SCPPA seeks proposals related to the specified Areas of Interest set forth in Section III below, to enable informed

qualified Respondents to this Request for Proposals (RFP).

In order to submit a Proposal in response to this RFP, Respondents must meet the following minimum

qualifications:

• Employs personnel who have had experience working on REpower/Senvion MM92 WEC

• Experience servicing and maintaining wind facilities at least 50MW in size

Responses to this RFP are due on or before January 20, 2026, as described below in Sections IV and VI.

II. BACKGROUND

SCPPA is a joint powers authority, and a public entity organized under the California Joint Exercise of Powers Act

found in Chapter 5 of Division 7 of Title 1 of the Government Code of the State of California, and through the

SCPPA Joint Powers Agreement, for the purposes of planning, financing, developing, acquiring, constructing,

operating and maintaining projects for the generation or transmission of electric energy. SCPPA also facilitates

joint service contracts, at the request of its Members, to aggregate like project efforts among its Members for the

purposes of developing energy efficiency, demand response and resource procurement programs or projects to

improve operating efficiencies and reduce costs.

Membership of SCPPA consists of eleven cities and one irrigation district, which supply electric energy within

Southern California, including the municipal utilities of the cities of Anaheim, Azusa, Banning, Burbank, Cerritos,

Colton, Glendale, Los Angeles, Pasadena, Riverside, and Vernon, and the Imperial Irrigation District. SCPPA is

governed by its Board of Directors (Board), which consists of representatives from each of its Members. The

management of SCPPA is under the direction of an Executive Director who is appointed by the Board.

The Linden Wind Project is a 50-Megawatt (MW) wind facility consisting of 25 2-MW REpower MM92 WEC, spread

over approximately 1,880 acres. This site is located in Klickitat County, Washington, 5 miles from Goldendale.

The WECs consist of a tower, a turbine nacelle, blades, controller, control panels, converters, any VAR control

technology, wind vanes, FAA lighting, grounding, and anemometers.

III. AREAS OF INTEREST

SCPPA has an interest in O&M Services and the following areas of interest to meet its needs:

1. Scheduled Maintenance, including periodic operational checks and tests, services that require the use of a

crane, and regular preventive maintenance required on all WECs in accordance with industry norms,

prudent utility practices, and the original equipment manufacturer’s (OEM) documents.

2. Proactive Maintenance, including proactive maintenance strategies aimed at extending the operational life

and efficiency of the Linden Wind Energy Converters (WECs). This includes component-level maintenance

to replace aging or underperforming systems with newer, more reliable technologies. Respondents should

consider:

o Eligibility for Production Tax Credit (PTC): Proposals should reflect strategies that enable

qualification for PTC, including a timeline for inspection, evaluation, and commencement of

improvements by July 4, 2026.

o Site Assessment and Component Replacement: Scope may include turbine component upgrades

(e.g., blades, nacelle internals, converters) that improve generation output and reliability while

maintaining compatibility with existing foundations and feeder layouts to avoid costly disruptions.

o Regulatory Compliance and Exemption Strategy: Proposals must address compliance with

upcoming NERC PRC-029 standards, particularly Requirement R6 enforcement beginning May

2026, which mandates documentation for hardware exemptions. In such cases, Respondents

should outline a strategy for maintaining Linden’s exemption status, including detailed justification

and documentation to support exemption requests for both existing and upgraded equipment.

3. Other services that are not included as a part of the Scheduled Maintenance that may be required for the

purpose of achieving and maintaining each WEC in accordance with industry norms, prudent utility

practices, and the OEM documents, including additional repair services, improvements to increase the

availability of life of the WECs, software updates, and the installation or change of parts if requested by the

owner/owner’s designated representative.

4. Staffing schedules include, but are not limited to, technicians and supervisory personnel, on-site during

normal business hours; 5 days and 40 hours per week. When necessary, personnel should be available to

support the facility outside of normal business hours.

5. The Human Machine Interface (HMI) on the site is provided by the OEM. The Respondent must be able to

use the existing control system and SCADA interface or provide a new control system and SCADA interface

as part of their proposal allowing for continuous, around-the-clock monitoring, remote and onsite fault

clearing, control of the WEC, and operational and performance data processing, without interruption.

6. Establish and maintain work clearance procedures for the lockout-tagout of the WECs and safeguard

personnel, this includes but is not limited to outage clearance coordination, and callout of local emergency

first responders when necessary.

7. Provide to owner/owner’s designated representative all data available and used by successful Respondent

for the performance of these services.

8. Handling and management of all on-site hazardous materials and all wastes generated by or used in the

performance of any services provided, including permitting and regulatory reporting.

9. Oversight and coordination of planned and unplanned outages involving the WECs as directed by the owner

or owner’s representatives.

10. Employee training necessary to perform the services described in compliance with industry norms, prudent

utility practices, and the original equipment manufacturer’s (OEM) documents. SCPPA and its designated

representative may request safety training for site-specific climbing equipment, emergency descent devices,

and rescues.

11. Procurement and maintenance services for a running stock of spare parts and consumables to be stored

on-site in owner’s warehouse necessary to conduct periodic maintenance or common repairs. Spare parts

and consumables kept onsite shall be considered the SCPPA’s property once received and an updated

budget, cost and stock list must be provided to owner and owner’s designated representative periodically.

Proposals will be evaluated considering qualitative and quantitative factors including price, project schedule,

experience, control system integration, financial standing, organizational structure, and degree of objection to terms

and conditions.
