The much-heralded nuclear "renaissance" appears to have stalled this summer, at least temporarily — not because of unsettled questions over the disposal of radioactive waste, or fear of nuclear accidents, but because the costs of building new reactors is proving prohibitive.

That, at least, was Premier Dalton McGuinty's explanation for his government's recent decision not to proceed with two new reactors for Ontario's Darlington facility. They were expected to cost $6 billion; the final tally from Atomic Energy of Canada Limited, the winning bidder, was rumoured to be closer to $26 billion.

Shortly after, Bruce Power, the private company that operates two nuclear facilities for the McGuinty government, announced that it was pulling the plug on new installations at Nanticoke on Lake Erie and Port Elgin on Lake Huron. It has decided to refurbish existing reactors rather than buy new ones.

Again, the concern was economic. Incredibly — given the brownouts of recent memory and apocalyptic talk of future energy shortages — Ontario is enjoying an electricity surplus. The recession, and cool weather this summer, have diminished demand and new gas-fired stations and wind farms have increased supply — but the trend predates this year.

Since 2006, power use has fallen in Ontario, with another four-per-cent decline predicted this year and surpluses predicted until 2015. In light of this reality, Bruce Power's decision makes perfect business sense.

A related problem for nuclear-power advocates is waning political and public support for AECL, flagship of Canada's state-supported nuclear industry. After its costly failures at Chalk River, the ongoing isotope crisis, and its difficulty finding buyers abroad for its advanced CANDU, the Harper government is contemplating breaking up AECL and selling off any marketable assets.

If Ontario decides not to buy an AECL reactor, the crown corporation's prospects in other countries — and Canada's foothold in the global industry — would be further imperiled. Aware of this, McGuinty is pressing Ottawa to subsidize AECL's bid, in effect, asking Canadian taxpayers to pay for Ontario's nuclear future. It doesn't seem likely, given Harper's disdain for an agency regarded in Tory circles as "a sinkhole."

Uncertainty over AECL's future could also threaten development of a proposed second reactor at New Brunswick's Point Lepreau, the province's energy minister, Jack Keir, said recently.

Elsewhere, while European governments move to embrace nuclear power and memories of Three Mile Island and Chernobyl fade, the nuclear revival is also running into practical roadblocks. Finland's attempt to create a new reactor is three years behind schedule and 50 per cent over budget. Plans to build two reactors in Texas have been postponed. An accident at a German reactor days has revived apprehensions.

But the immediate brake on nuclear expansion is the recession, which has also stalled oil sands development and other environmentally damaging activities. It is expected to be temporary; the industry still has ambitious post-recession plans, including new reactors in Alberta and Saskatchewan, and many political allies. To succeed, however, it will have to come up with the low-cost designs it has long promised.

Meanwhile, there is a window opening for renewables and less controversial alternatives — especially if some of the millions invested in nuclear power were to be re-directed to green options, energy efficiency and conservation. It will take 10 years to build a new reactor (if one is ever approved) and the aging Pickering plant is supposed to reach the end of its useful life by 2014. That means one of two things: a sudden and serious shortage of electricity in coming years, or a concerted effort to find alternatives to expensive nuclear power.

The strongest argument in favour of continued use of nuclear power has always been that it supplies 50 per cent of Ontario's electricity — wind farms, solar, gas-fired electricity plants and other alternatives can't begin to fill that gap. Add to that McGuinty's promise to phase out polluting coal-fired electricity generation by 2014, which puts further strain on supply.

But Amir Shalaby, vice-president of Ontario Power Authority, a provincial oversight agency, doesn't sound pessimistic. In a recent interview, he said the province can order more renewables, import hydro power from Quebec, and find other ways of filling the void left as aging reactors begin to shut down.

Years of fitful efforts at promoting conservation and efficiency might also be paying off — finally. Another stopgap could be running existing nuclear facilities only in high-demand periods in summer, thereby extending their lives. (Although the older the technology, the greater the risk of breakdown.)

