Global Energy Interconnection enables cross-border grids to share renewables, enhance reliability, and cut emissions through IEC standards, smart transmission, and policy coordination, advancing sustainable energy access, decarbonization, and climate resilience worldwide.

 

Key Points

A worldwide grid concept to share renewables, boost dependability, and expand clean energy access.

✅ Harmonizes international standards for ultra-high-voltage transmission

✅ Enhances grid dependability and cross-border renewable integration

✅ Requires global policy, market, and stakeholder coordination

 

Energy is central to nearly every major challenge and opportunity the world faces. However, one fifth of the world population still lacks access to energy and 3 billion people rely on wood, coal or animal waste for cooking and heating. Today, sustainable energy and grid climate risks are big global concerns.

The interconnection of grids as seen in Texas grid connection efforts would open up an unprecedented opportunity to globally share the resources of the whole planet, bringing clean energy to everybody, everywhere in the world.

Global Energy Interconnection

Global energy interconnection (GEI) is technically highly complex, with enablers like HVDC technology in play. It will require a level of dependability never seen before. International Standards inherently contain solutions that will help pre-address this complexity and they will play a crucial role in mastering dependability upfront.

This White Paper aims to assess the worldwide needs, benefits, policies and preconditions for GEI. It examines the readiness of potential markets and identifies technical and business trends such as the digital grid as well as hurdles. The White Paper analyzes and compares several global transmission scenarios and evaluates their impact on energy supply, the environment, technologies, and policies, as well as standards development.

Last but not least, this White Paper will provide recommendations on how standardization for such a large system of systems will need to be conducted and which stakeholders have to be involved.

Dr. Hu Hao, Senior Project Manager, International Cooperation Department, State Grid Corporation of China, states “To achieve the ambitious concept of global energy interconnection (GEI) or large scale, regional, intercontinental interconnection, requires political vision and a worldwide collaborative effort. Drawing up GEI concepts at an early stage by a consensus based process and through close cooperation between researchers, industry, regulators and standardization bodies is one of the central requirements for success of the implementation of the concept.”

This White Paper was developed by the IEC Market Strategy Board with major contributions from the International Energy Agency and State Grid Corporation of China, aligning with initiatives to build a smarter electricity infrastructure globally.

The gloves are off - Alberta suspends electricity purchase talks with B.C.

Alberta-BC Pipeline Dispute centers on Trans Mountain expansion, diluted bitumen shipments, federal approval, spill response capacity, and electricity trade, as Alberta suspends power talks and Ottawa insists the Kinder Morgan project proceeds in national interest.

 

Key Points

Dispute over Trans Mountain expansion, bitumen limits, and jurisdiction between Alberta, B.C., and Canada.

✅ Alberta suspends BC electricity talks as leverage

✅ Ottawa affirms federal approval and spill response

✅ BC plans advisory panel on diluted bitumen risks

 

Alberta Premier Rachel Notley says her government is suspending talks with British Columbia on the purchase of electricity from the western province.

It’s the first step in Alberta’s fight against the B.C. government’s proposal to obstruct the Kinder Morgan oil pipeline expansion project by banning increased shipments of diluted bitumen to the province’s coast.

Up to $500 million annually for B.C.’s coffers from electricity exports hangs in the balance, Notley said.

“We’re prepared to do what it takes to get this pipeline built — whatever it takes,” she told a news conference Thursday after speaking with Prime Minister Justin Trudeau on the phone.

Notley said she told Trudeau, who’s in Edmonton for a town-hall meeting, that the federal government needs to act decisively to end the dispute.

Speaking on Edmonton talk radio station CHED earlier in the day, Trudeau said the pipeline expansion is in the national interest and will go ahead, even as the federal government undertakes a study on electrification across sectors.

“That pipeline is going to get built,” Trudeau said. “We will stand by our decision. We will ensure that the Kinder Morgan pipeline gets built.”

B.C.’s environment minister has said his minority government plans to ban increased shipments until it can determine that shippers are prepared and able to properly clean up a spill, and, separately, has implemented an electricity rate freeze affecting consumers. He said he will establish an independent scientific advisory panel to study the issue.

The move infuriated Notley, who has accused B.C. of trying to change the rules after the federal government gave the project the green light. B.C. has the right to regulate how any spills would be cleaned up, but can’t dictate what flows through pipelines, she said.

Trudeau said Canada needs to get Alberta’s oil safely to markets other than the U.S. energy market today. He said the federal government did the research and has spent billions on spill response.

“The Kinder Morgan pipeline is not a danger to the B.C. coast,” he said.

Notley said she thanked Trudeau for his assurance that the project will go ahead, but the federal government has to do more to ensure the pipeline’s expansion.

“This is not an Alberta-B.C. issue. This is a Canada-B.C. issue,” she said. “This kind of uncertainty is bad for investment and bad for working people

“Enough is enough. We need to get these things built.”

B.C. Premier John Horgan said his government consulted Alberta and Ottawa about his province’s intentions, noting that Columbia River Treaty talks also shape regional electricity policy.

