Southern Alberta 20-year Long-term Transmission Plan, Alberta, Canada
The AESO’s Long-term Transmission Plan provides market participants, customers, government and interested stakeholders a summary of the proposed development of Alberta’s transmission system over the next 10 to 20 years. The plan is a blueprint for ensuring a robust transmission system that will provide reliable service to Albertans for years to come, and it facilitates a competitive marketplace that recognizes investment in new generation depends on access to an unconstrained and efficient transmission system. The plan summarizes the results of the regional transmission plans.
CF POWER conducted power flow, transient stability, voltage stability and short circuit analysis for the AESO’s Long-term Transmission Plan.
Fidler 240/138 kV Substation System Planning Study and Conceptual Design, Alberta, Canada
The Fidler 240/138 kV Substation was proposed to alleviate existing constraints and provide sufficient capacity to meet near and long term needs.
CF POWER performed detailed near and long term studies to ensure that the Fidler Substation would be in compliance with the Reliability Criteria and Reliability Standards. And conducted transient stability analysis, power flow and voltage stability analysis, and short-circuit studies. CF Power also prepared the conceptual design for the Fidler Substation.
The estimated project cost is $90 million.
Alberta - BC Intertie Transfer Capability, Alberta, Canada
Alberta Intertie Transfer Capability needs to be reviewed when major projects are energized.
CF POWER performed power flow, voltage and dynamic stability analysis to establish additional transfer capability from 2013 to 2016 for the Alberta-BC Intertie Transfer Capability Upgrade.
The Alberta-BC Intertie Transfer Capability Upgrade is currently under implementation.
MacKay River Power Plant, Alberta, Canada
The Mackay River Power Plant is a 203 MW industrial cogeneration project located in the MacKay River oil sands development.
CF POWER’s responsibilities included preparing the regulatory applications for the generator and transmission interconnections and performing power flow, transient stability and short circuit analysis.
CF POWER prepared the engineering study report, facility designs and cost estimates for the industrial customer interconnection application to the AESO and coordinated communications on behalf of the client with the AESO, the transmission facility owner, the distribution facility owners and Alberta Utilities Commission throughout the entire customer connection process. An analysis of the proposed generation projects system impact was carried out.
1000 MW Power Plant Interconnection Study, Alberta, Canada
CF POWER facilitated the connection process of a 1000 MW power plant with the Independent System Operator (ISO), coordinated with the Transmission Facility Owners (TFOs), and prepared the interconnection study scope, engineer studies report, facility design and cost estimates. CF POWER established a transmission system model and generator model, performed power flow, short-circuit, dynamic and sub-synchronous torque interaction studies, analyzed the system impact of connecting the proposed generators to the grid, developed connection alternatives and recommended the preferred alternative for connecting the power plant considering technical, economic and environmental factors.
CF POWER also prepared regulatory applications for the generator and transmission interconnections.
Alberta Load Shedding Service for Import Extension Study, Alberta, Canada
The current Load Shed Service for Import (LSSi) table was extended to reflect this new import level and system peak conditions.
CF POWER extended the current Load Shed Service for Import (LSSi) table to reflect new import levels and system peak conditions.
Alberta BC Intertie Restoration Project, Alberta, Canada
The AESO identified the need to restore the intertie combined transfer capability for Path 1 (British Columbia – Alberta) and Path 83. The AESO is in the process of restoring the intertie’s total transfer capability (TTC).
CF POWER performed a comprehensive study to identify the existing constraints on the intertie and proposed technical alternatives to restore the intertie to its designed capacity.
Vermillion to Red Deer and Edgerton to Provost (VREPTD) 240 kV Transmission Development (VREPTD) Planning Study, Alberta, Canada
The AESO commissioned a planning study to confirm whether the need for the Hanna Phase 2 remains with the proposed VREPTD project in place and whether the VREPTD project depends upon the completion of Hanna Phase 2. Another objective of the study was to compare Alternatives 1 and 3 for the VREPTD from the technical perspectives of power flow and voltage stability and identify the technical preferred alternative.
CF POWER performed power flow and voltage stability studies for the study report.
Montana-Alberta Tie Line (MATL) Remedial Action Scheme (RAS) DSA Tools User Defined Model, Alberta, Canada
The Montana-Alberta intertie consists of several elements in series, including three transmission line segments. Power may be injected from a substation at the center of the line, where the wind farm is connected. It was determined that the entire line would be tripped if any of the series-connected segments tripped.
CF POWER developed a user-defined model for a Montana-Alberta Tie Line MATL RAS using DSA Tools. The model consists of a series of protection modules. Each module implements one specific protection function.
Western Electricity Coordinating Council (WECC) TPL Compliance, Alberta, Canada
CF POWER reviewed the client’s compliance program, identifying gaps with respect to compliance with WECC reliability standards, and carried out studies to ensure the compliance of the transmission system with WECC TPL-002 and TPL-003 transmission planning standards requirements. CF POWER performed power flow and dynamic studies, developed mitigation plans for the issues identified and prepared engineering study reports for submission to the WECC. The studies included maintenance and planned outage analysis (Category B dynamics) and maintenance planned outage analysis (Categories C5, C6-9 power flow analysis).
Alberta Transmission Competitive Bidding Process, Alberta, Canada
CF POWER assisted our client’s participation in the first Alberta transmission competitive bidding process (500 km, 500 kV transmission line into the Fort McMurray area).
Northwest Fort McMurray 240 kV Regional Transmission Development, Alberta, Canada
A 130 km long 240 kV loop transmission line was proposed to handle the forecasted increase in load and generation requirements in the Fort McMurray area. There were several requests for transmission system access in the area, with the first developments requesting an in-service date as early as 2013. There were no existing transmission facilities at the time which were able to handle the expected load and generation growth in the area.
CF POWER performed detailed studies on the proposed plan for the near term and the long term to ensure compliance with the Reliability Criteria and the Reliability Standards. Transient stability analysis, power flow, voltage stability analysis, and short-circuit studies were conducted for system normal condition (Category A), single contingencies (Category B) and selected two element contingencies (Category C).
