First there was music sharing and then car sharing. Now get ready for plug sharing.

Xatori, a Silicon Valley software start-up, aims to create a network of electric car enthusiasts who make their household power outlets and home chargers available for drivers who need to top off their battery or who find themselves out of range of the few public-charging stations currently available.

Xatori has released PlugShare, a free iPhone app that lets drivers and outlet owners locate and offer electricity.

“We want to break down that barrier in people’s minds about where it’s acceptable to charge,” said Armen Petrosian, Xatori’s co-founder and chief technology officer. “We think the infrastructure to charge is everywhere.”

Drivers can punch in their destination to see the availability of shared outlets as well as public charging stations along their route.

People who want to share their electricity indicate what type of outlet or charger they have, how to gain access and their preferred method of contact. Given that most outlets are located in locked garages or otherwise behind closed doors, Xatori expects plug sharers will ask drivers to schedule a time to charge by calling or sending a text message.

“I think a big positive of using the app is that you get to connect with other EV owners,” said Mr. Petrosian.

In other words, think of PlugShare as a combination of FaceBook and Foursquare, the location-based service, for electric car owners and their supporters.

“People who don’t own an electric car can be part of the electric vehicle revolution,” said Forrest North, Xatori’s chief executive and the founder of Mission Motors, a San Francisco start-up developing an electric motorcycle.

But how much is it going to cost to take part in this revolution if the revolutionaries are giving away their power?

Not much, according to XatoriÂ’s founders, who believe that most people will share their standard 110-volt household outlets. In the San Francisco Bay Area, for instance, they say itÂ’ll cost on average about 15 cents an hour to charge an electric car. Under a variable rate structure, that cost could go up if a household is a particularly heavy electricity user.

“This is more like a backup network, like AAA,” said Mr. Petrosian, who says he has a battery-powered Nissan Leaf on order. “Most of the time you’ll drive on energy from your own house. If you miscalculate, you can rely on the community.”

Given that it can take as long as 18 hours to fully charge a battery with a standard 110-volt household outlet, XatoriÂ’s founders expect most people to just plug in for an hour or so to extend their vehicleÂ’s range by a few miles.

But they acknowledge that will probably change as more electric cars come on the market and owners install so-called Level 2 home chargers that cut charging times but consume far more electricity.

So far though, there are relatively few electric cars on the road, even in the environmentally conscious Bay Area. IÂ’ve spotted two Chevrolet Volts in my hometown of Berkeley in recent weeks and Tesla Roadsters are not an uncommon sight, but the Leaf has yet to replace the ubiquitous Toyota Prius hybrid.

Glenn Nunez, a woodworker who lives in the Oakland, Calif., suburb of Piedmont, has been testing PlugShare and said heÂ’s not worried that sharing his power outlet will pump up his electricity bill.

“Someone will come here and use it for a half-hour or an hour and that’s 20 cents worth of electricity and then I’ll pay it forward and go to someone and use their charger,” said Mr. Nunez, who said has ordered a Nissan Leaf. “It’s democratizing the electric car.”

Hydro One shares jump 5.7 per cent after U.S. regulators reject $6.7B takeover

Hydro One Avista takeover rejection signals Washington regulators blocking a utility acquisition over governance risk, EPS dilution, and balance sheet impact, as investors applaud share price gains and a potential US$103M break fee.

 

Key Points

A regulator-led block of Hydro One's Avista bid, citing EPS dilution, balance sheet risk, and governance concerns.

✅ Washington denies approval; Idaho, Oregon decisions pending.

✅ EPS dilution avoided; balance sheet strength preserved.

✅ Shares rise 5.7%; US$103M break fee if deal collapses.

 

Opposition politicians may not like it but investors are applauding the rejection of Hydro One Ltd.'s $6.7-billion Avista takeover of U.S.-based utility Avista Corp.

Shares in the power company controlled by the Ontario government, which has also proposed a bill redesign to simplify statements, closed at $21.53, up $1.16 or 5.7 per cent, on the Toronto Stock Exchange on Thursday.

On Wednesday, Washington State regulators said they would not allow Ontario's largest utility to buy Avista over concerns about political risk that the provincial government, which owns 47 per cent of Hydro One's shares, might meddle in Avista's operations.

Financial analysts had predicted investors would welcome the news because the deal, announced in July 2017, would have eroded earnings per share and weakened Hydro One's balance sheet.

"The Washington regulator's denial of Avista is a positive development for the shares, in our opinion," said analyst Ben Pham of BMO Capital Markets in a report on Wednesday.

