Collaborative Regional Transmission Plan IDs 11 Major Projects
RALEIGH, N.C., Feb. 1, 2013 /PRNewswire/ -- Participants in the North Carolina Transmission Planning Collaborative (NCTPC) have identified 11 major transmission projects, representing more than $318 million in investments over the next decade, as part of the 2012-2022 Collaborative Transmission Plan for North Carolina (2012 plan).
The 2011 plan included an estimate of $296 million for 11 projects. One of those projects was completed by Progress in December 2012. One new project was identified by Progress which ended up replacing one of the 2011 projects. In-service dates and cost estimates for some projects in the 2012 plan that are planned or underway have been revised based on updated information.
The collaborative was formed in 2005 to develop a shared plan for electric transmission system enhancements in the state. Participants include Duke Energy Carolinas, Progress Energy Carolinas, North Carolina Electric Membership Corporation and ElectriCities of North Carolina. Since its inception in 2005, projects totaling $839 million have been identified in the NCTPC plans, with $306 million placed into service through 2012, $197 million currently under construction, $91 million still in the planning stage, and another $245 million being deferred outside the planning horizon or cancelled as a result of changing system requirements.
The scope of the 2012 planning study included a base reliability analysis for transmission needs to meet load growth between 2013 and 2022 as well as an analysis of various system conditions under a number of hypothetical resource supply option scenarios.The Resource Supply Options for the 2012 NCTPC Study consisted of two types of scenarios to examine the transmission system impacts of hypothetical generation resources:
- Option 1 examined injecting 500 MW of power into the transmission system from a hypothetical generation resource in Davidson County, N.C., located near the Duke Energy Buck Plant.
- Option 2 examined the impact of three different Wind Generation Scenarios as part of the joint NCTPC – PJM inter-regional study. The different scenarios were evaluated with varying levels of wind energy penetration originating off the North Carolina / Virginia coast and varying levels of power transfers between the PJM, DEC and PEC systems.