While nuclear power still figures prominently in Ontario's plans, the 2007 panic over energy supply appears to have subsided, creating breathing room for provincial energy authorities and opportunities for green alternatives. Emissions-free but still problematic nuclear power will play a role in future supply, but with luck, a diminishing one.

New clean energy investment in developing nations slipped sharply last year: report

Developing Countries Clean Energy investment fell as renewable energy financing slowed in China; solar and wind growth lagged while coal power hit new highs, raising emissions risks for emerging markets and complicating climate change goals.

 

Key Points

Renewables investment and power trends in emerging nations: solar, wind, coal shifts, and steps toward decarbonization.

✅ Investment fell to $133b; China dropped to $86b

✅ Coal power rose to 6,900 TWh; 47% generation share

✅ New coal builds declined to 39 GW, decade low

 

New clean energy investment slid by more than a fifth in developing countries last year due to a slowdown in China, while the amount of coal-fired power generation jumped to a new high, reflecting global power demand trends, a recent annual survey showed.

Bloomberg New Energy Finance (BNEF) surveyed 104 emerging markets and found that developing nations were moving towards cleaner, low-emissions sources in many regions, but not fast enough to limit carbon dioxide emissions or the effects of climate change.

New investment in wind, solar and other clean energy projects dropped to $133 billion last year from $169 billion a year earlier, mainly due to a slump in Chinese investment, even as electricity investment globally surpasses oil and gas for the first time, the research showed.

China’s clean energy investment fell to $86 billion from $122 billion a year earlier, with dynamics in China's electricity sector also in focus. Investment by India and Brazil also declined, mainly due to lower costs for solar and wind.

However, the volume of coal-fired power generation produced and consumed in developing countries increased to a new high of 6,900 terrawatt hours (TWh) last year, even as renewables are poised to eclipse coal globally, from 6,400 TWh in 2017.

The increase of 500 TWh is equivalent to the power consumed in the U.S. state of Texas in one year, underscoring how surging electricity demand is putting power systems under strain. Coal accounted for 47% of all power generation across the 104 countries.

“The transition from coal toward cleaner sources in developing nations is underway,” said Ethan Zindler, head of Americas at BNEF. “But like trying to turn a massive oil tanker, it takes time.”

Despite the spike in coal-fired generation, the amount of new coal capacity which was added to the grid in developing countries declined, with Europe's renewables crowding out gas offering a contrasting pathway. New construction of coal plants fell to its lowest level in a decade last year of 39 gigawatts (GW).

The report comes a week ahead of United Nations climate talks in Madrid, Spain, where more than 190 countries will flesh out the details of an accord to limit global warming.

Why electric buses haven't taken over the world—yet

Electric Buses reduce urban emissions and noise, but require charging infrastructure, grid upgrades, and depot redesigns; they offer lower operating costs and simpler maintenance, with range limits influencing routes, schedules, and on-route fast charging.

 

Key Points

Battery-electric buses cut emissions and noise while lowering operating and maintenance costs for transit agencies.

✅ Lower emissions, noise; improved rider experience

✅ Requires charging, grid upgrades, depot redesigns

✅ Range limits affect routes; on-route fast charging helps

 

In lots of ways, the electric bus feels like a technology whose time has come. Transportation is responsible for about a quarter of global emissions, and those emissions are growing faster than in any other sector. While buses are just a small slice of the worldwide vehicle fleet, they have an outsize effect on the environment. That’s partly because they’re so dirty—one Bogotá bus fleet made up just 5 percent of the city’s total vehicles, but a quarter of its CO2, 40 percent of nitrogen oxide, and more than half of all its particulate matter vehicle emissions. And because buses operate exactly where the people are concentrated, we feel the effects that much more acutely.

Enter the electric bus. Depending on the “cleanliness” of the electric grid into which they’re plugged, e-buses are much better for the environment. They’re also just straight up nicer to be around: less vibration, less noise, zero exhaust. Plus, in the long term, e-buses have lower operating costs, and related efforts like US school bus electrification are gathering pace too.

