Kemper County power plant costs and delays highlight lignite coal gasification, syngas production, carbon capture targets, and looming rate plans as Mississippi Power navigates Public Service Commission oversight and shareholder-ratepayer risk.

 

Key Points

Costs exceed $7.5B with repeated delays; rate impacts loom as syngas, lignite, and carbon capture systems mature.

✅ Estimate tops $7.5B; customers could fund about $4.3B

✅ Carbon capture target: 65% CO2 via syngas from lignite

✅ Rate plans pending before the Public Service Commission

 

A Mississippi utility on Monday delayed making proposals for how its customers should pay for an ever-more-expensive power plant, even as the estimated cost of the facility crossed $7.5 billion.

The Kemper County power plant will be tasked with mining lignite coal a few hundred yards away from the plant. That coal is moved through a process that will convert it to syngas. The syngas is then used to drive the energy output of the plant, and the resulting electricity is then moved into the grid, where transmission projects influence regional reliability and capacity.

Thomas Fanning, CEO of parent Southern Co., told shareholders in May that Mississippi Power would file rate plans for its Kemper County power plant this month. But still unable to operate the plant steadily enough to declare it finished, Mississippi Power punted, instead asking to hold rates level for 11 months to pay off costs that have already been approved by regulators.

Mississippi Power says it now hopes to reach commercial operation in June. The plant is more than three years behind schedule, with 10 delays announced in the past 18 months. It was originally supposed to cost $2.9 billion.

The company also said monday that it will have to replace troublesome parts of the facility much sooner than expected, including units that cool the synthetic gas produced from soft lignite coal by two gasifier units, plus ash handling systems in the gasifiers.

Kemper is designed to take synthetic gas, pipe it through a chemical plant to remove carbon dioxide and other chemicals, and then burn the gas in turbines to generate electricity. It’s designed to capture 65 percent of carbon dioxide from the coal, releasing only as much of the climate-warming gas as a typical natural gas plant. It’s a key effort nationally to maintain coal as a viable fuel source, even as coal unit retirements proceed in other states.

Mississippi Power raised its estimate of Kemper’s cost by $209.4 million, with shareholders absorbing $185.9 million, while ratepayers could be asked to pay $23.5 million. Overall, customers could be asked to pay $4.3 billion. Southern shareholders have agreed to absorb $3.1 billion, which has risen by $500 million since November.

The elected three-member Public Service Commission in 2015 allowed the company to raise rates on its 188,000 customers by $126 million a year. That paid for $840 million in Kemper work, which began generating electricity in 2014 using piped-in natural gas. Some items covered by that 15 percent rate increase will be paid off in coming months, but Mississippi Power now proposes to repay costs from regulatory proceedings earlier than originally projected.

In testimony filed with the Public Service Commission, Mississippi Power Chief Financial Officer Moses Fagin said that keeping rates level would reduce whiplash to customers when rates rise later to pay for Kemper, would pay off accumulated costs more quickly and would help the company wean itself off financial support from Southern Co. while maintaining credit ratings and positioning for a possible bond rating upgrade over time.

“Cash flow is important to the company in maintaining its current ratings and beginning to rebuild its credit strength on a more independent basis apart from the extraordinary parental support that has been required in recent years to maintain financial integrity,” Fagin testified.

Spokesman Jeff Shepard said Mississippi Power is still drawing up two rate plans — one requiring a sharp, immediate rate increase, and a “rate mitigation plan” that might cushion increases amid declining returns in coal markets. He said the company isn’t sure when it will file them. Fagin suggested the Public Service Commission set a new deadline of March 2, 2018.

Wynne defends 25% hydro rate cut:

Ontario Hydro Rate Cuts address soaring electricity prices, lowering hydro bills via refinancing, FAO-reviewed costs, and long-term infrastructure investment, balancing ratepayer relief with a projected $21 billion net expense over 30 years.

 

Key Points

Ontario electricity bill relief spreading infrastructure and green energy costs over 30 years via refinancing.

✅ 25% average bill cut; $156 to $123 per month

✅ FAO projects $21B net cost over 30 years

✅ Costs shifted to long-term debt, infrastructure, green energy

 

Premier Kathleen Wynne is making no apologies for the Liberals’ 25 per cent hydro rate cuts, legislation to lower electricity rates that a legislative watchdog warns will cost at least $21 billion over three decades.

