King (hereafter, `King ") plant in Oak Park Heights to significantly reduce air emissions from this facility. MERP reflects our commitment to providing reliable energy to customers while reducing the environmental impact of generating that power. The package of additions and improvements at King, valued at $382 million, will be completed over the next three years. The scope of the project is to add emission control equipment and rehabilitate existing electric generation equipment to return the King plant to its original design capacity. The new air quality control system includes selective catalytic reduction for nitrogen oxide (NO control, flue gas scrubbers for control of sulfur dioxide (S02 ) emissions, and fabric filters for control of particulate matter. With these modifications, the King Plant will reduce current annual air emissions by the following amounts: The rehabilitation also includes steam turbine replacement, steam generator repairs and modifications, circulating water system modifications, coal handling upgrades, auxiliary electric system upgrades, and other equipment rehabilitation to extend the life of the plant, making the emission control upgrades cost - effective. Additional information on the scope of the project is included in Attachment 1. 1 Xcel Energy June 8, 2004 King Rehabilitation Project Details Scope of Work The scope of work for the King Plant includes the introduction of emissions reduction equipment as well as replacement and modification of existing equipment to extend the life of the plant at approximately its original capacity. See Attachment 1 for scope details. Schedule The strategic planning for the King Plant portion of the MERP began in October, 2003 and the entire scope of work will be completed in June of 2007. Please see Attachment 2 for a schedule of the project milestones, including engineering and construction. Construction Personnel At the peak of construction activities, there will be approximately 300 employees, contractors and trade personnel working at the King Plant. Some of these will be directly contracted by Xcel, others will be subcontracted through construction contractors and vendors whose scope includes erection of new equipment. Parking We estimate that we will need and provide approximately 300 temporary parking spaces to accommodate the peak workforce for this project. Please see Attachment 3 for the conceptual parking arrangement. Lighting Plan Lighting added for this project will be in accordance with city standards and requirements. Tree Protection and Replacement It is our intention to minimize the project's impact to the tree population on the King site. But, while we don't anticipate having to remove "significant" trees — as defined by the City of Oak Park Heights' "Landscape Guidelines for Developers" (3/1/2002) — some impact may be inevitable. We will work with you at a future date to mitigate any impact.

Haar Executive Secretary Minnesota Public Utilities Commission 121 Seventh Place East, Suite 350 St. Paul, MN 55101-2147 RE: SETTLEMENT AGREEMENT EMISSIONS REDUCTION PROPOSAL DOCKET No. E002/M -02 -633 Dear Dr. Haar, 414 Nicollet Mall Minneapolis, Minnesota 55401 -1993 on behalf of Northern States Power Company d /b /a Xcel Energy, the Minnesota Department of Commerce, the Office of the Attorney General — Residential Utilities Division, the Minnesota Pollution Control Agency, Minnesota Chamber of Commerce, Northstar Steel, Izaak Walton League of America — Midwest Office, Minnesotans for an Energy - Efficient Economy, Suburban Rate Authority and the Sierra Club (collectively, "Parties"), please find the attached Settlement Agreement proposed for the Commission's consideration and approval in this docket. The Parties recommend that the Minnesota Public Utilities Commission approve the Proposed Plan filed by Xcel Energy on July 26, 2002 in this proceeding, subject to the terms of this Settlement Agreement. The Parties agree that the Plan achieves significant environmental benefits that are not otherwise required by law at a cost that is significant but not unreasonable, consistent with the requirements of Minn. Stat. 216B.1 692. Specifically, the Commission can find that the Plan and the rate rider, subject to the terms of the attached Agreement, meet the requirements of Minn. Stat. 216B.1692, subd. 5. Under this provision, the Commission may approve a rate rider that: (1) Allows the to recover the costs of gurak:fti7ag emissions reduction projects net of revenuer attributable to the project. Provision 23 of this Agreement provides a mechanism and requirements for crediting revenues to the rate rider in compliance with this requirement. (2) Allows an appropriate return on investment associated with qualz:fiing emissions at the level established in the public utility's last general rate case. Provisions 