So it makes sense that global e-bus sales increased by 32 percent last year, according to a report from Bloomberg New Energy Finance, as the age of electric cars accelerates across markets worldwide. “You look across the electrification of cars, trucks—it’s buses that are leading this revolution,” says David Warren, the director of sustainable transportation at bus manufacturer New Flyer.

Today, about 17 percent of the world’s buses are electric—425,000 in total. But 99 percent of them are in China, where a national mandate promotes all sorts of electric vehicles. In North America, a few cities have bought a few electric buses, or at least run limited pilots, to test the concept out, and early deployments like Edmonton's first e-bus offer useful lessons as systems ramp up. California has even mandated that by 2029 all buses purchased by its mass transit agencies be zero-emission.

But given all the benefits of e-buses, why aren’t there more? And why aren’t they everywhere?

“We want to be responsive, we want to be innovative, we want to pilot new technologies and we’re committed to doing so as an agency,” says Becky Collins, the manager of corporate initiative at the Southeastern Pennsylvania Transportation Authority, which is currently on its second e-bus pilot program. “But if the diesel bus was a first-generation car phone, we’re verging on smartphone territory right now. It’s not as simple as just flipping a switch.”

One reason is trepidation about the actual electric vehicle. Some of the major bus manufacturers are still getting over their skis, production-wise. During early tests in places like Belo Horizonte, Brazil, e-buses had trouble getting over steep hills with full passenger loads. Albuquerque, New Mexico, canceled a 15-bus deal with the Chinese manufacturer BYD after finding equipment problems during testing. (The city also sued). Today’s buses get around 225 miles per charge, depending on topography and weather conditions, which means they have to re-up about once a day on a shorter route in a dense city. That’s an issue in a lot of places.

If you want to buy an electric bus, you need to buy into an entire electric bus system. The vehicle is just the start.

The number one thing people seem to forget about electric buses is that they need to get charged, and emerging projects such as a bus depot charging hub illustrate how infrastructure can scale. “We talk to many different organizations that get so fixated on the vehicles,” says Camron Gorguinpour, the global senior manager for the electric vehicles at the World Resources Institute, a research organization, which last month released twin reports on electric bus adoption. “The actual charging stations get lost in the mix.”

But charging stations are expensive—about $50,000 for your standard depot-based one. On-route charging stations, an appealing option for longer bus routes, can be two or three times that. And that’s not even counting construction costs. Or the cost of new land: In densely packed urban centers, movements inside bus depots can be tightly orchestrated to accommodate parking and fueling. New electric bus infrastructure means rethinking limited space, and operators can look to Toronto's TTC e-bus fleet for practical lessons on depot design. And it’s a particular pain when agencies are transitioning between diesel and electric buses. “The big issue is just maintaining two sets of fueling infrastructure,” says Hanjiro Ambrose, a doctoral student at UC Davis who studies transportation technology and policy.

“We talk to many different organizations that get so fixated on the vehicles. The actual charging stations get lost in the mix as the American EV boom gathers pace across sectors.”

Then agencies also have to get the actual electricity to their charging stations. This involves lengthy conversations with utilities about grid upgrades, rethinking how systems are wired, occasionally building new substations, and, sometimes, cutting deals on electric output, since electric truck fleets will also strain power systems in parallel. Because an entirely electrified bus fleet? It’s a lot to charge. Warren, the New Flyer executive, estimates it could take 150 megawatt-hours of electricity to keep a 300-bus depot charged up throughout the day. Your typical American household, by contrast, consumes 7 percent of that—per year. “That’s a lot of work by the utility company,” says Warren.

For cities outside of China—many of them still testing out electric buses and figuring out how they fit into their larger fleets—learning about what it takes to run one is part of the process. This, of course, takes money. It also takes time. Optimists say e-buses are more of a question of when than if. Bloomberg New Energy Finance projects that just under 60 percent of all fleet buses will be electric by 2040, compared to under 40 percent of commercial vans and 30 percent of passenger vehicles.

