…MISO’s overlooked least-regrets solutions
Grid Enhancing Technologies (GETs) represent a least-regrets solution for manging rising and changing load from increased electrification because they can be quickly deployed to increase existing wires capacity and meet reliability needs at a fraction of the cost of new wires, Smart Wires General Manager, Americas, Mark Freyman said. And they can be redeployed when reliability challenges emerge elsewhere.
There are four types of GETs, said Grid Strategies Vice President Jay Caspary. Power Flow Control relieves congestion by rerouting electricity flows. Dynamic Line Rating (DLR) allows system operators to use more of the line’s capacity, topology optimization automatically reconfigures system flows, and storage is an alternative to transmission. MISO’s omission of these technologies is a “deficiency,” he said.
GETs, like storage, are important technologies, but they were not included in MISO’s study because it did not consider mitigation strategies, report lead author Brown responded. MISO declined further comment.
“Electrification will require expanding transmission and, until recently, the hundred-year-old model for expansion was building or upgrading lines,” said Hudson Gilmer, Co-Founder and CEO of DLR provider LineVision. GETs “represent a new model for expanding capacity.”
“Ramps and peaks are going to change with electrification,” said Smart Wires’ Freyman. GETs “meet the near-term need by allowing access to underutilized capacity on the system, and when that need is resolved, the hardware can be redeployed to address challenges from new transportation or building electrification load at another location.”
“Utilities are rightfully conservative about protecting reliability, but electrification is part of a historic shift that will require new approaches.”
The ultimate solution for electrification’s risingh and changing loads, peaks, and ramps is new transmission, but it takes time to get transmission projects approved, permitted, sited, financed and built, Caspary said. GETs are readily deployable to allow dispatchers to limit the severity of ramps and the extent of peaks by using more line capacity.
The MISO 2020 State of the Market Report from market monitor Potomac Economics issued in May concluded the changes provided by GETs “will substantially improve the utilization of MISO’s transmission network and ultimately lower the costs to MISO’s customers,” LineVision Co-founder and VP of Products Jonathan Marmillo pointed out. And FERC is working to support wider deployment.
“Utilities are rightfully conservative about protecting reliability, but electrification is part of a historic shift that will require new approaches,” Marmillo added. “GETs are a least-regrets strategy to address uncertainties as they formulate larger planning and will eventually be a part of system planning.”
