DearMs. Salas:
On December 26,2000 the Federal Energy Regulatory Commission (Commission)issued an Order Amending License that approved a turbine upgrade at the Holt Project,FERC ProjestNo. 2203.
Paragraph (C) of the Order required the Alabama Power Company (Licensee) to"install a new nameplate on the generator to indicate the 46,000 kW capacrty of thegenerator as if it were operated at a power factor of 1.0. A new nameplate for the turbineshall also be installed to indicate the capacity described in paragraph B of the order.Within 30 days of installation of the nameplateq the licensee shall provide photographsof the nameplates to the Commission, and the Commission's Atlanta Regional Office, forverification."
The initial start-up of the Holt unit, following the upgrade outage, was attempted onMarch 15, 2001. Shottly after the unit was placed in service, there were obviousperformance problems. Vibration levels were high, and power output was well belowexpected levels. After a short period of rough operation, a steel dowel pin dropped fromthe upper bearing bracket, and lodged in the rotor fan blades. The pin severely damagedthe insulation on the stator coils, rezulting in a shutdown of the unit. An inspection wasconducted, and it was decided the stator coils would have to be replaced. Both partiesagreed the first priority was to return the unit to service, and to delay any discussion ofcommercial and contractual responsibilities until later.
Following the replacement of the stator mils, and other required repairs to the statoriron and rotor poleg the unit was restarted on August 3,2001. The unit continued toperform well below expectations, which was confirmed by a field performance testconducted on August 30, 2001. The contractor then began an investigation into theperformance problems. This was a lengthy process involving the installation oftemporary equipment at the plant, laboratory testing at the contrsctor's facility, andvarious tests being conducted at the plant.
In January 20A2, field rnodifications were conducted by the contractor to re-profilethe bottom ring and discharge ring. This was a tedious process, requiring a 2}-dayout4ge to accomplish the modifications. '
On February 7, 2002, the unit was restarted and performed very well. All theprevious operational problems had been rectified and all performance guarantees weremet. This was officially confirmed by a February 28,20A2, field perforrrance test. Oncethe unit was in service and operatrng acceptably, the process of negotiating the damagesbegan. This involved numerous correspondence being exchaqged, and internaldiscussions and meetings with legal council. f,)uring this period, all remaining oroutstanding project matters, which included nameplate discussions, wetre placed on hold.A final letter of settlement was signed by both parties in December 2002.
The process of requesting, reviewing, rwising and approving draft nameplates wasvery slow following the agreement process. It has taken the majority of 2@3 to obtainboth nameplates. The generator nameplate had to be re-ordere4 due to a problem withthe GE procurement syster4 and was finally received at Holt Dam on October 2,20f-3.On October 6,2003, the generator and turbine nameplates were installed. Auached arepictures ofthe installed nameplates, rellecting the post-outage capacities.
Also enclosed is a performanc€ summaf,y of the upgraded unit detailing thecalculation of the installed capaclty. The Licensee respectfully requests that theCommission incorporate this as-built installed capaclty, which would revise partgraphT.B(ii) ofthe license, in part, to read as follows:
"(ii) Project works consisting of a power installation to be constructedconcurrently with the proposed United States Holt l,ock and Darq which willcreate a reservoir of approximately 3,200 acres at elevation 186.5 feet, toinclude an intake structure located at the right end of the spillway, a power-house containing a 66,410 horsepower turbine operating under a gross head of60 feet and connecaed to a 46,94 kilowatt gen€rator, a zubstatioq a tailrace,and a transmission line to the Holt zubstation; and other appurt€nant facilities;the locatioq nature and charact€r of which are more specifically shown anddescribed by the exhibits which also formed part of the application for licenseand which are designated and described as follows: . . ."

The following are the new performance parameters for the Holt unit:
Turbine Rating (klV) GeneratorRating (kW)
Holt unit | 49,807 46,944
Both the generator and turbine ratings were calculated at the maximum efficiency outprrtfor the unit. The formula used for calculating generator and turbine ratings is iheCommission's authorized installed capacity equations from the Code of FederalRegulations.
Generator - The rating of the generator is the product of the continuousJoad capacityrnting of the generator in kilovolt-amperes (kVA) and the system power factor inkwlkvA.
Turbine - The rating of the turbine is the product of the turbines capacity in horsepower(hp) at best gate (maximum ef;Eciency point) under the manufasturer's rated head times aconversion factor of 0.75 kWlhp.
Authorized Installed Capacity * The lesser of the ratings of the turbine and generatorunits ofthe hydro project.
The turbine has the lesser rating for the upgraded unit. The new Authorized InstalledCapacity for the Holt unit is:
