AUDIT ENGAGEMENT LETTER
Mike Cunningham, Chair
Bradley Lake PMC - Budget Subcommittee
We are pleased to confirm our understanding of the services we are to provide for Bradley Lake
Project Management Committee for the year ended June 30, 2004.
We will audit the balance sheet of Bradley Lake Project Management Committee as of June 30,
2004, and the related statements of operation and fund balance for the year then ended.
The objective of our audit is the expression of an opinion about whether your financial
statements are fairly presented, in al] material respects, in conformity with generally accepted
accounting principals. Our audit will be conducted in accordance with generally accepted
auditing standards and will include tests of your accounting records and other procedures we .
consider necessary to enable us lo express such an opinion. If our opinion is other than
unqualified, we will discuss the reasons with you in advance. If, for any reason, we are unable.to
complete the audit or are unable to form or have not formed an opinion, we may decline to
express an opinion or to issue a report as a result of this engagement.
Our procedures will include tests of documentary evidence supporting the transactions recorded
in the accounts, tests of the physical existence of inventories, and direct confirmation of
receivables and certain other assets and liabilities by correspondence with selected customers,
creditors, and banks. We will request written representations from your attorneys as part of the
engagement, and they may bill you for responding to this inquiry. At the conclusion of our audit,
we will require certain written representations from you about the financial statements and
related matters.
An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements; therefore, our audit will involve judgment about the number of
transactions to be examined and the areas to be tested. Also, we will plan and perform the audit
to obtain reasonable assurance about whether the financial statements are free of material
misstatement. Because of the concept of reasonable assurance and because we will not perform
a detailed examination of all transactions, there is a risk that material errors, fraud, or other
illegal acts, may exist and not be detected by us. In addition, an audit is not designed to detect
errors, fraud, or other illegal acts that are immaterial to the financial statements. However, we
will inform you of any material errors that come to our attention and any fraud that comes to our
attention. We will] also inform you of any other illegal acts that come to our attention, unless
clearly inconsequential. Our responsibility as auditors is limited to the period covered by our
audit and does not extend to any later periods for which we are not engaged as auditors.

Bradley Lake PMC - Budget Subcommittee
Our audit will include obtaining an understanding of internal control sufficient to plan the audit
and to determine the nature, timing, and extent of audit procedures to be performed. An audit is
not designed to provide assurance on internal control or to identify reportable conditions, that is,
significant deficiencies in the design or operation of internal control. However, during the audit,
if we become aware of such reportable conditions, we will communicate them to you.
We understand that you are responsible for making all financial records and related information
available to us and that you are responsible for the accuracy and completeness of that
information. We will advise you about appropriate accounting principles and their application
and will assist in the preparation of your financial statements, but the responsibility for the
financial statements remains with you. This responsibility includes the establishment and
maintenance of adequate records and effective internal controls over financial reporting, the
selection and application of accounting principles, and the safeguarding of assets. Management
is also responsible for identifying and ensuring that the entity complies with applicable laws and
regulations.
We understand that Alaska Energy Authority will prepare the schedules that we request and will
locate any documents selected by us for testing.
We expect to begin our audit approximately October, 2004 and to issue our report no Jater than
November, 2004.
We estimate that our fees for these services wil! approximate $8,800 for the audit, You will also
be billed for travel and other out-of-pocket costs such as report production, typing, postage, etc.
The fee estimate is based on anticipated cooperation from your personne] and the assumption
that unexpected circumstances will not be encountered during the audit. If significant additional
time is necessary, we will discuss it with you and arrive at a new fee estimate before we incur the
additional costs. Our invoices for these fees will be rendered each month as work progresses and
are payable on presentation.
We appreciate the opportunity to be of service to you and believe this letter accurately
summarizes the significant terms of our engagement. If you have any questions, please let us
know. If you agree with the terms of our engagement as described in this letter, please sign the
enclosed copy and return it to us.
Very truly yours,

