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.

Australia electricity market: Plan to avoid threats to electricity supply

National Electricity Market review calls for clear coal-fired closure schedules to safeguard energy security, backing a technology-agnostic clean energy and low emissions target with tradeable certificates to stabilise prices and support a smoother transition.

 

Key Points

A review proposing orderly coal closures and a technology-agnostic clean energy target to protect grid reliability.

✅ Mandates advance notice of coal plant closure schedules

✅ Supports clean energy and low emissions target with certificates

✅ Aims to stabilise prices and ensure system security

 

THE Latrobe Valley’s coal-fired power stations could be forced to give details of planned closures well in advance to help governments avoid major threats to electricity supply, amid an AEMO warning on reduced reserves across the grid.

The much-anticipated review of the national electricity market, to be released on Friday, will outline the need for clear schedules for the closure of coal-fired power stations to avoid rushed decisions on ­energy security.

It is believed the Turnbull government, which has ruled out taxpayer-funded power plants in the current energy debate, will move toward either a clean-energy or a low-emissions target that aims to bolster power security while reducing household bills and emissions.

The system, believed to be also favoured by industry, would likely provide a more stable transition to clean energy by engaging with the just transition concept seen in other markets, because coal-fired power would not be driven out of the market as quickly.

Sources said that would lead to greater investment in the energy sector, a surplus of production and, as seen in Alberta's shift to gas and price cap debate driving market changes, a cut in prices.

It is likely most coal-fired power stations, such as Yallourn and Loy Yang in the Latrobe Valley, would see out their “natural lives” under the government’s favoured system, rather than be forced out of business by an EIS.

The new target would be separate from the Renewable Energy Target which have come under fire because of ad hoc federal and state targets.

The Herald Sun has been told the policy would provide tradeable clean-energy certificates for low-emissions generation, such as wind, solar and gas and coal which used carbon capture and storage technology.

Energy retailers and large industrial users would then be ­required to source a mandated amount of certified clean power.

Federal Energy Minister Josh Frydenberg has repeatedly said any solution must be “technology agnostic” including gas, renewable energy and coal, amid ongoing debates over whether to save or close nuclear plants such as the Three Mile Island debate in other markets.

Energy Networks Australia’s submission to the review, chaired by Chief Scientist Alan Finkel, acknowledged the challenges in identifying potential generation closures, particularly with uncertain and poorly integrated state and national carbon policy settings.

The group said given the likelihood of further closures of coal fired generation units a new mechanism was needed to better manage changes in the generation mix, well in advance of the closure of the plant.

It said the implications for system stability were “too significant” to rely on the past short-term closures, such as Hazelwood, particularly when the amount of power generated could drive energy security to “tipping point”.

Seasonal power rates could cause consumer backlash

NB Power seasonal electricity rates face backlash amid smart grid delays, meter reading limits, and billing dispute risks, as consultants recommend AMI smart meters for accurate winter-summer pricing, time-of-use alignment, and consumer protection.

 

Key Points

NB Power seasonal electricity rates raise winter prices and lower summer prices to match costs, using accurate AMI metering.

✅ Requires midnight meter reads without AMI, increasing billing disputes.

✅ Shifts costs to electric-heat homes during high winter demand.

✅ Recommended to wait for smart grid AMI for time-of-use accuracy.

 

A consultant hired by NB Power is warning of significant consumer "backlash" if the utility is made to establish seasonal rates for electricity, as seen in B.C. and Quebec smart meter disputes among customers.

The consultant's report even suggests customers might have to read their own power meters at midnight twice a year — on April Fool's and Halloween — to make the system work.

"Virtually all bills will have errors ... billing disputes can be expected to increase, as seen in a $666 smart meter bill in N.S. that raised concerns, possibly dramatically, and there will be no means of resolving disputes in a satisfactory way," reads a report by Elenchus Research Associates that was commissioned by NB Power and filed with the Energy and Utilities Board on Thursday.

NB Power is in the middle of a year-long "rate design" review ordered by the EUB that is focused in part on whether the utility should charge lower prices for electricity in the summer and higher prices in the winter to better reflect the actual cost of serving customers.

New network of meters needed

Elenchus was asked to study how that might work but the company is arguing against any switch until NB Power upgrades its entire network of power meters, given old meters in N.B. have raised concerns.

Elenchus said seasonal rates require an accurate reading of every customer's power meter at midnight on March 31 and again on Oct. 31, the dates when power rates would switch between winter and summer prices.

But NB Power does not have the sophisticated infrastructure in place to read meters remotely, or the manpower to visit every customer location on the same day, so Elenchus said the utility would have to guesstimate bills or rely on the technical savvy and honesty of customers themselves.

"Customers could be asked to read their own meters late in the day on March 31 (and October 31)," suggested the report. "Aside from the obvious inconvenience and impracticality of that approach, NB Power would have no means of verifying the customers' meter reads."

Residential customers would see hike

Another looming controversy with seasonal rates is that it would raise costs for residential customers, especially to those who heat with electricity, a pressure seen with a 14% rate increase in Nova Scotia recently.

Elenchus estimated seasonal rates would add nearly $6 million to the cost of residential bills overall, with the largest increases flowing to those with baseboard heat.

Electric heat customers consume the majority of their power during the five months that would have the highest prices and Elenchus said that is another reason to wait for better power meters before proceeding.

NB Power has an ambitious plan to upgrade meters and related infrastructure as part of its transformation to a "smart grid," but it is a multi-year plan.