8 - 12 address rate of return, providing, among other things, a sliding-scale approach to encourage effective management of Plan implementation. This incentive return is an important provision for ensuring the overall reasonableness of the costs of Plan. (3) .Allocates pr ject costs appropriately between wholesale and retail customers. Provision 16 provides for appropriate jurisdictional allocations. (4) Provides a mechanism for recovery above cost, ifnecessay to improve the overall economics of the qualiffing pr jects to ensure implementation. Provision 9 addressing Construction Work in Progress provides for recovery of the return on CWIP during the construction period of the Plan. This treatment provides for recovery of costs in a way different than traditional ratemaking. Given the magnitude of the Plan and the length of the construction period, this treatment of CWIP is needed to ensure implementation of the Plan. (5) Recovers costs from retail customer classes in proportion to class energy consumption. Provisions 31 and 32 address rate design and satisfy this requirement. (6) Teminates recover once the costs of the qualz:fiing projects have been frilly recovered. Provision 28 provides the elimination of the rate rider in the first rate case after all three plants have come into service. The statute further provides conditions under which the Commission may not approve a rate rider, including whether the project is required by law or as a part of any corrective action. Such conditions do not apply to the Plan, as evidenced by the December 29, 2002 Report of the Minnesota Pollution Control Agency. Finally, the statute provides that Commission may not include in the rider any costs that are not directly allocable to the reductions of emissions. This requirement likewise does not apply to the Plan. The Minnesota Legislature removed any ambiguity on this point with its passage of 2003 Laws of Minnesota, First Special Session, Chapter 11, Article 3, Sec. 12 at 1687 -88, which states that all costs related to the Company's primary proposal in this proceeding are eligible for recovery through the rate rider. This Agreement provides rate terms that protect ratepayers while facilitating implementation of the Plan. Subject to these terms, the Plan and rate rider meet the statutory requirement of achieving significant environmental benefits with consumer costs that, while significant, are not unreasonable. The Parties thus recommend that the Commission approve the Plan, subject to the terms of this Agreement. The Parties look forward to presenting this Agreement to the Commission. We are available to respond to any questions the Commission or its staff may have. We appreciate the Commission's consideration of this Agreement, and look forward to resolution of this proceeding. (612) 330-6125 Attachment c. Service List AQCS EQUIPMENT UPGRADES ATTACHMENT 1 KING PLANT REHABILITATION PROJECT SCOPE OF PROJECT This project focuses on reducing emissions and sequentially refurbishing the existing plant equipment for additional life at a capacity similar to the unit's original design rating. Emissions reductions will be achieved by means of air quality control system (AQCS) equipment consisting of a selective catalytic reduction ( "SCR ") reactor for control of NO emissions, a spray dryer absorber ( "SDA ") lime -based semidry flue gas desulfurization ( "FGD ") system for control of SO, emissions, and a pulse-jet cleaned fabric filter ( "PJFF ") for control of particulate matter. The boiler, turbine, and other balance of plant systems will be repaired or replaced as necessary to extend their useful life and support the operation of the new AQCS equipment. The plant will be modified in accordance with the scope of work described herein. The Sections that follow describe the major aspects of the project. While this document outlines many specifics of the project, it is not an exhaustive list of all details. The limits of the scope of work will be as defined during detailed design. The scope of work to be conducted on each of the components and /or systems discussed herein is assumed to include all work (design, manufacturing, fabrication, delivery, installation, and commissioning) necessary for reliable and efficient operation of a full and complete installation in accordance with all applicable local, state, and federal codes and regulations. The new AQCS equipment for the rehabilitated steam generator will consist of a SCR reactor for control of NO emissions, a lime -based semidry FGD system for control of SO, emissions, and a PJFF for control of particulate matter. NO„ Control The flue gas leaving the economizer section of the steam generator will be directed to a new SCR reactor. The SCR reactor includes the reaction vessel, support structure (including foundations and /or piling