Wind Denmark - summer's autumn weather provides extraordinarily low electricity prices

SDG&E Ramona Microgrid delivers renewable energy and battery storage for wildfire mitigation, grid resilience, and PSPS support, powering the Cal Fire Air Attack Base with a 500 kW, 2,000 kWh lithium-ion system during outages.

Key Points

A renewable, battery-backed microgrid powering Ramona's Air Attack Base, boosting wildfire response and PSPS resilience.

✅ 500 kW, 2,000 kWh lithium-ion storage replaces diesel

✅ Keeps Cal Fire and USFS aircraft operations powered

✅ Supports PSPS continuity and rural water reliability

It figures to be another dry year — with the potential to spark wildfires in the region. But San Diego Gas & Electric just completed a renewable energy upgrade to a microgrid in Ramona that will help firefighters and reduce the effects of power shutoffs to backcountry residents.

The microgrid will provide backup power to the Ramona Air Attack Base, helping keep the lights on during outages, home to Cal Fire and the U.S. Forest Service's fleet of aircrafts that can quickly douse fires before they get out of hand.

"It gives us peace of mind to have backup power for a critical facility like the Ramona Air Attack Base, especially given the fact that fire season in California has become year-round," Cal Fire/San Diego County Fire Chief Tony Mecham said in a statement.

The air attack base serves as a hub for fixed-wing aircraft assigned to put out fires. Cal Fire staffs the base throughout the year with one two airtankers and one tactical aircraft. The base also houses the Forest Service's Bell 205 A++ helicopter and crew to protect the Cleveland National Forest. Aircraft for both CalFire and the Forest Service can also be mobilized to help fight fires throughout the state.

This summer, the Ramona microgrid won't have to rely on diesel generation. Instead, the facility next to the town's airport will be powered by a 500 kilowatt and 2,000 kilowatt-hour lithium-ion battery storage system that won't generate any greenhouse gas emissions.

"What's great about it, besides that it's a renewable resource, is that it's a permanent installation," said Jonathan Woldemariam, SDG&E's director of wildfire mitigation and vegetation management. "In other words, we don't have to roll a portable generator out there. It's something that can be leveraged right there because it's already installed and ready to go."

Microgrids have taken on a larger profile across the state because they can operate independently of the larger electric grid, where repairing California's grid is an ongoing challenge, thus allowing small areas or communities to keep the power flowing for hours at a time during emergencies.

That can be crucial in wildfire-prone areas affected by Public Safety Power Shutoffs, or PSPS, the practice in which investor-owned utilities in California de-energize electrical power lines in a defined area when conditions are dry and windy in order to reduce the risk of a power line falling and igniting a wildfire, while power grid upgrades move forward statewide.

Rural and backcountry communities are particularly hard hit when the power is pre-emptively cut off because many homes rely on water from wells powered by electricity for their homes, horses and livestock.

In addition to Ramona, SDG&E has established microgrids in three other areas in High Fire Threat Districts:

The microgrids in Butterfield Ranch and Shelter Valley run on diesel power but the utility plans to complete solar and battery storage systems for each locale by the end of next year, as other regions develop new microgrid rules to guide deployment.

SDG&E has a fifth microgrid in operation — in Borrego Springs, which in 2013 became the first utility-scale microgrid in the country. It provides grid resiliency to the roughly 2,700 residents of the desert town and serves as a model for integrated microgrid projects elsewhere in delivering local electricity. While the Borrego Springs microgrid is not located in a High Fire Threat District, "when and if any power is turned off, especially the power transmission feed that goes to Borrego, we can support the customers using the microgrid out there," Woldemariam said.

Microgrid costs can be higher than conventional energy systems, even as projected energy storage revenue grows over the next decade, and the costs of the SDG&E projects are passed on to ratepayers. As per California Public Utilities Commission rules, the financial details for each of microgrid are kept confidential for at least three years.

SDG&E's microgrids are part of the utility's larger plan to reduce wildfire risk that SDG&E files with the utilities commission. In its wildfire plan for 2020 through 2022, SDG&E expected to spend $1.89 billion on mitigation measures.