BRADLEY LAKE DIGITAL GOVERNOR PROJECT PROGRESS REPORT NOVEMBER 2004
General
After the basic engineering of VA TECH is completed we enter into the detailed engineering phase
with purchasing of additional major components.
Governor and Controls
The governor contro! topology has been finalized and approved. The submitted I/O list has been
updated and will be re-subrmitted by middie of November 2004. The governor electrical design (e.g.
control cabinets, electrical schematics) was revised and re-submitted for approval on November
1st, 2004,
The governor hydraulic schematics for the deflector and needles were revised, re-submitted and
approval! on June 2004,
The existing governor pump unit and accumulator have been revised due to increased deflector
servomotor volume for the Jet divider and submitted in June 2004.
The deflector distributing valve assembly drawings and bill of materials were submitted on
September 2004 and verbally approved.
The VATECH Pelton turbine governor algorithm including the multi-jet control, needle selection and
flow calculations was modeled in Matlab/Simulink and run against a simplified Bradley Lake model.
The results of the most critical base cases are positive. VATECH submitted the modified algorithm
on November 4th, 2004 and is in process of implementing Bradley Lake's specific operation
Interaction through the HMI.
VA TECH Is planning to submit the governor Matlab/Simulink model and related documents by the
end of November 2004.
Turbine Model Test
The turbine model test has been successfully performed during the week of September 6 to 10 at
VATECH laboratory facilities in Zurich, Switzerland. This procedure included the testing with a
model of the existing deflector as well as a model of the new divider.
The model tests were witness by Mr. Donald Stead and Mr. Brian Hickey.
The final report has been submitted with transmittal # 11 in seven hard copies and two back up
CD's.
The test results with the new VA TECH jet dividers showed a substantial improvement of the power
characteristic and a significant reduction of the power oscillations compared with the existing
deflector.
As an immediate result the existing nozzle protection roofs can be reutilized. However, new
protection roofs for the brake nozzles need to be designed, manufactured and installed.

VATEGH)
VA TECH Hydro USA Corp.
The test results with the new VA TECH runner showed a potential efficiency increase between 0.5
and 3.1 % versus the existing Fuji runner. VA TECH will submit a budgetary proposal for
replacement runners by the end of November 2004.
VA TECH experienced substantial cost overrun during the preparation and execution of the model
test as the power oscillation test turned out to be much more challenging than expected. VA TECH
is preparing a detailed cost analysis and will share it with HEA with a request for review and
consideration of cost sharing.
Project Status
VATECH has partially recuperated the time lost during the early stage of the project and continues
to be committed to bring the project back on tract. VATECH will provide a revised schedule by
middle of November 2004 showing the updated project status.
Major Subcontracts
VA TECH extended the Matlab/Simulink governor control algorithm modeling contract with
MottMacDonalds in Scotland to incorporate the addition mentioned above.
The turbine model test has been completed and VA TECH is in process of issuing the
correspondent invoice.
The purchase order with our sister company VATECH HYDRO in Vevey, Switzerland to design,
manufacture and supply the new jet dividers, protection roofs and mounting material needs to be
modified according the results of the turbine model test. The design phase is in process and the
first set of drawings will be submitted by middle of November 2004 and the delivery to site is still
scheduled for middle of April 2005.
Events
The control cabinets factory test, needle valve assembly and divider valves are tentatively
scheduled for January 2005. The contro! cabinets and needle valve assemblies test are going to be
in Charlotte, NC. The jet divider distributing valve test will be performed at VA TECH's workshop in
Ravensburg, Germany.
The final test dates will be coordinated with the customer's representatives by the end of November
2004.

