I consulted with Kevin before I took the oars in trying to answer your
question, as well as the questions raised in Drew's e-mail. Here's what we
found out...

Steve's question:

What economics would determine if a developer could site a power plant in New
Mexico (maybe 3,000MW) and build a line to the grid in California versus us
expanding to deliver the gas to a power plant in California?

What you're really asking here is "What are the comparative economics of
energy delivered by wire versus energy delivered by pipeline?" In this
analysis, there are a few considerations -- (1) original capital cost to
construct facilities, (2) the operating cost of the facilities, including
energy loss, and (3) environmental and other permitting considerations.

Engineers tell us that, as a rule of thumb, high voltage transmission lines
and tower facilities cost approximately $800,000 to $1MM/mile to construct
turnkey. This figure is comparable to the $1MM/mile "rule of thumb" we use
for turnkey construction of mainline diameter (30-36") high-pressure steel
pipeline.

In terms of operating costs, for anything over 100 miles in length, there are
three (3) basic sources of energy loss in electric transmission: (1)
transformation loss, (2) radiation loss (EFM) and (3) heat loss across the
conductors. A rule of thumb for electric transmission loss is 3%. This
number is comparable to the actual fuel used for compression on
Transwestern's pipeline.

The most critical issue impacting construction of high voltage transmission
lines is in the area of permitting. There just aren't many new transmission
lines being approved. It was suggested by more than one source that an
electric transmission project on the order posited in your example, could
take anywhere from 6 to 10 years to secure authorization. The issues of
electromagnetic field (EMF) radiation around high voltage power lines, along
with other wildlife endangerment concerns, are significant obstacles in
securing permits for right-of-way.

In short, the answer is that while the economics on face appear to be
comparable for construction and operation of both natural gas pipelines and
electric transmission lines, the protracted permitting process for electric
transmission lines tips the scale considerably towards the more immediate
returns available on investment in natural gas pipeline infrastructure.


Drew's questions:

1. What are the key factors that determine where a power plant developer puts
his plant?

For purposes of this exercise, I'm assuming we're talking gas-fired
generation. Developers generally describe four considerations in deciding
where to site a new electric power plant:
1. Market area demand (distributive) and/or Transmission access to market
2. Water rights for turbine cooling
3. Ease of permitting (environmental, encroachment, fed/state/local
regulations, affected agencies/jurisdiction)
4. Proximity to natural gas pipeline/supply infrastructure


2. Do the transmission access and pricing rules of the various
utilities/power pools vary all that much or are Order 888 tariffs pretty much
the same all over?

FERC Order 888 and 889 require public utilities to commit to standards of
conduct and to file open access tariffs affecting transmission among and
between other utilities and/or power pools in the various operating regions.
FERC ordered public utility transmission owners to provide transmission
access and comparable service to competitors and to functionally separate
their transmission/reliability functions from their wholesale merchant
functions. The rulemaking is analogous to the open access requirements under
FERC Order 436/500/636 affecting interstate natural gas pipelines. It's
pretty obvious from the California example this past summer, that with
respect to the overall operation of a deregulated power market in individual
states, particularly as concerns the establishment and regulation of
Independent System Operators (ISO's), there is substantial room for
improvement (and possible further FERC involvement).

"In the open access final rule (Order No. 888), the Commission issues a
single pro forma tariff describing the minimum terms and conditions of
service to bring about this nondiscriminatory open access transmission
service. All public utilities that own, control, or operate interstate
transmission facilities are required to offer service to others under the pro
forma tariff. They must also use the pro forma tariffs for their own
wholesale energy sales and purchases. Order No. 888 also provides for the
full recovery of stranded costs--that is, costs that were prudently incurred
to serve power customers and that could go unrecovered if these customers use
open access to move to another supplier."


3. How do IPP's decide what fuel supply strategy works best (i.e., buy
bundled delivered fuel from someone vs. buy gas, storage, transport, etc.
separately)?

In my experience, there is no "one size fits all" formula or strategy. For
example, in the past we've seen Calpine take a very hands-on approach to
supplying its IPP projects. In the mid to late '80's, during the build out
of several QF's (cogens), Calpine bought natural gas reserves in the ground
and dedicated them to the project. In today's market, Calpine has scavenged
the gas and basis traders from Statoil and set-up a natural gas desk for the
purchase and transportation management of gas supplies needed for its western
U.S. power projects. In other projects, developer/owners and their lenders
are satisfied with a less active role in securing gas supply/transportation
to the project. In short, projects look at the liquidity of the gas supply/
transportation market in deciding whether they can achieve project economics
and secure reliable supply by taking bids or RFP's for gas
supply/transportation, or whether to take a more hands-on approach ala
Calpine.


