Burning Coal, Burning Cash
Detroit Edison’s Dependence
on Imported Coal
T
he cost of importing coal is a drain on Michigan’s economy, which currently relies heavily on coal-fired power.
Paying for coal from out of state each year comes directly
out of the pockets of ratepayers. This November, voters can help
keep more of that money in state by passing a 25 percent by 2025
renewable energy standard, proposed via ballot initiative.
Detroit Edison, a subsidiary of DTE Energy and the state’s
largest provider of electricity services, relied on coal for 77 percent
of its power supply in 2010. All the coal its power plants burned
that year was imported, mainly from mines in Wyoming, Kentucky, and West Virginia. To pay for those imports, the utility sent
more than $615 million out of Michigan—nearly half the state’s
total expenditures on coal imports, and more than any other
Michigan power producer. The utility’s Monroe power plant, near
the city of Monroe, is the most import-dependent power facility
in Michigan, having spent $423 million in 2010 to purchase outof-state coal.
Despite having no in-state coal supplies, Michigan as a whole
relied on coal for 58 percent of its in-state electricity generation
in 2010. To supply that power, all Michigan power producers
collectively paid nearly $1.3 billion to import coal. From 2002
to 2010, their cumulative purchases of imported coal reached
nearly $10.4 billion. More than half of this total—$5.4 billion—
was spent by Detroit Edison, while during those years the price
the utility paid for coal increased by 81 percent.
Detroit, Michigan. The cost of importing coal is a drain on Michigan’s economy,
which relies heavily on coal-fired power. For example, Detroit Edison, the
state’s largest power provider, sent $615 million out of Michigan in 2010 to pay
for the coal its power plants burned. Investments in homegrown renewable
energy can help stimulate the economy by redirecting funds into local
economic development—funds that would otherwise leave the state.

• Spent $615 million on coal imports in 2010
• Cumulatively spent $5.4 billion on coal
imports from 2002 to 2010
Note: Not all these funds will necessarily land in
the state where the mining occurs. Mine owners
may divert the profits to parent companies in
other locations, for example. Amounts also
include the cost of transportation.

Clean Energy Solutions Can Boost Michigan’s Energy Independence
Investing in homegrown renewable energy is a smart and responsible solution to reducing Michigan’s
dependence on imported coal and keeping more money in the local economy. Michigan has a wealth
of renewable energy resources like wind, solar, and bioenergy; yet these resources supplied just
2.5 percent of the state’s power in 2010 and 3.8 percent in 2011. Utilities are already required by
state law to produce at least 10 percent of the state’s power needs from renewable energy by 2015;
but the state can reap significant benefits from doing more. This November, Michigan voters will
be offered a ballot proposal to boost the state’s renewable energy requirement to 25 percent
by 2025. Doing so would spark $10 billion in new investment and create thousands of Michiganbased jobs. More than 30 states have adopted such renewable energy policies, with a dozen states—
including Illinois and Minnesota—having similar or higher targets.
Increasing renewables in Michigan to 25 percent by 2025 is an achievable goal that will curb coal
use and help keep energy dollars local. For Detroit Edison, a 25 percent renewable energy standard
could help keep as much as $866 million from leaving the state to import coal cumulatively from
2016 through 2025.
Investing in energy efficiency is another quick and affordable way to replace coal-fired power while
boosting the local economy. Michigan took an important first step to tap into its tremendous energy
efficiency potential in 2008 by requiring utilities to reduce electricity use, ramping up to an annual
savings of 1 percent by 2012. The policy has been a success—in 2010, electric utilities exceeded their
annual target by nearly 50 percent and avoided $554 million in energy costs, a savings of $4.88 for
every dollar invested in energy efficiency. Twenty-two other states have adopted such power-saving
targets, with several committing to annual savings of 2 percent or more.
Michigan has excellent
potential for developing
in-state wind power and
other renewable energy
resources, which can help
reduce the state’s dependence on imported coal
while creating jobs and
other economic benefits.