“I don’t see what the problem is,” Horgan said Thursday at a school opening north of Kelowna, B.C. “It’s within our jurisdiction to put in place regulations to protect the public interest.

“That’s what we are doing.”

He downplayed any possibility of court action or sanctions by Alberta.

“There’s nothing to take to court,” Horgan said. “We are consulting with the people of B.C. It’s way too premature to talk about those sorts of issues.

“Sabre-rattling doesn’t get you very far.”

Speaking in Ottawa, Natural Resources Minister Jim Carr wouldn’t say what Canada might do if British Columbia implements its regulation.

“That’s speculative,” said Carr.

He noted at this point, B.C. has just pledged to consult. He said the federal government heard from thousands of people before the pipeline was approved.

“That’s what they have announced — an intention to consult. We have already consulted.”

B.C.’s proposal creates more uncertainty for Kinder Morgan’s already-delayed Trans Mountain expansion project that would nearly triple the capacity of its pipeline system to 890,000 barrels a day.

Energy dashboard: how is electricity generated in Great Britain?

Great Britain electricity generation spans renewables and baseload: wind, solar, nuclear, gas, and biomass, supported by National Grid interconnectors, embedded energy estimates, and BMRS data for dynamic imports and exports across Europe.

 

Key Points

A diverse, weather-driven mix of renewables, gas, nuclear, and imports coordinated by National Grid.

✅ Baseload from nuclear and biomass; intermittent wind and solar

✅ Interconnectors trade zero carbon imports via subsea cables

✅ Data from BMRS and ESO covers embedded energy estimates

 

Great Britain has one of the most diverse ranges of electricity generation in Europe, with everything from windfarms off the coast of Scotland to a nuclear power station in Suffolk tasked with keeping the lights on. The increasing reliance on renewable energy sources, as part of the country’s green ambitions, also means there can be rapid shifts in the main source of electricity generation. On windy days, most electricity generation comes from record wind generation across onshore and offshore windfarms. When conditions are cold and still, gas-fired power stations known as peaking plants are called into action.

The electricity system in Great Britain relies on a combination of “baseload” power – from stable generators such as nuclear and biomass plants – and “intermittent” sources, such as wind and solar farms that need the right weather conditions to feed energy into the grid. National Grid also imports energy from overseas, through subsea cables known as interconnectors that link to France, Belgium, Norway and the Netherlands. They allow companies to trade excess power, such as renewable energy created by the sun, wind and water, between different countries. By 2030 it is hoped that 90% of the energy imported by interconnectors will be from zero carbon energy sources, though low-carbon electricity generation stalled in 2019 for the UK.

The technology behind Great Britain’s power generation has evolved significantly over the last century, and at times wind has been the main source of electricity. The first integrated national grid in the world was formed in 1935 linking seven regions of the UK. In the aftermath of industrialisation, coal provided the vast majority of power, before oil began to play an increasingly important part in the 1950s. In 1956, the world’s first commercial nuclear reactor, Calder Hall 1 at Windscale (later Sellafield), was opened by Queen Elizabeth II. Coal use fell significantly in the 1990s while the use of combined cycle gas turbines grew, and in 2016 wind generated more electricity than coal for the first time. Now a combination of gas, wind, nuclear and biomass provide the bulk of Great Britain’s energy, with smaller sources such as solar and hydroelectric power also used. From October 2024, coal will no longer be used to generate electricity, following coal-free power records set in recent years.

Energy generation data is fetched from the Balancing Mechanism Reporting Service public feed, provided by Elexon – which runs the wholesale energy market – and is updated every five minutes, covering periods when wind led the power mix as well.

Elexon’s data does not include embedded energy, which is unmetered and therefore invisible to Great Britain’s National Grid. Embedded energy comprises all solar energy and wind energy generated from non-metered turbines. To account for these figures we use embedded energy estimates from the National Grid electricity system operator, which are published every 30 minutes.

Import figures refer to the net flow of electricity from the interconnectors with Europe and with Northern Ireland. A positive value represents import into the GB transmission system, while a negative value represents an export.

Hydro figures combine renewable run-of-the-river hydropower and pumped storage.

Biomass figures include Elexon’s “other” category, which comprises coal-to-biomass conversions and biomass combined heat and power plants.

China boosts wind energy, photovoltaic and concentrated solar power

China Renewable Energy Law drives growth in wind power, solar thermal, and photovoltaic capacity, supporting grid integration and five-year plans, even as China leads CO2 emissions, with policy incentives, compliance inspections, and national resource assessments.

 

Key Points

A legal framework that speeds wind, solar thermal, and PV growth in China via mandates, incentives, and grid rules.

✅ 2018 renewables: 1.87T kWh, 26.7% of national power

✅ Over 100 State Council policies enabling deployment

✅ Law inspections and regional oversight across six provinces

 

China leads renewable energies, installing more wind power, solar thermal and photovoltaic than any other country, as seen in the China solar PV growth reported in 2016, but also leads CO2 emissions, and much remains to be done.

The effective application of Chinas renewable energy law has boosted the use of renewable energy in the country and facilitated the rapid development of the sector, as solar parity across Chinese cities indicates, a report said.