Alberta Electricity Price Hikes spotlight grid reliability, renewable transition, coal phase-out, and energy poverty, as policy shifts and investor reports warn of rate increases, biomass trade-offs, and sustainability challenges impacting households and businesses.

Key Points

Projected power bill hikes from market reforms, renewables, coal phase-out, and reliability costs in Alberta.

✅ Investor report projects 3x-7x bills and $50B market transition costs

✅ Policy missteps cited in Ontario, Germany, Australia price spikes

✅ Debate: retain coal vs. speed renewables, storage, and grid upgrades

Since when did electricity become a scarce resource?

I thought all the talk about greening the grid was about having renewable, sustainable, less polluting options to fulfill our growing need for power. Yet, increasingly, we are faced with news stories that indicate using power is bad in and of itself, even as flat electricity demand worries utilities.

The implication, I guess, is that we should be using less of it. But, I don’t want to use less electricity. I want to be able to watch TV, turn my lights on when the sun sets at 4 p.m. in the winter, keep my food cold and power my devices.

We once had a consensus that a reliable supply of power was essential to a growing economy and a high quality of life, a point underscored by brownout risks in U.S. markets.

I’m beginning to wonder if we still have that consensus.

And more importantly, if our decision makers have determined electricity is a vice as opposed to an essential of life – as debates over Alberta electricity policy suggest – you know what is going to happen next. Prices are going to rise, forcing all of us to use less.

How much would it hurt your bottom line if your electricity bill went up three-fold? How about seven-fold? That is the grim picture that Todd Beasley painted for us on Tuesday’s show.

Last week, he launched a campaign on behalf of Albertans for Sustainable Electricity, called Stop the Shock. He shared the results of an internal investor report that concluded Alberta’s power market overhaul would cost an estimated $50 billion to implement and could result in a three to seven-fold increase in electricity bills.

Now, my typical power bill averages $70 a month. That would be like having it grow to $210 a month, or just over $2,500 a year. If it’s a seven-fold increase that would be more like $5,000 a year. That may be manageable for some families, but I can think of a lot of things I’d rather do with $5,000 than pay more to keep my fridge running so my food doesn’t spoil.

For low-income families that would be a real hardship.

Beasley said Ontario’s inept handling of its electricity market and the phase-out of coal power resulted in price spikes that left more than 70,000 individuals facing energy poverty.

Germany and Australia realized they made the same mistake and are returning some electricity to coal.

Beasley shared a long list of Canadian firms – including our own Canadian Pension Plan – that are investing in coal development around the world. Meanwhile, Canadian governments remain in a mad rush to phase it out here. That’s not the only hypocrisy.

Rupert Darwall, author of Green Tyranny: Exposing the Totalitarian Roots of the Climate Industrial Complex, revealed in a recent column what he calls “the scandal at the heart of the EU’s renewable policies.”

Turns out most of their expansion in renewable energy has come from biomass in the form of wood. Not only does burning wood produce more CO2, it also eliminates carbon sinks.

To meet the EU’s 2030 target would require cutting down trees equivalent to the combined harvest in Canada and the United States. As he puts it, “Whichever way you look at it, burning the world’s carbon sinks to meet the EU’s arbitrary renewable energy targets is environmentally insane.”

Beasley’s group is trying to bring some sanity back to the discussion. The goal should be to move to a greener grid while maintaining abundant, reliable and cheap power, and examples like Texas grid improvements show practical steps. He thinks to achieve all these goals, coal should remain part of the mix. What do you think?

Manitoba Electrification History charts arc lights, hydroelectric dams, Winnipeg utilities, transmission lines, rural electrification, and Manitoba Hydro to today's wind, solar, and EV transition across the provincial power grid, driving modernization and reliability.

Key Points

Manitoba's power evolution from arc lights to hydro and rural electrification, advancing wind and solar on a modern grid.

✅ 1873 Winnipeg arc light predates Edison and Bell.