as may be required), access platforms, walkways, stairs, and lighting. The SCR system consists of an ammonia injection grid ( "AIG ") located upstream of the reactor SCOPE OF PROJECT King Plant Rehabilitation Project Page 2 of 7 and two or more layers of titanium- vanadium - tungsten based catalysts located inside the reactor. Ancillary equipment includes catalyst change out handling equipment (lifting devices and their controls, as well as support structures) and reagent (ammonia) receiving, handling, storage, preparation, and delivery systems. Existing Electrostatic Precipitators Pending results of a condition assessment of their internal components, the existing ESPs are intended to be re -used with minor upgrades. Required modifications include installation of equipment necessary to improve electrical sectionalization, replacement of existing discharge electrodes and their support system with a current rigid discharge electrode design, and stiffening of the ESP shell as required for the balanced draft conversion. SO and Particulate Matter Control The flue gas leaving the ESPs will be directed to two 50 percent capacity semidry FGD absorber modules and one 100 percent capacity PJFF. Lime slurry may be combined with a slurry of recycled solids from the fabric filter to form the reagent slurry. The reagent slurry is injected in the absorber where the lime reacts with the flue gas SO The reaction products, unreacted reagent, and fly ash suspended in the gas stream are then collected by the fabric filter. The PJFF is a multicompartment fabric filter using tubular filter bags to remove the FGD byproducts and fly ash from the flue gas. Each compartment contains several hundred individual filter bags. The clean flue gas leaving the fabric filter is directed to two new induced draft fans. The flue gas is then sent to the two inlet breechings of the existing chimney. Scope of work includes design, fabrication, and installation of spray dryer absorbers, fabric filters, lime systems (receiving, storage, handling, preparation, and delivery), reagent slurry (preparation, storage, handling, and delivery), and scrubber by- product (transportation, storage, handling, and shipping) systems. SCOPE OF PROJECT King Plant Rehabilitation Project Page 3 of 7 Balanced Draft To accommodate the additional draft requirements resulting from the installation of the SCR and AQCS equipment, the unit will be converted to balanced draft operation. The unit would be converted to balanced draft operation by installing ID fans and making the appropriate changes to the steam generator and connecting ductwork. Balanced draft modifications include the design, fabrication, delivery, and installation of Induced Draft fans, motors, foundations, controls, dampers, inlet and discharge ductwork, and electrical supply equipment. STEAM TURBINE GENERATOR The existing steam turbine generator is the unit that was originally installed when the plant was constructed. The existing steam turbine and the existing exciter have reached the end of their respective useful lives, and will be replaced. The existing generator will be re-used. Steam Turbine replacement scope includes entire new High Pressure, Intermediate Pressure, and Low Pressure sections; foundation modifications as necessary to receive the new machine; new steam chest, control valves, and EHC (electro-hydrau]ic control) system, as well as piping replacements, additions, or modifications as required to connect the new turbine to the existing HP steam system. The new Exciter will be of a brushless design. STEAM GENERATOR The existing steam generator (boiler) is a supercritical, constant pressure, cyclone -fired unit designed by Babcock & Wilcox ( "B &W ") and put into operation in 1968. The steam generator MCR was reduced due to a switch to low sulfur coal in the 1970s. Several options to return the boiler to its original design steam flow have been proposed. The following work is currently contemplated: replacement of the furnace floor and support system, replacement of the studded portion of the lower furnace sidewalls, installation of new cyclone burners and re- entrant throats, stiffening as may be required by the Balanced Draft conversion, installation of new secondary air dampers, installation of a rear wall arch, and potential addition of reheat and /or superheat surface as may be necessary to control steam temperatures. Dismantling of the SCOPE OF PROJECT King Plant Rehabilitation Project Page4of7 lower portions of the furnace will necessitate temporary relocation and /or permanent modification or replacement of the existing bottom ash slag tank and handling system. BALANCE-OF -PLANT EVALUATION The major balance -of -plant ( "BOP ") equipment was reviewed to determine which components will require repairs or replacement as part of the rehabilitation. Key