BC Hydro still in dark about cause of blackout

Surkhan-Pul-e-Khumri Power Line links Uzbekistan and Afghanistan via a 260-kilometer transmission line, boosting electricity exports, grid reliability, and regional trade; ADB-backed financing could open Pakistan's energy market with 24 million kWh daily.

Key Points

A 260-km line to expand Uzbekistan power exports to Afghanistan, ADB-funded, with possible future links to Pakistan.

✅ 260 km Surkhan-Pul-e-Khumri transmission link

✅ +70% electricity exports; up to 24M kWh daily

✅ ADB $70M co-financing; $32M from Uzbekistan

Senior officials with Uzbekistan’s state-run power company have said work has begun on building power cables to Afghanistan that will enable them to increase exports by 70 per cent, echoing regional trends like Ukraine resuming electricity exports after grid repairs.

Uzbekenergo chief executive Ulugbek Mustafayev said in a press conference on March 24 that construction of the Afghan section of the 260-kilometer Surkhan-Pul-e-Khumri line will start in June.

The Asian Development Bank has pledged $70 million toward the final expected $150 million bill of the project. Another $32 million will come from Uzbekistan.

Mustafayev said the transmission line would give Uzbekistan the option of exporting up to 24 million kilowatt hours to Afghanistan daily, similar to Ukraine's electricity export resumption amid shifting regional demand.

“We could potentially even reach Pakistan’s energy market,” he said, noting broader regional ambitions like Iran's bid to be a power hub linking regional grids.

This project was given fresh impetus by Afghan President Ashraf Ghani’s visit to Tashkent in December, mirroring cross-border energy cooperation such as Iran-Iraq energy talks in the region. His Uzbek counterpart, Shavkat Mirziyoyev, had announced at the time that work was set to begin imminently on the line, which will run from the village of Surkhan in Uzbekistan’s Surkhandarya region to Pul-e-Khumri, a town in Afghanistan just south of Kunduz.

In January, Mirziyoyev issued a decree ordering that the rate for electricity deliveries to Afghanistan be dropped from $0.076 to $0.05 per kilowatt.

Mustafayev said up to 6 billion kilowatt hours of electricity could eventually be sent through the power lines. More than 60 billion kilowatt hours of electricity was produced in Uzbekistan in 2017.

According to Tulabai Kurbonov, an Uzbek journalist specializing in energy issues, the power line will enable the electrification of the the Hairatan-Mazar-i-Sharif railroad joining the two countries. Trains currently run on diesel. Switching over to electricity will help reduce the cost of transporting cargo.

There is some unhappiness, however, over the fact that Uzbekistan plans to sell power to Afghanistan when it suffers from significant shortages domestically and wider Central Asia electricity shortages persist.

"In the villages of the Ferghana Valley, especially in winter, people are suffering from a shortage of electricity,” said Munavvar Ibragimova, a reporter based in the Ferghana Valley. “You should not be selling electricity abroad before you can provide for your own population. What we clearly see here is the favoring of the state’s interests over those of the people.”

Ireland 65% Renewable Grid Capability showcases world leading integration of intermittent wind and solar, smart grid flexibility, EU-SysFlex learnings, and the Celtic Interconnector to enhance stability, exports, and energy security across the European grid.

Key Points

Ireland can run its isolated power system with 65% variable wind and solar, informing EU grid integration and scaling.

✅ 65% system non-synchronous penetration on an isolated grid

✅ EU-SysFlex roadmap supports large-scale renewables integration

✅ Celtic Interconnector adds 700MW capacity and stability

Ireland is now able to cope with 65% of its electricity coming from intermittent electricity sources like wind and solar, as highlighted by Ireland's green electricity outlook today – an expertise Energy Minister Denish Naugthen believes can be replicated on a larger scale as Europe moves towards 50% renewable power by 2030.

Denis Naughten is an Irish politician who serves as Minister for Communications, Climate Action and Environment since May 2016.

Naughten spoke to editor Frédéric Simon on the sidelines of a EURACTIV event in the European  Parliament to mark the launch of EU-SysFlex, an EU-funded project, which aims to create a long-term roadmap for the large-scale integration of renewable energy on electricity grids.

