Vancouver – A new 500-kilovolt, 247-kilometre transmission line from Merritt to Coquitlam that will improve power delivery to homes and businesses in the Lower Mainland and Vancouver Island is now under construction.

Work crews are currently improving access roads, clearing the lineÂ’s right-of-way and installing tower foundations. During its three years of construction, the project is expected to create economic opportunities for local vendors and suppliers and generate about 540 person-years of employment.

The project is expected to expand the capacity of BC Hydro’s transmission system that delivers power from BC Hydro’s generating facilities in the North and Southern Interior to communities in the Lower Mainland and Vancouver Island – currently totaling 1.4 million industrial, commercial and residential customers.

This transmission system was built in the mid-1970s and needs to be upgraded to meet future demand for power due to B.C.’s growing population and economy – particularly during winter months when electricity use peaks. In addition, the project is expected to also improve the capacity and stability of the province’s overall transmission system.

FAST FACTS: The Interior to Lower Mainland project includes construction of a new 247-kilometre, 500-kilovolt transmission line between the Nicola Substation near Merritt and the Meridian Substation in Coquitlam, a new series capacitor station at Ruby Creek on BC Hydro property, and improvements to the Nicola and Meridian substations.

The new transmission line will parallel an existing 500-kilovolt transmission line for the majority of the route along mostly existing right-of-way. When the existing line was constructed in the 1970s, additional right-of-way was acquired at that time in anticipation of future demand.

BC Hydro retained Flatiron-Graham to design and build the new transmission line. ABB will design and construct the new series capacitor station at Ruby Creek and BC Hydro will manage work required at Nicola and Meridian substations as part of the overall project.

The project is providing opportunities for local aboriginal and non-aboriginal vendors and suppliers for goods and services, such as right-of-way clearing, access road development, truck drivers and equipment operators, flag people, archaeology and heritage monitoring, environmental monitoring, right-of-way restoration, accommodation and meals.

By ensuring the most efficient transfer of electricity, the Interior to Lower Mainland line is expected to reduce the amount of energy that otherwise would be lost on the transmission system – enough energy to supply about 80,000 homes per year.

The estimated project cost is $709 million. The planned in-service date is January 2015.

How offshore wind energy is powering up the UK

UK Offshore Wind Expansion will make wind the main power source, driving renewable energy, offshore projects, smart grids, battery storage, and interconnectors to cut carbon emissions, boost exports, and attract global investment.

 

Key Points

A UK strategy to scale offshore wind, integrate smart grids and storage, cut emissions and drive investment and exports

✅ 30% energy target by 2030, backed by CfD support

✅ 250m industry investment and smart grid build-out

✅ Battery storage and interconnectors balance intermittency

 

Plans are afoot to make wind the UKs main power source for the first time in history amid ambitious targets to generate 30 percent of its total energy supply by 2030, up from 8 percent at present.

A recently inked deal will see the offshore wind industry invest 250 million into technology and infrastructure over the next 11 years, with the government committing up to 557 million in support, under a renewable energy auction that boosts wind and tidal projects, as part of its bid to lower carbon emissions to 80 percent of 1990 levels by 2050.

Offshore wind investment is crucial for meeting decarbonisation targets while increasing energy production, says Dominic Szanto, Director, Energy and Infrastructure at JLL. The governments approach over the last seven years has been to promise support to the industry, provided that cost reduction targets were met. This certainty has led to the development of larger, more efficient wind turbines which means the cost of offshore wind energy is a third of what it was in 2012.

 

Boosting the wind industry

Offshore wind power has been gathering pace in the UK and has grown despite COVID-19 disruptions in recent years. Earlier this year, the Hornsea One wind farm, the worlds largest offshore generator which is located off the Yorkshire coast, started producing electricity. When fully operational in 2020, the project will supply energy to over a million homes, and a further two phases are planned over the coming decade.

Over 10 gigawatts of offshore wind either already has government support or is eligible to apply for it in the near future, following a 10 GW contract award that underscores momentum, representing over 30 billion of likely investment opportunities.

Capital is coming from European utility firms and increasingly from Asian strategic investors looking to learn from the UKs experience. The attractive government support mechanism means banks are keen to lend into the sector, says Szanto.

New investment in the UKs offshore wind sector will also help to counter the growing influence of China. The UK is currently the worlds largest offshore wind market, but by 2021 it will be outstripped by China.