✅ 1919 Act built transmission lines, rural electrification.

✅ Hydroelectric dams reshaped lands and affected First Nations.

The first electric light in Manitoba was turned on in Winnipeg in 1873, but it was a century ago this year that the switch was flipped on a decision that would bring power to the fingertips of people across the province.

On March 12, 1873, Robert Davis — who owned the Davis House hotel on Main Street, about a block from Portage Avenue — used an electric arc light to illuminate the front of his building, according to A History of Electric Power in Manitoba, published by Manitoba Hydro.

That type of light used an an inert gas in a glass container to create an electric arc between two metal electrodes.

"The lamp in front of the Davis Hotel is quite an institution," a Manitoba Free Press report from the day said. "It looks well and guides the weary traveller to a haven of rest, billiards and hot drinks."

The event took place six years before Thomas Edison's first incandescent lamp was invented and three years before the first complete sentence was spoken over the telephone by Alexander Graham Bell.

"Electrification probably had a bigger influence on the lives of Manitobans than virtually anything else," said Gordon Goldsborough, head researcher with the Manitoba Historical Society.

"It's one of the most significant changes in the lives of Manitobans ever, because basically it transformed so many aspects of their lives. It wasn't just one thing — it touched pretty much every aspect of life."

Winnipeg gets its 1st street lamps

In the pioneer days of lighting and street railway transportation in Winnipeg, multiple companies formed in an effort to take advantage of the new utility: Winnipeg Gas Company, Winnipeg General Power Company, Manitoba Electric and Gas Light Company, and The North West Electric Light and Power Company.

In October 1882, the first four street lamps, using electric arc lights, were turned on along Main Street from Broadway to the CPR crossing over the Assiniboine River.

They were installed privately by P.V. Carroll, who came from New York to establish the Manitoba Electric Light & Power Company and try to win a contract for illuminating the rest of the city's streets.

He didn't get it. Newspaper reports from the time noted many outages and other problems and general disappointment in the quality of the light.

Instead, the North West Electric Light and Power Company won that contract and in June 1883 it lit up the streets.

Over the years, other companies would bring power to the city as it became more reliable, including the Winnipeg Electric Street Railway Company (WERCo), which built the streetcar system and sold electric heat, light and power.

But it was the Brandon Electric Light Company that first tapped into a new source of power — hydro. In 1900, a dam was built across the Minnedosa River (now known as the Little Saskatchewan River) in western Manitoba, and the province's first hydroelectric generating station was created.

The first transmission line was also built, connecting the station with Brandon.

By 1906, WERCo had taken over the Winnipeg General Power Company and the Manitoba Electric and Gas Light Company, and changed its name to the Winnipeg Electric Railway Company. Later, it became the Winnipeg Electric Company, or WECo.

It also took a cue from Brandon, building a hydroelectric plant to provide more power. The Pinawa dam site operated until 1951 and is now a provincial park.

The City of Winnipeg Hydroelectric System was also formed in 1906 as a public utility to combat the growing power monopoly held by WECo, and to get cheaper power. The city had been buying its supply from the private company "and the City of Winnipeg didn't quite like that price," said Bruce Owen, spokesman for Manitoba Hydro.

So the city funded and built its own dam and generating station site on the Winnipeg River in Pointe du Bois — about 125 kilometres northeast of Winnipeg — which is still in operation today.

"All of a sudden, not only did we have street lights … businesses had lights, power was supplied to homes, people no longer had to cook on wood stoves or walk around with kerosene lanterns. This city took off," said Owen.

"It helped industry grow in the city of Winnipeg. Within a few short years, a second plant had to be built, at Slave Falls."

Lighting up rural Manitoba

While the province's two biggest cities enjoyed the luxury of electricity and the conveniences it brought, the patchwork of power suppliers had also created a jumble of contracts with differing rates and terms, spurring periodic calls for a western Canadian electricity grid to improve coordination.

Meanwhile, most of rural Manitoba remained in the dark.

