As Arkansas' congressional delegation stepped up its war Tuesday on a $2.5 billion wind-power transmission project, Clean Line Energy Partners has confirmed that it has shelved plans to string the controversial power line across Arkansas. Michael Skelly, the company's president, told Arkansas Business that the direct-current project, which would have transmitted 4,000 megawatts of renewable energy from Western Oklahoma to eastern Tennessee, is basically on life support.
The findings regarding interregional transmission projects are supplements to CAISO’s 2016-2017 transmission plan, which was approved by the ISO’s Board of Governors last year. A second study released Jan. 5 looked at the impact of gas generator retirements scenarios, finding flexible capacity shortfalls at certain times.
The deal was sealed after it became apparent to Clean Line that TVA had little appetite to complete a six-year-old memorandum of understanding to purchase the project’s wind power. Late last year, just weeks after TVA said it was still studying whether to sign the contract, agency President Bill Johnson said the Clean Line project didn’t make economic sense, given TVA’s flat demand and ample generating capacity.
The nation's biggest wind generator, NextEra Energy Resources, has bought the Oklahoma portion of the proposed 700-mile-long Plains and Eastern Line to serve Oklahoma and Midwest customers. But for now, plans to bring wind energy from the windy areas of Oklahoma and Texas into the less-windy Tennessee Valley and Southeastern part of the United States are stalled and unlikely to be resurrected for years.
The 8.6-mile line would cross farmland and forestland, drawing opposition from landowners in its path who worry about impediments to agriculture and logging. Opponents argue that a new transmission line between Tillamook and Oceanside isn’t justified by actual electricity demand, but may instead be intended as a connection to future wave power or offshore wind energy projects.
A Missouri Courts of Appeals is being asked to find a peer court’s decision involving an electric line project erroneous that subsequently was used to deny necessary permits for an even more controversial electric project — the Grain Belt Express.
“There is no way any power transmission line coming out of the Panhandle is going to miss important prairie chicken habitat because the best prairie chicken habitat in Oklahoma is in Beaver County. There’s just no way to miss it,” she said. “It is an issue, but right now our main concerns are the bats and destroying their (hibernation area), the erosion it could cause and the idea of building a power line across this area with all these sinkholes.”
Sen. Tom Brewer plans to introduce a bill next legislative session to place a two-year moratorium to block wind development in the Sandhills. “There's a mad rush right now to build wind turbines in the Sandhills and common sense cannot put a corner-post line and not have put in a dead man to anchor it," Brewer said. "So why would you build a 5,60-foot tower in sand and not question the wisdom behind that?"
If implemented, the proposal would require wholesale power prices to reflect the small amount of electricity lost during transmission through heat or other factors, which would essentially raise the cost of sending power from remote generation plants — such as wind farms — to cities. Transmission losses currently are omitted from prices.
Staff advisers at Oregon's utility regulator threw cold water on PacifiCorp's plan to spend $3.5 billion, one of its biggest upgrades ever, on wind turbines and a new transmission line. The Public Utility Commission staff say the utility had failed to justify the need for the massive capital investments, whether to meet its capacity, energy or reliability needs.
Representatives of five transmission projects proposed in July in response to the Massachusetts solicitation for 9.45 TWh/year of hydro and Class I renewables (wind, solar or energy storage) tried to explain why their projects should be among those selected in January. Contracts awarded under the MA 83D request for proposals are to be submitted in late April.
Energy Secretary Rick Perry on Friday ordered FERC to rescue at-risk nuclear and coal generation by ensuring they receive “full recovery” of their costs.
MISO policy studies engineer Jordan Bakke said the evaluation will first model current renewable penetration — about 8% of the resource mix. It will then examine growing system complexity in increments of 10% renewable resource penetration ...At each 10% checkpoint, MISO will assess systemwide ramping capability, operating reserves, transmission congestion, voltage and frequency stability, and loss-of-load expectation, among other data.
William Shay, the lead attorney for the alliance, said the court agreed with the Illinois Landowners Alliance, Farm Bureau and ComEd on the definition of public utility. "The Court noted that nothing stops Rock Island (Clean Line) from seeking to develop its project as a private facility, but it will not have public utility status, including the right to condemn landowner easements through eminent domain," he added.
Massachusetts’ demand for clean energy has drawn interest from several companies hoping to win lucrative contracts to transmit wind and hydro power from Maine, Atlantic Canada and Quebec. The utilities National Grid, Eversource and Unitil, along with the Massachusetts Department of Energy Resources, are considering dozens of bids, including Maine-based proposals that would entail overland transmission lines and at least two undersea cables running through the Gulf of Maine to the Bay State.
The late-session plan to restructure management of the California power grid skidded to a halt Wednesday in the wake of growing opposition from interest groups and a spate of negative publicity.
Utility companies and the California Independent System Operator, which operates the state's electric grid, say changing from independent oversight of the power system to regional oversight will increase efficiency and help expand clean energy.
Roughly nine months after their decision effectively hampering a proposed wind farm project in Rush County, the Rush County Board of Zoning Appeals will again decide on a permit application from the company working on that project.
In issuing the order, commission members said in part that the company had failed to prove that it had first obtained all necessary consent from counties along the project’s proposed route for road crossings. The PSC cited a Missouri Western District Court of Appeals decision in a separate, but recent, case pertaining to a proposed transmission line in northeast Missouri with regard to obtaining county-level permission.
Most members of Missouri’s regulatory panel said they, too, wanted to approve the high-profile project but felt compelled to vote against it because of a recent state appeals court ruling. The judges in that case said utilities must first get the consent of counties to string a power line across roads before state approval can be granted.
