Louisiana and 4 different state public service commissions have filed a proper grievance towards the Midcontinent Impartial System Operator, accusing the grid operator of reliance on “patently unreasonable” assumptions to justify $22 billion price of transmission tasks in its long-range planning portfolio.

The grid operator features to coordinate the dependable transmission of electrical energy throughout a number of states by managing energy flows.

In a submitting with the Federal Power Regulatory Fee, the Louisiana Public Service Fee joined commissions from Arkansas, Mississippi, North Dakota and Montana in an accusation of a faulty enterprise case for the nonprofit’s Lengthy Vary Transmission tasks generally known as Tranche 2.1.

Tranche 2.1, which solely contains grid upgrades within the Midwest, will assemble “a 3,631-mile 765 kV and 345 kV spine that ensures future reliability whereas offering advantages that exceed prices,” based on the grid operator.

“The Louisiana Public Service Fee joined the grievance for 2 main causes,” a spokesman for the fee wrote to The Middle Sq. in an e-mail. “First, MISO’s LRTP 2.1 course of is flawed because of the unreasonable underlying assumptions relied upon to justify these tasks as Multi Worth Initiatives, which leads to a broad allocation of prices. As well as, our concern is that, though at the moment there isn’t a allocation of those prices to Louisiana, on account of FERC precedent established within the Sunflower case, Louisiana shouldn’t be assured insulation from an allocation of these prices into the long run.”

“These tasks fail to satisfy the basic requirement of offering advantages equal to or in extra of forecasted prices,” the grievance says.

The grievance says the grid operator overstated financial advantages to push the portfolio’s benefit-to-cost ratio above the 1.0 threshold that’s required.

The grievance asserts that the grid operator added new profit metrics and revised others after its unique modeling failed to indicate advantages exceeding prices. Stakeholders, together with Midcontinent’s Impartial Market Monitor, reportedly raised issues about these assumptions all through the stakeholder course of, however the grievance says these have been “ignored.”

“When the market monitor recognized main defects with MISO’s assumptions, relatively than handle these issues, MISO ordered workers to problem the IMM’s authority,” the grievance states.

Potomac Economics, the market monitor, says the plan possible appears higher on paper than in actuality.

Potomac mentioned Midcontinent made a few assumptions that don’t maintain water, reminiscent of counting further energy vegetation that wouldn’t really be wanted and exaggerating the danger of blackouts, amongst others. Fixing these errors, the grievance argues, would present the plan’s prices outweigh its advantages.

Midcontinent, working throughout elements of 15 states and the Canadian province of Manitoba, pushed again strongly towards the allegations. The grid operator mentioned the “poor and deceptive” grievance threatens to undermine wanted infrastructure and inject regulatory uncertainty into future technology and transmission planning.

Jeremiah Doner, representing the grid operator, rejected the declare that Tranche 2.1 forces states to pay for unneeded tasks, saying the plan was inbuilt collaboration with state regulators and utilities and displays their useful resource plans.

Doner mentioned in his testimony that 93% of the technology in its “1A” deliberate infrastructure upgrades and greater than half in “2A” got here instantly from member-submitted plans, with the remainder added by the operator’s mannequin to satisfy system wants.

“Whereas the LRTP Tranche 2.1 Portfolio is estimated to price MISO members about $5 per 1 MWh or 1,000 kWh of vitality used, that funding will 12 present $10 to $18 of worth over that very same quantity of utilization,” Midcontinent Impartial System Operator mentioned.

The long run planning effort is being rolled out in a number of tranches, with the primary three targeted on the Midwest area. Later tranches will handle the South area and interconnections between the Midwest and South, the place the nonprofit says transmission capability is more and more strained by a surge in renewable tasks searching for interconnection.

The corporate’s South area contains Louisiana, Texas, Mississippi and Arkansas. The Central contains Illinois, Missouri, Kentucky, Indiana, Michigan and Wisconsin. The North contains Iowa, Minnesota, South Dakota, North Dakota, Montana and the Canadian province of Manitoba.
