Steeply rising energy prices should soon drive African mobile phone operators to power their base stations with alternative energy sources such as solar or wind, industry executives said.

Africa burns more than 30 million liters of diesel a year to power mobile phone base stations, according to industry group GSMA.

The number of stations without a connection to the electricity grid will only rise as the industry is planning to spend more than $50 billion over five years to bring coverage to remoter areas.

"In Africa, in many markets in this part of the world, there is an abundance of sun, an abundance of wind," Alex Shalaby, CEO of Egyptian mobile carrier Mobinil told Reuters at the sidelines of the ITU Telecom Africa conference in Cairo.

"If there isn't a business case today, there will be once oil is at $200 (a barrel)."

Celtel, the African business of Kuwait's Mobile Telecommunications Co (Zain), is switching a number of sites to a technology similar to the one used in hybrid cars, its Chief Executive Chris Gabriel told Reuters.

"Diesel consumption is a significant cost item. We are changing over a lot of our diesel sites to hybrid sites...you run your diesel generators for eight hours, as an example, it charges up the batteries, the diesel shuts off, the batteries run down," he said.

"You can reduce your diesel consumption by about 55 percent using this technology."

Low-power equipment can do its part to reduce the need for diesel generators, equipment vendors said.

Huawei said its latest base station consumed 47 percent less energy and can be powered by solar panels and a wind turbine, with energy stored in batteries for backup. It also requires less cooling as it can withstand temperatures of up to 55 degrees Celsius.

The total cost of ownership - the combination of initial capital spending and ongoing costs of maintenance and operations - is 30 percent lower, a Huawei product manager said.

Nokia Siemens Networks (NSN) showed a low-power product for covering villages with a mobile phone signal, which can also be powered by solar panels.

Apart from consuming less energy, the capital spending is about a tenth of a normal mobile phone base station, making it an easier business case for rural areas with a low income that generate low revenue, NSN said.

Alberta is a powerhouse for both green energy and fossil fuels

Alberta Renewable Energy Market is accelerating as wind and solar prices fall, corporate PPAs expand, and a deregulated, energy-only system, AESO outlooks, and TIER policy drive investment across the province.

 

Key Points

An open, energy-only Alberta market where wind and solar growth is driven by corporate PPAs, AESO outlooks, and TIER.

✅ Energy-only, deregulated grid enables private investment

✅ Corporate PPAs lower costs and hedge power price risk

✅ AESO forecasts and TIER policy support renewables

 

By Chris Varcoe, Calgary Herald

A few things are abundantly clear about the state of renewable energy in Alberta today.

First, the demise of Alberta’s Renewable Electricity Program (REP) under the UCP government isn’t going to see new projects come to a screeching halt.

In fact, new developments are already going ahead.

And industry experts believe private-sector companies that increasingly want to purchase wind or solar power are going to become a driving force behind even more projects in Alberta.

BluEarth Renewables CEO Grant Arnold, who spoke Wednesday at the Canadian Wind Energy Association conference, pointed out the sector is poised to keep building in the province, even with the end of the REP program that helped kick-start projects and triggered low power prices.

“The fundamentals here are, I think, quite fantastic — strong resource, which leads to really competitive wind prices . . . it’s now the cheapest form of new energy in the province,” he told the audience.

“Alberta is in a fundamentally good place to grow the wind power market.”

Unlike other provinces, Alberta has an open, deregulated marketplace, which create opportunities for private-sector investment and renewable power developers as well.

The recent decision by the Kenney government to stick with the energy-only market, instead of shifting to a capacity market, is seen as positive for Alberta's energy future by renewable electricity developers.

There is also increasing interest from corporations to buy wind and solar power from generators — a trend that has taken off in the United States with players such as Google, General Motors and Amazon — and that push is now emerging in Canada.

“It’s been really important in the U.S. for unlocking a lot of renewable energy development,” said Sara Hastings-Simon, founding director of the Business Renewable Centre Canada, which seeks to help corporate buyers source renewable energy directly from project developers.

“You have some companies where . . . it’s what their investors and customers are demanding. I think we will see in Alberta customers who see this as a good way to meet their carbon compliance requirements.

“And the third motivation to do it is you can get the power at a good price.”

Just last month, Perimeter Solar signed an agreement with TC Energy to supply the Calgary-based firm with 74 megawatts from its solar project near Claresholm.

More deals in the industry are being discussed, and it’s expected this shift will drive other projects forward.

There is increasing interest from corporations to buy solar and wind energy directly from generators.

“The single-biggest change has been the price of wind and solar,” Arnold said in an interview.

