What is SWAT?

3

Southwest Area Transmission (SWAT) is a voluntary and open study group comprised of regulators, governmental entities, transmission users, transmission owners, transmission operators, environmental entities, and other stakeholders. The goal of SWAT is to promote collaborative regional transmission planning in the Desert Southwest. http://www.westconnect.com/planning_swat. php

History of SWAT

Utilities have always been engaged in regional cooperation to ensure the reliability

  • f the grid (Western Systems Coordinating Council formed 1967).

In the mid- grid and encouraged formation of regional transmission groups (Southwest Regional Transmission Association formed 1994). Local voluntary study groups formed in Arizona when the Arizona Corporation Commission began conducting Biennial Transmission Assessments in 2000 (e.g. Southeast Arizona Transmission Study and Central Arizona Transmission Study).

  • Organizations. Many planning groups realigned, but RTOs never became
  • mandatory. (SWRTA merged with WSCC in 2002 to form WECC, while

WestConnect prepared to become an RTO in the Southwest) In 2004, CATS expanded its voluntary group to form SWAT. SWAT has coordinated with Sierra Subregional and Colorado Coordinated Planning Groups since 2007 to meet increased FERC regional planning requirements (WestConnect Agreement for Subregional Transmission Planning). SWAT will continue to define its role through the future as regional transmission planning needs change (e.g. FERC Order No. 1000).

Current SWAT Study Work

Arizona Corporation Commission 9th Biennial Transmission Assessment coordination

Some contingency analysis on ten year plan filings Reliability Must Run studies in local pockets

Assisting WestConnect in FERC Order No. 1000 Planning Process

Used SWAT forum to develop a draft power flow simulation case for WestConnect planning study Will use the SWAT forum as needed to review WestConnect study results

Coal reduction study

First phase completed in 2014 Second phase will be completed by January 2016. (Focuses on EPA 111(d) scenarios and identifying conceptual transmission needs to address reliability concerns)

Baseline

Reference case without coal plant shutdowns Simulated a Heavy Summer 2019 condition

Two Scenarios (about 20% coal retirement)

Expected Coal Reduction with Planned new Gas Expected Coal Reduction replaced by Renewables

Two Sensitivities (about 50% coal retirement)

High Coal Reduction with High Renewables High Coal Reduction with Renewables and Planned new Gas

Specific generating units and locations identified to replace retired units to the extent information was available

slide-20
SLIDE 20

20

The High Coal Reduction with High Renewables scenario demonstrated widespread cascading after single contingencies. Other scenarios demonstrated fairly acceptable system performance. There is a limit to the amount of coal plants that may be shut down while maintaining reliable system operation

Unsure of exactly where the limit falls, especially as dispatch scenarios change in different times of the day or year. The limit seems to be influenced the amount of gas fired replacement capacity, which could be due to its reactive power capability. The amount of renewable resources that may be integrated is dependent upon addition of gas fueled generation or other resources that compensate for loss of inertia and dynamic reactive capability No analysis to show what transmission system upgrades could resolve system cascading (e.g. capacitors, synchronous condensers, new transmission lines)

Ongoing studies are needed

How To Get Involved In SWAT

Upcoming quarterly SWAT meetings:

May, webinar August, Westminster, CO November, Phoenix, AZ

Various subcommittee calls/webinars throughout the year (Arizona, Eldorado Valley, New Mexico) Email distribution lists for each of these groups. Contact Patrick Harwood (harwood@wapa.gov)