Through its new deal, the government hopes to increase wind power exports fivefold to 2.6 billion per year by 2030, with the UKs manufacturing and engineering skills driving projects in growth markets in Europe and Asia and in developing countries supported by the World Bank support through financing and advisory programs.

Over the next two decades, theres a massive opportunity for the UK to maintain its industry leading position by designing, constructing, operating and financing offshore wind projects, says Szanto. Building on projects such as the Hywind project in Scotland, it could become a major export to countries like the USA and Japan, where U.S. lessons from the U.K. are informing policy and coastal waters are much deeper.

 

Wind-powered smart grids

As wind power becomes a major contributor to the UKs energy supply, which will be increasingly made up of renewable sources in coming decades, there are key infrastructure challenges to overcome.

A real challenge is that the UKs power generation is becoming far more decentralised, with smaller power stations such as onshore wind farms and solar parks and more prosumers residential houses with rooftop solar coupled with a significant rise in intermittent generation, says Szanto. The grid was never designed to manage energy use like that.

One potential part of the solution is to use offshore wind farms in other sites in European waters.

By developing connections between wind projects from neighbouring countries, it will create super-grids that will help mitigate intermittency issues, says Szanto.

More advanced energy storage batteries will also be key for when less energy is generated on still days. There is a growing need for batteries that can store large amounts of energy and smart technology to discharge that energy. Were going through a revolution where new technology companies are working to enable a much smarter grid.

Future smart grids, based on developing technology such as blockchain, might enable the direct trading of energy between generators and consumers, with algorithms that can manage many localised sources and, critically, ensure a smooth power supply.

Investors seeking a higher-yield market are increasingly turning to battery technology, Szanto says. In a future smart grid, for example, batteries could store electricity bought cheaply at low-usage times then sold at peak usage prices or be used to provide backup energy services to other companies.

 

Majors investing in the transition

Its not just new energy technology companies driving change; established oil and gas companies are accelerating spending on renewable energy. Shell has committed to $1-2 billion per year on clean energy technologies out of a $25-30 billion budget, while Equinor plans to spend 15-20 percent of its budget on renewables by 2030.

The oil and gas majors have the global footprint to deliver offshore wind projects in every country, says Szanto. This could also create co-investment opportunities for other investors in the sector especially as nascent wind markets such as the U.S., where the U.S. offshore wind timeline is still developing, and Japan evolve.

European energy giants, for example, have bid to build New Yorks first offshore wind project.

As offshore wind becomes a globalised sector, with a trillion-dollar market outlook emerging, the major fuel companies will have increasingly large roles. They have the resources to undertake the years-long, cost-intensive developments of wind projects, driven by a need for new business models as the world looks beyond carbon-based fuels, says Szanto.

Oil and gas heavyweights are also making wind, solar and energy storage acquisitions BP acquired solar developer Lightsource and car-charging network Chargemaster, while Shell spent $400 million on solar and battery companies.

The public perception is that renewable energy is niche, but its now a mainstream form of energy generation., concludes Szanto.

Every nation in the world is aligned in wanting a decarbonised future. In terms of electricity, that means renewable energy and for offshore wind energy, the outlook is extremely positive.

Nevada on track to reach RPS mandate of 50% renewable electricity by 2030: report

Nevada Renewable Portfolio Standard 2030 targets 50% clean energy, advancing solar, geothermal, and wind, cutting GHG emissions, phasing out coal, and expanding storage, EV infrastructure, and in-state renewables under PUCN oversight and tax abatements.

 

Key Points

A state mandate requiring 50% of electricity from renewables by 2030, driving solar, geothermal, wind, and storage.

✅ 50% clean power by 2030; 100% carbon-free target by 2050

✅ Growth in solar, geothermal, wind; coal phase-out; natural gas remains

✅ RETA incentives spur 6.1 GW capacity, jobs, and in-state investment

 

Nevada is on track to meet its Renewable Portfolio Standard of 50% of electricity generated by renewable energy sources by 2030, according to the Governor's Office of Energy's annual Status of Energy Report.

Based on compliance reports the Public Utilities Commission of Nevada has received, across all providers, about 20% of power is currently generated by renewable resources, and, nationally, renewables ranked second in 2020 as filings show Nevada's investor-owned utility and other power providers have plans to reach the state's ambitious RPS of 50% by 2030, according to the report released Jan. 28.

