Power cable proposal connecting offshore wind runs afoul of Long Island fishermen

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.

Ørsted says offshore UK windfarms need urgent repairs

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.

Ørsted points to possible reason for EUR 403 million cable problem

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.

Cable failures hit offshore wind farms

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.

Damaged offshore wind cables to cost Orsted almost half a billion dollars: CFO

“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.

State could approve wind farm cable landing on Thursday

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.

Costly power grid upgrade to boost renewables will test Maine's commitment

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.

Gordon senator introduces bill that makes it harder for power districts to build long transmission lines

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.

Wind farm agreements released, hearings scheduled for January

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.

Transmission grid bottlenecks in Northeast Kingdom stall solar development

In the Northeast Kingdom, the electric grid is out of balance. Several big local wind and hydro projects, plus power imports from Canada, mean the wires carry much more power than the region can consume. The imbalance has caused the regional grid operator to reduce the output from the wind generators. It's also led to the de-valuing of local generation and a two-year moratorium on new renewable projects in the Kingdom.

Vineyard Wind Secures Transmission Agreement With ISO-NE

Vineyard Wind has announced a transmission agreement with ISO New England (ISO-NE) to deliver power to the system operator’s grid when the Vineyard Wind 1 project comes online. The 800-MW offshore wind farm, located about 15 miles off the cost of Martha’s Vineyard in Massachusetts, is expected to be the first commercial-scale offshore wind farm in the U.S.

Ratepayers on hook for portion of Block Island wind farm cable mess

National Grid, which owns the high-voltage power line from Block Island to Narragansett, expects to pay $30 million for its share of the reconstruction, which will require horizontal directional drilling. The state’s primary electric utility will recover the expense through an undetermined surcharge on ratepayers’ bills. ...The power line from the five-turbine Block Island Wind Farm reaches shore at Fred Benson Town Beach and leaves New Shoreham for Narragansett at Crescent Beach to the north. But keeping portions of the cable buried at Crescent Beach has been a struggle.
