Challenges
Challenges
Increasing focus on renewable sources of energy has highlighted the weakness in the existing system and in the planning processes used to develop new transmission
Concerns over the environmental impact of burning fossil fuels will continue to challenge the industry
Existing transmission system:
aging and in need of upgrades
was not built to support competitive regional markets and is not adequate to meet future demand growth and integrate potential renewable generation resources
not designed to be adaptive to major changes in the generation supply mix
Opportunities
Strategic expansion of the transmission grid, including development of a robust national EHV transmission system can better prepare the United States to address these challenges in a timely, cost effective and efficient manner.

Examples of evolving transmission technology at AEP
Examples of evolving transmission technology at AEP
Independent âphase shiftingâ which allows a single 765 kV circuit to be operated as 2 circuits to enhance reliability and avoid loss of load
Use of 765 kV voltage level and advanced conductor configurations that significantly reduce âLine lossesâ â losses at 345 kV are 6+%, while 765 kV losses are less than 1% - lower line losses means less generation is needed.
Use of embedded advanced telecommunications technology (Smart technology) that allows real time monitoring and management of the transmission grid and can be used to proactively identify potential faults.
The âThree Horsemenâ
The âThree Horsemenâ
Planning: How do we plan expansion of the grid in a coordinated way, with the kind of vision that led President Eisenhower to propose our interstate highway?
Siting: How do we site needed transmission on an expedited basis to ensure that the necessary infrastructure is developed to support inevitable changes to our supply portfolio?
Cost Allocation: How do we keep the 300 pond elephant â who pays for this???? â from derailing necessary infrastructure development?
âWe need a true nationwide transmission version of our interstate highway system; a grid of extra-high voltage backbone transmission lines reaching out to remote resources and overlaying, reinforcing, and tying together the existing grid in each interconnection to an extent never before seen.â

Converging factors make the timing right for these advances
Rising energy prices - Equipment maintenance needs, new facilities to serve new load, more stringent environmental requirements and increasing fuel costs are causing electricity prices to increase at an unprecedented rate.
Technology affordability and accessibility - Advanced communications and control technologies are less costly, more widely available and easier to use than ever before, and users are increasingly savvy.
Environmental action - People are increasingly aware of greenhouse gas emissions and their role in global climate change, and are increasingly concerned about sustainable action to address them.
Infrastructure improvement needs - Much of the electricity delivery system is 20 or 30 years old or more. Existing equipment needs to be updated to accommodate new technologies and new facilities are needed to support the growth in customer requirements.
Rising expectations - Adoption of sensitive electronics through all levels of society has increased the need and expectation for a reliable supply of electric power.