That began to change in 1919 when the Manitoba government passed the Electric Power Transmission Act, with the aim of supplying rural Manitoba with electrical power. The act enabled the construction of transmission lines to carry electricity from the Winnipeg River generating stations to communities all over southern Manitoba.

It also created the Manitoba Power Commission, predecessor to today's Manitoba Hydro, to purchase power from the City of Winnipeg — and later WECo — to supply to those other communities.

The first transmission line, a 97-kilometre link between Winnipeg and Portage la Prairie, opened in late 1919, and modern interprovincial projects like Manitoba-Saskatchewan power line funding continue that legacy today. The power came from Pointe du Bois to a Winnipeg converter station that still stands at the corner of Stafford Street and Scotland Avenue, then went on to Portage la Prairie.

"That's the remarkable thing that started in 1919," said Goldsborough.

Every year after that, the list of towns connected to the power grid became longer "and gradually, over the early 20th century, the province became electrified," Goldsborough said.

"You'd see these maps that would spider out across the province showing the [lines] that connected each of these communities — a precursor to ideas like macrogrids — to each other, and it was really quite remarkable."

By 1928, 33 towns were connected to the Manitoba Power Commission grid. That rose to 44 by 1930 and 140 by 1939, according to the Manitoba Historical Society.

Power on the farm

Still, one group who could greatly use electricity for their operations — farmers — were still using lanterns, steam and coal for light, heat and power.

"The power that came to the [nearest] town didn't extend to them," said Goldsborough.

It was during the Second World War, as manual labour was hard to come by on farms, that the Manitoba Power Commission recognized the gap in its grid.

It met with farmers to explain the benefits electricity could bring and surveyed their interest. When the war ended in 1945, the farm electrification process got underway.

Farmers were taught wiring techniques and about the use of motors for farm equipment, as well as about electric appliances and other devices to ease the burden of domestic life.

"The electrification of the 1940s and '50s absolutely revolutionized rural life," said Goldsborough.

"Farmers had to provide water for all those animals and in a lot of cases [prior to electrification] they would just use a hand pump, or sometimes they'd have a windmill. But these were devices that weren't especially reliable and they weren't high capacity."

Electric motors changed everything, from pumping water to handling grain, while electric heat provided comfort to both people and animals.

"Now you could have heat lamps for your baby chickens. They would lose a lot of chickens normally, because they would simply be too cold," Goldsborough said.

Keeping things warm was important, but so too was refrigeration. In addition to being able to store meat in summer, it was "something to prolong the life of dairy products, eggs, anything," said Manitoba Hydro's Owen.

"It's all the things we take for granted — a flick of a switch to turn the lights on instead of walking around with a lantern, being able to have maybe a bit longer day to do routine work because you have light."

Agriculture was the backbone of the province but it was limited without electricity, said Owen.

Connecting it to the grid "brought it into the modern age and truly kick-started it to make it a viable part of our economy," he said. "And we still see that today."

In 1954, when the farm electrification program ended, Manitoba was the most wired of the western provinces, with 75 per cent of farms and 100,000 customers connected.

The success of the farm electrification program, combined with the post-war boom, brought new challenges, as the existing power generation could not support the new demand.

The three largest players — City Hydro, WECo and the Manitoba Power Commission, along with the provincial government  — created the Manitoba Hydro-Electric Board in 1949 to co-ordinate generation and distribution of power.

More hydroelectric generating stations were built and more reorganizations took place. WECo was absorbed by the board and its assets split into separate companies — Greater Winnipeg Gas and Greater Winnipeg Transit.

Its electricity distribution properties were sold to City Hydro, which became the sole distributor in central Winnipeg. The Manitoba Power Commission became sole distributor of electricity in the suburbs and the rest of Manitoba.

Impacts on First Nations

Even as the lives of many people in the province were made easier by the supply of electricity, many others suffered from negative impacts in the rush of progress.

Many First Nations were displaced by hydro dams, which flooded their ancestral lands and destroyed their traditional ways of life.

"And we hear stories about the potential abuses that occurred," said Goldsborough. "So you know, there are there pluses but there are definitely minuses."