“Alberta looks really, really bright right now because we have an open market. All other provinces, for regulatory reasons, we can’t have this (deal) . . . between a generator and a corporate buyer of power. So Alberta has a great advantage there.”

These forces are emerging as the renewable energy industry has seen dramatic change in recent years in Alberta, with costs dropping and an array of wind and solar developments moving ahead, even as solar expansion faces challenges in the province.

The former NDP government had an aggressive target to see green energy sources make up 30 per cent of all electricity generation by 2030.

Last week, the Alberta Electric System Operator put out its long-term outlook, with its base-case scenario projecting moderate demand growth for power over the next two decades. However, the expected load growth — expanding by an average of 0.9 per cent annually until 2039 — is only half the rate seen in the past 20 years.

Natural gas will become the main generation source in the province as coal-fired power (now comprising more than one-third of generation) is phased out.

Renewable projects initiated under the former NDP government’s REP program will come online in the near term, while “additional unsubsidized renewable generation is expected to develop through competitive market mechanisms and support from corporate power purchase agreements,” the report states.

AESO forecasts installed generation capacity for renewables will almost double to about 19 per cent by 2030, with wind and solar increasing to 21 per cent by 2039.

Another key policy issue for the sector will likely come within the next few weeks when the provincial government introduces details of its new Technology Innovation and Emissions Reduction program (TIER).

The initiative will require large industrial emitters to reduce greenhouse gas emissions to a benchmark level, pay into the technology fund, or buy offsets or credits. The carbon price is expected to be around $20 to $30 a tonne, and the system will kick in on Jan. 1, 2020.

Industry players point out the decision to stick with Alberta’s energy-only market along with the details surrounding TIER, and a focus by government on reducing red tape, should all help the sector attract investment.

“It is pretty clear there is a path forward for renewables here in the province,” said Evan Wilson, regional director with the Canadian Wind Energy Association.

All of these factors are propelling the wind and solar sector forward in the province, at the same time the oil and gas sector faces challenges to grow.

But it doesn’t have to be an either/or choice for the province moving forward. We’re going to need many forms of energy in the coming decades, and Alberta is an energy powerhouse, with potential to develop more wind and solar, as well as oil and natural gas resources.

“What we see sometimes is the politics and discussion around renewables or oil becomes a deliberate attempt to polarize people,” Arnold added.

“What we are trying to show, in working in Alberta on renewable projects, is it doesn’t have to be polarizing. There are a lot of solutions.

“The combination of solutions is part of what we need to talk about.”

Taiwan's economic minister resigns over widespread power outage

Taiwan Power Blackout disrupts Taipei and commercial hubs after a Taoyuan natural gas plant error, triggering nationwide outage, grid failure, elevator rescues, power rationing, and the economic minister's resignation, as CPC Corporation restores supply.

 

Key Points

A nationwide Taiwan outage from human error at a Taoyuan gas plant, triggering rationing and a minister's resignation.

✅ Human error disrupted natural gas supply at Taoyuan plant

✅ 6.68 million users affected; grid failure across cities

✅ Minister Lee resigned; President Tsai ordered a review

 

Taiwan's economic minister resigned after power was knocked out in many parts of Taiwan, with regional parallels such as China power cuts highlighting grid vulnerabilities, including capital Taipei's business and high-end shopping district, due to an apparent "human error" at a key power plant.

Economic Affairs minister Lee Chih-kung tendered his resignation verbally to Premier Lin Chuan, United Daily News reported, citing a Cabinet spokesman. Lin accepted the resignation, the spokesman said according to the daily.

As many as 6.68 million households and commercial units saw their power supply cut or disrupted on Tuesday after "human error" disrupted natural gas supply at a power plant in northern Taiwan's Taoyuan, the semi-official Central News Agency reported, citing the government-controlled oil company CPC Corporation as saying.

The company added that power at the plant, Taiwan's biggest natural gas power plant, resumed two minutes later.

In New Taipei City, there were at least 27,000 reported cases of people being stuck in lifts. Photos in social media also showed huge crowds stranded in lift lobby in Taipei's iconic 101-storey Taipei 101 building.

Power rationing was implemented beginning 6pm, and, as seen in the National Grid short supply warning in other markets, such steps aim to stabilize supply, Central News Agency said. Power supply was gradually being restored beginning at about 9:40pm. news reports said.

President Tsai Ing-wen apologised for the blackout, noting parallels with Japan's near-blackouts that underscored grid resilience, and said that she has ordered all relevant departments to produce clear report in the shortest time possible.

"Electricity is not just a problem about people's livelihoods but also a national security issue. A comprehensive review must be carried out to find out how the electric power system can be so easily paralysed by human error," said Ms Tsai in a Facebook post.