What is the reason for your presence in Brussels today and the main message that you came to deliver?

The reason that I’m here today is that we’re going to share the knowledge what we have developed in Ireland, right across Europe. We are now the global leaders in taking variable renewable electricity like wind and solar onto our grid.

We can take a 65% loading on to the grid today – there is no other isolated grid in the world that can do that. We’re going to get up to 75% by 2020. This is a huge technical challenge for any electricity grid and it’s going to be a problem that is going to grow and grow across Europe, even as Europe's electricity demand rises in the coming years, as we move to 50% renewables onto our grid by 2030.

And our knowledge and understanding can be used to help solve the problems right across Europe. And the sharing of technology can mean that we can make our own grid in Ireland far more robust.

What is the contribution of Ireland when it comes to the debate which is currently taking place in Europe about raising the ambition on renewable energy and make the grid fit for that? What are the main milestones that you see looking ahead for Europe and Ireland?

It is a challenge for Europe to do this, but we’ve done it Ireland. We have been able to take a 65% loading of wind power on our grid, with Irish wind generation hitting records recently, so we can replicate that across Europe.

Yes it is about a much larger scale and yes, we need to work collaboratively together, reflecting common goals for electricity networks worldwide – not just in dealing with the technical solutions that we have in Ireland at the fore of this technology, but also replicating them on a larger scale across Europe.

And I believe we can do that, I believe we can use the learnings that we have developed in Ireland and amplify those to deal with far bigger challenges that we have on the European electricity grid.

Trialogue talks have started at European level about the reform of the electricity market. There is talk about decentralised energy generation coming from small-scale producers. Do you see support from all the member states in doing that? And how do you see the challenges ahead on a political level to get everyone on board on such a vision?

I don’t believe there is a political problem here in relation to this. I think there is unanimity across Europe that we need to support consumers in producing electricity for self-consumption and to be able to either store or put that back into the grid.

The issues here are more technical in nature. And how you support a grid to do that. And who actually pays for that. Ireland is very much a microcosm of the pan-European grid and how we can deal with those challenges.

What we’re doing at the moment in Ireland is looking at a pilot scheme to support consumers to generate their own electricity to meet their own needs and to be able to store that on site.

I think in the years to come a lot of that will be actually done with more battery storage in the form of electric vehicles and people would be able to transport that energy from one location to another as and when it’s needed. In the short term, we’re looking at some novel solutions to support consumers producing their own electricity and meeting their own needs.

So I think this is complex from a technical point of view at the moment, I don’t think there is an unwillingness from a political perspective to do it, and I think working with this particular initiative and other initiatives across Europe, we can crack those technical challenges.

To conclude, last year, the European Commission allocated €4 million to a project to link up the Irish electricity grid to France. How is that going to benefit Ireland? And is that related to worries that you may have over Brexit?

The plan, which is called the Celtic Interconnector, is to link France with the Irish electricity grid. It’s going to have a capacity of about 700MW. It allows us to provide additional stability on our grid and enables us to take more renewables onto the grid. It also allows us to export renewable electricity onto the main European grid as well, and provide stability to the French network.

So it’s a benefit to both individual networks as well as allowing far more renewables onto the grid. We’ve been working quite closely with RTE in France and with both regulators. We’re hoping to get the support of the European Commission to move it now from the design stage onto the construction stage. And I understand discussions are ongoing with the Commission at present with regard to that.

And that is going to diversify potential sources of electricity coming in for Ireland in a situation which is pretty uncertain because of Brexit, correct?

Well, I don’t think there is uncertainty because of Brexit in that we have agreements with the United Kingdom, we’re still going to be part of the broader energy family in relation to back-and-forth supply across the Irish Sea, with grid reinforcements in Scotland underscoring reliability needs.  But I think it is important in terms of meeting the 15% interconnectivity that the EU has set in relation to electricity.

And also in relation of providing us with an alternative support in relation to electricity supply outside of Britain. Because Britain is now leaving the European Union and I think this is important from a political point of view, and from a broader energy security point of view. But we don’t see it in the short term as causing threats in relation to security of supply.