Subject: Follow-up information
The Bradley Lake O&D Committee provides the enclosed follow-up information and recommendations as
requested at the 11-18-04 BPMC meeting.
12/3/2004
The BL O&D committee provides the following in response to requests from the 11/18/04 BPMC
meeting:
1. The committee recommends that the BPMC procure 3 new, non-cast, detuned runners.
The cost of the runners is estimated to be between $1 and 1.5 MM each. Efficiency
gains achieved from 2 new VA Hydro runners would be expected to result in additional
generation valued at approximately $85,000.00 per year according to efficiency and value
estimates.
After a follow-up meeting on December 20", the committee will provide the BPMC with
an additional recommendation whether to bid out or complete an expedited sole source
purchase of the runners. A sole source purchase is being considered by the committee
to expedite delivery. Sole sourcing would be contingent on determining whether VA tech
can provide a suitable runner based on specs being developed, and suitable payment,
delivery, and shipping schedules. Don Stead will inquire with VA Tech and report back to
the committee at the December 20" meeting. A financing mechanism will be suggested
that is consistent with the payment schedule.
2. The committee recommends that the BPMC not pursue manufacturer liability claims
related to Governor or turbine runner problems. Assigning liability at this point in the
project life will be difficult and complex and will likely require litigation for damages with
an uncertain outcome.
3. After a follow-up meeting on December 20", the committee will provide the BPMC with
the risk weighted cost associated with bucket failure as requested. Don Stead will
develop worst, possible, and probable failure case scenarios, Art Copoulos will provide
replacement costs based on original SWEC study, and Brian Hickey will assign
probabilities using an internal CEA model.
4. Interim mitigation measures that will be implemented until replacement runners are
available will include: .
Repair and detune existing spare runner by approximately mid-January
Install repaired spare runner on Unit #2, and repair (cut-out and repair old weld)
and detune existing unit #2 runner.
Based on results, determine if similar repair is justified on unit #1 runner.
Develop and implement procedure for detailed inspection of turbine shaft and
generator during planned summer outage including possible “mag” check.
Continue vibration monitoring.
Continue current inspection program that includes dye penetrant test inspection
after each oscillation or in 3 months whichever is sooner. am 00 @P

Gentlemen:
Mr. Janorschke asked me to forward this update to you.
The Bradley lake unit 2 was shutdown on Saturday May 22" for annual inspection and
maintenance. Visual inspection of the runner found a crack at the root of bucket 9 adjacent to a
previous weld repair. After discussion with Bob Zacharski, the crew removed the runner on May
23", The spare runner was installed in Unit 2 on May 24" and the outage put back on track.
A full dye penetrate check was performed on the runner and no other indications were found. Bob
Milne of Bacon Donaldson in Vancouver, B.C., was contacted. He recommended that a sample of
the crack be removed for analysis. The sample was removed on Tuesday the 26'" and sent to Bob
Milne.
This runner was inspected in October 2003 and no crack was present. There was one event in
November of 2003 that had oscillations.
All three runners have now had cracks and weld repairs. The crack at this location on this runner
was the deepest and the longest.
We await the metallurgic analysis from Bob Milne before we proceed with a weld repair.

MEMORANDUM
TO: Bradley PMC
FROM: Ron Saxton
DATE: March 30, 2004
RE: Bradley Bonds Reporting Requirements and FAS 150
Some of you have asked questions on a variety of subjects having to do with the financial
operations of the Bradley Lake Project. I have decided to address the issues all together and they
are elaborated upon below.
Bradley Bonds Reporting Requirements. I have been asked to provide information on the
Railbelt utilities obligations to report certain information regarding utility finances and
operations under the requirements of the outstanding bonds for the Bradley Lake Hydroelectric
Project. I want to take this opportunity to remind everyone of their reporting obligations, make
sure everyone is doing what they are supposed to be doing and familiarize those of you who may
not already be with the process. It is also to make you aware of recent changes in the law.
All of the Bradley purchasers, except Seward, have had reporting obligations since the
original bond issue in 1989.
The official statement for each bond series lays out the financial reporting requirements
for AEA and the Bradley Purchasing Utilities. Purchasing utilities that fall under the reporting
requirements as stated in the Continuing Disclosure Agreement (see Official Statement, Power
Funding Revenue Bonds, Fourth Series, Bradley Lake Hydroelectric Project, Appendix C)
entered into at the time of issuing the Bradley Bonds, are those who, under the Power Sales
Agreement have purchased 10% or more of the capacity of the Project. Therefore, ML&P,
Chugach, HEA, GVEA and MEA are obligated to make annual disclosure of certain financial
information.
The requirements for the purchasing utilities (I have not included a summary of the
requirements for AEA, but they are somewhat different and are on a different timeline) are
briefly summarized as follows:
The "Disclosure Representative" for the Purchasers, who is the Chairman of the
Bradley PMC (currently Steve Haagenson, GVEA), is required to provide to the
"Dissemination Agent" (US Bank) by 15 days prior to the submission due date (Sept. 30)
an Annual Report that contains the following information for the previous FY:
e Audited financial statements (or, if audited statements are not available, unaudited
ones are acceptable).