"Because transportation and electricity generation are Nevada's two largest contributors to greenhouse gas emissions, GOE's program work in 2021 underscored our focus on transportation electrification and reaching the state's legislatively required renewable portfolio standard," GOE Director David Bobzien said in a statement Jan. 28. "While electricity generated from renewable resources currently accounts for about 25% of the state's electricity, a share similar to projections that renewables will soon provide about one-fourth of U.S. electricity overall, we continue to collaborate with the Public Utilities Commission of Nevada, electricity providers, the renewable energy industry and conservation organizations to ensure Nevada reaches our target of 50% clean energy by 2030."

The state's RPS, enacted in 1997 and last modified in 2019, requires an increase in renewable energy, starting with 22% in 2020 and increasing to 50% by 2030. The increase in renewables will reduce GHG emissions and help the state reach its goal of 100% carbon-free power by 2050, while states like Rhode Island have a 100% by 2030 plan, highlighting varying timelines.

Renewable additions
The state added 1.332 GW of renewable capacity in 2021 as part of the Renewable Energy Tax Abatement program, at a time when U.S. renewable energy hit a record 28% in April, for a total renewable capacity of 6.117 GW, according to the report.

The RETA program awards partial sales and use tax and partial property-tax abatements to eligible renewable energy facilities, which increase Nevada's tax revenue and create jobs in a growing industry. Eligible projects must employ at least 50% Nevada workers, pay 175% of Nevada's average wage during construction, and offer health care benefits to workers and their dependents.

Since its adoption in 2010, the GOE has approved 60 projects, including large-scale solar PV, solar thermal, biomass, geothermal and wind projects throughout the state, according to the report. Projects granted abatements in 2021 include:

  • 100-MW Citadel Solar Project
  • 150-MW Dry Lake Solar + Storage Project
  • 714-MW Gemini Solar Project
  • 55-MW North Valley Power Geothermal Project
  • 113-MW Boulder Flats Solar Project
  • 200-MW Arrow Canyon Solar Project

"Nevada does not produce fossil fuels of any significant amount, and gasoline, jet fuel and natural gas for electricity or direct use must be imported," according to the report. "Transitioning to domestically produced renewable resources and electrified transportation can provide cost savings to Nevada residents and businesses, as seen in Idaho's largely renewable mix today, while reducing GHG emissions. About 86% of the fuel for energy that Nevada consumes comes from outside the state."

Phasing out coal plants
Currently, more than two-thirds of the state's electricity is produced by natural gas-fired power plants, with renewables covering most of the remaining generation, according to the report. Nevada continues to phase out its remaining coal power plants, as renewables surpassed coal nationwide in 2022, which provide less than 10% of produced electricity.

"Nevada has seen a significant increase in capturing its abundant renewable energy resources such as solar and geothermal," according to the report. "Renewable energy production continues to grow, powering Nevada homes and business and serves to diversify the state's economy by exporting solar and geothermal to neighboring states, as California neared 100% renewable electricity for the first time. Nevada has more than tripled its renewable energy production since 2011."

Federal net-zero electricity regulations will permit some natural gas power generation

Canada Clean Electricity Regulations allow flexible, technology-neutral pathways to a 2035 net-zero grid, permitting limited natural gas with carbon capture, strict emissions standards, and exemptions for emergencies and peak demand across provinces and territories.

 

Key Points

Federal draft rules for a 2035 net-zero grid, allowing limited gas with CCS under strict performance and compliance standards.

✅ Performance cap: 30 tCO2 per GWh annually for gas plants

✅ CCS must sequester 95% of emissions to comply

✅ Emergency and peak demand exemptions permitted

 

After facing pushback from Alberta and Saskatchewan, and amid looming power challenges nationwide, Canada's draft net-zero electricity regulations — released today — will permit some natural gas power generation. 

Environment Minister Steven Guilbeault released Ottawa's proposed Clean Electricity Regulations on Thursday.

Provinces and territories will have a minimum 75-day window to comment on the draft regulations. The final rules are intended to pave the way to a net-zero power grid in Canada, aligning with 2035 clean electricity goals established nationally. 

Calling the regulations "technology neutral," Guilbeault said the federal government believes there's enough flexibility to accommodate the different energy needs of Canada's diverse provinces and territories, including how Ontario is embracing clean power in its planning. 

"What we're talking about is not a fossil fuel-free grid by 2035; it's a net zero grid by 2035," Guilbeault said. 

"We understand there will be some fossil fuels remaining … but we're working to minimize those, and the fossil fuels that will be used in 2035 will have to comply with rigorous environmental and emission standards," he added. 

