After burning coal to light up Cincinnati for six decades, the Walter C.
Beckjord Generating Station will go dark soon—a fate that will be
shared by dozens of aging coal-fired power plants across the U.S. in
coming years. Their owners cite a raft of new air-pollution
regulations from the Environmental Protection Agency, including a
rule released Wednesday that limits mercury and other emissions, for
the shut-downs.
But energy experts say there is an even bigger reason coal plants are
losing out: cheap and abundant natural gas, which is booming thanks
to a surge in production from shale-rock formations in the U.S.
"Inexpensive natural gas is the biggest threat to coal," says Jone-Lin
Wang, head of global power research for IHS CERA, a research
company. "Nothing else even comes close."

4. Many big utilities have announced retirements of coal-burning
power plants, including Southern Co., Progress Energy Inc., First
Energy Corp., Xcel Energy Inc., Ameren Corp. and the Tennessee
Valley Authority.
Coal consumption by the power sector is expected to fall 2% this
year and 4% next year; even small movements are important
because utilities burned 92.4% of the 1,071 million short tons of coal
distributed last year in the U.S.
American Electric Power Co., the biggest user of coal in the U.S.,
expects to burn 67 million tons of coal this year but anticipates its
consumption will drop to 50 million tons after it retires 25 coal-
burning generating units in six states by 2015.
Experts think 10% to 20% of U.S. coal-fired generating capacity will
get shut down by 2016.

6. Xcel socks Denver with nation's 2nd-highest electric-rate
increase
Monday December 12, 2011 By Mark Jaffe The Denver Post
Denver had the second-highest increase in electric rates in the country in
the first half of this year — 21.4 percent, according to the U.S. Bureau of
Labor Statistics. Honolulu, with a 24.8 percent increase from the same
period in 2009, was first.
The average rate hike for metropolitan areas with more than 1.5 million
people was 0.3 percent. The jump in Xcel Energy bills was driven by two
rate increases awarded by the Colorado Public Utilities Commission: $112
million in May 2009 and $128 million last December.
Those increases were mainly to pay for the new $1.3 billion Comanche 3
coal-fired power plant and the $283 million conversion of the Fort St. Vrain
nuclear plant to a gas-fired plant, said David Eves, chief executive of Xcel's
Public Service Co. of Colorado.

7. Gas / Electric Utility Cost
Management

9. Fluorescent Lamps: The most common fluorescent tubes used today are the T8 4’ tube
and T12 – 4’ tube; they consume between 28 and 40 watts each, not including the
ballast. They are replaced with LED 4’ tubes which consume between 13 and 18 watts
with a service life of 40,000 hours. Typical energy savings = 35% to 45%
Garage / Parking Ramp Fixtures: Moving from HPS or MH to Induction Fixtures can
typically provide for energy savings ranging from 50% to 75%, depending on the
existing application that is being replaced.
High Bay Fixtures: When 400 watt MH fixtures are replaced with 150 watt Induction
fixtures; a 67% energy saving is achieved – 56% energy savings when it is replaced
with a 200 watt high bay Induction fixture.
Exterior Building Wall Pack Fixtures: Moving to Induction fixtures; a 50% energy
savings is commonly achieved.
Parking Lot / Drive Way Fixtures: Moving to Induction fixtures; a 50% energy
savings is commonly achieved.