Bradley PMC
March 30, 2004
Page 2
e Updated information per tables listed in the Official Statement, e.g, selected
statistics for calendar year; power purchaser’s power requirements; energy loads
and resources; and historical operating results.
FAS 150 — I was asked to look into whether this new accounting standard affects the
accounting practices in place for the Bradley Lake PMC. This new accounting standard requires
companies to account for securities that have mandatory redemption dates as debt rather than
equity on the balance sheet. The standard was adopted as a result of the Enron scandal. This
treatment could have serious repercussions on some companies because among other things, it
could cause a company to be in violation of its loan covenants (debt to equity ratios, which in the
normal course prevent a company from incurring too much debt).We did a little bit of follow up
research and determined that there does not appear to be any additional reporting or accounting
burden on the Purchasing Utilities. Furthermore, we believe that any additional reporting burden
falls on AEA and their accountants as issuer of the bonds. The only Bradley series with
mandatory redemption dates is the Sth series.

Lessons learned
Post weld heat treat is the only way to ensure
weld stresses are relieved
Post weld heat treat of high hardness stainless
steels are difficult to control
Occlusions left in weld will still cause a problem
even if the heat treat is performed well
Any weld repair needs to be watched closely

3. Evaluation of the Necessity for Detuning
\VA TECH HYDRO has internal reguiations in which cases of a bucket resonance a risk could occur and detuning is stringent. The method presumes the knowledge of the natural frequencies. in normal cases an adequate FE- analysis is not available and a frequency measurement by hammering necessary. If detuning is recommended or stringent it has to be proceeded by the internal guide lines. In ether case a measuring protocol is mandatory.

Additional Lessons Learned
+ There is an inherent risk for cracking and rupture at monoblock cast Pelton runners which cannot be reduced to zero, even by consequent application of inspections within rather short periods.
+ Testing also of the back side of the bucket root is essential.
+ Vibration monitoring of the units is highly recommended
+ The experience with MicroGuss over more than 12 years has shown that the risk of cracking is practically eliminated thanks to forging the critical transition zone from the disk to the buckets.
+ No root cracks have been observed in none of the more than 200 delivered MicroGuss runners. MicroGuss allows for a troublefree operation and needs minimum care at doing NDT.
+ By using MicroGuss the inspection periods can be extended by a factor of four.

D, C, and B.
6. APPROVAL OF MEETING MINUTES - January 7, 2004
Mr. Posey moved to approve the meeting minutes of January 7, 2004. Seconded
by Mr. Calvert. Chair Haagenson noted a change on page 2, change SWAG to
estimate. On page 4 of 4, in the second paragraph under Operators Report, the
second sentence should read “An ongoing document control effort is ongoing in
conjunction with Art’s office to categorize and catalog the drawings and
publications associated with Bradley.” A voice vote was taken, and the motion
passed unanimously as amended.