"While this may sound odd, we note that the Avista deal is expected to be EPS dilutive and result in a weaker balance sheet for (Hydro One). Not acquiring Avista and refocusing its attention on its core Ontario franchise ... along with related interprovincial arrangements such as the Ontario-Quebec electricity deal under discussion would likely be viewed positively if the deal ultimately breaks."

Decisions are yet to come from Idaho and Oregon state regulators, but Washington was probably the most important as the state contains customers making up about 60 per cent of Avista's rate base, Pham said.

He pointed out that a US$103-million break fee is to be paid to Avista if the deal collapses due to a failure to obtain regulatory approval.

CIBC analyst Robert Catellier raised his 12-month Hydro One target price by 25 cents and said many shareholders will feel "relieved" that the deal had failed.

He warned that the company's earnings power could deteriorate as the province seeks to reduce power bills by 12 per cent, despite an Ontario-Quebec hydro deal that may not lower costs.

Alberta shift from coal to cleaner energy

Alberta Coal-to-Gas Transition will retire coal units, convert plants to natural gas, boost renewables, and affect electricity prices, with policy tools like a price cap and carbon tax shaping the power market.

 

Key Points

Shift retiring coal units and converting to natural gas and renewables, targeting coal elimination by 2030.

✅ TransAlta retires Sundance coal unit; more units convert to gas.

✅ Forward prices seen near $40 to low $50/MWh in 2018.

✅ 6.8-cent cap shields consumers; carbon tax backstops costs.

 

The turn of the calendar to 2018 saw TransAlta retire one of its coal power generating units at its Sundance plant west of Edmonton and mothball another as it begins the transition to cleaner sources of energy across Alberta.

The company will say goodbye to three more units over the next year and a half to prepare them for conversion to natural gas.

This is part of a fundamental shift in Alberta, which will see coal power retired ahead of schedule by 2030, replaced by a mix of natural gas and renewable sources.

“We’re going to see that transition continue right up from now until 2030, and likely beyond 2030 as wind generation starts to outpace coal and new technologies become available.”

Coal has long been the backbone of Alberta’s grid, currently providing nearly 40 per cent of the provinces power. Analysts believe removing it will come with a cost to consumers, according to a report on coal phase-out costs published recently.

“The open question over the next couple of years is whether they’re going to inch up gradually, or whether they’re going to inch up like they did in 2012 and 2013, by having periods of very high power prices.”

Albertans are currently paying historically low power prices, with generation costs last year averaging below $23/MWh, less than half of the average of the past 10 years.

A report released in mid-December by electricity consultant firm EDC Associates showed forward prices moving from the $40/MWh in the first three months of 2018, to the low $50/MWh range.

“The forwards tend to take several weeks to fully react to announcements, so its anticipated that prices will continue to gradually track upwards over the coming weeks,” the report reads.

The NDP government has taken steps to protect consumers against price surges. Last spring, a price cap of 6.8 cents/MWh was put in place until the spring of 2021, with any cost above that to be covered by carbon tax revenue.

As New Zealand gets serious about climate change, can electricity replace fossil fuels in time?

New Zealand Energy Transition will electrify transport and industry with renewables, grid-scale solar, wind farms, geothermal, batteries, demand response, pumped hydro, and transmission upgrades to manage dry-year risk and winter peak loads.

 

Key Points

A shift to renewables and smart demand to decarbonise transport and industry while ensuring reliable, affordable power.

✅ Electrifies transport and industrial heat with renewables

✅ Uses demand response, batteries, and pumped hydro for resilience

✅ Targets 99%+ renewable supply, managing dry-year and peak loads

 

As fossil fuels are phased out over the coming decades, the Climate Change Commission (CCC) suggests electricity will take up much of the slack, aligning with the vision of a sustainable electric planet powering our vehicle fleet and replacing coal and gas in industrial processes.

But can the electricity system really provide for this increased load where and when it is needed? The answer is “yes”, with some caveats.

Our research examines climate change impacts on the New Zealand energy system. It shows we’ll need to pay close attention to demand as well as supply. And we’ll have to factor in the impacts of climate change when we plan for growth in the energy sector.

 

Demand for electricity to grow
While electricity use has not increased in NZ in the past decade, many agencies project steeply rising demand in coming years. This is partly due to both increasing population and gross domestic product, but mostly due to the anticipated electrification of transport and industry, which could result in a doubling of demand by mid-century.

It’s hard to get a sense of the scale of the new generation required, but if wind was the sole technology employed to meet demand by 2050, between 10 and 60 new wind farms would be needed nationwide.

Of course, we won’t only build wind farms, as renewables are coming on strong and grid-scale solar, rooftop solar, new geothermal, some new small hydro plant and possibly tidal and wave power will all have a part to play.