Manitoba Hydro Debt Load surges past $19.2B as the Crown corporation faces shrinking net income, restructuring costs, and PUB rate decisions, driven by Bipole III, Keeyask construction, aging infrastructure, and rising interest rate risks.

Key Points

Manitoba Hydro Debt Load refers to the utility's escalating borrowings exceeding $19B, pressuring rates and finances.

✅ Debt rose to $19.2B; projected near $25B within five years.

✅ Major drivers: Bipole III, Keeyask, aging assets, restructuring.

✅ Rate hikes sought; PUB approved 3.6% vs 7.9% request.

Manitoba Hydro's debt load now exceeds $19 billion as the provincial Crown corporation grapples with a shrinking net income amid ongoing efforts to slay costs.

The utility's annual report, to be released publicly on Tuesday, also shows its total consolidated net income slumped from $71 million in 2016-2017 to $37 million in the last fiscal year, mirroring a Hydro One profit drop as electricity revenue fell.

It said efforts to restructure the utility and reduce costs are partly to blame for the $34 million drop in year-over-year income.

These earnings come nowhere close, however, to alleviating Hydro's long-term debt problem, a dynamic also seen in a BC Hydro deferred costs report about customer exposure. The figure is pegged at $19.2 billion this fiscal year, up from $16.1 billion the previous year and $14.2 billion in 2016.

The utility projects its debt will grow to about $25 billion in the next five years. Its largest expenses include finishing the Bipole III line, working on the Keeyask Generating System that is halfway done and rebuilding aging wood poles and substations, the report said.

"This level of debt increases the potential financial exposure from risks facing the corporation and is a concern for both

the corporation and our customers who may be exposed to higher rate increases in the event of rising interest rates, a prolonged drought or a major system failure," outgoing president and CEO Kelvin Shepherd wrote.

The income drop is primarily a result of the $50 million spent in the form of restructuring charges associated with the utility's efforts to streamline the organization and drive down costs, amid NDP criticism of Hydro changes related to government policy.

Those efforts included the implementation of buyouts for employees through what the utility dubbed its "voluntary departure program."

Among the changes, Manitoba Hydro reduced its workforce by 800 employees, which is expected to save the utility over $90 million per year. It also reduced its management positions by 26 per cent, a Monday news release said, while Hydro One leadership upheaval in Ontario drove its shares down during comparable governance turmoil.

To improve its financial situation, Hydro has applied for rate increases, even as the Consumers Coalition pushes to have the proposal rejected. The Public Utilities Board offered a 3.6 per cent average rate hike, instead of the 7.9 per cent jump the utility asked for.

In May, when the PUB rendered its decision, it made several recommendations as an alternative to raising rates, including receiving a share of carbon tax revenue and asking the government to help pay for Bipole III.

Hydro is projecting a net income of $70 million for 2018-2019, which includes the impact of the recent rate increase. That total reflects an approximately 20 per cent reduction in net income from 2017-18 after restructuring costs are calculated.

Air Humidity Energy Harvesting converts thin air into clean electricity using air-gen devices with nanopores, delivering continuous renewable energy from ambient moisture, as demonstrated by UMass Amherst researchers in Advanced Materials.

Key Points

A method using nanoporous air-gen devices to harvest continuous clean electricity from ambient atmospheric moisture.

✅ Nanopores drive charge separation from ambient water molecules

✅ Works across materials: silicon, wood, bacterial films

✅ Predictable, continuous power unlike intermittent solar or wind

Sure, we all complain about the humidity on a sweltering summer day. But it turns out that same humidity could be a source of clean, pollution-free energy, aligning with efforts toward cheap, abundant electricity worldwide, a new study shows.

"Air humidity is a vast, sustainable reservoir of energy that, unlike wind and solar power resources, is continuously available," said the study, which was published recently in the journal Advanced Materials.

While humidity harvesting promises constant output, advances like a new fuel cell could help fix renewable energy storage challenges, researchers suggest.

“This is very exciting,” said Xiaomeng Liu, a graduate student at the University of Massachusetts-Amherst, and the paper’s lead author. “We are opening up a wide door for harvesting clean electricity from thin air.”