Art Copoulos noted that what the O&D Committee has proposed is to have contingency
money available — a couple of things broke and needed immediate repairs, and we really
didn’t have time to go to the BPMC to get the funds to repair them. What we would like
in the future, is to have a relatively small contingency fund to deal with the immediate
repairs that need to be corrected in the interest of continuing the project operation and
safety. What the O&D committee has proposed is basically a three step process: 1) that
when something is identified that the O&D Committee will review the request and
approve or deny use of the contingency fund; 2) only unbudgeted projects with
immediate operating consequences would qualify for consideration; and 3) the O&D
Committee would present any activity related to that contingency fund at the next BPMC
meeting.
Chair Haagenson stated that it’s also wise to get the O&M Committee involved in some
of these conditions, because there may be more than one solution.
Mr. Carmony stated for the record: “For the same reason as Mr. Zoerb expressed at a
previous meeting, we believe that the firm of AterWynne has an inherent conflict of
interest and we will be voting against the budget if it includes a $40,000 commitment that
would be earmarked for the firm of AterWynne. I’d just like to see it placed in the
minutes in the discussion that we believe that AterWynne has this conflict of interest.”
Steve Haagenson asked if there is a plan to adequately fund the governor replacement
using the R&C fund mechanism, or should we be funding that — what’s the long-term
plan for the R&C fund? The number is $553,596, are we depleting the R&C fund or are
we planning on using it to do these governor repairs, are we going to get bonding to do
that, what’s our plan to do the governor repairs and finance?
Linda MacMillan responded that if you look at Schedule D of the FY05 budget packet,
we did a cash flow of money going in and out of the R&C fund and where it would leave
us based on current plans. She did a recap, based on HEA’s estimates for the governor
work on how much should be paid out of the R&C fund and how much should be coming
out of the construction fund balance.
Mike Cunningham asked that the following be placed into the minutes. “Mr. Chairman,
I'd like to commend Brenda and Linda for their work in pulling this budget together and
arm wrestling with the committee members on the final numbers. They did a great job.”
MOTION #04-7: Mr. Griffith moved to approve the FY05 O&M budget and a
second by Mr. Posey. All members voted aye, with the exception of MEA for the
reasons Stated above. This will be noted in the minutes.
7C. INSURANCE ISSUES Cunningham
Chair Haagenson stated that there is an active proposal in the street, which is pushed
back a little because of the budget process. We are looking at our insurance. One
concern he had was that the person doing the review didn’t think they had access to the
ARECA insurance exchange books. Chair Haagenson would like to see that get
resolved in the near future before it comes out.
Page 3 of 6
@ @ “\)
Mr. Cunningham stated that he would talk to them again and see if there has been any
progress made in that area.
Mr. Saxton asked if there was a deadline for that progress.
Mr. Cunningham responded, stating that we have received the preliminary report and the
Chairman requested that the Budget Committee review the report and given the
deadline on the FY05 budget, we have decided to do the budget work first and are now
going to turn our attention to reviewing the preliminary report and will be getting a
summary and recommendation to the full BPMC within the next month or so.
7B. REFUND OF PRIOR YEAR BUDGET ADJUSTMENT
(continuation/clarification)
Chair Haagenson stated that in the minutes last month, is reference that we were going
to get clarification from counsel on a form for O&D insurance. Mr. Saxton has provided
that. Also, there had been a question about the auditor's opinion about paying back the
money for the Power Sales Agreement and the number that is in the budget is $900,000
and apparently on the audited information it’s about $2 million now.
Chair Haagenson also stated the auditor's report says it’s basically $2.13 million
refunded per the Power Sales Agreement. In the FY04 budget, there is an analysis of
effective amendment of FY04 O&M budget -— the first line says budget effective FY03
surplus refund and it has a total amount refunded of $903,501. It was forecasted FY03
surplus budgeted used in budget preparation. So, that number is now moved from
$900,000 to $2.013 million.
Ms. Applegate explained the dollar amount. When we did the original FY04 budget,
FY03 wasn’t complete yet. Part of our budget preparation is a projection of where we
thought we would be at the end of FY03, and that was the surplus number we rolled
forward. Now that FY03 is complete, our audited financials are done, the number was
really the $2 million dollar number. Our projections during the FY04 budget preparation,
the original budget, were off. The majority of that was due to the R&C fund and us not
spending as much as we thought we would out of that. The true surplus that is going to
be refunded is the $2 million.
Mr. Saxton stated that the most literal reading of the contract if it says at the end of the
year you recalculate and return any surplus, is to write a check and return it. It would be
taking that overpayment from the proceeding year and applying it to the current year
obligation. Once you have finalized determining what that surplus amount is, each utility
will state that they want theirs through a check or would rather have it applied to our
current years obligation.
Ms. MacMillan responded that a check can be sent; however, the checks you pay goes
to a trust account at US Bank. A check on your behalf with your surplus could be sent.
Mr. Posey stated that from an accounting standpoint, it probably is cleaner, and it just
makes it simpler. It may be more difficult for others to get the money to roll back in, but
his auditors are telling him to get a check.

