New York, January 29, 2021 -- Moody's Investors Service, ("Moody's") today
affirmed the Electric Reliability Council of Texas, Inc.'s
(ERCOT) long-term Issuer Rating of Aa3. The rating outlook
is stable.
RATINGS RATIONALE
"ERCOT's rating reflects the essential and established role it plays
in the Texas electricity market as the independent, nonprofit operator
of most of the state's high voltage power grid as well as in its wholesale
markets", said Toby Shea, Senior Credit Officer.
ERCOT has operational control of the transmission grid within a control
area covering most of the state. Its role as the independent system
operator (ISO) is therefore literally essential to keeping the lights
on for 90% of the population in Texas.
ERCOT's financial stability is critical to the functioning of the power
grid as ERCOT is the central counterparty to all market participants.
Wholesale market participants, including generators, load-serving
entities and intermediaries, rely on the ISO to not only transmit
the power, but also to collect payments from buyers and make payments
to sellers.
ERCOT has a stable source of revenue from a system administration fee
it charges to market participants on each trade to cover its costs,
which include operating costs, capital costs, debt service,
and reserves. Since 2016, ERCOT's system administration
fee has been established at $0.55/MWh, which has been
sufficient to cover these costs. ERCOT's budget is authorized
by the ERCOT Board and the Public Utility Commission of Texas (PUCT) once
every two years.
ERCOT is protected against counterparty defaults because it is allowed
to socialize any credit loss among its market participants. In
the event that a market participant defaults on its payment obligation
or fails to pay ERCOT's system administrative fee, the ISO
can first draw on the collateral provided by the defaulting counterparty,
and if needed, collect any shortfall from all other non-defaulting
market participants, as a part of its right to socialize any credit
loss.
As a result of ERCOT's stable revenues, low costs and minimal
debt, its adjusted CFO pre-WC to debt has averaged about
100% for the past three years (2017-2019) and we expect
the ratio to be maintained at around or above 100% on a run-rate
basis.
Liquidity
As of 31 December 2019, ERCOT's liquidity position was robust and
included approximately $973 million of cash and cash equivalents
on hand, consisting primarily of amounts held by ERCOT on behalf
of market participants for congestion revenue rights and settlement obligations.
Congestion revenue rights are a financial instrument that allow market
participants to hedge geographic basis risk. This amount is the
equivalent of about 5 years of the ISO's revenue requirements and
excludes approximately $503 million of additional cash it held
as collateral security.
Although ERCOT's cash consists almost entirely of cash that is due to
market participants, ERCOT's Board has adopted standards that allow
the use of congestion revenue right funds, which constitute the
vast majority of cash on hand, to fund ERCOT's working capital
and capital expenditure needs within certain guidelines. In a default
situation, ERCOT could withhold all funds due to market participants
from these accounts to pay itself first. As a result of these provisions,
ERCOT generally seeks to maintain its own operating cash at or near zero.
ERCOT also has access to a $100 million bilateral credit facility
that terminates on 31 December 2024. The credit facility contains
a covenant requiring the company to maintain a minimum debt service coverage
ratio of 1.1 times, which it is in compliance of, and
also requires a representation of no material adverse change (MAC) for
new money borrowings. The requirement for a MAC representation
at each borrowing is very unusual for such a high credit quality company
and increases the risk that the credit facility may not be available when
the company's liquidity needs are greatest, which we view as a credit
and liquidity weakness.
Rating outlook
The stable rating outlook reflects ERCOT's essential role in the Texas
electric industry and its proven cost recovery process, strong revenues,
low costs, and limited debt, which we expect to continue.
FACTORS THAT COULD LEAD TO AN UPGRADE OR DOWNGRADE OF THE RATING
Factors that could lead to an upgrade
While limited near-term prospects exist for the rating to be upgraded,
upward pressure on the rating could develop if ERCOT's rate approval
process were to become more formulaic, including for example automatic
adjustments for variations in volumes or revenue requirements.
Factors that could lead to a downgrade
The rating could be lowered if liquidity becomes constrained or if regulatory
oversight jeopardizes management's ability to establish rates in a manner
that provides sufficient coverage of expenses and debt service.
Profile
Established in 1970, ERCOT is a Texas membership-based non-profit
corporation governed by a 16 member board including both stakeholders
and unaffiliated directors (who are approved by the PUCT). The
company serves to ensure a reliable, and open access, transmission
network on a system that encompasses about 75% of the land area
(90% of the electrical load) of Texas including over 46,500
miles of transmission lines and serving more than 26 million consumers.