In the wake of Financial Accountability Officer Stephen LeClair’s report on the “Fair Hydro Plan,” Wynne emphasized that Ontario electricity consumers demanded and deserved relief.

“You all read the newspaper, you listen to the radio and you watch television — you know the problems that families are having around the province paying for their electricity costs,” the premier told reporters Thursday in Timmins.

That’s why the government moved forward with a rate cut, with recent Hydro One reconnections underscoring the stakes, that will see the average household’s monthly hydro bill drop from $156 to $123 once it fully takes effect next month.

In a 15-page report released Wednesday, the financial accountability officer estimated the initiative would cost the province $45 billion over the next 29 years amid a cabinet warning on prices that electricity costs could soar, while saving ratepayers $24 billion for a next expense of $21 billion.

Both the Progressive Conservatives and the New Democrats oppose the Liberal rate cut, arguing that a deal with Quebec would not lower hydro bills.

But Wynne said the government has in effect renegotiated a mortgage so it will bankroll hydro infrastructure improvements over a longer time period, though some have urged the next government to scrap the Fair Hydro Plan and review options, in order to give customers a break now.

“We’re talking about a 30-year window here. It took at least 30 years, probably 40 years, to let the electricity system degrade to the stage that it had in 2003,” she said, noting “we were having blackouts and brownouts around the province” before her party took office that year.

“There were thousands of kilometres of line that needed to be rebuilt . . . that work hadn’t been done over those generations, so electricity costs were low over that period of time but the work wasn’t being done.”

When her predecessor Dalton McGuinty came to power in 2003, Wynne said Queen’s Park began spending billions on infrastructure improvements, including expensive subsidies for green energy, such as wind turbines and solar panels.

“There’s a lot of work that has been done since then. Literally thousands of kilometres of line have been rebuilt. The coal-fired plants have been shut down. The air is cleaner. There’s less pollution in the air. The system is reliable and renewable,” she said.

“So there’s a cost associated with that and what was happening was that was work that had to be done — and all of those costs were on the shoulders of people today.”

Wynne noted “this electricity grid is an asset that is going to be used for generations to come.”

“My grandchildren are going to benefit from this asset, so I think it’s fair that we spread the cost of that over that 30-year period,” she said.

“That’s how we made this decision.”

Montreal's first STM electric buses roll out

STM Electric Buses Montreal launch a zero-emission pilot with rapid charging stations on the 36 Monk line from Angrignon to Square Victoria, winter-tested for reliability and aligned with STM's 2025 fully electric fleet plan.

 

Key Points

STM's pilot deploys zero-emission buses with charging on the 36 Monk line, aiming for a fully electric fleet by 2025.

✅ 36 Monk route: Angrignon to Square Victoria with rapid charging

✅ Winter-tested performance; 15-25 km range per charge

✅ Quebec-built: motors Boucherville; buses Saint-Eustache

 

The first of three STM electric buses are rolling in Montreal, similar to initiatives with Vancouver electric buses elsewhere in Canada today.

The test batch is part of the city's plan to have a fully electric fleet by 2025, mirroring efforts such as St. Albert's electric buses in Alberta as well.

Over the next few weeks, one bus at a time will be put into circulation along the 36 Monk line, a rollout approach similar to Edmonton's first electric bus efforts in that city, going from Angrignon Metro station to Square Victoria Metro station. 

Rapid charging stations have been set up at both locations, a model seen in TTC's battery-electric rollout to support operations, so that batteries can be charged during the day between routes. The buses are also going to be fully charged at regular charging stations overnight.

Each bus can run from 15 to 25 kilometres on a single charge. The Monk line was chosen in part for its length, around 11 kilometres.

The STM has been testing the electric buses to make sure they can stand up to Montreal's harsh winters, drawing on lessons from peers such as the TTC electric bus fleet in Toronto, and now they are ready to take on passengers.

 

Keeping it local

The motors were designed in Boucherville, and the buses themselves were built in Saint-Eustache.

