Nebraska Transmission System is part of the Eastern Interconnection

Transmission System is a Network Compliance with North American Electric

Reliability (NERC) standards for planning & operating the system

The Southwest Power Pool (SPP) will conduct transmission studies for Interconnection of generation to NPPD, OPPD and LES system

Limited transmission capacity in existing system◦ Western Nebraska extremely limited

Can interconnect additional wind generation to serve Nebraska customers without extensive transmission expansion

But extensive transmission expansion required for large scale wind development ◦ Thousands of MWs requires hundreds of millions $ in transmission

investment

Wind developers that want to interconnect in Nebraska to the NPPD, OPPD or LES transmission system can do so by: ◦ Submitting an Interconnection Request to SPP◦ Paying for the transmission studies ◦ Signing an Interconnection Agreement◦ Paying for the transmission upgrades
