Approximately $176 million of debt rated
New York, January 07, 2021 -- Moody's Investors Service, ("Moody's") today
assigns an A1 senior unsecured rating to California Independent System
Operator Corporation's (CAISO) new revenue bond issuance.
The new bonds are industrial revenue bonds issued through the California
Statewide Communities Development Authority as the conduit. The
bonds are senior unsecured obligations of CAISO. Bond proceeds
of about $176 million will be used to defease CAISO's outstanding
revenue bonds issued by California Infrastructure & Econ. Dev.
Bank, its only debt issuance outstanding. The outlook is
stable. See below for a complete list of rating actions.

RATINGS RATIONALE
CAISO's rating reflects the essential and established role it plays
in California's electricity market as the independent, nonprofit
operator of most of the state's high voltage power grid as well as its
wholesale markets. CAISO has the operational control of the transmission
grid within its control area. Its role is therefore literally essential
to keeping the lights on for Californians.
CAISO's financial stability is critical to the functioning of the
grid. For physical power to be delivered within its control area,
the delivery must be scheduled in combination with a trade with the ISO.
The ISO is the central counterparty to all the 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.
CAISO has a stable source of revenue. CAISO adds a grid management
charge to market participants on each trade to cover its costs,
which include operating costs, capital costs, debt service,
and reserves. Since 2004, the grid management charge has
been established via a FERC formula subject to specific revenue requirement
caps for varying periods of time.
CAISO has a strong financial security for its financial obligations because
it has a first priority claim on the market revenues that are deposited
into its clearing accounts. In the event that a market participant
defaults on its payment obligation or fails to pay its grid management
fee, the ISO can first draw on the collateral provided by the defaulting
counterparty, and if needed, from the market clearing account.
The loss is then socialized to non-defaulting participants.
The ISO's adjusted CFO pre-WC to debt has averaged about
26% for the past three years (2017-2019) and we expect the
ratio to be maintained above 20% on a run-rate basis.
Liquidity
CAISO's liquidity is comfortably buttressed by a large amount of unrestricted
cash holdings and a first priority claim on market revenues.
Even though CAISO does not have any external revolving credit facilities,
it maintains a large unrestricted cash balance (over $200 million
in 2018 and 2019). In comparison, according to its 2021 budget,
CAISO's entire revenue requirement is only about $181 million.
CASIO has a large unrestricted cash balance because cash reserves for
capital expenditures, operating expenses, debt service and
other expected liabilities are considered to be unrestricted cash.
If necessary, these reserve accounts may be accessed for any of
CAISO's liquidity needs.
CAISO also has a first priority claim on its market clearing accounts.
However, we expect the CAISO to access market revenues only as a
last resort and only in case of an emergency.
CAISO does not have any major upcoming debt maturities because it only
has amortizing debt.
Rating Outlook
The stable outlook reflects our view that CAISO will continue to play
an integral, essential and effective role in California's energy
markets, and that its established rate-setting policies and
first priority claim on market revenues will remain in place and sustain
its credit quality.
Factors that Could Lead to an Upgrade
- Increased diversification, for example as a result of material
expansion to regions outside of California's service territory.
- A material improvement in the credit quality of the state's
investor owned utilities
Factors that Could Lead to a Downgrade
- In the unlikely event there were to be successful challenges
to the CAISO's essential role in the state's electric industry
- If an unanticipated departure of a significant member permanently
and materially impacts revenues and debt service coverage
Company Profile
CAISO is a nonprofit public benefit corporation incorporated in May 1997.
It is responsible for the operation of long-distance, high
voltage power lines throughout most of California that also deliver power
to and from neighboring control areas and states, along with Canada
and Mexico. CAISO offers open access to the transmission system
through a market for electricity and related services, thereby fostering
a competitive wholesale marketplace. CAISO's all-time
system peak load record of 50,270 MW was set in July of 2006.
