Growing the Transmission Grid
The High Voltage “Grid” West – East Split
Economies of Scale 345,000 Volts 120 Volts
Transmission Distribution
Powering the Upper Midwest… Missouri River Dams Lignite Power Plants
Typical Daily Electricity Demand By Hour
Generation = Demand No Storage Capability The “GRID”
The Grid Pro’s Con’s Reliable Redundant Accessible Access To Markets Nationwide Con’s Everyone Is Connected – Problems Can Cascade Remote Congestion Can Limit Local Schedules
Regulation: FERC: Regulates Interstate Electricity Transmission State Public Service Commissions: Regulate Internal State Transmission NERC: Sets Mandatory Reliability Standards
Energy Markets
Expanding The Grid $125,000 per mile for 60,000 Volt lines Transmission is ~7% of Average Electric Bill
MISO Regional Generation Outlet Study One particular 20 percent wind plan $15 to 30 billion dollars (in addition to cost of wind turbines - $3 million plus per tower) 10 plus years of development Significant transmission improvements and costs are needed to meet potential carbon reduction mandates through the use of wind generation 18,000 MW or $30 billion in new generator Utilization or capacity for wind is typically 30% to 40% for new projects Reliability planning requires enough generation available to meet customer peak demand On-average the last few years, wind produces 10% or less of its name-plate on-peak $15 to $30 Billion of needed transmission upgrades 16