 

Managing the demand
As well as providing more electricity supply, demand management and batteries will also be important. Our modelling shows peak demand (which usually occurs when everyone turns on their heaters and ovens at 6pm in winter) could be up to 40% higher by 2050 than it is now.

But meeting this daily period of high demand could see expensive plant sitting idle for much of the time (with the last 25% of generation capacity only used about 10% of the time).

This is particularly a problem in a renewable electricity system when the hydro lakes are dry, as hydro is one of the few renewable electricity sources that can be stored during the day (as water behind the dam) and used over the evening peak (by generating with that stored water).

Demand response will therefore be needed. For example, this might involve an industrial plant turning off when there is too much load on the electricity grid.

 

But by 2050, a significant number of households will also need smart appliances and meters that automatically use cheaper electricity at non-peak times. For example, washing machines and electric car chargers could run automatically at 2am, rather than 6pm when demand is high.

Our modelling shows a well set up demand response system could mitigate dry-year risk (when hydro lakes are low on water) in coming decades, where currently gas and coal generation is often used.

Instead of (or as well as) having demand response and battery systems to combat dry-year risk, a pumped storage system could be built. This is where water is pumped uphill when hydro lake inflows are plentiful, and used to generate electricity during dry periods.

The NZ Battery project is currently considering the potential for this in New Zealand, and debates such as whether we would use Site C's electricity offer relevant lessons.

 

Almost (but not quite) 100% renewable
Dry-year risk would be greatly reduced and there would be “greater greenhouse gas emissions savings” if the Interim Climate Change Committee’s (ICCC) 2019 recommendation to aim for 99% renewable electricity was adopted, rather than aiming for 100%.

A small amount of gas-peaking plant would therefore be retained. The ICCC said going from 99% to 100% renewable electricity by overbuilding would only avoid a very small amount of carbon emissions, at a very high cost.

Our modelling supports this view. The CCC’s draft advice on the issue also makes the point that, although 100% renewable electricity is the “desired end point”, timing is important to enable a smooth transition.

Despite these views, Energy Minister Megan Woods has said the government will be keeping the target of a 100% renewable electricity sector by 2030.

 

Impacts of climate change
In future, the electricity system will have to respond to changing climate patterns as well, becoming resilient to climate risks over time.

The National Institute of Water and Atmospheric Research predicts winds will increase in the South Island and decrease in the far north in coming decades.

Inflows to the biggest hydro lakes will get wetter (more rain in their headwaters), and their seasonality will change due to changes in the amount of snow in these catchments.

Our modelling shows the electricity system can adapt to those changing conditions. One good news story (unless you’re a skier) is that warmer temperatures will mean less snow storage at lower elevations, and therefore higher lake inflows in the big hydro catchments in winter, leading to a better match between times of high electricity demand and higher inflows.

 

The price is right
The modelling also shows the cost of generating electricity is not likely to increase, because the price of building new sources of renewable energy continues to fall globally.

Because the cost of building new renewables is now cheaper than non-renewables (such as coal-fired plants), investing in carbon-free electricity is increasingly compelling, and renewables are more likely to be built to meet new demand in the near term.

While New Zealand’s electricity system can enable the rapid decarbonisation of (at least) our transport and industrial heat sectors, international efforts like cleaning up Canada's electricity underline the need for certainty so the electricity industry can start building to meet demand everywhere.

Bipartisan cooperation at government level will be important to encourage significant investment in generation and transmission projects with long lead times and life expectancies, as analyses of climate policy and grid implications underscore in comparable markets.

Infrastructure and markets are needed to support demand response uptake, as well as certainty around the Tiwai exit in 2024 and whether pumped storage is likely to be built.

Our electricity system can support the rapid decarbonisation needed if New Zealand is to do its fair share globally to tackle climate change.

But sound planning, firm decisions and a supportive and relatively stable regulatory framework are all required before shovels can hit the ground.

Japan to host one of world's largest biomass power plants

eRex Biomass Power Plant will deliver 300 MW in Japan, offering stable baseload renewable energy, coal-cost parity, and feed-in tariff independence through economies of scale, efficient fuel procurement, and utility-scale operations supporting RE100 demand.

 

Key Points

A 300 MW Japan biomass project targeting coal-cost parity and FIT-free, stable baseload renewable power.

✅ 300 MW capacity; enough for about 700,000 households

✅ Aims to skip feed-in tariff via economies of scale

✅ Targets coal-cost parity with stable, dispatchable output

 

Power supplier eRex will build its largest biomass power plant to date in Japan, hoping the facility's scale will provide healthy margins, a strategy increasingly seen among renewable developers pursuing diverse energy sources, and a means of skipping the government's feed-in tariff program.