Taiwan has been at risk of a power shortage after a recent typhoon knocked down a power transmission tower in Hualien county along the eastern coast of Taiwan, rather than a demand-driven slowdown like the China power demand drop during pandemic factory shutdowns. This reduced the electricity supply by 1.3million kilowatts, or about 4 per cent of the operating reserve.

That was followed by the breakdown of a power generator at Taiwan's largest power plant, which further reduced the operating reserve by 1.5 per cent.

The situation is worsened by the ongoing heatwave that has hit Taiwan, with temperatures soaring to 38 degrees Celsius over the past week.

As a result, the government had imposed the rationing of electricity, and, highlighting how regional strains such as China's power woes can ripple into global markets, switched off all air-conditioning in many of its Taipei offices, a move that drew some public backlash.

Electricity bills on the rise in Calgary after

Calgary Electricity Price Increase signals higher ENMAX bills as grid demand surges; wholesale market volatility, fixed vs floating rates, kWh costs, and transmission charges drive above-average pricing across Alberta this winter.

 

Key Points

A market-led rise in Calgary power rates as grid demand and wholesale volatility affect fixed and floating plans.

✅ ENMAX warns of higher winter prices amid record grid demand

✅ Fixed rates hedge wholesale volatility; floating tracks spot market

✅ Transmission and distribution fees rise 5-10 percent annually

 

Calgarians should expect to be charged more for their electricity bills amid significant demand on the grid and a transition to above-average rates across Alberta.

ENMAX, one of the most-used electricity providers in the city, has sent an email to customers notifying them of higher prices for the rest of the winter months.

“Although fluctuations in electricity market prices are normal, we have seen a general trend of increasing rates over time,” the email to customers read.

“The price volatility we are forecasting is due to market factors beyond a single energy provider, including but not limited to expectations for a colder-than-normal winter and changes in electricity supply and demand in Alberta’s wholesale market. ”

Earlier this month, the province set a record for electricity usage during a bitterly cold stretch of weather.

According to energy comparison website energyrates.ca, Alberta’s energy prices have increased by 34 per cent between November 2020 and 2021.

“One of the reasons that this increase seems so significant is we’re actually coming off of a low period in the market,” the site’s founder Joel MacDonald told Global News. “You’re seeing rates well below average transitioning to well above average.”

According to ENMAX’s rate in January, the price of electricity currently sits at 15.9 cents per kilowatt-hour, with an electricity price spike from 7.9 cents per kilowatt-hour last year.

MacDonald said prices for electricity have been relatively low since 2018 but a swing in the price of oil has created more activity in the province’s industrial sector, and in turn more demand on the power grid.

According to MacDonald, the price increase can also be attributed to the removal of a consumer price cap that limited regulated rates to 6.8 cents per kilowatt-hour for households and small businesses with lower demand, which, after the carbon tax was repealed, initially remained in place.

Although the cap was scrapped by the UCP three years ago, he said energy bills now depend on the rate set by the market.

“What’s increased now recently is actually the price per kilowatt, and the (transmission and distribution) charges have only increased, but annually they increase between five and 10 per cent,” MacDonald said. “So the portion of your bill that’s increasing is different than what Albertans are typically used to, or at least in recent memory.”

But Albertans do have options, MacDonald said.

As part of its email to customers, ENMAX sent a list of energy saving tips to reduce energy consumption in people’s homes, including using cold water for laundry and avoiding dryer use, energy-efficient lightbulbs and unplugging electronics when they are not in use.

Retailers also offer contracts with floating or fixed rates for consumers.

“Fixed rates, obviously, you’re going to pick your price. It’s going to be the same each and every single month,” MacDonald said. “Floating rate is based off the wholesale spot market, and that has been exceptionally high the last few months.”

He said consumers looking to save money when electricity prices are high should look into a fixed rate.

Kenya on Course for $5 Billion Nuclear Plant to Power Industry

Kenya Nuclear Power Plant Project advances with environmental impact assessment, selecting Tana River County under a build-operate-transfer model to boost grid capacity, support manufacturing growth, and assess reactor technology for reliable baseload energy.

 

Key Points

A $5B BOT nuclear facility in Tana River to expand Kenya's grid, aiming to start operations in about seven years.

✅ Environmental impact study published for public review by NEMA

✅ Preferred site: Tana River County near coast; grid integration

✅ BOT concession; reactor tech under evaluation for baseload

 

Kenya’s nuclear agency submitted impact studies for a $5 billion power plant, and said it’s on course to build and start operating the facility in about seven years, as markets like China's nuclear program continue steady expansion.