oe
Ms. Applegate responded that the FY04 amended budget that we just approved is
calculated based on us actually writing that check back to everyone now, which is what
we thought we decided at the last meeting.
Mr. Saxton stated that there will be different choices by different utilities. Just be on the
record that you have authorized the return of the annual adjustment, but that each utility
will be notifying AEA how they wish to receive it.
Mr. Calvert stated that the City of Seward would like to roll it over and to consider that
notification.
Ms. MacMillan stated that she will need an email of who wants a rollover and who wants
a check.
8A. Committee Reports / Comments Haagenson
Martin River: Mr. Copoulos discussed the Martin River application. The license
amendment application to FERC was submitted and received approval from the Army
Corps. Preliminary concerns were raised regarding the Fish and Game’s concern about
closing the airstrip according to Federal air regulations, and subsequent conversations
with them indicate that they are okay with what we have proposed. We don’t anticipate
any problems getting this amendment approved through the agencies and through
FERC, and expect to complete this work as proposed in the amendment and according
to the timeline and budget.
O&D: Bob Zacharski reported that there had been a battery explosion at the
microwave site. A new battery bank is on order as a new charger, and spill clean up
should be completed next week. Cable failure happened in late January. They were
able to repair it, and will come back with ideas for re-routing that cable so it is more
accessible for maintenance purposes. Preventative maintenance tasks are on schedule.
They augmented the operations staff at Bradley to get more electrician help at the plant
and clean up the outstanding task under the preventative maintenance.
Chair Haagenson asked about the SVC training. There is a lot of discussion on the level
of training and who is going to be responding and how many people are going to be
training on the top and maintain the SVC. Did that get resolved or did the whole thing go
into the budget unscathed?
Mr. Hickey stated that they have not done major maintenance on the facility since it was
installed. There is a series of major maintenance that has come due, and unfortunately
because they were both installed at the same time, it all comes due at the same year,
give or take 18 months. They have five relay techs and they all get trained and we have
three substation techs and four substation linemen who get trained. They are on a much
larger list.
Mr. Hall also noted that part of this is for ABB to come up and tell us what we need to
look at replacing so we don’t get in a position where we are with the Intertie SVCs. They
will tell us where we are obsolete and what we need to be looking at replacing.
Operator Report: Bob Zacharski reported that they are at 1,128 in terms of water
level.

Governor Replacement: Don Stead reported that the hydraulic transient analysis
has been complete and is under review and the State is hiring a third-party to review the
results. The way it’s stated now, it will need to be increased by 60 seconds from the
current 90 seconds. The change is going to require FERC approval. Change order #1
has been issued to VA Tech, so we got the $100,000 discount. Data collection is in
progress. Model test design is currently in progress, and the factory acceptance test is
projected for July 9" through the 15". New Control Algorithm has been delivered and
the conversion is in progress. The outages are at 35 days each, and probably need to
be increased to 45 days each, and also should be slipped from March into April in order
to accommodate the changes for the jet dividers. The delay is on Change Order #1,
once they complete the model and they develop the model test results, they then have to
go into design of the new jet dividers and design of the shield and the operating
mechanism. That design pushes delivery to the site to April 16", which fits right into the
middle of the second outage. In order to fit it up with that schedule for Change Order #1,
you actually need to slip the outages back into April so the material will be available for
the first unit.
8B. Next Meeting Date
The next meeting will be at the call of the Chair.