Once in place the utility would be able to read meters remotely hour to hour, allowing power rates to be adjusted for times of the day and days of the week as well as seasonally.

Consumers will also have in-home pricing and consumption displays to help them manage their bills.

Elenchus said waiting for those meters will give electric heat customers a chance to avoid higher seasonal costs by letting them shift power consumption to lower-priced parts of the day.

"The introduction of seasonal rates would be more acceptable once AMI (advanced metering infrastructure) has been deployed," concludes the report.

A final hearing on NB Power's rate design, where seasonal rates and other changes will be considered, amid a power market overhaul debate in Alberta that industry is watching, is scheduled for next April.

UK must be ready for rise of electric vehicles, says ABB chief

UK EV Charging Infrastructure is accelerating as ABB and Formula E spotlight fast charging, smart grids, and public stations, preparing Britain for mass electric vehicle adoption with expanded capacity, reliable connectors, and nationwide coverage.

 

Key Points

The UK network of charge points, grid capacity, and services enabling secure, scalable electric vehicle adoption.

✅ ABB urges rapid rollout of fast chargers and smart grid upgrades

✅ National Grid forecasts up to 9m EVs by 2030 in the UK

✅ Government GBP 400m investment targets reliable nationwide coverage

 

The UK should speed up preparations for the rise of electric vehicles, according to the chief executive of ABB, the world’s largest supplier of fast-charging points.

Speaking as the Switzerland-based engineering firm became the first official sponsor of the electric street racing series Formula E, Ulrich Spiesshofer predicted a flood of consumer take-up of plug-in cars, noting how EV inquiries surged in the UK during a recent fuel supply crisis.

And he added his voice to warnings that Britain must move faster to make sure owners of electric vehicles are not stymied by a shortage of charging bays or cost concerns among consumers.

“E-mobility is unstoppable, it’s just a question of how fast and how deep it will be deployed,” he said. “The UK has a big population that really wants to contribute to a greener, more sustainable world. But there’s always a question of whether it’s quick enough. In the next couple of years, it’s in the interest of everybody to make sure the infrastructure is coming up.”

 

How green are electric cars?

He said this would include adding to the UK’s network of electric charging points, as well as ensuring enough energy capacity so that the grid can cope with rising demand.

There are 14,344 charging connectors in the UK, according to ZapMap, which charts the scale of the UK’s network.

Those charging points served around 132,000 plug-in vehicles at the end of 2017, but the National Grid has predicted that the number of electric cars could surge to 9m by 2030.

“In the next couple of years, it’s in the interest of everybody to make sure the infrastructure is coming up,” said Spiesshofer.

He welcomed the government’s budget pledge to spend £400m on improving the UK’s charging point network but warned that the power grid also needed to be ready to meet the increased demand, which many argue is manageable with proper management approaches.

Electric cars have been forecast to add about 18 gigawatts of power demand to the grid, the equivalent of six Hinkley Point C nuclear power stations.

Spiesshofer said he hoped ABB’s sponsorship of Formula E, which will last until 2025, would help spur interest in electric cars and lead to technological breakthroughs, even as the US EV boom tests charging capacity elsewhere.

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.”

Renewables generated more electricity than brown coal over summer, report finds

Renewables Beat Brown Coal in Australia, as solar and wind surged to nearly 10,000 GWh, stabilizing the grid with battery storage during peak demand, after Hazelwood's closure, Green Energy Markets reported.

 

Key Points

It describes a 2017-18 summer when solar, wind, and storage generated more electricity than brown coal in Australia.

✅ Solar and wind hit nearly 10,000 GWh in summer 2017-18

✅ Brown coal fell to about 9,100 GWh after Hazelwood closure

✅ Batteries stabilized peak demand; Tesla responded in milliseconds

 

Renewable energy generated more electricity than brown coal during Australia’s summer for the first time in 2017-18, according to a new report by Green Energy Markets.

Continued growth in solar, as part of Australia's energy transition, pushed renewable generation in Australia to just under 10,000 gigawatt hours between December 2017 and February 2018. With the Hazelwood plant knocked out of the system last year, brown coal’s output in the same period was just over 9,100 GWh.

Renewables produced 40% more than gas over the period, and was exceeded only by black coal, reflecting trends seen in U.S. renewables surpassing coal in 2022.

#google#

The report, commissioned by GetUp, found renewables were generating particularly large amounts of electricity when it was most needed, producing 32% more than brown coal during summer between 11am and 7pm, when demand peaks.

 

Coal in decline: an energy industry on life support

Solar in particular was working to support the system, on average producing more than Hazelwood was capable of producing between 9am and 5pm.

A further 5,000 megawatts of large-scale renewables projects was under construction in February, supporting 17,445 jobs, while renewables became the second-most prevalent U.S. electricity source in 2020.

GetUp’s campaign director, Miriam Lyons, said the latest renewable energy index showed renewables were keeping the lights on while coal became increasingly unreliable, a trend echoed as renewables surpassed coal in the U.S. in recent years.

“Over summer renewables kept houses cool and lights on during peak demand times when people needed electricity most,” Lyons said. “Meanwhile dirty old coal plants are becoming increasingly unreliable in the heat.

“These ageing clunkers failed 36 times over summer.

“Clean energy rescued people from blackouts this summer. When the clapped-out Loy Yang coal plant tripped, South Australia’s giant Tesla battery reacted in milliseconds to keep the power on.

“It’s clear that a smart electricity grid based on a combination of renewable energy and storage is the best way to deliver clean, affordable energy for all Australians.”

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.
