Anger erupts over conflicting coal bed decisions

CO2 Tax for UK Offshore Energy Efficiency can accelerate adoption of aero-derivative gas turbines, flare gas recovery, and combined cycle power, reducing emissions on platforms like Equinor's Mariner and supporting net zero goals.

Key Points

A carbon price pushing operators to adopt efficient turbines, flare recovery, and combined cycle to cut emissions.

✅ Aero-derivative turbines beat industrial units on efficiency

✅ Flare gas recovery cuts routine flaring and fuel waste

✅ Combined cycle raises efficiency and lowers emissions

By Tom Baxter

The recent Energy Voice article from the Equinor chairman concerning the Mariner project heralding a ‘significant point of reference’ for growth highlighted the energy efficiency achievements associated with the platform.

I view energy efficiency as a key enabler to net zero, and alongside this the UK must start large-scale storage to meet system needs; it is a topic I have been involved with for many years.

As part of my energy efficiency work, I investigated Norwegian practices and compared them with the UK.

There were many differences, here are three;

1. Power for offshore installations is usually supplied from gas turbines burning fuel from the oil and gas processing plant, and even as the UK's offshore wind supply accelerates, installations convert that to electricity or couple the gas turbine to a machine such as a gas compressor.

There are two main generic types of gas turbine – aero-derivative and industrial. As the name implies aero-derivatives are aviation engines used in a static environment. Aero-derivative turbines are designed to be energy efficient as that is very import for the aviation industry.

Not so with industrial type gas turbines; they are typically 5-10% less efficient than a comparable aero-derivative.

Industrial machines do have some advantages – they can be cheaper, require less frequent maintenance, they have a wide fuel composition tolerance and they can be procured within a shorter time frame.

My comparison showed that aero-derivative machines prevailed in Norway because of the energy efficiency advantages – not the case in the UK where there are many more offshore industrial gas turbines.

2. Offshore gas flaring is probably the most obvious source of inefficient use of energy with consequent greenhouse gas emissions.

On UK installations gas is always flared due to the design of the oil and gas processing plant.

Though not a large quantity of gas, a continuous flow of gas is routinely sent to flare from some of the process plant.

In addition the flare requires pilot flames to be maintained burning at all times and, while Europe explores electricity storage in gas pipes, a purge of hydrocarbon gas is introduced into the pipes to prevent unsafe air ingress that could lead to an explosive mixture.

On many Norwegian installations the flare system is designed differently. Flare gas recovery systems are deployed which results in no flaring during continuous operations.

Flare gas recovery systems improve energy efficiency but they are costly and add additional operational complexity.

3. Returning to gas turbines, all UK offshore gas turbines are open cycle – gas is burned to produce energy and the very hot exhaust gases are vented to the atmosphere. Around 60 -70% of the energy is lost in the exhaust gases.

Some UK fields use this hot gas as a heat source for some of the oil and gas treatment operations hence improving energy efficiency.

There is another option for gas turbines that will significantly improve energy efficiency – combined cycle, and in parallel plans for nuclear power under the green industrial revolution aim to decarbonise supply.

Here the exhaust gases from an open cycle machine are taken to a separate turbine. This additional turbine utilises exhaust heat to produce steam with the steam used to drive a second turbine to generate supplementary electricity. It is the system used in most UK power stations, even as UK low-carbon generation stalled in 2019 across the grid.

Open cycle gas turbines are around 30 – 40% efficient whereas combined cycle turbines are typically 50 – 60%. Clearly deploying a combined cycle will result in a huge greenhouse gas saving.

I have worked on the development of many UK oil and gas fields and combined cycle has rarely been considered.

The reason being is that, despite the clear energy saving, they are too costly and complex to justify deploying offshore.

However that is not the case in Norway where combined cycle is used on Oseberg, Snorre and Eldfisk.

What makes the improved Norwegian energy efficiency practices different from the UK – the answer is clear; the Norwegian CO2 tax.

A tax that makes CO2 a significant part of offshore operating costs.