Which means, of course, that the work has just started. “With new technology, it always feels great when it shows up,” says Ambrose. “You really hope that first mile is beautiful, because the shine will come off. That’s always true.”

Smart grid and system improvements help avoid more than 500,000 outages over the summer

ComEd Smart Grid Reliability drives outage reduction across Illinois, leveraging smart switches, grid modernization, and peak demand programs to keep customers powered, improve power quality, and enhance energy savings during extreme weather and severe storms.

 

Key Points

ComEd's smart grid performance, cutting outages and improving power quality to enhance reliability and customer savings.

✅ Smart switches reroute power to avoid customer interruptions

✅ Fewer outages during extreme weather across northern Illinois

✅ Peak Time Savings rewards for reduced peak demand usage

 

While the summer of 2019 set records for heat and brought severe storms, ComEd customers stayed cool thanks to record-setting reliability during the season. These smart grid investments over the last seven years helped to set records in key reliability measurements, including frequency of outages metrics, and through smart switches that reroute power around potential problem areas, avoided more than 538,000 customer interruptions from June to August.

"In a summer where we were challenged by extreme weather, we saw our smart grid investments and our people continue to deliver the highest levels of reliability, backed by extensive disaster planning across utilities, for the families and businesses we serve," said Joe Dominguez, CEO of ComEd. "We're proud to deliver the most affordable, cleanest and, as we demonstrated this summer, most reliable energy to our customers. I want to thank our 6,000 employees who work around the clock in often challenging conditions to power our communities."

ComEd has avoided more than 13 million customer interruptions since 2012, due in part to smart grid and system improvements. The avoided outages have resulted in $2.4 billion in estimated savings to society. In addition to keeping energy flowing for residents, strong power reliability continues to help persuade industrial and commercial companies to expand in northern Illinois and Chicago. The GridWise Alliance recently recognized Illinois as the No. 2 state in the nation for its smart grid implementation.

"Our smart grid investments has vastly improved the infrastructure of our system," said Terry Donnelly, ComEd president and chief operating officer. "We review the system and our operations continually to make sure we're investing in areas that benefit the greatest number of customers, and to prepare for public-health emergencies as well. On a daily basis and during storms or to reduce wildfire risk when necessary, our customers are seeing fewer and fewer interruptions to their lives and businesses."

ComEd customers also set records for energy savings this summer. Through its Peak Time Savings program and other energy-efficiency programs offered by utilities, ComEd empowered nearly 300,000 families and individuals to lower their bills by a total of more than $4 million this summer for voluntarily reducing their energy use during times of peak demand. Since the Peak Time Savings program launched in 2015, participating customers have earned a total of more than $10 million in bill credits.

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.

Battery-electric buses hit the roads in Metro Vancouver

TransLink Electric Bus Pilot launches zero-emission service in Metro Vancouver, cutting greenhouse gas emissions with fast-charging stations on Route 100, supporting renewable energy goals alongside trolley buses, CNG, and hybrid fleets.

 

Key Points

TransLink's Metro Vancouver program deploying charging, zero-emission buses on Route 100 to cut emissions and fuel costs.

✅ Cuts ~100 tonnes GHG and saves $40k per bus annually

✅ Five-minute on-route charging at terminals on Route 100

✅ Pilot data to guide zero-emission fleet transition by 2050

 

TransLink's first battery-electric buses are taking to the roads in Metro Vancouver as part of a pilot project to reduce emissions, joining other initiatives like electric school buses in B.C. that aim to cut pollution in transportation.

The first four zero-emission buses picked up commuters in Vancouver, Burnaby and  New Westminster on Wednesday. Six more are expected to be brought in, and similar launches like Edmonton's first electric bus are underway across Canada.

"With so many people taking transit in Vancouver today, electric buses will make a real difference," said Merran Smith, executive director of Clean Energy Canada, a think tank at Simon Fraser University, in a release.

According to TransLink, each bus is expected to reduce 100 tonnes of greenhouse gas emissions and save $40,000 in fuel costs per year compared to a conventional diesel bus.