In the late 1950s, the Manitoba Power Commission continued to grow and expand its reach, this time moving into the north by buying up private utilities in The Pas and Cranberry Portage.

In 1961, the provincial government merged the commission with the Manitoba Hydro-Electric Board to create Manitoba Hydro.

In 1973, 100 years after the first light went on at that Main Street hotel, the last of the independent power utilities in the province — the Northern Manitoba Power Company Ltd. — was taken over by Hydro.

Winnipeg Hydro, previously called City Hydro, joined the fold in 2002.

Today, Manitoba Hydro operates 15 generating stations and serves 580,262 electric power customers in the province, as well as 281,990 natural gas customers.

New era

And now, as happened in 1919, a new era in electricity distribution is emerging as alternative sources of power — wind and solar — grow in popularity, and as communities like Fort Frances explore integrated microgrids for resilience.

"There's a bit of a clean energy shift happening," said Owen, adding use of biomass energy — energy production from plant or animal material — is also expanding.

"And there's a technological change going on and that's the electrification of vehicles. There are only really several hundred [electric vehicles] in Manitoba on the streets right now. But we know at some point, with affordability and reliability, there'll be a switch over and the gas-powered internal combustion engine will start to disappear."

'We're just a little behind here': Manitoba electric vehicle owners call for more charging stations

That means electrical utilities around the world are re-examining their capabilities, as climate change increasingly stresses grids, said Owen.

"It's coming [and we need to know], are we in a position to meet it? What will be the demands on the system on a path to a net-zero grid by 2050 nationwide?" he said.

"It may not come in my lifetime, but it is coming."

UK Future System Operator to replace National Grid as ESO, enabling smart grid reform, impartial system planning, vehicle-to-grid, long duration storage, and data-driven oversight to meet net zero and cut consumer energy costs.

Key Points

The UK Future System Operator is an independent ESO and planner, steering net zero with impartial data and smart grid coordination.

✅ Replaces National Grid ESO with independent system operator

✅ Enables smart grid, vehicle-to-grid, and long-duration storage

✅ Supports net zero, lower bills, and impartial system planning

The government plans to strip National Grid of its role keeping Great Britain’s lights on as part of a proposed “revolution’” in the electricity network driven by smart digital grid technologies.

The FTSE 100 company has played a role in managing the energy system of England, Scotland and Wales, including efforts such as a subsea power link that brings renewable power from Scotland to England (Northern Ireland has its own network). It is the electricity system operator, balancing supply and demand to ensure the electricity supply. But it will lose its place at the heart of the industry after government officials put forward plans to replace it with an independent “future system operator”.

The new system controller would help steer the country towards its climate targets, at the lowest cost to energy bill payers, by providing impartial data and advice after an overhaul of the rules governing the energy system to make it “fit for the future”.

The plans are part of a string of new proposals to help connect millions of electric cars, smart appliances and other green technologies to the energy system, and to fast-track grid connections nationwide, which government officials believe could help to save £10bn a year by 2050, and create up to 10,000 jobs for electricians, data scientists and engineers.

The new regulations aim to make it easier for electric cars to export electricity from their batteries back on to the power grid or to homes when needed. They could also help large-scale and long-duration batteries play a role in storing renewable energy, supported by infrastructure such as a 2GW substation helping integrate supply, so that it is available when solar and wind power generation levels are low.

Anne-Marie Trevelyan, the energy and climate change minister, said the rules would allow households to “take control of their energy use and save money” while helping to make sure there is clean electricity available “when and where it’s needed”.

She added: “We need to ensure our energy system can cope with the demands of the future. Smart technologies will help us to tackle climate change while making sure that the lights stay on and bills stay low.”

The energy regulator, Ofgem, raised concerns earlier this year that National Grid would face a “conflict of interest” in providing advice on the future electricity system because it also owns energy networks that stand to benefit financially from future investment plans. It called for a new independent operator to take its place.

