Our Plants

AMP - Fremont Energy Center

AMP – Fremont Energy Center

AMP Fremont is a 540 MW nominal load 2 x 1 natural gas fired generating station with 163 MW of duct-firing capacity.

 

NAES sets a new course for safety, budget and staffing at AMP Fremont

after acquiring this combined-cycle plant in the midst of its commissioning, AMP called on naes to deliver maximum value while reducing costs for its member communities

American Municipal Power (AMP) and its members self-operate several electric plants. However, for its first combined-cycle gas turbine facility – the 703 MW Fremont Energy Center in northwestern Ohio – AMP enlisted NAES based on its extensive experience in combined-cycle plant operations and greenfield plant startups. By hiring the third-party operator, AMP hoped to achieve optimal performance without the lengthy learning curve usually associated with a new plant and technology.

Multiple Owner Support
NAES’ experience in working with a client’s asset management team and with multiple-owner projects provided several benefits to AMP and its 100-plus participating members. For one, NAES was able to quickly build and manage the operating budget while establishing administrative processes that streamlined decision-making efforts. NAES’ proven procedures provided an effective methodology to assist the owner in reviewing and approving the annual operating and capital budgets. With an approved budget and effective procurement procedures, NAES was able to make timely purchases of materials, supplies and services to support the owner’s operating objectives.

 

Timely, Economical Staffing Plan

When AMP engaged NAES, Fremont was ready to begin commissioning and startup procedures. To stay on schedule, NAES had to aggressively recruit, train and qualify an operating staff of 23, with the first employees arriving on site in just over four weeks from Notice to Proceed. To shorten the learning/training curve, NAES transferred six seasoned personnel from other NAES facilities, reducing the time needed to implement their time-tested processes and procedures.

For the balance of the staff, NAES hired talented employees from the local area who had worked in both union and non-union environments. Because the wages and benefits offered were competitive with prevailing packages in the area, and personnel were satisfied with the professional management of the plant, the facility has remained non-represented.

 

Owner-Operator Teamwork

At the time AMP acquired the Fremont Energy Center, it maintained a robust regulatory support department of environmental and NERC professionals at its Columbus, Ohio, offices. Following Notice to Proceed, AMP and NAES identified and assigned detailed roles and responsibilities for environmental and NERC tasks. NAES employees at the site were able to perform monitoring and data preparation tasks that complemented AMP’s reporting responsibilities. When the company experienced support-staff changes, they were able to transition additional environmental responsibilities to NAES site and corporate personnel. This agility on the part of NAES staff, who also took on additional procurement responsibilities, has resulted in an overall cost savings for AMP.

 

Best Practices Improve Plant Safety and Reliability

With AMP’s blessing, NAES has pursued a number of best practice improvements at the Fremont Energy Center. Two of these were recognized by Combined Cycle Journal (CCJ) in its 2015 Best Practice Awards: a combustion turbine (CT) package fire-protection system upgrade and an improved identification system for electrical switchgear.

The fire-protection upgrade was prompted by NAES personnel discovering that the gas detectors in the combustion-turbine packages were operating erratically. This led to sporadic trips and potentially unsafe conditions. After researching several solutions, NAES opted to route all eight gas-detection sensors in each CT to a new programmable logic controller (PLC) panel after converting the digital signals to analog. The only modification required was to pull new signal wires to the sensors. This change has resulted in zero erroneous trips and enhanced monitoring of potential gas in the CT packages.

Following commissioning, the site received an accurate but cumbersome set of electrical drawings that often presented challenges when it came to matching components with the specific electrical sources feeding them. This had the potential to cause errors in Lock-Out/ Tag-Out (LOTO) procedures.

NAES personnel embarked on a project to create a set of drawings that clearly illustrated the power source for each piece of equipment. These drawings presented a visual representation of the physical layout of each motor control center (MCC) and panel board. In addition, they color-coded each electrical switchgear line-up and attached copies of the associated drawings to cabinet fronts. Site employees can now perform LOTO duties more accurately with a reduced chance of error.

    CAISO Generator Modeling Process and Data Requirements

    Don’t wait until the last minute. You should allow time for at least one iteration with CAISO so that you are complete and deemed compliant before your deadline.

    On August 1, 2018, CAISO introduced a revised Business Practice Manual for Transmission Planning Process (BPM), which includes new data requirements for interconnected generation resources within the ISO’s footprint. Section 10 of the BPM establishes revised data requirements and compliance procedures for all participating generators including non-NERC registered entities. While additional requirements have been placed on larger NERC registered facilities, these changes may pose an even greater burden to entities that have been exempt from NERC mandated modeling and protection requirements.

    New data requirements include voltage and frequency protection models, power flow models, and in some cases, sub-synchronous resonance models. These models must be verified using criteria listed in the BPM, which can only be performed by entities with modeling software and knowledge of modeling practices.

    NAES is prepared to assist entities with data aggregation, modeling, and testing to ensure compliance with CAISO’s data requests. The following links will allow entities to determine when to expect their individual data requests (phase) and what data will be required (category).

    Business Practice Manual (BPM)

    Entity Category and Phase Listing

    CAISO Transmission Planning Website

    TPL-007

    TPL-007 establishes planning criteria for induced currents caused by geomagnetic disturbances. The standard is applicable to facilities using transformer(s) with a high side, wye grounded winding operated above 200 kV and can require both submittal of general geomagnetic data (R2) and thermal impact assessments (R6) depending on results of Planning Coordinator analysis.

    VOLTAGE AND REACTIVE (VAR) STANDARDS

    VAR-501-WECC

    VAR-501-WECC requires applicable entities within the WECC region to confirm performance settings and characteristics of Power System Stabilizers (PSS). NAES provides physical testing and reporting services to address WECC’s specific PSS requirements.

    PERSONNEL PERFORMANCE, TRAINING AND QUALIFICATIONS

    PER-006

    PER-006 requires Generator Operators to provide training to personnel who are responsible for the Real-time control of a generator. NAES has developed specific protection system training materials suitable for compliance with the Standard and provides this training both on and off site

    PROTECTION AND CONTROL (PRC) STANDARDS

    PRC-001

    PRC-001 requires entities to coordinate protection system changes with other affected parties. NAES offers both procedural documentation and engineering services to establish the required coordination for both PRC-001 and PRC-027.

    PRC-002

    PRC-002 requires the installation and operation of disturbance monitoring equipment (DME) for applicable entities. NAES can assist with the design and installation of DME as well as ongoing compliance support.

    PRC-019

    PRC-019 requires applicable entities to show coordination between voltage regulating controls, limiters, equipment capabilities, and protection settings. NAES produces PRC-019 specific coordination studies for both traditional generators and renewable projects to establish compliance with the Standard.

    PRC-023

    PRC-023 requires load responsive protective relays be set according to criteria within the Standard to ensure settings do not limit transmission loadability. NAES provides full engineering analyses to maintain compliance with this Standard.

    PRC-024

    PRC-024 requires applicable entities to ensure generator protective relays do not trip within predefined frequency and voltage limits. NAES can complete protection settings analyses and provide compliance documentation that clearly identifies protection settings as they relate to NERC’s “no trip” zones.

    PRC-025

    PRC-025 establishes minimum settings requirements for load-responsive relays protecting generators, step up transformers, and auxiliary transformers. NAES utilizes predefined calculation options as well as simulations to determine a facility’s compliance status and development of new relay settings if required.

    PRC-026

    PRC-026 requires applicable entities to perform load responsive relay settings analyses based on criteria identified within the Standard. Entities are typically notified by the Planning Coordinator when an analysis is required. NAES performs all required studies to establish compliance.