Some analysts argue that scrapping coal-fired electricity can be costly and ineffective, underscoring the trade-offs in transition planning.

While non-emitting sources of electricity — hydroelectricity, wind and solar and nuclear — should not have any issues complying with the regulations, natural gas plants will have to meet specific criteria.

Those operations, the government said, will need to emit the equivalent of 30 tonnes of carbon dioxide per gigawatt hour or less annually to help balance demand and emissions across the grid.

Federal officials said existing natural gas power plants could comply with that performance standard with the help of carbon capture and storage systems, which would be required to sequester 95 per cent of their emissions.

"In other words, it's achievable, and it is achievable by existing technology," said a government official speaking to reporters Thursday on background and not for attribution.

The regulations will also allow a certain level of natural gas power production without the need to capture emissions. Capturing emissions will be exempted during emergencies and peak periods when renewables cannot keep up with demand. 

Some newer plants might not have to comply with the rules until the 2040s, because the regulations apply to plants 20 years after they are commissioned, which dovetails with net-zero by 2050 commitments from electricity associations. 

The two-decade grace period does not apply to plants that open after the regulations are expected to be finalized in 2025.

Sudbury Hydro crews aim to reconnect service after storm

Sudbury Microburst Power Outage strains hydro crews after straight-line winds; New Sudbury faces downed power lines, tree damage, and hazardous access as restoration efforts, mutual aid, and safety protocols aim to reconnect customers by weekend.

 

Key Points

A microburst downed lines in New Sudbury, cutting power as crews tackle hazardous access and complex repairs.

✅ Straight-line winds downed poles, trees, and service lines

✅ Crews face backyard access hazards, complex reconnections

✅ Mutual aid linemen, arborists, and crane work speed restoration

 

About 300 Sudbury Hydro customers are still without power Thursday after Monday's powerful microburst storm, part of a series of damaging storms in Ontario seen across the province.

The utility's spokesperson, Wendy Watson, says the power in the affected New Sudbury neighbourhoods should be back on by the weekend, even as Toronto power outages persisted in a recent storm.

The storm, which Environment Canada said was classified as a microburst or straight line wind damage, similar to a severe windstorm in Quebec, downed a number of power lines in the city.

Now crews are struggling with access to the lines, a challenge that BC Hydro's atypical storm response also highlighted, as they work to reconnect service in the area.

"In some cases, you can't get to someone's back yard, or you have to go through the neighbour's yard," Watson said.

"We have one case where [we had] equipment working over a swimming pool. It's dicey, it's really dirty and it's dangerous."

Veteran arborist Jim Allsop told CBC News he hasn't seen damage like this in his 30-plus years in the business.

"I don't know how many we've done up to date, but I have another 35 trees on houses," Allsop said. "We'll be probably another week."

"We've rented a crane to help speed up the process, and increase safety, and we're getting five or six done in our 12-hour days."

Scott Aultman, a lineman with North Bay Hydro, said he has seen a few storms in his career, and isn't usually surprised by extensive damage a storm can cause.

"When you see a trailer on its side, you know, you don't see that every day," Aultman said.

But during the clean up, Aultman said the spirit of camaraderie runs high with crews from different areas, as seen when Canadian crews helped Florida during Hurricane Irma.

"We were pumped. It's part of the trade, everybody gets together," Aultman said. "We had a big storm in 2006 and the Sudbury guys were up helping us, so it's great, it's nice to be able to return the favour and help them out."

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

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

 

Key Points

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

✅ Power line failed between poles, arcing ignited vegetation.

✅ 696 acres burned; no structures damaged or injuries.

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

 

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

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

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

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

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

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

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

Canadian Scientists say power utilities need to adapt to climate change

Canada Power Grid Climate Resilience integrates extreme weather planning, microgrids, battery storage, renewable energy, vegetation management, and undergrounding to reduce outages, harden infrastructure, modernize utilities, and safeguard reliability during storms, ice events, and wildfires.

 

Key Points

Canada's grid resilience hardens utilities against extreme weather using microgrids, storage, renewables, and upgrades.

✅ Grid hardening: microgrids, storage, renewable integration

✅ Vegetation management reduces storm-related line contact

✅ Selective undergrounding where risk and cost justify

 

The increasing intensity of storms that lead to massive power outages highlights the need for Canada’s electrical utilities to be more robust and innovative, climate change scientists say.