The consequence being that deploying energy efficient technology is much easier to justify in Norway when compared to the UK.

Do we need a CO2 tax in the UK to meet net zero – I am convinced we do. I am in good company. BP, Shell, ExxonMobil and Total are supporting a carbon tax.

Not without justification there has been much criticism of Labour’s recent oil tax plans, alongside proposals for state-owned electricity generation that aim to reshape the power market.

To my mind Labour’s laudable aims to tackle the Climate Emergency would be much better served by supporting a CO2 tax that complements the UK's coal-free energy record by strengthening renewable investment.

ATCO Electric administrative penalty underscores an Alberta Utilities Commission probe into a sole-sourced First Nation contract, Jasper transmission line overpayments, and nondisclosure to ratepayers, sparked by a whistleblower and pending settlement approval.

Key Points

A $31M AUC settlement over alleged overpayment, sole-sourcing, and nondisclosure tied to a Jasper transmission line.

✅ $31M administrative penalty; AUC settlement pending approval

✅ Sole-sourced First Nation contract to protect related ATCO deal

✅ Overpayment concealed when seeking recovery from ratepayers

Regulated Alberta utility ATCO Electric has agreed to pay a $31 million administrative penalty after an Alberta Utilities Commission utilities watchdog investigation found it deliberately overpaid a First Nation group for work on a new transmission line, and then failed to disclose the reasons for it when it applied to be reimbursed by ratepayers for the extra cost.

An agreed statement of facts contained in a settlement agreement between ATCO Electric Ltd. and the commission's enforcement staff says the company sole-sourced a contract in 2018 for work that was necessary for an electric transmission line to Jasper, Alta., even as BC Hydro marked a Site C transmission line milestone elsewhere.

The company that won the contract was co-owned by the Simpcw First Nation in Barriere, B.C., while debates over a First Nations electricity line in Ontario underscore related issues, and the agreement says one of the reasons for the sole-sourcing was that another of Calgary-based ATCO's subsidiaries had a prior deal with the First Nation for infrastructure projects that included the provision of work camps on the Trans Mountain Pipeline expansion project.

The statement of facts says ATCO Electric feared that if it didn't grant the contract to the First Nation group and instead put the work to tender, amid legal pressures such as a treaty rights challenge, the group might back out of its deal with ATCO Structures and Logistics and partner with another, non-ATCO company on the Trans Mountain work.

The agreed statement says ATCO Electric paid several million dollars more than market value for some of the Jasper line work, while a Manitoba-Minnesota line delay was being weighed in another jurisdiction, and staff attempted to conceal the reasons for the overpayment when they sought to recover the extra money from Alberta consumers.

It states the investigation was sparked by a whistleblower, and notes the agreement between the utility commission's enforcement staff and ATCO Electric must still be approved by the Alberta Utilities Commission, a process comparable to hearings that consider oral traditional evidence on interprovincial lines.

The commission must be satisfied the settlement is in the public interest, a consideration often informed by concerns from Site C opponents in other regions.

U.S. Power Grid Supply Shortages strain reliability as heat waves, hurricanes, and drought drive peak demand; transformer scarcity, gas constraints, and renewable delays raise outage risks across ERCOT and MISO, prompting FERC warnings.

Key Points

They are equipment and fuel constraints that, amid extreme weather and peak demand, elevate outage risks.

✅ Transformer shortages delay storm recovery and repairs.

✅ Record gas burn, low hydro tighten generation capacity.

✅ ERCOT and MISO warn of rolling outages in heat waves.

U.S. power companies are facing supply crunches amid the U.S. energy crisis that may hamper their ability to keep the lights on as the nation heads into the heat of summer and the peak hurricane season.

Extreme weather events such as storms, wildfires and drought are becoming more common in the United States. Consumer power use is expected to hit all-time highs this summer, reflecting unprecedented electricity demand across the Eastern U.S., which could strain electric grids at a time when federal agencies are warning the weather could pose reliability issues.

