and 2) Already-overstressed, over-taxed, over-regulated Maine ratepayers and taxpayers, who are trying to make ends meet in a near-zero, real-growth economy.
Those fishery-destroying, 850-ft-tall floaters, with 24/7/365 strobe lights, visible 30 miles from any shore, would cost at least $7,500/ installed kW, or at least $22.5 billion, if built in 2023 (more after 2023)
Almost the entire supply of the Maine projects would be designed and made in Europe, then transported across the Atlantic Ocean, in European specialized ships, then unloaded at a new, $500-million Maine storage/pre-assembly/staging/barge-loading area, then barged to European specialized erection ships for erection of the floating turbines. The financing will be mostly by European pension funds.
About 500 Maine people would have jobs during the erection phase
The other erection jobs would be by specialized European people, mostly on cranes and ships
About 200 Maine people would have long-term O&M jobs, using European spare parts, during the 20-y electricity production phase.

The Maine people have much greater burdens to look forward to for the next 20 years, courtesy of the Governor Mills incompetent, woke bureaucracy that has infested the state government
The Maine people need to finally wake up, and put an end to the climate scare-mongering, which aims to subjugate and further impoverish them, by voting the entire Democrat woke cabal out and replace it with rational Republicans in 2024
The present course leads to financial disaster for the impoverished State of Maine and its people.
The purposely-kept-ignorant Maine people do not deserve such maltreatment
Electricity Cost: Assume a $750 million, 100 MW project consists of foundations, wind turbines, cabling to shore, and installation at $7,500/kW.
Production 100 MW x 8766 h/y x 0.40, CF = 350,640,000 kWh/y
Amortize bank loan for $525 million, 70% of project, at 6.5%/y for 20 years, 13.396 c/kWh.
Owner return on $225 million, 30% of project, at 10%/y for 20 years, 7.431 c/kWh
Offshore O&M, about 30 miles out to sea, 8 c/kWh.
Supply chain, special ships, and ocean transport, 3 c/kWh
All other items, 4 c/kWh
Total cost 13.396 + 7.431 + 8 + 3 + 4 = 35.827 c/kWh
Less 50% subsidies (ITC, 5-y depreciation, interest deduction on borrowed funds) 17.913 c/kWh
Owner sells to utility at 17.913 c/kWh
NOTE: The above prices compare with the average New England wholesale price of about 5 c/kWh, during the 2009 - 2022 period, 13 years, courtesy of:
Gas-fueled CCGT plants, with low-cost, low-CO2, very-low particulate/kWh
Nuclear plants, with low-cost, near-zero CO2, zero particulate/kWh
Hydro plants, with low-cost, near-zero-CO2, zero particulate/kWh
Cabling to Shore Plus $Billions for Grid Expansion on Shore: A high voltage cable would be hanging from each unit, until it reaches bottom, say about 200 to 500 feet.
The cables would need some type of flexible support systemThere would be about 5 cables, each connected to sixty, 10 MW wind turbines, making landfall on the Maine shore, for connection to 5 substations (each having a 600 MW capacity, requiring several acres of equipment), then to connect to the New England HV grid, which will need $billions for expansion/reinforcement to transmit electricity to load centers, mostly in southern New England.
Floating Offshore a Major Burden on Maine People: Over-taxed, over-regulated, impoverished Maine people would buckle under such a heavy burden, while trying to make ends meet in the near-zero, real-growth Maine economy. Maine folks need lower energy bills, not higher energy bills.
APPENDIX 2
Floating Offshore Wind in Norway
Equinor, a Norwegian company, put in operation, 11 Hywind, floating offshore wind turbines, each 8 MW, for a total of 88 MW, in the North Sea. The wind turbines are supplied by Siemens, a German company
Production will be about 88 x 8766 x 0.5, claimed lifetime capacity factor = 385,704 MWh/y, which is about 35% of the electricity used by 2 nearby Norwegian oil rigs, which cost at least $1.0 billion each.
On an annual basis, the existing diesel and gas-turbine generators on the rigs, designed to provide 100% of the rigs electricity requirements, 24/7/365, will provide only 65%, i.e., the wind turbines have 100% back up.
The generators will counteract the up/down output of the wind turbines, on a less-than-minute-by-minute basis, 24/7/365
The generators will provide almost all the electricity during low-wind periods, and 100% during high-wind periods, when rotors are feathered and locked.
The capital cost of the entire project was about 8 billion Norwegian Kroner, or about $730 million, as of August 2023, when all 11 units were placed in operation, or $730 million/88 MW = $8,300/kW. See URL
That cost was much higher than the estimated 5 billion NOK in 2019, i.e., 60% higher
The project is located about 70 miles from Norway, which means minimal transport costs of the entire supply to the erection sites
The project produces electricity at about 42 c/kWh, no subsidies, at about 21 c/kWh, with 50% subsidies
In Norway, all work associated with oil rigs is very expensive.
Three shifts of workers are on the rigs for 6 weeks, work 60 h/week, and get 6 weeks off with pay, and are paid well over $150,000/y, plus benefits.
If Norwegian units were used in Maine, the production costs would be even higher in Maine, because of the additional cost of transport of almost the entire supply, including specialized ships and cranes, across the Atlantic Ocean, plus
A high voltage cable would be hanging from each unit, until it reaches bottom, say about 200 to 500 feet.
The cables would need some type of flexible support system
The cables would be combined into several cables to run horizontally to shore, for at least 25 to 30 miles, to several onshore substations, to the New England high voltage grid..

Whenever people fear or trust government, tyranny rules. Maine citizens are fed up with this nonsense that continuously hikes energy bills and the government reply is to watch your electric meter and curb your usage accordingly. Climate Alarm, The biggest scam ever!

David,
Installed capacity, MW, has a generating capacity of about 0.50, annual average.
3000 MW installed, gives 1500 MW of generation, annual average.
But floaters are new technology with very long blades, that are known to fail often, so 0.50 is grossly optimistic
During Wind/Solar lulls, which happen throughout the year, and could last 5 to 7 days, the wind output would be about 10% of 0.50 or 0.05, or 150 MW, on average.
The other New England generators and other sources, such as reliable imports, would have to provide the shortfall to meet demand, on a less than minute by minute basis.
That means those fill in sources have to be kept in good order, fully staffed 24/7/365, and have a reliable fuel supply and/or storage.
I have been to the Maine sea shore many times, and often the wind is barely blowing
Where are the meteorological records of the past 10 years to support 0.50?

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/