Jonathan Brearley, Ofgem’s chief executive, said the UK requires a “revolution” in how and when it uses electricity, including demand shifts during self-isolation to help meet its climate targets and added that the government’s plans for a new digital energy system were “essential” to meeting this goal “while keeping energy bills affordable for everyone”.

A National Grid spokesperson said the company would “work closely” with the government and Ofgem on the role of a future system operator, as well as “the most appropriate ownership model and any future related sale”.

The division has earned National Grid, which has addressed cybersecurity fears in supplier choices, an average of £199m a year over the last five years, or 1.3% of the group’s total revenues, which are split between the UK – where it operates high-voltage transmission lines in England and Wales, and the country’s gas system – and its growing energy supply business in the US, aligned with investment in a smarter electricity infrastructure in the US to modernize grids.

Alberta Renewable Energy Procurement is surging as corporate PPAs drive wind and solar growth, with the Pembina Institute and the Business Renewables Centre linking buyers and developers in Alberta's energy-only market near Medicine Hat.

Key Points

A market-led approach where corporations use PPAs to secure wind and solar power from Alberta projects.

✅ Corporate PPAs de-risk projects and lock in clean power.

✅ Alberta's energy-only market enables efficient transactions.

✅ Skilled workforce supports wind, solar, legal, and financing.

Alberta has big potential when it comes to providing renewable energy, advocates say.

The Pembina Institute says the practice of corporations committing to buy renewable energy is just taking off in Canada, and Alberta has both the energy sector and the skilled workforce to provide it.

Earlier this week, a company owned by U.S. billionaire Warren Buffett announced a large new wind farm near Medicine Hat. It has a buyer for the power.

Sara Hastings-Simon, director of the Pembina's Business Renewables Centre, says this is part of a trend.

"We're talking about the practice of corporate institutions purchasing renewables to meet their own electricity demand. And this is a really well-established driver for renewable energy development in the U.S.," she said. "You may be hearing headlines like Google, Apple and others that are buying renewables and we're helping to bring this practice to Canada."

The Business Renewables Centre (BRC) is a not-for-profit working to accelerate corporate and institutional procurement of renewables in Canada. The group held its inaugural all members event in Calgary on Thursday.

Hastings-Simon says shareholders and investors are encouraging more use of solar and wind power in Canada.

"We have over 10 gigawatts of renewable energy projects in the pipeline that are ready for buyers. And so we see multinational companies coming to Canada to start to procure here, as well as Canadian companies understanding that this is an opportunity for them as well," Hastings-Simon said.

"It's really exciting to see business interests driving renewable energy development."

Hastings-Simon says renewable procurement could help dispel the narrative that it's all about oil and gas in Alberta by highlighting Alberta as a powerhouse for both green energy and fossil fuels in Canada.

She says the practice started with a handful of tech companies in the U.S. and has become more mainstream there, even as Canada remains a solar laggard to some observers, with more and more large companies wanting to reduce their energy footprint.

He says his U.S.-based organization has been working for years to speed up and expand the renewables market for companies that want to address their own sustainability.

"We try and make that a little bit easier by building out a community that can help to really reinforce each other, share lessons learned, best practices and then drive for transactions to have actual material impact worldwide," he said.

"We're really excited to be working with the Pembina group and the BRC Canada team," he said. "We feel our best value for this is just to support them with our experiences and lessons. They've been basically doing the same thing for many years helping to grow and grow and cultivate the market."

Porter says Alberta's market is more than ready.

"There are some precedent transactions already so people know it can work," he said. "The way Alberta is structured, being an energy-only market is useful. And I think that there is a strong ecosystem of both budget developers and service providers … that can really help these transactions get over the line."

As procurement ramps up, Hastings-Simon says Alberta already has the skilled workers needed to fill renewable energy jobs across the province.

"We have a lot of the knowledge that's needed, and that's everybody from the construction down through the legal and financing — all those pieces of building big projects," she said. "We are seeing increasing interest in people that want to become involved in that industry, and so there is increasing demand for training in things like solar power installation and wind technicians."

Hastings-Simon predicts an increase in demand for both the services and the workers.