Utilities are warning of supply constraints for equipment, which could hamper efforts to restore power during outages. They are also having a tougher time rebuilding natural gas stockpiles for next winter, after the Texas power system failure highlighted cold-weather vulnerabilities, as power generators burn record amounts of gas following the shutdown of dozens of coal plants in recent years and extreme drought cuts hydropower supplies in many Western states.

"Increasingly frequent cold snaps, heat waves, drought and major storms continue to challenge the ability of our nation’s electric infrastructure to deliver reliable affordable energy to consumers," Richard Glick, chairman of the U.S. Federal Energy Regulatory Commission (FERC), said earlier this month.

Federal agencies responsible for power reliability like FERC have warned that grids in the western half of the country could face reliability issues this summer as consumers crank up air conditioners to escape the heat, with nationwide blackout risks not limited to Texas. read more

Some utilities have already experienced problems due to the heat. Texas' grid operator, the Electric Reliability Council of Texas (ERCOT), was forced to urge customers to conserve energy as the Texas power grid faced another crisis after several plants shut unexpectedly during an early heat wave in mid-May. read more

In mid-June, Ohio-based American Electric Power Co (AEP.O) imposed rolling outages during a heat wave after a storm damaged transmission lines and knocked out power to over 200,000 homes and businesses.

The U.S. Midwest faces the most severe risk because demand is rising while nuclear and coal power supplies have declined. read more

The Midcontinent Independent System Operator (MISO), which operates the grid from Minnesota to Louisiana, warned that parts of its coverage area are at increased risk of temporary outages to preserve the integrity of the grid.

Supply-chain issues have already delayed the construction of renewable energy projects across the country, and the aging U.S. grid is threatening progress on renewables and EVs. Those renewable delays coupled with tight power in the Midwest prompted Wisconsin's WEC Energy Group Inc (WEC.N) and Indiana's NiSource Inc (NI.N) to delay planned coal plant shutdowns in recent months.

BRACING FOR SUPPLY SHORTAGES
Utility operators are conserving their inventory of parts and equipment as they plan to prevent summer power outages during severe storms. Over the last several months, that means operators have been getting creative.

"We’re doing a lot more splicing, putting cables together, instead of laying new cable because we're trying to maintain our new cable for inventory when we need it," Nick Akins, chief executive of AEP, said at the CERAWeek energy conference in March.

Transformers, which often sit on top of electrical poles and convert high-voltage energy to the power used in homes, are in short supply.

New Jersey-based Public Service Enterprise Group Inc (PSEG) (PEG.N) Chief Executive Ralph Izzo told Reuters the company has had to look at alternate supply options for low voltage transformers.

"You don’t want to deplete your inventory because you don't know when that storm is coming, but you know it's coming," Izzo said.

Some utilities are facing waiting times of more than a year for transformer parts, the National Rural Electric Cooperative Association and the American Public Power Association told U.S. Energy Secretary Jennifer Granholm in a May letter.

Summer is just starting, but U.S. weather so far this year has already been about 21% warmer than the 30-year norm, according to data provider Refinitiv.

"If we have successive days of 100-degree-heat, those pole top transformers, they start popping like Rice Krispies, and we would not have the supply stack to replace them," Izzo said.

Alberta Electricity Rate Cap stays despite carbon tax repeal, keeping the Regulated Rate Option at 6.8 cents/kWh. Levy funds cover market gaps as the UCP reviews NDP policies to maintain affordable utility bills.

Key Points

Program capping RRO power at 6.8 cents/kWh, using levy funds to offset market prices while the UCP reviews policy.

✅ RRO cap fixed at 6.8 cents/kWh for eligible customers

✅ Levy funds pay generators when market prices exceed the cap

✅ UCP reviewing NDP policies to ensure affordable rates

Alberta's carbon tax has been cancelled, but a consumer price cap on electricity — which the levy pays for — is staying in place for now.

June electricity rates are due out on Monday, about four days after the new UCP government did away with the carbon charge on natural gas and vehicle fuel.

