Rating Action Affects Outstanding $1.7 Billion Revenue Bonds
New York, December 05, 2013 -- Moody's Investors Service has affirmed the A1 rating on the American
Municipal Power Inc. (AMP) outstanding $1,696,800,000
Prairie State Energy Campus Project Revenue Bonds, Series 2008 A,
2009 A, B and C and Series 2010 A. The outlook is stable.
Rating Rationale:
The A1 credit rating rests on the strong bond security which includes
the unconditional take-or-pay obligation of 68 municipal
project participants in the Prairie State project to pay O&M and debt
service on the bonds. The Prairie State Project is a 1629 MW coal-fired
generation facility that went commercial in 2012. The obligation
of the AMP participants is an unconditional obligation provided for in
state statutes regardless whether the project operates or not.
AMP's Prairie State municipal utility participants were compliant
with their legal obligations in 2012-2013.
The average weighted credit quality of the participants is A2 with the
numerous participants spread across a large geographic area. The
service area economy of the participants has generally rebounded since
the recession, yet demand growth is slower than what had been projected.
Electric loads are back to 2007 levels with energy efficiency programs
also having an impact on demand growth. The rating also considers
the important role AMP Inc. (A1 issuer rating , stable) plays
in power supply including the successful implementation of its fuel diversification
strategy and for its provision of other energy services to municipal participants.
Both units of Prairie State went commercial in 2012, at a lower
capacity factor than had been originally projected due to a mechanical
issue impacting Unit 2. The delay in commercial start up sparked
some customer criticisms since debt service was being paid prior to any
energy being received. Since the units went into commercial operation,
they have subsequently operated at a lower capacity factor of about 66%
,as start-up issues such as tube leaks and boiler issues
are being worked out. This "shake-out period"
is typical for a major new power plant in the first year of operation
and the capacity factor is close to industry experience for first year
of a coal plant's operation. The impact of less generation
versus budget on current retail rates of participants was minimized by
use of available unspent funds applied to participant billings in 2013.
The AMP Inc. board also approved a Rate Stabilization Plan for
FY 2013 -2014.
Should Prairie State not meet its objective of higher than an 80%
capacity factor after the planned Spring 2014 outage, this would
be a significant credit pressure. Moody's believes,
however, that Prairie State management has a defined proactive plan
to improve plant performance and progress is being made towards that end.
A slag issue and a boiler improvement project to fine tune the combustion,
air flow, pressures and temperatures are being resolved and have
recorded progress. Management projects an 81.7% capacity
factor in 2014.
A negative development also has been the impact of changes in the Midwest
ISO market since Prairie State was under construction. Locational
congestion pricing in the Midwest ISO market has added new costs to the
Prairie State generation output. As performance of the two coal-fired
generation units improve, projected congestion pricing will add
additional costs to the transmission of the energy into the Midwest ISO
market. The estimated impact is about a $5/Mwh higher price
of energy. AMP Inc. and the other Prairie State project
owners are looking at various alternatives to mitigate this new pricing
issue.
Moody's believes that the value of the long term asset remains favorable
as a source of long-term stable capacity for the participants.
The plant enjoys a very competitive onsite 30-year supply of coal
reserves and level debt service which equates to a stable capacity price
for an extended period. This could be a particular advantage as
energy and capacity markets change as a result of industry developments
such as the shutdown of older coal-generation; pricing of
carbon through regulation; and stronger economic trends. See
Moody's special comment "Prairie State Coal-Fired Generation
Project: An Economic Asset Which Should Support Owner's Willingness
to Meet Obligation to Bondholders" published December 2012.
