By 2035, the chief automakers will have turned away from the internal combustion engine. It’ll be up to the grid to fuel all those new cars, trucks and buses.
Experts in Scotland found exposure to electromagnetism triggered 'behavioural and physiological responses' in around 60 brown crabs at the St Abbs Marine Station. ...The cables for offshore renewable energy also emit an electromagnetic field that attracts the crabs and causes them to become stationary, which affects breeding and migration, according to the team.
That’s because President Joe Biden wants the country to have electricity with no carbon dioxide emissions by 2035. To reach that, the country would need to more than double the power infrastructure it has now in the next decade, according to a Princeton University study.
The Trustees say that they have demanded that Ørsted delay the cable installation, slated to begin in early 2023, in order to complete a second spring season worth of fish migration surveys. The company has said it will wait to “energize” the cable until after the spring 2023 fishery surveys are conducted, but cannot put off the start of cable installation between the wind farm site south of Block Island and Wainscott. “They were told directly at the time that this would be a deal breaker,” Trustees Clerk Francis Bock said on Monday morning.
While Avangrid has agreed to pay for the upgrade itself, NextEra’s position is that Avangrid should also compensate NextEra for any revenues lost while the Seabrook station is offline to allow the work to happen. In filings it estimated these costs at about $560,000 a day. But Avangrid doesn’t trust its rival not to slow walk the work, especially if there is no net financial cost for it to do so.
The state Senate and Assembly on Thursday approved a bill giving state regulators the authority to seize property or grant easements for transmission lines carrying electricity from offshore windmills to the power grid, even over local objections. The companion bills, S3926 and A5894, authorize “certain offshore wind projects to construct power lines and obtain real property interests; grants BPU authority to supersede certain local governmental powers upon petition from offshore wind project.”
Bonnie Brady, executive director of the Long Island Commercial Fishing Association, said she felt blindsided by the announcement and that there has been minimal communication between Equinor and fishermen. “Why didn’t this process start more organically from the beginning, in a way that actively includes fisherman, so that no one is ultimately put out of business or put into a scenario where they lose traditional historical fishing grounds that are sustainably fished and have been,” she said.
National Grid, encountering unforeseen problems, has suspended work on Block Island to replace part of an underwater cable that delivers electricity from the nation’s first offshore wind farm to the mainland power grid. ...“We need to assess what is causing these obstructions, how best to get the pipe cleared, and ultimately complete the installation with confidence in the fall,” Terry Sobolewski, president of National Grid Rhode Island, said in a statement. “We’d rather get it right in the fall than try to rush completion of it now.”
The Danish wind power firm Ørsted has warned that up to 10 of its giant offshore windfarms around the UK and Europe will need urgent repairs because their subsea cables have been eroded by rocks on the seabed. ...Ørsted has found that the rocks placed at the base of the wind turbine foundations to prevent the erosion of the seabed were responsible for wearing down the cable protection system which, in a worst case scenario, could cause the cables to fail.
Leading offshore wind developer Ørsted has suggested that a scour protection method which left the inter-array cables unstabilised could be the potential reason for an up to DKK 3 billion (EUR 403 million) issue across up to ten wind farms in Europe. As reported earlier, Ørsted first became aware of the problem earlier this year during an inspection after an outage at the Race Bank wind farm offshore the UK.
The company identified a total of 10 projects in the U.K. and Europe that used the same design that may need to be remedied. Some projects will be easy to fix. The company can just dump more rocks on top of the cables to make them stay in place. ...But in other cases, Orsted will have to repair or replace the cables. That’s the pricey option that will make up the bulk of the cost, Wiinholt said.
“To a large extent we will be able to mitigate it through stabilising the cable protection system. It will be done by dumping rocks on top of the rocks that are already there.” At other wind farms, the cables are so damaged that the company will either need to repair or replace them, which is more expensive than dumping more rocks on top of the existing protection layer.
Opponents of the Wainscott landing proposal, led by the Citizens for the Preservation of Wainscott, have presented reams of evidence in support of having the cable brought ashore in Amagansett or Hither Hills instead of in Wainscott. The wind farm developers — the Danish energy giant Ørsted and it’s partner, the New England utility company Eversource — have argued that the Beach Lane landing would be the shortest and least disruptive route between the sea and the East Hampton substation.
Maine's ambitious goal of cutting carbon out of its economy by the mid-21st century is facing a harsh reality: The network of wires and substations built to feed power from central generating stations to homes and businesses isn't up to the job of handling the two-way, intermittent flow of energy from solar and wind farms to electric vehicles, heat pumps and giant storage batteries.
The aim of the Missouri bill to stop the project’s developers, Invenergy Transmission, from pursuing condemnation if landowners won’t sell easements, which means allowing a piece of their land to be used for the power line. Grain Belt developers decried the legislation as short-sighted.
Missouri’s Republican-led state House is trying to ban the use of eminent domain for a large wind-energy power line.
The court granted a temporary injunction sought by opponents ordering the company to stop work on the entirely new section of the proposed line until judges can review a legal dispute related to it. That effectively stopped work on that part of the corridor until the U.S. Court of Appeals for the First Circuit takes further action.
Legislative Bill 409, which also would set up a special Unicameral committee to study transmission-line issues, reflects a years-long Sandhills dispute over Nebraska Public Power District’s currently mothballed R-Project. If passed, the bill would forbid “a public power district, public irrigation district or public power and irrigation district” from starting or continuing construction on transmission lines at least 200 miles long through Jan. 1, 2023.
In court papers Monday, the developer says access road plowing started Monday and construction is expected to begin on or about Jan. 18.
East Hampton Town and the East Hampton Town Trustees this week made public the easement and lease agreements they have negotiated with wind farm developers Ørsted and Eversource for the rights to bury the South Fork Wind Farm power cable beneath a beach and town roads in Wainscott in exchange for nearly $29 million in compensation from the company over the next 28 years.
