Land-use actions for projects
Chugach has several land-use actions underway or pending to enable future projects –
or in one case, to remedy an adverse result of a prior project. Chugach has been discussing
the following projects with neighborhood councils, municipal officials and others.
Chugach is seeking to rezone its 44-acre headquarters complex from I-1 to I-2 in advance
of construction of the Southcentral Power Project. Chugach has operated a gas-fired power
plant on the site since 1964, but if the Assembly approves proposed changes to Title 21 the I-2
zoning would be preferred. The Planning & Zoning Commission approved the change on April 5. It
will also go before the Assembly.

The Southcentral Power Project will be built on land Chugach is currently using for activities,
which will be moved to a recently purchased parcel of land between the headquarters parcel and
Minnesota Drive. One of the things that will need to move is the helipad where crews needing to
patrol or access remote parts of the system are picked up and dropped off by Chugach's contracted
helicopter service. This summer Chugach will be submitting a conditional use permit application
for the proposed new helipad site.
Meeting Schedule:

Since the 1990s, Chugach has owned four vacant lots adjacent to the Girdwood Substation. This
summer Chugach will seek a conditional use permit for three of the unused lots to accommodate
improvements to the substation, including the installation of new switchgear.

Abbott Area Substation
Chugach has made an offer to purchase a 2-acre lot for a new substation, provided it can secure
conditional use of the property for that purpose. The land is on the south side of O'Malley Road
east of Lake Otis Parkway. An application for a conditional use permit is expected to be submitted this summer.
Chugach's offer to purchase the property along O'Malley Road for a substation site is conditional.
These conditions include passing an environmental screening, being found to be geotechnically
appropriate for the intended use, and Chugach securing a conditional use permit to use the property
as the location for a substation. Under the terms of the purchase agreement, Chugach has 6 months
to complete all necessary actions or the sale can be cancelled.
Meeting Schedule:
| April 15, 2010 | Huffman/O'Malley Community Council |
| April 29, 2010 | Abbott Loop Community Council |

Chugach is still working with the Municipality of Anchorage on a solution for land lost at the
Dowling Substation to a recent road project. Chugach is seeking an equal amount of land to enable
future improvements to be made at the substation, located near the intersection of Dowling and Elmore roads.
Girdwood Substation Upgrade
Chugach operates a substation on lots 17 and 18, Block 3, Girdwood Original
Townsite. This substation has been in operation since the early 1970s. Plans for
an expansion of this station in the 1990s led to the purchase of Lots 19 to 22
adjacent to, and north of the existing station. The upgrade plans were postponed,
when the availability of natural gas slowed the growth of demand for electric
energy in the community.
Condition and age of equipment installed in the station now make it necessary
to replace the low voltage (25kV) open-air switchgear as well as the control
enclosure. In order to accommodate future load growth and increase service
reliability, Chugach plans to install 25kV switchgear in a metal enclosure,
which will provide capacity for 2 transformers, 3 feeders and a bus tie. It
will also include the controls for the high voltage (115kV) switchgear and
other auxiliary equipment, such as batteries, chargers and low voltage power
panels. Locating the new enclosure on the site made it necessary to determine
future development of the high voltage (115kV) connections.
Load forecasts indicate that a second transformer will need to be installed
between 2020 and 2025. At that time, the existing high voltage switching arrangement
will not be adequate to maintain reliable service. It will be upgraded to allow
termination of a looped 115kV circuit with a circuit breaker to separate line
sections and taps to 2 transformers. This will occupy most of 5 (Lots 17 to 21)
of the 6 lots. In preparation for this expansion, Chugach will clear and fence the
area needed for the final build out at the time the 25kV switchgear is installed. A
wooden fence and planting of shrubs on the exposed sides of the station will enhance
the appearance.
The present zoning of the additional area required for the full build out of the
substation is gC-3, which allows the substation upgrade under a conditional use permit
issued by the Municipality of Anchorage.
In 2009 Chugach evaluated alternative sites for a substation. In early 2010
Chugach presented the results of that study to the Girdwood Board of Supervisors.
Chugach is seeking a Conditional Use Permit for the project on land it owns
adjacent to the existing substation.

| Submit Conditional Use Permit Application | July/August 2010 |
| Receive Conditional Use Permit | October 2010 |
| Procure Equipment | 2011 |
| Construct Upgrade | 2012/13 |
Chugach has determined its least cost resource plan is to build new, more-efficient
generation to replace its existing less efficient, aging generation. The Municipality
of Anchorage d/b/a Municipal Light & Power (ML&P) also desires new, more-efficient
generation. When compared with the costs to design, construct and operate smaller, separate
plants, economies-of-scale can be achieved through the joint construction and operation of a
larger, single plant capable of producing the new generation collectively required. Therefore,
Chugach and ML&P plan to jointly build and own approximately 180 to 270 megawatts of new
more efficient, combined-cycle generation. The new plant (the Southcentral Power Project,
or "SPP"), the "Project", would be located adjacent to Chugach's existing International Station
at 5601 Electron Drive in Anchorage, Alaska.

Projects in the Distribution Facilities Undergrounding Plan 2011 - 2015
On March 1, 2005, the Anchorage Assembly adopted certain revisions to
Section 21.90, Utility Distribution Facilities, of the Anchorage Municipal Code.
These revisions required an electric utility to "include as part of its annual
capital improvement plan, a five-year undergrounding program". In each of the
years of this program the electric utility shall plan on expending "at least two
percent of a three-year average of its annual gross retail revenues derived from
utility service connections within the municipality". This requirement means
that Chugach Electric Association (Chugach) is required to spend approximately
$3.2 million annually to underground existing overhead facilities. Over
expenditures or under expenditures may be carried over as an adjustment to the
following year's obligation.
In the development of the five-year undergrounding program the electric utility
is allowed to choose which existing lines to underground. Specifically, priorities
for the program "shall be based on undergrounding in conjunction with the
utility's essential system improvements and then by target areas".
The following document contains Chugach's five-year undergrounding program.
Overall, the plan calls for $15,569,365 to be expended on undergrounding
existing overhead lines from 2011 to 2015, for an average of $3,113,373
annually.
The projects were chosen taking into account Chugach's overall system needs
and consideration of the designated target areas. The inclusion of a project
within this plan does not guarantee that the project will be constructed in the
designated year.

South Anchorage Loop
The South Anchorage Loop refers to a series of projects Chugach undertook to
strengthen the regional transmission system and provide more reliable power for
South Anchorage. The overall scope of the project entailed construction of a new
transmission substation in South Anchorage (Retherford), and completion of transmission
line segments to link it with Chugach's two existing transmission substations
(International and University).
University Substation to Retherford Substation 138-kV line
A 138kV transmission line will be constructed to link the Retherford
Substation south of Dimond Center with the University Substation south
of Tudor between Elmore and Boniface. The line will be routed along O'Malley
Road between the Alaska Railroad and Elmore Road to connect with an existing
138-kV line that runs north and south along the Elmore alignment.

Abbott Area Substation
Chugach plans to build a new distribution substation at a site to be determined to serve the
growing electrical needs of customers in this area of southeast Anchorage. This project is
scheduled for 2010.