In fact, researchers say, nearly any material can be turned into a device that continuously harvests electricity from humidity in the air, a concept echoed by raindrop electricity demonstrations in other contexts.

“The air contains an enormous amount of electricity,” said Jun Yao, assistant professor of electrical and computer engineering at the University of Massachusetts-Amherst and the paper’s senior author. “Think of a cloud, which is nothing more than a mass of water droplets. Each of those droplets contains a charge, and when conditions are right, the cloud can produce a lightning bolt – but we don’t know how to reliably capture electricity from lightning.

"What we’ve done is to create a human-built, small-scale cloud that produces electricity for us predictably and continuously so that we can harvest it.”

The heart of the human-made cloud depends on what Yao and his colleagues refer to as an air-powered generator, or the "air-gen" effect, which relates to other atmospheric power concepts like night-sky electricity studies in the field.

In broader renewable systems, flexible resources such as West African hydropower can support variable wind and solar output, complementing atmospheric harvesting concepts as they mature.

The study builds on research from a study published in 2020. That year, scientists said this new technology "could have significant implications for the future of renewable energy, climate change and in the future of medicine." That study indicated that energy was able to be pulled from humidity by material that came from bacteria; related bio-inspired fuel cell design research explores better electricity generation, the new study finds that almost any material, such as silicon or wood, also could be used.

The device mentioned in the study is the size of a fingernail and thinner than a single hair. It is dotted with tiny holes known as nanopores, it was reported. "The holes have a diameter smaller than 100 nanometers, or less than a thousandth of the width of a strand of human hair."

Puerto Rico Tesla Solar Power enables resilient microgrids using batteries, renewable energy, and energy storage to rebuild the hurricane-damaged grid, reduce fossil fuels, cut costs, and accelerate recovery with scalable solar-plus-storage solutions.

Key Points

A solar-plus-storage plan using Tesla microgrids and batteries to restore Puerto Rico's cleaner, resilient power.

✅ Microgrids cut diesel reliance and harden critical facilities.

✅ Batteries stabilize the grid and shave peak demand costs.

✅ Scalable solar enables faster, modular disaster recovery.

Puerto Rico’s governor Ricardo Rossello has said that he will speak to Elon Musk after the Tesla inventor said his innovative solar and battery systems could be used to restore electricity on the island.

Mr Musk was mentioned in a tweet, referencing an article discussing ways to restore Puerto Rico’s power grid, which was knocked out by Hurricane Maria on September 20.

Restoring the ageing and already-weakened network has proved slow: as of Friday 90 per cent of the island remained without power. The island’s electricity company was declared bankrupt in July.

Mr Musk was asked: “Could @ElonMusk go in and rebuild #PuertoRico’s electricity system with independent solar & battery systems?”

The South African entrepreneur replied: “The Tesla team has done this for many smaller islands around the world, but there is no scalability limit, so it can be done for Puerto Rico too.

“Such a decision would be in the hands of the PR govt, PUC, any commercial stakeholders and, most importantly, the people of PR.”

His suggestion was seized upon by Mr Rossello, who then tweeted: “@ElonMusk Let's talk. Do you want to show the world the power and scalability of your #TeslaTechnologies?

“PR could be that flagship project.”

Mr Musk replied that he was happy to talk.

Restoring power to the battered island is a priority for the government, and improving grid resilience remains critical, with hospitals still running on generators and the 3.5 million people struggling with a lack of refrigeration or air conditioning.

Radios broadcast messages advising people how to keep their insulin cool, and doctors are concerned about people not being able to access dialysis.

And, with its power grid wiped out, the Caribbean island could totally rethink the way it meets its energy needs, drawing on examples like a resilient school microgrid built locally. 

“This is an opportunity to completely transform the way electricity is generated in Puerto Rico and the federal government should support this,” said Judith Enck, the former administrator for the region with the environmental protection agency.

“They need a clean energy renewables plan and not spending hurricane money propping up the old fossil fuel infrastructure.”

Forty-seven per cent of Puerto Rico’s power needs were met by burning oil last year - a very expensive and outdated method of electricity generation. For the US as a whole, petroleum accounted for just 0.3 per cent of all electricity generated in 2016 even as the grid isn’t yet running on 100% renewable energy nationwide.