The participants have a diverse power supply mix with Prairie State coal
generation representing on average about 16% of their peak load
requirement. Some participants have higher percentages in the 20%
range. AMP's coal-fired generation is well below the
region's average reliance on coal and Prairie State represents the
most advanced technology; has the most stringent environmental standards
and is among the newest units constructed. AMP reports that Prairie
State is fully compliant with the MACT rule and will be considered as
an existing plant for the Mercury and Air Toxics rule. The EPA
is expected to introduce a greenhouse gas emissions output restriction
for existing coal-fired generating units in 2014. Without
advancements in carbon capture and control technology, at this point
it is unlikely that plant specific restrictions are possible given the
state and cost of the technology. Absent carbon pricing the worst
case could be EPA regulation that would reduce output of coal-fired
generating units which could present challenges for Prairie State as well
as other coal-fired units in the Midwest.
AMP supplies most participants with a broad set of power supply sources
including through owned hydro and gas fired generation and through power
market purchases. This power resource diversity is a positive credit
consideration. AMP's participants have a competitive advantage
with their retail rates being lower than neighboring utilities largely
due to the overall competitive wholesale power rates charged by AMP.
OUTLOOK
The rating outlook is stable given that both units are commercial and
participants are being billed for their respective shares of O&M and
debt service. The strong take-or-pay contracts also
lend credit stability. Failure to improve the two coal-fired
generating units capacity factors after the Spring 2014 outage to average
above 80% would result in downward rating pressure.
What Could Change the Rating UP:
The rating could be upgraded should the all-in costs of Prairie
State improve relative to regional comparable energy prices, and
project participant credit quality improves.
What Could Change the Rating DOWN:
The rating could be downgraded if any participant successfully challenges
through litigation their take-or-pay Prairie State supply
contract that are the underpinning of credit quality. The rating
could also be downgraded should AMP Prairie State participant credit quality
weaken. Also downward rating pressure would develop should the
Prairie State production cost rise significantly and impact retail electricity
prices or should the two units not reach a capacity factor above 80%
in 2014.
CREDIT STRENGTHS:
*Take-or-pay contracts with municipalities with a weighted
average credit quality of A2
*Power supply contract for 50-years by members to join the
Prairie State Project indicates strong support for AMP's role as a regional
power supplier
*Several Prairie State enhancements not originally incorporated in
the budget are estimated to have substantial long term savings including
power plant output improving to above nameplate capacity; reduction
in transportation costs due to ash disposal site being located closer
to plant; and larger permitted cuts in mine which improves mining
efficiency.
*The Prairie State Project has several unique advantages including
a prepaid coal supply that should be relatively stable in price;
adjacent location of coal reserve and mine near coal-fired generation
facility which eliminates rail transportation risk; and advanced
environmental controls which meet current standards for pollution control
and are designed to emit less carbon
*Competitive current and projected member retail rates
*AMP has a well-regarded fiscal monitoring system to provide
ongoing assessment of members' credit profiles including evaluation of
financial metrics
*Coal as % of AMP energy mix is about 25% versus about
75% in Ohio
*Limited deregulation risk at retail level for municipal electric
utilities
CREDIT CHALLENGES:
*No assurances that environmental regulation will remain the same.
Any federal legislation that addresses greenhouse gas emissions could
have an adverse impact on the cost of coal-fired generation
*Some of the smaller participants have questioned the higher than
projected cost per Mwh of Prairie State. Requests for an Ohio State
Attorney General investigation has not resulted in any review of the power
sales contracts those participants entered into prior to project construction
*Regional energy prices have fallen due to the decline in natural
gas prices. To the extent natural gas prices remain low and drive
the regional energy price, this is a pressure.
*Federal regulation of carbon as a greenhouse gas and under the Clean
Air Act subjects all coal-fired generation facilities with the
specter of future regulations that could reduce the economics of this
generation. While Prairie State is in a favorable position due
to the strong environmental attributes for the facility, it remains
subject to potential further regulation.
*First year of operation capacity factors ranged well below forecast
in the 60% range due to boiler issues.
*Changes in the Midwest ISO market since Prairie State was under construction
include locational congestion pricing. As performance of the two
coal-fired generation units improves, projected congestion
pricing will add additional costs to the transmission of the energy into
the Midwest ISO market. The estimated cost is about a $5/Mwh
higher price of power.