4. What is the RTO Rule and why should we care?

Last December, the FERC issued Order No. 2000, a final rule on Regional
Transmission Organizations (RTO's). Order 2000 builds on the foundation of
Orders 888 and 889 (issued in 1996). According to FERC Chairman Jim Hoecker,
Order 2000 makes "a persuasive case for separating control of grid operations
from the influence of electricity market participants." Therefore, Order
2000 can be seen as a natural outgrowth of the perceived limitations on the
functional unbundling adopted in Orders 888 and 889, continuing balkanization
of the electric transmission grid based on corporate, not state or regional
boundaries, as well as pressure to provide guidance on acceptable forms of
privately-owned transmission companies.

FERC prescribes a voluntary approach to RTO participation. The order
initiates a regional collaborative process to foster RTO formation. The
Order also imposes filing requirements on the privately owned "public
utilities" that are subject to FERC jurisdiction, and requires these private
utilities to describe in their filings how they have attempted to accommodate
the needs of transmission owning state/municipal, cooperative and federally
owned systems. FERC believes that, regardless of format, RTO's will offer
the following benefits: (1) alleviate stress on the bulk power system caused
by structural changes in the industry, (2) improve efficiencies in
transmission grid management through better pricing and congestion
management, (3) improve grid reliability, (4) remove remaining opportunities
for discriminatory practices, (5) improve market performance, (6) increase
coordination among state regulatory agencies, (7) cut transaction costs, (8)
facilitate the success of state retail access programs, and (9) facilitate
lighter-handed regulation.

Critics point out that with its emphasis on flexibility, voluntary RTO
formation and transmission rate reforms (i.e., incentives), Order 2000 defers
for case-specific disposition many of the tough issues that must be resolved
in order to create an operational RTO. Moreover, Order 2000 does not compel
any transmission owner to join an RTO, but provides only regulatory guidance
and incentives for willing participants, as well as a veiled threat of
further consequences for the hold-outs.

As to the final part of the question ("why should we care?"), presumably, the
development of a fully-functioning RTO network will promote both the
efficiency and market transparency goals of the original FERC orders. As
FERC reads it, the future of gas-fired generation for both merchant and
utility systems, depends on an efficiently operated open access transmission
system. Therefore, the promise of the RTO is to stimulate competition and
the ongoing investment in new generation infrastructure. Unfortunately,
sources tell me that the voluntary nature of the RTO program may ultimately
cripple its effectiveness in meeting its stated goals.


5. Has $5/mmbtu gas killed the gas fired power market?

Natural gas prices of $5/MMBtu can only "kill" gas-fired power plants in
those instances where (1) there are more economical alternatives to natural
gas fuel, (2) demand for electric power is offset through demand side
management or (3) natural gas in an environment of short supply is expressly
prohibited from use as a power plant fuel. In the Western U.S. marketplace,
particularly in California, I see no viable alternative to natural gas fuel
for electric power generation. Renewable resources currently meet less than
5% of the total electric resource requirements. $32/barrel oil prices give
fuel oil no clear economic advantage over natural gas (even at a $5/MMBtu
price). Moreover, California environmental and permitting regulations make
the installation of new electric generation based on anything other than
natural gas fuel or renewable resources virtually impossible. While demand
side management programs are the politically correct approach to meeting
resource needs, historically, they have served only a minor role in
offsetting the growth in electric power. As to the final point, I'm unable
to comment on the risk of future legal/regulatory restrictions governing the
use of natural gas as a boiler or turbine fuel.

Since you are the "expert" in this area, I need to know what economics would
determine if a developer could site a power plant in New Mexico (maybe

deliver the gas to a power plant in California. If you could let me know by
next Friday I would appreciate it.

When we originally decided to use my staff meetings for "graduate education"
one of the hot topics was the electric industry. We all had a first lesson
on this topic in Shelley's electricity seminar last summer. Now, John and
Kevin have graciously agreed to join us Tuesday at 1:30 to discuss recent
developments in electric markets and NN's and TW's efforts to attract power
generation load to the system. Specific topics I hope to cover include the
following:
1. What are the key factors that determine where a power plant developer
puts his plant?
2. Do the transmission access and pricing rules of the various
utilities/power pools vary all that much or are Order 888 tariffs pretty much
the same all over?
3. How do IPPs decide what fuel supply strategy works best (i.e., buy
bundled delivered fuel from someone vs. buy gas, storage, transport, etc.
separately)?
4. What is the RTO Rule and why should we care?
5. Has $5/mmbtu gas killed the gas fired power market?
Depending on how deeply we get into these topics, we may need to schedule a
follow-up session at a later date. I look forward to seeing you on Tuesday.
