Most of the electrical transmission components have been in existence for many years. It is generally agreed that some replacement and upgrading of current lines will have to be done, and that new lines need to be constructed to maintain the system’s overall reliability.
Four significant challenges to improving the power grid infrastructure are:
- Siting new transmission lines (and obtaining approval of the new route and needed land) when there is local opposition to construction
- Determining an equitable approach for recovering the construction costs of a transmission line being built within one State when the new line provides economic and system operation benefits to out-of-State customers
- Ensuring that the network of long-distance transmission lines reaches renewable sites where high-quality renewable resources are located, which are often distant from areas where demand for electricity is concentrated.
- Addressing the uncertainty in Federal regulatory procedures regarding who is responsible for paying for new transmission lines; this uncertainty affects the private sector’s ability to raise money to build them.