No timeline has been set for when the STM will be ready to roll out the whole fleet, but Montreal Mayor Denis Coderre, who was on hand at Tuesday's unveiling, told reporters he has confidence in the $11.9-million program.

"We start with three. Trust me, there will be more." said Coderre.

EPA moves to rewrite limits for coal power plant wastewater

EPA Wastewater Rule Rollback signals a move to rewrite 2015 Clean Water Act guidelines for coal-fired power plants, easing wastewater rules as heavy metals, mercury, lead, arsenic, and selenium threaten rivers, lakes, public health.

 

Key Points

A planned EPA rewrite of 2015 wastewater limits for coal plants, weakening protections against toxic heavy metals.

✅ Targets 2015 Clean Water Act wastewater guidelines

✅ Affects coal-fired steam electric power plants

✅ Raises risks from mercury, lead, arsenic, selenium

 

The Environmental Protection Agency says it plans to scrap an Obama-era measure limiting water pollution from coal-fired power plants, mirroring moves to replace the Clean Power Plan elsewhere in power-sector policy.

A letter from EPA Administrator Scott Pruitt released Monday as part of a legal appeal and amid a broader rewrite of NEPA rules said he will seek to revise the 2015 guidelines mandating increased treatment for wastewater from steam electric power-generating plants.

Acting at the behest of energy groups and electric utilities who opposed the stricter standards, Pruitt first moved in April to delay implementation of the new guidelines. The wastewater flushed from the coal-fired plants into rivers and lakes typically contains traces of such highly toxic heavy metals as lead, arsenic, mercury and selenium.

“After carefully considering your petitions, I have decided that it is appropriate and in the public interest to conduct a rulemaking to potentially revise (the regulations),” Pruitt wrote in the letter addressed to the pro-industry Utility Water Act Group and the U.S. Small Business Administration.

Pruitt’s letter, dated Friday, was filed Monday with the Fifth Circuit U. S. Court of Appeals in New Orleans, which is hearing legal challenges of the wastewater rule. With Pruitt now moving to rewrite the standards, EPA has asked to court to freeze the legal fight.

While that process moves ahead, EPA’s existing guidelines from 1982 remian in effect. Those standards were set when far less was known about the detrimental impacts of even tiny levels of heavy metals on human health and aquatic life.

“Power plants are by far the largest offenders when it comes to dumping deadly toxics into our lakes and rivers,” said Thomas Cmar, a lawyer for the legal advocacy group Earthjustice. “It’s hard to believe that our government officials right now are so beholden to big business that they are willing to let power plants continue to dump lead, mercury, chromium and other dangerous chemicals into our water supply.”

EPA estimates that the 2015 rule, if implemented, would reduce power plant pollution, consistent with new pollution limits proposed for coal and gas plants, by about 1.4 billion pounds a year. Only about 12 per cent of the nation’s steam electric power plants would have to make new investments to meet the higher standards, according to the agency.

Utilities would need to spend about $480 million on new wastewater treatment systems, resulting in about $500 million in estimated public benefits, such as fewer incidents of cancer and childhood developmental defects.

Premier warns NDP, Greens that delaying Site C dam could cost $600M

Site C Project Delay raises BC Hydro costs as Christy Clark warns $600 million impact; NDP and Greens seek BCUC review of the hydroelectric dam on the Peace River, challenging evictions and construction contracts.

 

Key Points

A potential slowdown of B.C.'s Site C dam, risking $600M overruns, evictions, and schedule delays pending a BCUC review.

✅ Clark warns $600M cost if river diversion slips a year

✅ NDP-Green seek BCUC review; request to pause contracts, evictions

✅ Peace River hydro dam; schedule critical to budget, ratepayers

 

Premier Christy Clark is warning the NDP and Greens that delaying work on the Site C project in northeast British Columbia could cost taxpayers $600 million.

NDP Leader John Horgan wrote to BC Hydro last week asking it to suspend the evictions of two homeowners and urging it not to sign any new contracts on the $8.6-billion hydroelectric dam until a new government has gained the confidence of the legislature.

But Clark says in letters sent to Horgan and Green Leader Andrew Weaver on Tuesday that the evictions are necessary as part of a road and bridge construction project that are needed to divert a river in September 2019.