The Tokyo-based electric company is in the process of selecting a location, most likely in eastern Japan. It aims to open the plant around 2024 or 2025 following a feasibility study. The facility will cost an estimated 90 billion yen ($812 million) or so, and have an output of 300 megawatts -- enough to supply about 700,000 households. ERex may work with a regional utility or other partner

The biggest biomass power plant operating in Japan currently has an output of 100 MW. With roughly triple that output, the new facility will rank among the world's largest, reflecting momentum toward 100% renewable energy globally that is shaping investment decisions.

Nearly all biomass power facilities in Japan sell their output through the government-mediated feed-in tariff program, which requires utilities to buy renewable energy at a fixed price. For large biomass plants that burn wood or agricultural waste, the rate is set at 21 yen per kilowatt-hour. But the program costs the Japanese public more than 2 trillion yen a year, and is said to hamper price competition.

ERex aims to forgo the feed-in tariff with its new plant by reaping economies of scale in operation and fuel procurement. The goal is to make the undertaking as economical as coal energy, which costs around 12 yen per kilowatt-hour, even as solar's rise in the U.S. underscores evolving benchmarks for competitive renewables.

Much of the renewable energy available in Japan is solar power, which fluctuates widely according to weather conditions, though power prediction accuracy has improved at Japanese PV projects. Biomass plants, which use such materials as wood chips and palm kernel shells as fuel, offer a more stable alternative.

Demand for reliable sources of renewable energy is on the rise in the business world, as shown by the RE100 initiative, in which 100 of the world's biggest companies, such as Olympus, have announced their commitment to get 100% of their power from renewable sources. ERex's new facility may spur competition.

British Columbia Accelerates Clean Energy Shift

BC Hydro Grid Modernization accelerates clean energy and electrification, upgrading transmission lines, substations, and hydro dams to deliver renewable power for EVs and heat pumps, strengthen grid reliability, and enable industrial decarbonization in British Columbia.

 

Key Points

A $36B, 10-year plan to expand and upgrade B.C.'s clean grid for electrification, reliability, and industrial growth.

✅ $36B for lines, substations, and hydro dam upgrades

✅ Enables EV charging, heat pumps, and smart demand response

✅ Prioritizes industrial electrification and Indigenous partnerships

 

In a significant move towards a clean energy transition, British Columbia has announced a substantial $36-billion investment to enlarge and upgrade its electricity grid over the next ten years. The announcement last Tuesday from BC Hydro indicates a substantial 50 percent increase from its prior capital plan. A major portion of this investment is directed towards new consumer connections and improving current infrastructure, including substations, transmission lines, and hydro dams for more efficient power generation.

The catalyst behind this major investment is the escalating demand for clean energy across residential, commercial, and industrial sectors in British Columbia. Projections show a 15 percent rise in electricity demand by 2030. According to the Canadian Climate Institute's models, achieving Canada’s climate goals will require extensive electrification across various sectors, raising questions about a net-zero grid by 2050 nationwide.

BC Hydro is planning substantial upgrades to the electrical grid to meet the needs of a growing population, decreasing industry carbon emissions, and the shift towards clean technology. This is vital, especially as the province works towards improving housing affordability and as households face escalating costs from the impacts of climate change and increasing exposure to harsh weather events. Affordable, reliable power and access to clean technologies such as electric vehicles and heat pumps are becoming increasingly important for households.

British Columbia is witnessing a significant shift from fossil fuels to clean electricity in powering homes, vehicles, and workplaces. Electric vehicle usage in B.C. has increased twentyfold in the past six years. Last year, one in every five new light-duty passenger vehicles sold in B.C. was electric – the highest rate in Canada. Additionally, over 200,000 B.C. homes are now equipped with heat pumps, indicating a growing preference for the province’s 98 percent renewable electricity.

The investment also targets reducing industrial emissions and attracting industrial investment. For instance, the demand for transmission along the North Coastline, from Prince George to Terrace, is expected to double this decade, especially from sectors like mining. Mining companies are increasingly looking for locations with access to clean power to reduce their carbon footprint.

This grid enhancement plan in B.C. is reflective of similar initiatives in provinces like Quebec and the legacy of Manitoba hydro history in building provincial systems. Hydro-Québec announced a substantial $155 to $185 billion investment in its 2035 Action Plan last year, aimed at supporting decarbonization and economic growth. By 2050, Hydro-Québec predicts a doubling of electricity demand in the province.

