With the rise in Electric Vehicles’ availability in Midwest states, it’s time to acknowledge the alternatives for charging EVs at MISO, the regional grid operator. MISO has a longtime transmission planning course of for incorporating future business developments, together with EV development. The regional grid operator estimates each electrification and EVs add virtually 50% to the annual power and peak demand forecasts within the subsequent 20 years. And transmission homeowners see this as a possibility to construct extra transmission, nonetheless it’s essential to do not forget that aggregated EV generally is a distributed power useful resource (DER).

MISO and different grid operators can allow EV prospects by permitting aggregated EVs to take part within the power markets. This weblog is a component 2 of three articles that ought to make a case as to why EV prospects are trying brighter within the Midwest, even when any one of many Midwest states is just not California.

MISO 2021 plan estimates a 50% enhance in demand and power attributable to electrification and EV load by 2040

The MISO Transmission Expansion Plan (MTEP) 2021 was put collectively earlier than the November 2020 U.S. Presidential elections. This timeline is related as a result of essentially the most carbon-free future MTEP 21 contemplated goals for 50% penetration throughout the area for photo voltaic and wind power. But because the Biden administration took over in January 2021, it’s affordable to count on MISO planning assumptions to alter and make this aggregative case virtually a base case going ahead.

MISO, Lawrence Berkeley National Laboratory (LBNL), and advisor Applied Energy Group estimate 32.686 million EVs (together with heavy-duty) on the street by 2040 within the Midwest. As one would count on, a big share of this estimate assumes EV development from states like Michigan, Minnesota, Wisconsin, with the least share from southern states like Arkansas.

MISO is rethinking transmission value allocation

MISO has began a Long-Range Transmission Plan (LRTP) course of to include siloed transmission planning akin to generator interconnection, reliability, financial venture, and coverage planning. Let’s take a look at what transmission tasks turn into eligible by way of the LRTP course of, and the way these venture prices can be allotted.

Currently, MISO transmission venture prices are allotted based mostly on the recognized want on the system. If there’s a reliability want, the incumbent transmission proprietor is allotted these prices, who get well these prices from transmission clients. If there’s an financial want akin to transmission congestion, your entire regional load by which the venture is positioned pays.

It is unlikely that aggregated EVs would drive the necessity for a big financial transmission venture resulting in cost-sharing throughout a number of utilities. Most probably, EVs would drive the necessity for a reliability venture.

MISO utilities can combination EV load like DR applications

A key distinction with California is, not one of the MISO states aside from Illinois enable third-party aggregators. As a consequence, aggregated EV operators are the distribution utilities.

And aggregated EVs are just like a requirement response program. Both utilities and the ISO have quite a lot of working expertise with DR and different demand-side applications. And MISO states the place we will count on a surge in EV development attributable to democratic governor’s insurance policies are additionally states which have essentially the most expertise with DR applications.

MTEP22 would present some tasks

MISO churns out an annual transmission growth plan. The schedule laid out proper now could be December 2022, when the MTEP displays these new EV assumptions. It could be fascinating to see which transmission tasks would present up on the system beneath this electrification and EV state of affairs.

MISO Board would approve MTEP21 in December 2021. This plan would probably present a necessity for giant 345 kV aggressive transmission as a result of, in 2017, MISO had a aggressive venture referred to as Hartburg-Sabine, a 500 kV line within the East Texas portion of MISO.


In this weblog posting, a robust case is made for why EV prospects are trying up given MISO transmission planning assumptions. In the following and closing half three weblog,…
