The document discusses the drivers for new transmission systems to transport renewable energy in the United States. It notes that renewable resources tend to be located far from areas of high energy demand and coal consumption. It argues that a national transmission system is needed to connect renewable energy sources to major population centers in a cost-effective way. Such a system would allow renewable resources across large regions like the Great Plains to be harvested and their variability dampened. It asserts that intermediate states must also benefit from such transmission infrastructure for large multi-state projects to be viable.

14. Federal Direction
Ensure that 10 percent of the nation's
electricity comes from renewable
sources by 2012 and 25 percent by 2025
Implement an economy-wide cap-and-trade
program to reduce greenhouse gas
emissions 80 percent by 2050
Reduced GHG in tandem with retiring coal
plants opens a window for alternative
sources for energy mix, if it can be
delivered to the end-user market

Grid built to handle transmission &
distribution needs for a utilitys service
territory with ties to only adjoining
utilities
Never intended to handle cross-country
transmission of energy
Transmission investment and rate of
return have historically lagged generation

According to North American Reliability
Council new generation supplies are
forecast to outpace transmission,
constraining wind development with a
planned 145,000 megawatts of capacity
over the next 10 years
Generation growth over 10 years: 21%
Transmission line growth over 10 years:
10% with 1,700 circuit miles

North / South grid allows leveraging
natural variability of wind throughout
Great Plains and complementary solar,
just as a portfolio of different stocks
lowers overall volatility
East / West grid allows delivery to the
target markets with greatest value to
producers and producing states

27. Summary
Environmental concerns are leading
generation source changes
Renewable resources need connections
to end-user electric markets which offer
higher prices to spur renewable growth
Price convergence will multiply the need for
transmission to accommodate renewable
energy generation
Energy storage will dampen RE variability,
adding greater reliability and value to its
generation

28. Summary, contd.
Choice between less-productive, local
renewable resources vs. highly-productive
resources connected to high-demand,
high-priced markets
Currently, intermediate states can derail
renewable generation and its multi-state
transmission to demand centers
Need to incent the intermediate states to
gain from transmission, not just producer
and end user

29. Summary, contd.
To harvest best resources with economies
of scale, national extra-high voltage
transmission system similar to interstate
highway & natural gas pipeline system
is needed
Combine different RE technologies whose
energy production profiles are
complementary to improve transmission
asset utilization and project rate of return
