What the document says

PDF p. 21

LARS and the queue use different assumptions, so both can claim the same headroom.

LARS projects will therefore be studied as if the only other generation on the system is generation that already holds a GIA. PDF p. 21

PDF p. 21

Queued generators say overallocation raises their upgrade costs and curtails their output.

resulting in more constraints and higher Network Upgrade costs for DPP projects when they are finally studied against a system that LARS projects have already used. PDF p. 21
Filed comments: Cost allocation

PDF p. 6

Utility gatekeeping of LARS applications is undue discrimination against independent generators.

LARS is unduly discriminatory because it makes the LSE the gatekeeper of a Commission-jurisdictional generator interconnection process PDF p. 6
Filed comments: Connecting load and generation

PDF p. 2

LARS is a permanent, uncapped fast lane untethered to any identified resource adequacy need.

It is permanent and uncapped. It is untethered to any identified resource adequacy need. PDF p. 2
Filed comments: Reliability and curtailment

PDF p. 27

Unlike ERAS, LARS has no cap, sunset, independent-producer carve-out, or regulator check.

LARS contains no scoring criteria, no carve-outs, no regulatory verification, no cap, and no sunset. PDF p. 27

PDF p. 14

Same-LRZ pairing is not the two-substation test the Show Cause Order described.

LARS does the opposite: it grants permanent NRIS through a parallel process PDF p. 14
Filed comments: Connecting load and generation

PDF p. 24

Clean energy groups say LARS adds a fifth path onto the grid and breaks planning.

MISO has now twice prioritized separate, one-off expedited processes that not all market participants can feasibly access on a comparable, not unduly discriminatory basis PDF p. 24

PDF p. 29

ACP and SREA: MISO has not met the independent entity variation standard.

MISO cannot satisfy the independent entity variation standard, and LARS does not accomplish the purposes of Order No. 2003 PDF p. 29

PDF p. 30

Protesters ask FERC to reject LARS outright; Clean Energy Advocates offer a deficiency letter instead.

the Clean Energy Trades respectfully request that the Commission reject MISO's LARS proposal. PDF p. 30
Filed comments: Connecting load and generation

PDF p. 30

If FERC accepts LARS, ACP wants the same-LRZ test applied at the point of interconnection.

the relevant location is the applicable POI to the MISO Transmission System rather than the physical location of the Generating Facility PDF p. 30

Responses and related views

MISO says independent generators can negotiate before applying

Midcontinent Independent System Operator · Direct response

MISO said the transmission customer submits an application for an already matched pair. It argued that an independent generator remains free to bring a proposal to that customer before the application, and that the eligibility rules are nondiscretionary.

A. MISO’s Initial and Revised ERAS Proposals

printed heading · Topic match: Reliability and curtailment

The accepted ERAS process is capped at 68 interconnection requests, with ten reserved for IPPs that have agreements with entities other than LSEs and eight reserved for requests serving retail- choice load; it requires verification by a Relevant Electric Retail Regulatory Authority (“RERRA”) of a…

C. The LARS Proposal

printed heading · Topic match: Connecting load and generation

The LARS Proposal MISO proposes LARS as a new, permanent study process under which a large load of at least 200 megawatts (“MW”) and one or more new Generating Facilities are studied in parallel, with the generator receiving a Large Load Generator Interconnection Agreement (“LLGIA”) for NRIS in…

PROTEST Because MISO filed LARS under FPA section 205, MISO bears the burden of demonstrating that its proposal is just and reasonable and not unduly discriminatory or preferential.23 MISO has not carried that burden.

LARS studies “will not include Interconnection Requests currently in the generator interconnection queue that do not have an executed GIA.”84 LARS projects will therefore be studied as if the only other generation on the system is generation that already holds a GIA.