Any delay could postpone the diversion by a year and cost taxpayers hundreds of millions of dollars, she says.

“With a project of this size and scale, keeping to a tight schedule is critical to delivering a completed project on time and on budget,” she says. “The requests contained in your letter are not without consequences to the construction schedule and ultimately have financial ramifications to ratepayers.”

The premier has asked Horgan and Weaver to reply by Saturday on whether they still want to put the evictions on hold.

She also asks whether they want the government to issue a “tools down” request to BC Hydro on other decisions that she says are essential to maintaining the budget and construction schedule.

An agreement between the NDP and Green party was signed last week that would allow the New Democrats to form a minority government, ousting Clark's Liberals.

The agreement includes a promise to refer the Site C project to the B.C. Utilities Commission to determine its economic viability.

Some analysts argue that better B.C.-Alberta power integration could improve climate outcomes and market flexibility.

But Clark says the project is likely to progress past the “point of no return” before a review can be completed.

Clark did not define what she meant by “point of no return,” nor did she explain how she reached the $600-million figure. Her press secretary Stephen Smart referred questions to BC Hydro, which did not immediately respond.

During prolonged drought conditions, BC Hydro has had to adapt power generation across the province, affecting planning assumptions.

In a written response to Clark, Weaver says before he can comment on her assertions he requires access to supporting evidence, including signed contracts, the project schedule and potential alternative project timelines.

“Please let me express my disappointment in how your government is choosing to proceed with this project,” he says.

“Your government is turning a significant capital project that potentially poses massive economic risks to British Columbians into a political debate rather than one informed by evidence and supported by independent analysis.”

The dam will be the third on the Peace River, flooding an 83-kilometre stretch of valley, and local First Nations, landowners and farmers have fiercely opposed the project.

Construction began two years ago.

A report written by University of British Columbia researchers in April argued it wasn't too late to press pause on the project and that the electricity produced by Site C won't be fully required for nearly a decade after it's complete.

Coal comeback unlikely after Paris climate pact withdrawal, says utility CEO

US Shift From Coal to Renewables accelerates as natural gas, solar, and wind power gain market share, driven by the Paris climate agreement, clean energy mandates, smart grid upgrades, and energy efficiency.

 

Key Points

An industry trend where power producers replace coal with natural gas, solar, and wind to meet clean energy goals.

✅ Shareholders and customers demand cleaner power portfolios

✅ Natural gas, solar, and wind outcompete coal on cost and risk

✅ Smart grid and efficiency investments reduce emissions further

 

President Trump once again promised to revive the U.S. coal industry when he announced his intention to withdraw the U.S. from the Paris climate agreement.

But that reversal seems as unlikely as ever as electric power producers, the biggest consumers of coal in the U.S., continue to shift to natural gas and renewable energy sources like solar and wind power. In 2016, natural gas became the leading fuel for U.S. electricity generation for the first time, responsible for 33.8% of the output, compared with 30.4% for coal, according to the U.S. Energy Information Administration, even as coal-fired generation was projected to rise in 2021 in the short term.

Nick Akins, the CEO of American Electric Power, one of the largest utilities in the U.S., says the preference for gas, renewables and energy efficiency, will only grow in response to increasing demands from shareholders and customers for cleaner energy, regardless of changes in national energy policy.

With 5.4 million customers in 11 states, AEP plans to spend $1.5 billion on renewable energy from 2017 through 2019, and $13 billion on transmission and distribution improvements, including new “smart” technologies that will make the grid more resilient and efficient, AEP says.

We spoke with Akins on Thursday, just after Trump’s announcement. The transcript is edited for length and clarity.

 

What do you think of Trump’s decision to pull the U.S. from the climate agreement?

I don’t think it’s unexpected. He obviously made the point that he’s willing to renegotiate or have further dialogue about it. That’s a good sign. From our perspective, we’re going to continue along the path we’re already on toward a cleaner energy economy.

 

AEP and the U.S. electric power industry in general have been moving away from coal in favor of natural gas and renewable energy. Will this decision by the Trump administration have any impact on that trend?

If you look at our resource plans in all of the states we serve, they are focused on renewables, natural gas and transmission, as declining returns from coal generation pressure investment choices across the industry. And big-data analytics improves the efficiency of the grid, so energy efficiency is obviously a key component, as Americans use less electricity overall.