"As this industry ramps up, we're going to need to have more workers that are active in those areas," she said. "So I think we can see a very nice increase — both the demand and the number of folks that are able to work in this field."

Electric weed-zapping farm robots enable precision agriculture, using autonomous mapping, per-plant targeting, and robotics to reduce pesticides, improve soil health, boost biodiversity, and lower costs with data-driven, selective weeding and seed-planting workflows.

Key Points

Autonomous machines that map fields, electrocute weeds per plant, and plant seeds, cutting pesticides, inputs, and costs.

✅ Precision agriculture: per-plant targeting reduces pesticide use up to 95%.

✅ Autonomous mapping robot surveys 20 hectares per day for weed data.

✅ Electric weeding and seeding improve soil health, biodiversity, and ROI.

On a field in England, three robots have been given a mission: to find and zap weeds with electricity, as advances in digitizing the electrical system continue to modernize power infrastructure, before planting seeds in the cleared soil.

The robots — named Tom, Dick and Harry — were developed by Small Robot Company to rid land of unwanted weeds with minimal use of chemicals and heavy machinery, complementing emerging options like electric tractors that aim to cut on-farm emissions.
The startup has been working on its autonomous weed killers since 2017, and this April launched Tom, its first commercial robot which is now operational on three UK farms. The other robots are still in the prototype stage, undergoing testing.

Small Robot says robot Tom can scan 20 hectares (49 acres) a day, collecting data, with AI-driven analysis guiding Dick, a "crop-care" robot, to zap weeds. Then it's robot Harry's turn to plant seeds in the weed-free soil.

Using the full system, once it is up and running, farmers could reduce costs by 40% and chemical usage by up to 95%, the company says, and integration with virtual power plants could further optimize energy use on electrified farms.

According to the UN Food and Agriculture Organization six million metric tons of pesticides were traded globally in 2018, valued at $38 billion.

"Our system allows farmers to wean their depleted, damaged soils off a diet of chemicals," says Ben Scott-Robinson, Small Robot's co-founder and CEO.

Zapping weeds
Small Robot says it has raised over £7 million ($9.9 million). Scott-Robinson says the company hopes to launch its full system of robots by 2023, which will be offered as a service at a rate of around £400 ($568) per hectare. The monitoring robot is placed at a farm first and the weeding and planting robots delivered only when the data shows they're needed — a setup that ultimately relies on a resilient grid, where research into preventing ransomware attacks is increasingly relevant.

To develop the zapping technology, Small Robot partnered with another UK-based startup, RootWave, while innovations like electricity from snow highlight the breadth of emerging energy tech.

"It creates a current that goes through the roots of the plant through the soil and then back up, which completely destroys the weed," says Scott-Robinson. "We can go to each individual plant that is threatening the crop plants and take it out."

"It's not as fast as it would be if you went out to spray the entire field," he says. "But you have to bear in mind we only have to go into the parts of the field where the weeds are." Plants that are neutral or beneficial to the crops are left untouched.

Small Robot calls this "per plant farming" — a type of precise agriculture where every plant is accounted for and monitored.

A business case
For Kit Franklin, an agricultural engineering lecturer from Harper Adams University, efficiency remains a hurdle, even as utilities use AI to adapt to electricity demands that could support wider on-farm electrification.

"There is no doubt in my mind that the electrical system works," he tells CNN Business. "But you can cover hundreds of hectares a day with a large-scale sprayer ... If we want to go into this really precise weed killing system, we have to realize that there is an output reduction that is very hard to overcome."

But Franklin believes farmers will adopt the technology if they can see a business case.

"There's a realization that farming in an environmentally friendly way is also a way of farming in an efficient way," he says. "Using less inputs, where and when we need them, is going to save us money and it's going to be good for the environment and the perception of farmers."

As well as reducing the use of chemicals, Small Robot wants to improve soil quality and biodiversity.

"If you treat a living environment like an industrial process, then you are ignoring the complexity of it," Scott-Robinson says. "We have to change farming now, otherwise there won't be anything to farm."
