Calpine and ExxonMobil Sign CO2 Transportation and Storage Agreement for CCS Project in Texas

LCG, April 24, 2025--Exxon Mobil Corporation (ExxonMobil) announced yesterday an agreement with Calpine Corporation (Calpine) to transport and permanently store up to 2 million metric tons per annum (MTA) of CO2 from Calpine’s Baytown Energy Center, a natural gas-fired facility located near Houston, Texas. This is part of Calpine’s Baytown Carbon Capture and Storage (CCS) Project that is designed to add CCS for the facility’s CO2 emissions. The Calpine facility could then provide a 24/7 supply of low-carbon electricity to the Texas grid plus steam to nearby industrial facilities.

Minnesota Power Completes Fourth Phase of Bison Wind Energy Center

LCG, January 20, 2015--Minnesota Power, a division of ALLETE, Inc., announced yesterday that it has completed commissioning on the fourth phase of its Bison Wind Energy Center, located in south-central North Dakota. The estimated investment cost for the 205-MW expansion project is $345 million. The total generating capacity of the Bison Wind Energy Center is now nearly 500 MW.

The project, Bison 4, includes 64 wind turbines that deliver power via a 465-mile direct current (DC) transmission line that connects the Square Butte Substation in Center, North Dakota, to the company's Arrowhead substation near Duluth, Minnesota. The first three phases of the Bison Wind Energy Center include 101 wind turbines that were built in 2010-12 and have a combined electric generating capacity of 292 MW.

The North Dakota Public Service approved the Bison 4 site construction permit in September 2013, and construction began that fall. The Minnesota Public Utilities Commission then approved Minnesota Power's petition seeking cost recovery from customers for Bison 4 investments in January 2014.

ALLETE's Chairman stated, "We've made significant strides over the last eight years to bring our energy generation into better balance. Development of renewable energy from wind and water is rapidly transforming our nation's energy landscape and with the addition of nearly 500 MWs of wind from the Bison development on our system, we are providing cleaner energy while maintaining the affordability and reliability of electric power our customers in northeastern Minnesota expect."

Bison 4 is part of Minnesota Power's strategic EnergyForward plan to diversify its energy supply while adding renewables and reducing emissions, including carbon, at power plants.