Our carbon dioxide emissions in 2016 were 44% below 2000 levels, and that progress will continue with the additions of more renewables, energy efficiency and natural gas.

So, you don’t see coal making a comeback at AEP or other utilities?

No, I don’t think so. … You wouldn’t make a decision (to build a coal power plant) at this point because it’s heavily capital-intensive, and involves a longer-term process and risk to build. And, of course, you can add renewables that are very efficient and natural gas that’s efficient and much less expensive and risky, in terms of construction and operation.

 

Do you plan to close any more coal-powered plants soon? 

I suspect we’ll see some more retirements in the future, with coal and nuclear closures test just transition in many communities, and as we progress towards that cleaner energy economy, and consider the expectations of our customers and shareholders for us to mitigate risk, you’ll continue to see that happen.

But on the other hand, I want to make sure there’s an understanding that coal will remain a part of the portfolio, even though in rare cases new coal plants are still being built where options are limited, but it will be of a lesser degree because of these other resources that are available to us now that weren’t available to us just a few years ago.

 

Do you find yourself under more or less pressure from customers and shareholders to move to cleaner forms of energy?

I think there’s more pressure. Investors are looking for the sustainability of the company going forward and mitigation of risks … From a customer standpoint, we have some large customers interested in moving into our service territory who are looking for cleaner energy, and want to know if we’re focused on that. Some of them want to be supplied entirely by those clean sources. So, we’re clearly responding to our customers’ and our shareholders’ expectations.

 

What’s the solution for workers at coal mines and coal power plants who have lost their jobs?

Certainly, the skill sets of employees in mining and around machinery are transferable to other areas of manufacturing, like aerospace and defense. So, we’re really focusing on economic-development efforts in our service territories … particularly in the coal states … to bring coal miners back to work, not necessarily in coal mines but certainly (in manufacturing).

Unilorin develops device to check electricity theft

Ilorin Electricity Theft Device delivers remote monitoring and IoT-based detection for smart meters, identifying bypassed prepaid meters, triggering disconnects, and alerting the utility control room to curb distribution losses and energy theft.

 

Key Points

A prototype IoT system that detects electricity theft, enables remote disconnection, and alerts utility control rooms.

✅ Remote monitoring flags bypassed prepaid meters.

✅ Sends alerts to utility control room with customer details.

✅ Enables safe remote cut-off to reduce distribution losses.

 

The Department of Electrical and Electronics Engineering, University of Ilorin, has unveiled a prototype anti-theft device capable of remotely monitoring and detecting customers stealing electricity.

The Acting Head of the Department, Dr Mudathir Akorede told newsmen on Tuesday in Ilorin that the device could also cut off electricity supply to the premises of customers stealing electricity.

”This will simultaneously send a message to the utility control room, and in light of rising ransomware attacks targeting power systems, to alert the system operator with such customer’s details displayed on the control panel,” he said.

Akorede said that processes of filing application for patenting the invention, in line with emerging IoT security standards for the electricity sector, had commenced through the university’s Laboratory to Product Centre.

The don explained that the device was developed by himself and some students of the Department, reflecting how university teams contribute to innovations like generating electricity from falling snow in the field.

Akorede said, “I gave the project to my undergraduate students; they carried out the project to a level and I took it over and brought it to a level that was up to standard.”

The Don further said,”The invention is now up to the standard that it can be patented.

“I have brought this to the attention of the Ibadan Electricity Distribution Company, although not officially, but if adopted, and as utilities pursue digitizing the grid strategies, the device would enable distribution companies to cut their commercial losses substantially.”

He said that the idea followed the discovery that most people use electricity without paying for it.

”A lot of people that have been able to get the prepaid meter, even though they can afford to pay their bills, still want to bypass this thing to steal electricity and this is not helping the companies.

“It is not helping all of us as a whole. If the industry should collapse, with emerging cyber weapons that can disrupt power grids underscoring systemic risks, everybody would bear the brunt of that problem and that is why the consumers too have to share out of the problem

“But this is not to say that distribution companies also do not have their share of the blame by not wanting to take on responsibilities such as faulty transformers.”
