Constellation to Supply ComEd with Hourly Matched Carbon-Free Power -- OPIS

Constellation has signed an agreement with the Illinois utility
ComEd to supply 100% hourly-matched carbon-free electricity to its
offices and facilities, the power supplier announced Thursday.
The deal will deliver an estimated 65,000 megawatt-hours of
nuclear power annually to ComEd's 54 offices and metered sites,
Constellation said.
Most businesses that voluntarily reduce their Scope 2 emissions
do so by matching the power they use on an annual basis with
renewable energy certificates, which represent one megawatt-hour of
renewable power delivered to the grid. But accounting for and
offsetting power on an annual basis can still result in net carbon
emissions.
Most renewable power generation delivers electricity on an
intermittent basis. When the sun does not shine and the wind does
not blow, U.S. grids tend to rely on firm, carbon-emitting
generation sources like natural gas or coal to make up the
difference. As a result, purchasing and retiring abundant day-time
solar power, for example, does not necessarily offset power
consumed after the sun sets.
Businesses have begun to match their power use on an hourly
basis with renewable energy generated at the same time and, in some
cases, at the same location in order achieve true net zero Scope 2
emissions.
"ComEd is committed to doing everything possible to help
Illinois achieve its goal of 100 percent clean energy by 2050, and
that includes reducing the use of fossil fuels and lowering carbon
emissions at our own facilities in every hour of every day," said
ComEd CEO Gil Quiniones in a statement. "Constellation's 100
percent hourly matching carbon-free energy solution provides an
important tool to address the challenges of climate change."
Google, in partnership with AES, first developed an
hourly-matching program in 2020 after determining its annual
matching led to significant carbon emissions, especially from its
data centers which require power around the clock.
Constellation developed a similar scheme with Microsoft in
2022.
Around-the-clock carbon free power remains challenging in many
regions. Many regional transmission organizations do not allow for
hourly tracking in their REC generation systems. M-RETS began
issuing hourly-stamped RECs in 2019. The PJM Interconnection
followed this year, and NEPOOL is working towards it, sources
previously told OPIS.
The Biden Administration issued an Executive Order in 2021
requiring the federal government achieve 50% carbon-free power on
an hourly basis by 2030.