“We need to plan to be more resilient in the face of the increasing chances of these events occurring,” University of New Brunswick climate change scientist Louise Comeau said in a recent interview.

The East Coast was walloped this week by the third storm in as many days, with high winds toppling trees and even part of a Halifax church steeple, underscoring the value of storm-season electrical safety tips for residents.

Significant weather events have consistently increased over the last five years, according to the Canadian Electricity Association (CEA), which has tracked such events since 2003.

#google#

Nearly a quarter of total outage hours nationally in 2016 – 22 per cent – were caused by two ice storms, a lightning storm, and the Fort McMurray fires, which the CEA said may or may not be classified as a climate event.

“It (climate change) is putting quite a lot of pressure on electricity companies coast to coast to coast to improve their processes and look for ways to strengthen their systems in the face of this evolving threat,” said Devin McCarthy, vice president of public affairs and U.S. policy for the CEA, which represents 40 utilities serving 14 million customers.

The 2016 figures – the most recent available – indicate the average Canadian customer experienced 3.1 outages and 5.66 hours of outage time.

McCarthy said electricity companies can’t just build their systems to withstand the worst storm they’d dealt with over the previous 30 years. They must prepare for worse, and address risks highlighted by Site C dam stability concerns as part of long-term planning.

“There needs to be a more forward looking approach, climate science led, that looks at what do we expect our system to be up against in the next 20, 30 or 50 years,” he said.

Toronto Hydro is either looking at or installing equipment with extreme weather in mind, Elias Lyberogiannis, the utility’s general manager of engineering, said in an email.

That includes stainless steel transformers that are more resistant to corrosion, and breakaway links for overhead service connections, which allow service wires to safely disconnect from poles and prevents damage to service masts.

Comeau said smaller grids, tied to electrical systems operated by larger utilities, often utilize renewable energy sources such as solar and wind as well as battery storage technology to power collections of buildings, homes, schools and hospitals.

“Capacity to do that means we are less vulnerable when the central systems break down,” Comeau said.

Nova Scotia Power recently announced an “intelligent feeder” pilot project, which involves the installation of Tesla Powerwall storage batteries in 10 homes in Elmsdale, N.S., and a large grid-sized battery at the local substation. The batteries are connected to an electrical line powered in part by nearby wind turbines.

The idea is to test the capability of providing customers with back-up power, while collecting data that will be useful for planning future energy needs.

Tony O’Hara, NB Power’s vice-president of engineering, said the utility, which recently sounded an alarm on copper theft, was in the late planning stages of a micro-grid for the western part of the province, and is also studying the use of large battery storage banks.

“Those things are coming, that will be an evolution over time for sure,” said O’Hara.

Some solutions may be simpler. Smaller utilities, like Nova Scotia Power, are focusing on strengthening overhead systems, mainly through vegetation management, while in Ontario, Hydro One and Alectra are making major investments to strengthen infrastructure in the Hamilton area.

“The number one cause of outages during storms, particularly those with high winds and heavy snow, is trees making contact with power lines,” said N.S. Power’s Tiffany Chase.

The company has an annual budget of $20 million for tree trimming and removal.

“But the reality is with overhead infrastructure, trees are going to cause damage no matter how robust the infrastructure is,” said Matt Drover, the utility’s director for regional operations.

“We are looking at things like battery storage and a variety of other reliability programs to help with that.”

NB Power also has an increased emphasis on tree trimming and removal, and now spends $14 million a year on it, up from $6 million prior to 2014.

O’Hara said the vegetation program has helped drive the average duration of power outages down since 2014 from about three hours to two hours and 45 minutes.

Some power cables are buried in both Nova Scotia and New Brunswick, mostly in urban areas. But both utilities maintain it’s too expensive to bury entire systems – estimated at $1 million per kilometre by Nova Scotia Power.

The issue of burying more lines was top of mind in Toronto following a 2013 ice storm, but that’s city’s utility also rejected the idea of a large-scale underground system as too expensive – estimating the cost at around $15 billion, while Ontario customers have seen Hydro One delivery rates rise in recent adjustments.

“Having said that, it is prudent to do so for some installations depending on site specific conditions and the risks that exist,” Lyberogiannis said.

Comeau said lowering risks will both save money and disruption to people’s lives.

“We can’t just do what we used to do,” said Xuebin Zhang, a senior climate change scientist at Environment and Climate Change Canada.

“We have to build in management risk … this has to be a new norm.”