Part of the levy's revenue was earmarked by the previous NDP government to keep power prices at or below 6.8 cents per kilowatt hour under new electricity rules set by the province.

"The Regulated Rate Option cap of 6.8 cents/kWh was implemented by the previous government and currently remains in effect. We are reviewing all policies put in place by the former government and will make decisions that ensure more affordable electricity rates for job-creators and Albertans," said a spokesperson for Alberta's energy ministry in an emailed statement.

Albertans with regulated rate contracts and all City of Medicine Hat utility customers only pay that amount or less, though some Alberta ratepayers have faced deferral-related arrears.

If the actual market price rises above that, the difference is paid to generators directly from levy funds, a buffer that matters as experts warn prices are set to soar later this year.

The government has paid more than $55 million to utilities over the past year ending in March 2019, due to that electricity price cap being in place.

Alberta Energy says the price gap program will continue, at least for the time being, amid electricity policy changes being considered.

Octopus Energy and DTEK Partnership explores licensing the Kraken platform to rebuild Ukraine's power grid, enabling real-time analytics, smart-home integration, renewable energy orchestration, and distributed resilience amid ongoing attacks on critical energy infrastructure.

Key Points

Collaboration to deploy Kraken and renewables to modernize Ukraine's grid with analytics, smart control, and resilience.

✅ Kraken licensing for grid operations and customer analytics

✅ Shift to distributed solar, wind, and smart-home devices

✅ Real-time monitoring to mitigate outages and cyber risks

Octopus Energy, a prominent UK energy firm, has begun preliminary conversations with Ukraine's DTEK regarding potential collaboration to refurbish Ukraine's heavily damaged electric infrastructure as ongoing strikes threaten the power grid across the country.

Persistent assaults by Russia on Ukraine's power network, including a five-hour attack on Kyiv's grid, have led to significant electricity shortages in numerous regions.

Octopus Energy, the largest electricity and second-largest gas supplier in the UK, collaborates with energy firms in 17 countries using its Kraken software platform, and Ukraine joined Europe's power grid with unprecedented speed to bolster resilience. This platform is currently being trialled by the Abu Dhabi National Energy Company (Taqa) for power and water customers in the UAE.

A spokesperson from Octopus revealed to The National that the company is "in the early stages of discussions with DTEK to explore potential collaborative opportunities.”

One of the possibilities being considered is licensing Octopus's Kraken technology platform to DTEK, a platform that presently serves 54 million customer accounts globally.

Russian drone and missile attacks, which initially targeted Ukrainian ports and export channels last summer, shifted focus to energy infrastructure by October, ahead of the winter season as authorities worked to protect electricity supply before winter across the country.

These initial talks between Octopus CEO Greg Jackson and DTEK CEO Maxim Timchenko took place at the World Economic Forum in Davos, set against the backdrop of these ongoing challenges.

DTEK, Ukraine's leading private energy provider, might integrate Octopus's advanced Kraken software to manage and optimize data systems ranging from large power plants to smart-home devices, with a growing focus on protecting the grid against emerging threats.

Kraken is described by Octopus as a comprehensive technology platform that supports the entire energy supply chain, from generation to billing. It enables detailed analytics, real-time monitoring, and control of energy devices like heat pumps and electric vehicles, underscoring the need to counter cyber weapons that can disrupt power grids as systems become more connected.

Octopus Energy, with its focus on renewable sources, can also assist Ukraine in transitioning its power infrastructure from centralized coal-fired power stations, which are vulnerable targets, to a more distributed network of smaller solar and wind projects.

DTEK, serving approximately 3.5 million customers in the Kyiv, Donetsk, and Dnipro regions, is already engaged in renewable initiatives. The company constructed a wind farm in southern Ukraine within nine months last year and has plans for additional projects in Italy and Croatia.

Emphasizing the importance of rebuilding Ukraine's economy, Timchenko recently expressed at Davos the need for Ukrainian and international companies to work together to create a sustainable future for Ukraine, noting that incidents such as Russian hackers accessed U.S. control rooms highlight the urgency.