The government plans to expand its nuclear-power capacity fourfold by 2035, mirroring policy steps in India to revive the sector, the Nuclear Power and Energy Agency said in a report on the National Environment Management Authority’s website. The document is set for public scrutiny before the environmental watchdog can approve it, aligning with global green industrial strategies that weigh nuclear in decarbonization, and pave the way for the project to continue.

President Uhuru Kenyatta wants to ramp up installed generation capacity from 2,712 megawatts as of April to boost manufacturing in East Africa’s largest economy, noting milestones such as Barakah Unit 1 reaching 100% power as indicators of nuclear readiness. Kenya expects peak demand to top 22,000 megawatts by 2031, and other jurisdictions, such as Ontario's exploration of new nuclear, are weighing similar large-scale options, partly due to industrial expansion, a component in Kenyatta’s Big Four Agenda. The other three are improving farming, health care and housing.

The nuclear agency is assessing technologies “to identify the ideal reactor for the country,” it said in the report, including next-gen nuclear designs now being evaluated.

A site in Tana River County, near the Kenyan coast was preferred after studies across three regions, according to the report. The plant will be developed with a concessionaire under a build, operate and transfer model, with innovators such as mini-reactor concepts informing vendor options.

Failed PG&E power line blamed for Drum fire off Hwy 246 last June

PG&E Drum Fire Cause identified as a power line failure in Santa Barbara County, with arcing electricity igniting vegetation near Buellton on Drum Canyon Road; 696 acres burned as investigators and CPUC review PG&E safety.

 

Key Points

A failed PG&E power line sparked the 696-acre Drum Fire near Buellton; the utility is conducting its own probe.

✅ Power line failed between poles, arcing ignited vegetation.

✅ 696 acres burned; no structures damaged or injuries.

✅ PG&E filed CPUC incident report; ongoing investigation.

 

A downed Pacific Gas and Electric Co. power line was the cause of the Drum fire that broke out June 14 on Drum Canyon Road northwest of Buellton, a reminder that a transformer explosion can also spark multiple fires, the Santa Barbara County Fire Department announced Thursday.

The fire broke out about 12:50 p.m. north of Highway 246 and burned about 696 acres of wildland before firefighters brought it under control, although no structures were damaged or mass outages like the Los Angeles power outage occurred, according to an incident summary.

A team of investigators pinpointed the official cause as a power line that failed between two utility poles and fell to the ground, and as downed line safety tips emphasize, arcing electricity ignited the surrounding vegetation, said County Fire Department spokesman Capt. Daniel Bertucelli.

In response, a PG&E spokesman said the utility is conducting its own investigation and does not have access to whatever data investigators used, and, as the ATCO regulatory penalty illustrates, such matters can draw significant oversight, but he noted the company filed an electric incident report on the wire with the California Public Utilities Commission on June 14.

"We are grateful to the first responders who fought the 2020 Drum fire in Santa Barbara County and helped make sure that there were no injuries or fatalities, outcomes not always seen in copper theft incidents, and no reports of structures damaged or burned," PG&E spokesman Mark Mesesan said.

"While we are continuing to conduct our own investigation into the events that led to the Drum fire, and as the Site C watchdog inquiry shows, oversight bodies can seek more transparency, PG&E does not have access to the Santa Barbara County Fire Department's report."

He said PG&E remains focused on reducing wildfire risk across its service area while limiting the scope and duration of public safety power shutoffs, including strategies like line-burying decisions adopted by other utilities, and that the safety of customers and communities it serves are its most important responsibility.

TotalEnergies Africa Energy Strategy 2025 spotlights oil, gas, LNG, and renewables, with investments in Namibia, Congo, Mozambique, Uganda, Morocco, and South Africa, driving upstream growth, clean energy, and energy transition partnerships.

 

Key Points

An investment roadmap uniting oil, gas, LNG, and renewables to speed Africa's upstream growth and energy transition.

✅ Keynote by Mike Sangster at IAE Paris 2025.

✅ Oil, gas, LNG projects across Namibia, Congo, Mozambique, Uganda.

✅ Scaling renewables: solar, wind, green ammonia for export.

 

Mike Sangster, Senior Vice President for Africa at TotalEnergies, will play a pivotal role in the upcoming Invest in African Energy (IAE) Forum, which will take place in Paris on May 13-14, 2025. As a key figure in one of the world’s largest energy companies, Sangster's participation in the forum is expected to offer crucial insights into Africa’s evolving energy landscape, particularly in the areas of oil, gas, and renewable energy.