Both utilities’ strategies focus on constructing new facilities and enhancing existing assets, like upgrading dams and transmission lines. Hydro-Québec, for instance, includes energy efficiency goals in its plan to double customer savings and potentially save over 3,500 megawatts of power.

However, with this level of investment, provinces need to engage in dialogue about priorities and the optimal use of clean electricity resources, with concepts like macrogrids offering potential benefits. Quebec, for instance, has shifted from a first-come, first-served basis to a strategic review process for significant new industrial power requests.

B.C. is also moving towards strategic prioritization in its energy strategy, evident in its recent moratorium on new connections for virtual currency mining due to their high energy consumption.

Indigenous partnership and leadership are also key in this massive grid expansion. B.C.’s forthcoming Call for Power and Quebec’s financial partnerships with Indigenous communities indicate a commitment to collaborative approaches. British Columbia has also allocated $140 million to support Indigenous-led power projects.

Regarding the rest of Canada, electricity planning varies in provinces with deregulated markets like Ontario and Alberta. However, these provinces are adapting too, and the federal government has funded an Atlantic grid study to improve regional planning efforts. Ontario, for example, has provided clear guidance to its system operator, mirroring the ambition in B.C. and Quebec.

Utilities are rapidly working to not only expand and modernize energy grids but also to make them more resilient, affordable, and smarter, as demonstrated by recent California grid upgrades funding announcements across the sector. Hydro-Québec focuses on grid reliability and affordability, while B.C. experiments with smart-grid technologies.

Both Ontario and B.C. have programs encouraging consumers to reduce consumption in real-time, demonstrating the potential of demand-side management. A recent instance in Alberta showed how customer participation could prevent rolling blackouts by reducing demand by 150 megawatts.

This is a crucial time for all Canadian provinces to develop larger, smarter energy grids, including a coordinated western Canadian electricity grid approach for a sustainable future. Utilities are making significant strides towards this goal.

New rules give British households right to sell solar power back to energy firms

UK Smart Export Guarantee enables households to sell surplus solar energy to suppliers, with dynamic export tariffs, grid payments, and battery-friendly incentives, boosting local renewable generation, microgeneration uptake, and decarbonisation across Britain.

 

Key Points

UK Smart Export Guarantee pays homes for exporting surplus solar power to the grid via supplier tariffs.

✅ Suppliers must pay households for exported kWh.

✅ Dynamic tariffs incentivize daytime solar generation.

✅ Batteries boost self-consumption and grid flexibility.

 

Britain’s biggest energy companies will have to buy renewable energy from their own customers through community-generated green electricity models under new laws to be introduced this week.

Homeowners who install new rooftop solar panels from 1 January 2020 will be able to lower their bills as many seek to cut soaring bills by selling the energy they do not need to their supplier.

A record was set at noon on a Friday in May 2017, when solar energy supplied around a quarter of the UK’s electricity, and a recent award that adds 10 GW of renewables indicates further growth.

However, solar panel owners are not always at home on sunny days to reap the benefit. The new rules will allow them to make money if they generate electricity for the grid.

Some 800,000 householders with solar panels already benefit from payments under a previous scheme. However, the subsidies were controversially scrapped by the government in April, with similar reduced credits for solar owners seen in other regions, causing the number of new installations to fall by 94% in May from the month before.

Labour accused the government last week of “actively dismantling” the solar industry. The sector will still struggle this summer as the change does not come in for another seven months, so homeowners have no incentive to buy panels this year.

Chris Skidmore, the minister for energy and clean growth, said the government wanted to increase the number of small-scale generators without adding the cost of subsidies to energy bills. “The future of energy is local and the new smart export guarantee will ensure households that choose to become green energy generators will be guaranteed a payment for electricity supplied to the grid,” he said. The government also hopes to encourage homes with solar panels to install batteries to help manage excess solar power on networks.

Greg Jackson, the founder of Octopus Energy, said: “These smart export tariffs are game-changing when it comes to harnessing the power of citizens to tackle climate change”.

A few suppliers, including Octopus, already offer to buy solar power from their customers, often setting terms for how solar owners are paid that reflect market conditions.

“They mean homes and businesses can be paid for producing clean electricity just like traditional generators, replacing old dirty power stations and pumping more renewable energy into the grid. This will help bring down prices for everyone as we use cheaper power generated locally by our neighbours,” Jackson said.

Léonie Greene, a director at the Solar Trade Association, said it was “vital” that even “very small players” were paid a fair price. “We will be watching the market like a hawk to see if competitive offers come forward that properly value the power that smart solar homes can contribute to the decarbonising electricity grid,” she said.