portions of the balance of plant scope of work to be conducted are as follow: Auxiliary Power System Portions of the existing plant electrical system will be inspected, cleaned, and repaired as required for long -term reliable service. Portions of the system will be refurbished and upgraded with new solid -state protective relays. The Main Transformer outlet connection to the plant substation will be relocated; relocation to include replacement of towers and conductors. Additional 115 kV to 4160 volt substations, motor control stations, and other electrical equipment will be required to power the new AQCS, SCR, Cooling Towers, and Balanced Draft equipment, controls, and related devices. Verification of the electrical system capacity and condition will be required during detailed design when all new loads have been confirmed. Distributed Control System A microprocessor-based Distributed Control System ( "DCS ") will entirely replace the existing plant control system. An Emerson `ovation' system will replace the existing Bailey Net 90' controls. ovation is the standard DCS system within the Xcel coal plant fleet. The DCS will include control, information, and historian functions, as well as performance monitoring and cptimization functions. Cooling Tower and Circulating Water System The current cooling water system is a once-through system with inlet and discharge canals. The plant heat rejection scheme is to be studied as part of the environmental permitting process. It is likely that a hybrid system will result. The anticipated hybrid system Coal Handling system Scope of work includes a comprehensive study of existing equipment and systems. Improvements will address operating efficiency and control /reduction of ground level fugitive dust. SCOPE OF PROJECT King Plant Rehabilitation Project Page 5 of 7 would provide operation in two modes: `once Through' cooling, as currently configured, and `Closed Loop' cooling using newly installed mechanical draft cooling towers. Scope of work will include design, fabrication, and installation of new mechanical draft cooling towers and basins, modification and /or replacement of existing circulating water piping; modification, relocation, and/or replacement of the existing circulating water pumps; and modification or replacement of the intake screens. Potential modification of the inlet and discharge canals may include design, fabrication, and installation of weirs and/or gates for closed loop operation. Final configuration details are pending based on the terms of the water -use permitting process. Cold Reheat (CRH) piping The Cold Reheat (CRH) piping is a section of the high - energy steam piping system connecting the boiler and the turbine. The existing CRH pipe has reached the end of its metallurgical life, and will be replaced. Scope of work includes design fabrication, and installation of pipe, hangers, anchors, attachments, instrumentation (pressure, temperature, and flow), insulation, and lagging. Other Balance -of -Plant Equipment and Systems Following is an indicative listing of other systems and equipment that will require inspection, rehabilitation, or replacement. Additional details will be developed during detailed engineering design. Ash Handling system The existing Ash Handling system will be modified as required to integrate its operation SCOPE OF PROJECT King Plant Rehabilitation Project Page 6 of 7 with the newly installed scrubber by- product handling system. High - energy piping and hangers In addition to the CRH work described above, the balance of the high energy piping systems will be inspected, adjusted, repaired, or replaced as necessary to insure reliable operation. Feedwater system In addition to the inspection, adjustment, repair, or replacement of the feedwater piping, pumps and drives, and heaters, the #15B heater has reached the end of its useful life, and will be replaced. Condensate system Auxiliary Cooling Water system D emineraliz ed Water system These systems, each of which is critical to plant operation, will be inspected, adjusted, repaired, or replaced as necessary to insure long term, reliable operation. Auxiliary Boiler. Rework of the furnace bottom will necessitate the relocation of the exisiting Auxiliary Boiler. Based on results of a recent condition assessment, economics favor replacement of the Aux Boiler when compared to dismantling, relocating and reassembling the existing Aux Boiler. Fire Protection System The configuration of the existing fire protection system will be reviewed in light of the other modifications and upgrades made to the plant equipment. The fire protection SCOPE OF PROJECT King Plant Rehabilitation Project Page 7 of 7 system will be replaced, modified, and /or upgraded in accordance with recommendations and requirements of Xcel's property insurance carrier.
