Cleco Power LLC, which provides power to more than 240,000 families in Louisiana, uneconomically generated electricity from its Dolet Hills and Brame Energy Center coal plants, at a $123.3 million loss in 2018. If utilities in MISO ran their power plants more efficiently, the average family in Louisiana could have saved $15 a month in electricity bills, or a total of $184 that year.DTE Electric Company, which also provides power to nearly 2 million families in Michigan, uneconomically generated power from its five coal plants—Belle River, Monroe, River Rouge, St. Clair and Trenton Channel—at a $94.7 million loss in 2018. If utilities in MISO ran their power plants more efficiently, the average family in Michigan could have saved $5 a month in electricity bills, or a total of $61 that year.

Utilities Exploit Market Loopholes, Costing Midwest Consumers $350 Million in 2018 - Study Finds Nearly One Fifth of Coal Generation the Midwest Operated Uneconomically
Tuesday, December 1, 2020
Why did renewables become so cheap so fast? And what can we do to use this global opportunity for green growth?
To make comparisons on a consistent basis, energy prices are expressed in ‘levelized costs of energy’ (LCOE). You can think of LCOE from the perspective of someone who is considering building a power plant. If you are in that situation then the LCOE is the answer to the following question: What would be the minimum price that my customers would need to pay so that the power plant would break even over its lifetime?

We Energies to retire 1.8 gigawatts of fossil fuel; utility adding solar, wind, battery storage
WEC Energy Group plans to retire 1,800 megawatts of fossil fuel generation — including the South Oak Creek coal plant near Racine — over the next five years while adding 1,500 megawatts of clean energy and storage capacity along with 300 megawatts of natural gas generation.
|
Klappa said the spending plan, which is $1.1 billion larger than the previous five-year plan, will increase company profits by 5% to 7% a year while also saving ratepayers what amounts to $50 million a year over the next two decades.
...
In broad terms, the plan calls for building 800 megawatts of solar generation and 100 megawatts of wind generation coupled with 600 megawatts of battery storage, which can be used to balance those intermittent renewable resources.
“The data show that battery storage has now become a cost-effective option for us,” Klappa said.
The announcement comes as Wisconsin’s first utility-scale solar plant came online. Jointly owned by WEC subsidiary Wisconsin Public Service Corp. and Madison Gas and Electric, the 150-megawatt Two Creeks Solar Farm in Manitowoc County began commercial operation Monday.
The company said those acquisitions will allow it to retire the 1,100-megawatt South Oak Creek power plant, whose four generators are all more than 50 years old, in 2023 and 2024.
WEC’s oldest coal-fired plant, South Oak Creek is the single largest source of toxic metals dumped into Lake Michigan, according to a Chicago Tribune analysis of federal data.
Last year, the Department of Natural Resources gave WEC until the end of next year to stop using water to remove ash from the boilers, a process that can lead to mercury and other toxins seeping into groundwater.
...
Klappa said closing an older plant like South Oak Creek could save $50 million a year in operational and maintenance costs.
...
Consumer advocates cautioned that ratepayer savings will depend on how regulators handle the hundreds of millions of dollars WEC has invested in fossil fuel plants over the past two decades.
...
On Thursday the Public Service Commission approved a plan for WEC to refinance $100 million of its remaining investment in pollution controls at its Pleasant Prairie coal plant, which WEC retired in 2018 saying it would save millions of dollars for ratepayers. The financing arrangement, known as securitization, is expected to save ratepayers about $40 million. Consumer and environmental advocates, as well as regulators, say securitization could be a key tool for paying off plants that are no longer economic to run.
Despite attempts by the Trump administration to prop up the coal industry, South Oak Creek is the 329th U.S. coal plant targeted for retirement since 2010, according to the Sierra Club. Over the past decade, U.S. utilities have retired or replaced 95,000 megawatts of coal-fired capacity in response to tighter air pollution standards and increasingly unfavorable economics, according to the Energy Information Administration. Another 25,000 megawatts of coal capacity are expected to retire by 2025. In the first six months of 2020, the U.S. electric power sector consumed 30% less coal than in the first half of 2019, according to recent data from the EIA.
...
Alliant Energy, which plans to add 1,000 megawatts of solar generation in Wisconsin, this year has announced plans to close its 415-megawatt Edgewater plant in Sheboygan by the end of 2022, while the company’s Iowa utility said last month it would also close a 275-megawatt coal plant in Lansing on the Mississippi River.

Economic And Clean Energy Benefits Of Establishing A Southeast U.S. Competitive Wholesale Electricity Market
Employment benefits begin accruing immediately after the RTO comes into operation, as lost jobs in coal and natural gas generation are replaced by construction jobs related to wind, solar, and battery deployment. By 2040, the RTO scenario creates 285,000 more jobs relative to the business-as-usual scenario, owing to the construction of 62 gigawatts (GW) of solar, 41 GW of onshore wind, and 46 GW of battery storage.
"To Rid The Grid Of Coal, The Southeast U.S. Needs A Competitive Wholesale Electricity Market" by Sarah Spengeman in Forbes on August 23, 2020 https://tinyurl.com/y67co45m notes that:
The Southeastern United States, one of the country’s only regions without a competitive wholesale electricity market, is dominated by monopoly utilities, which have favored expensive and polluting fossil fuel generation over cheap clean energy. Nearly all Southeast coal plants cost more to run than replacing them with new wind and solar, so continuing to run these uneconomic resources forces customers to foot the bill and inhale dirty air. ...
Competitive wholesale electricity markets, or Regional Transmission Operators (RTOs) and Independent System Operators (ISOs), are public-benefit corporations serving 70% of U.S. electricity customers that arose from electricity restructuring during the late 1990s-early 2000s to cut costs and encourage innovation.
Competition in these markets has reduced wholesale energy costs while creating an entry point for low-cost renewable energy to provide power to the grid. They have also been critical to integrating variable renewable energy – wind and solar – and capitalizing on resource diversity over larger geographical areas. ...
Despite ambitious long-term climate announcements, Southeast utilities are still heavily reliant on expensive-to-run coal plants and are doubling down on risky new gas infrastructure investments, instead of clean technologies of the future. ...
Comparing a competitive regional Southeast market through 2040 to a business-as-usual scenario based on existing monopoly utility Integrated Resource Plans reveals remarkable findings. Introducing a Southeast regional competitive market that optimizes regional transmission and shares resources (key features of other RTOs) would save $384 billion dollars with approximately $17.4 billion average yearly savings through 2040 - 23% lower electricity costs compared to today.
These enormous savings come from cheaper wind, solar, and storage displacing more expensive-to-run coal, along with an RTO-led regional transmission planning scheme where all seven states share power resources and expand transmission to most efficiently meet regional electricity demand. VCE’s WIS:dom model also incorporates electricity distribution infrastructure savings from deploying distributed storage and solar resources.
The Bar graph above shows cost reductions reach nearly 32% by 2040 in the competitive scenario compared to just 10% compared to business-as-usual.
In contrast, the current utility-led planning regime is an inefficient patchwork system. Monopoly utilities plan their electric grids independently from their neighbors and impose fees called “wheeling charges” to ship power across successive utility transmission systems. This incentivizes monopolies to over-build power plants, thereby increasing profits for their shareholders. Together, this significant duplication and overbuild of infrastructure costs customers billions....