TotalEnergies' Role in Africa's Energy Landscape

TotalEnergies has long been a major player in Africa’s energy sector, driving development across both emerging and established markets. The company has a significant footprint in countries such as Namibia, the Republic of Congo, Libya, Mozambique, Uganda, and South Africa. TotalEnergies’ investments span both traditional oil and gas projects as well as renewable energy initiatives, reflecting its commitment to a more diversified energy future for Africa.

In Namibia, for instance, TotalEnergies is advancing its Venus-1 discovery, with plans to produce its first oil by the end of the decade. The company is also heavily involved in the Orange Basin exploration. Meanwhile, in the Republic of Congo, TotalEnergies is investing $600 million to enhance deepwater production at its Moho Nord field.

Beyond oil and gas, the company is expanding its renewable energy portfolio across the continent. This includes significant solar, wind, and hydropower projects, such as the 500 MW Sadada solar project in Libya, a 216 MW solar plant with battery storage in South Africa, and a 1 GW wind and solar project in Morocco designed to produce green ammonia for export.

The Invest in African Energy Forum

The IAE Forum, which TotalEnergies’ Sangster will headline, is an exclusive event aimed at facilitating investment between African energy markets and global investors, including discussions on COVID-19 funding for electricity access mechanisms that emerged, and their relevance to current capital flows. With a focus on fostering partnerships and discussions about the future of energy in Africa, the event will bring together industry experts, project developers, investors, and policymakers for two days of intensive engagement.

The forum will also serve as a crucial platform for sharing perspectives on the role of private investment, as outlined in the IEA investment outlook for Africa's power systems, in Africa’s energy future, strategies for unlocking new upstream opportunities, and the transition to a more sustainable energy system. This makes Sangster's participation, as someone directly involved in both conventional and renewable energy projects across the continent, particularly significant.

TotalEnergies' Diversified Strategy in Africa

Sangster’s keynote address and participation in an exclusive fireside chat will provide an in-depth look into TotalEnergies’ strategy for Africa. His insights will touch upon the company's ongoing projects in the oil and gas sectors, as well as its renewable energy investments. TotalEnergies has committed to making its portfolio more sustainable, underscored by its recent VSB acquisition to expand renewables capabilities, while continuing to be a leader in the energy transition.

One of the company’s notable projects is the Mozambique LNG initiative, a $20 billion venture aimed at supplying liquefied natural gas to international markets. Additionally, TotalEnergies is gearing up for the first oil from its Tilenga field in Uganda, which will be transported through the East African Crude Oil Pipeline (EACOP), the longest heated crude oil pipeline in the world.

In South Africa, TotalEnergies is constructing one of the largest renewable energy projects, a 216 MW solar power plant with integrated battery storage. This project is expected to significantly contribute to the country’s clean energy ambitions. Furthermore, in Morocco, TotalEnergies is developing a major wind and solar facility that will produce green ammonia, aligning with its broader strategy to provide solutions for Europe’s energy needs.

Africa’s Energy Transition

The forum’s timing could not be more critical, given the pressing need for an energy transition in Africa. While the continent remains heavily reliant on fossil fuels for its energy needs, there is growing momentum toward incorporating renewable energy sources, a point reinforced by the IRENA renewables report on decarbonisation and quality of life, which highlights the transformative potential. Africa’s vast natural resources, combined with global investments and partnerships, position the continent as a key player in the global shift toward sustainable energy.

However, Africa faces unique challenges in transitioning to renewable energy, reflecting a broader Sub-Saharan electricity challenge that also presents opportunity, across many markets. These challenges include a lack of infrastructure, financial constraints, and the need for increased political stability in certain regions. The IAE Forum provides an opportunity to address these barriers, with industry leaders like Sangster offering solutions based on real-world experiences and investments.

As the energy sector continues to evolve globally, and even if electricity systems are unlikely to go fully green this decade according to some outlooks, Africa's potential remains vast. The continent’s diverse energy resources, from oil and gas to renewables, offer a unique opportunity to build a more sustainable and resilient energy future. The Invest in African Energy Forum serves as an important platform for global stakeholders to collaborate, learn, and invest in the energy transformation taking place across the continent.

Mike Sangster’s insights at the forum will undoubtedly shape discussions on how companies like TotalEnergies are navigating the intersection of universal electricity access goals, sustainability, and economic growth in Africa. With Africa’s energy needs expected to increase exponentially in the coming decades, ensuring that these needs are met sustainably and equitably will be a priority for both policymakers and private investors.

As the global energy landscape continues to shift, the Invest in African Energy Forum provides a critical space for shaping the future of Africa’s energy sector, offering invaluable opportunities for investment, innovation, and collaboration.