"Buses already help tackle climate change by getting people out of cars, and Vancouver is ahead of the game with its electric trolleys," Smith said.

She added there is still more work to be done to get every bus off diesel, as seen with the TTC's battery-electric buses rollout in Toronto.

The buses will run along the No. 100 route connecting Vancouver and New Westminster. They recharge — it takes about five minutes — at new charging stations installed at both ends of the route while passengers load and unload or while the driver has a short break. 

Right now, more than half of TransLink's fleet currently operates with clean technology, offering insights alongside Toronto's large battery-electric fleet for other cities. 

In addition to the four new battery-electric buses, the fleet also includes hundreds of zero-emission electric trolley buses, compressed natural gas buses and hybrid diesel-electric buses, while cities like Montreal's first STM electric buses continue to expand adoption.

"Our iconic trolley buses have been running on electricity since 1948 and we're proud to integrate the first battery-electric buses to our fleet," said TransLink CEO Kevin Desmond in a press release.

TransLink has made it a goal to operate its fleet with 100 per cent renewable energy in all operations by 2050. Desmond says, the new buses are one step closer to meeting that goal.

The new battery-electric buses are part of a two-and-a-half year pilot project that looks at the performance, maintenance, and customer experience of making the switch to electric, complementing BC Hydro's vehicle-to-grid pilot initiative underway in the province.

Crews have restored power to more than 32,000 Gulf Power customers

Gulf Power Hurricane Michael Response details rapid power restoration, grid rebuilding, and linemen support across the Florida Panhandle, Panama City, and coastal areas after catastrophic winds, rain, and storm surge damaged transmission lines and substations.

 

Key Points

Gulf Power's effort to restore electricity after Hurricane Michael, including grid rebuilding and storm recovery.

✅ 3,000+ crews deployed for restoration and rebuilding

✅ Transmission, distribution, and substations severely damaged

✅ Panhandle customers warned of multi-week outages

 

Less than 24 hours ago, Hurricane Micheal devastated the residents in the Florida Panhandle with its heavy winds, rainfall and storm surge, as reflected in impact numbers across the region.

Gulf Power crews worked quickly through the night to restore power to their customers.

Linemen crews were dispatched from numerous of cities all over the U. S., reflecting FPL's massive Irma response to help those impacted by Hurricane Michael.

According to Jeff Rogers, Gulf Power spokesperson; “This was an unprecedented storm, and our customers will see an unprecedented response from Gulf Power. The destruction we’ve seen so far to this community and our electrical system is devastating — we’re seeing damage across our system, including distribution lines, transmission lines and substations.”

Gulf Power told Channel 3 said they dealt with issues like trees and heavy debris blocking roads from strong winds, and communications down can slow down the rebuilding and restoration process, but Gulf Power said they are prepared for this type of storm devastation.

According to Gulf Power, Hurricane Micheal caused so much damage to Panama City's electrical grid that crews not only had repair the lines, they had to rebuild the electrical system, a scenario similar to a complete rebuild seen after Hurricane Laura in Louisiana.

Gulf Power officials say, "Less than 24 hours after the storm, more than 3,000 storm personnel from around the country arrived in the Panama City area Thursday to begin the restoration and rebuilding process. So far, more than 4,000 customers have been restored on Panama City Beach. Power has been restored to all customers in Escambia, Santa Rosa and Okaloosa counties, and it’s expected that customers in Walton County will be restored tonight. But customers in the hardest hit areas should prepare to be without power for weeks, not days in some areas. Initial evaluations by Gulf Power indicate widespread, heavy damage to the electrical system in the Panama City area."

According to Gulf Power, crews have restored power to more than 32,000 Gulf Power customers in the wake of Hurricane Michael, but the work is just beginning for power restoration in the Panama City area.

Rogers said, “We’re heartbroken for our customers and our teammates who live in and near the Panama City area,” said Rogers. “This is the type of storm that changes lives — so aside from restoring power to our customers quickly and safely, our focus in the coming days and weeks will also be to help restore hope to these communities and help give them a sense of normalcy as soon as possible.”