The majority of the rest of Puerto Rico’s energy came courtesy of coal and natural gas, with renewables, which later faced pandemic-related setbacks, accounting for only two per cent of electricity generation.

“In that time of extreme petroleum prices, the utility was borrowing money and buying oil in order to keep those plants operating,” said Luis Martinez, a lawyer at natural resources defense council and former special aide to the president of Puerto Rico’s environmental quality board.

“That precipitated the bankruptcy that followed. It was in pretty poor shape before the storm. Once the storm got there, it finished the job.”

But Mr Martinez told the website Earther that it might be difficult to secure the financing for rebuilding Puerto Rico with renewables from FEMA (Federal Emergency Management Agency) funds.

“A lot of distribution lines were on wood poles,” he said.

“Concrete would make them more resistant to winds, but that would potentially not be authorized under the use of FEMA funds.

"We’re looking into if some of those requirements can be waived so rebuilding can be more resilient.”

Global Renewable Electricity Milestone signals solar, wind, hydro, and geothermal surpass 30% of power generation, driven by falling costs, battery storage, smart grids, and ambitious policy targets that strengthen energy security and decarbonization.

Key Points

It marks renewables exceeding 30% of global power, enabled by cheaper tech, storage, and strong policy.

✅ Costs of solar and wind fall, boosting competitiveness

✅ Storage and smart grids improve reliability and flexibility

✅ Policies target decarbonization while ensuring just transition

A recent report by the energy think tank Ember marks a significant milestone in the global energy transition. For the first time ever, according to their analysis, renewable energy sources like solar, wind, hydro, and geothermal now account for more than 30% of the world's electricity generation, a milestone echoed by wind and solar growth globally. This achievement signifies a pivotal shift towards a cleaner and more sustainable energy future.

The report attributes this growth to several key factors. Firstly, the cost of renewable energy technologies like solar panels and wind turbines has plummeted in recent years, making them increasingly competitive with traditional fossil fuels. Secondly, advancements in battery storage technology are facilitating the integration of variable renewable sources like solar and wind into the grid, addressing concerns about reliability. Thirdly, a growing number of countries are implementing ambitious renewable energy targets and policies, driven by environmental concerns and the desire for energy security.

The rise of renewables is not uniform across the globe. Europe leads the pack, with the European Union generating a staggering 44% of its electricity from renewable sources in 2023. Countries like Denmark, Germany, and Spain are at the forefront of this clean energy revolution. Developing nations are also starting to embrace renewables, driven by factors like falling technology costs and the need for affordable electricity access.

However, challenges remain. Fossil fuels still dominate the global energy mix, accounting for roughly two-thirds of electricity generation. Integrating a higher proportion of variable renewables into the grid necessitates robust storage solutions and smart grid technologies. Additionally, the transition away from fossil fuels needs to be managed carefully to ensure a just and equitable outcome for workers in the coal, oil, and gas sectors.

Despite these challenges, the report by Ember paints an optimistic picture. The rapid growth of renewables demonstrates their increasing viability and underscores the global commitment to a cleaner energy future, and in the United States, for example, renewables are projected to reach one-fourth of U.S. electricity generation, reinforcing this trajectory. The report also highlights the economic benefits of renewables, with new jobs created in the clean energy sector and reduced reliance on volatile fossil fuel prices.

Looking ahead, continued technological advancements, supportive government policies, and increased investment in renewable energy infrastructure are all crucial for further growth, with scenarios such as BNEF's 2050 outlook suggesting wind and solar could provide half of electricity, underscoring the importance of sustained effort. Furthermore, international cooperation is essential to ensure a smooth and equitable global energy transition. Developed nations can play a vital role by sharing technology and expertise with developing countries.

The 30% milestone is a significant step forward, but it's just the beginning. As the world strives to combat climate change and ensure energy security for future generations, renewables are poised to play a central role in powering a sustainable future, with wind and solar surpassing coal in the U.S. offering a clear signal of the shift. The report by Ember serves as a powerful reminder that a clean energy future is not just a dream, but a rapidly unfolding reality.