The report on compliance with renewable energy law was presented today at the current bimonthly session of the Standing Committee of the National Peoples Assembly (APN).

Electricity generated by renewable energy amounted to about 1.87 trillion kilowatts per hour in 2018, representing 26.7 percent of Chinas total energy production in the year, aligning with trends where wind and solar doubling globally over five years, the report said.

Ding Zhongli, vice president of the NPC Standing Committee, presented the report to the legislators at the second plenary meeting of the session.

An inspection of the law enforcement was carried out from August to November, as U.S. renewables hit 28% record showed momentum elsewhere. A total of 21 members of the NPC Standing Committee and the NPC Environmental Protection and Resource Conservation Committee, as well as national legislators, traveled to six regions at the provincial level on inspection visits. Twelve legislative bodies at the provincial level inspected the law enforcement efforts in their jurisdictions.

The relevant State Council agencies have implemented more than 100 regulations and policies to foster a good policy environment for the development of renewable energy, as seen in markets where U.S. renewable electricity surpassed coal in 2022. Local regulations have also been formulated based on local conditions, according to the report.

In accordance with the law, a thorough investigation of the national conditions of renewable energy resources was undertaken.

In 2008 and 2014 atlas of solar energy resources and wind energy evaluation of China were issued. The relevant agencies of the State Council have also implemented five-year plans for the development of renewable energy, which have provided guidance to the sector, while countries like Ireland's one-third green power target remain in focus within four years.

The main provisions of the law have been met, the law has been effectively applied and the purpose of the legislation has been met, and this momentum is echoed abroad, with U.S. renewables near one-fourth according to projections, Ding said.

Two new electricity interconnectors planned for UK

Ofgem UK Electricity Interconnectors will channel subsea cables, linking Europe, enabling energy import/export, integrating offshore wind via multiple-purpose interconnectors, boosting grid stability, capacity, and investment under National Grid analysis to 2030 targets.

 

Key Points

Subsea links between the UK and Europe that trade power, integrate offshore wind, and reinforce grid capacity.

✅ Two new subsea interconnector bids open in 2025

✅ Pilot for multiple-purpose links to offshore wind clusters

✅ National Grid to assess optimal routes, capacity, and locations

 

Ofgem has opened bids to build two electricity interconnectors between the UK and continental Europe as part of the broader UK grid transformation now underway.

The energy regulator said this would “bring forward billions of pounds of investment” in the subsea cables, such as the Lake Erie Connector, which can import cheaper energy when needed and export surplus power from the UK when it is available.

Developers will be invited to submit bids to build the interconnectors next year. Ofgem will additionally run a pilot scheme for ‘multiple-purpose interconnectors’, which are used to link clusters of offshore wind farms and related innovations like an offshore vessel chargepoint to an interconnector.

This forms part of the UK Government drive to more than double capacity by 2030, and to manage rising electric-vehicle demand, as discussed in EV grid impacts, in support of its target of quadrupling offshore wind capacity by the same date.

Interconnectors provide some 7 per cent of UK electricity demand. The UK so far has seven electricity interconnectors linked to Ireland, France, Belgium, the Netherlands and Norway, while projects like the Ireland-France connection illustrate broader European grid integration.

Balfour Beatty won a £90m contract for onshore civil engineering works on the Viking Link Norway interconnector, which is due to come into operation in 2023, while London Gateway's all-electric berth highlights related port electrification.

It said that interconnector developers have in the past been allowed to propose their preferred design, connection location and sea route to the connecting country. Ofgem has now said it may decide to consider only those projects that meet its requirements based on an analysis of location and capacity needs by National Grid.

Ofgem has not specified that the new interconnectors must link to any specific place or country, but may do so later, as priorities like the Cyprus electricity highway illustrate emerging directions.

Maritime Link almost a reality, as first power cable reaches Nova Scotia

Maritime Link Subsea Cable enables HVDC grid interconnection across the Cabot Strait, linking Nova Scotia with Newfoundland and Labrador to import Muskrat Falls hydroelectric power and expand renewable energy integration and reliability.

 

Key Points

A 170-km HVDC subsea link connecting Nova Scotia and Newfoundland and Labrador for Muskrat Falls power and renewables

✅ 170-km HVDC subsea route across Cabot Strait

✅ Connects Nova Scotia and Newfoundland and Labrador grids

✅ Enables Muskrat Falls hydro and renewable energy trade

 

The longest sub-sea electricity cable in North America now connects Nova Scotia and Newfoundland and Labrador, according to the company behind the $1.7-billion Maritime Link project.  

The first of the project's two high-voltage power transmission cables was anchored at Point Aconi, N.S., on Sunday. 

The 170-kilometre long cable across the Cabot Strait will connect the power grids in the two provinces. The link will allow power to flow between the two provinces, as demonstrated by its first electricity transfer milestone, and bring to Nova Scotia electricity generated by the massive Muskrat Falls hydroelectric project in Labrador. 

Ultimately, the Maritime Link will help Nova Scotia reach the renewable energy goals set out by the federal government, said Rick Janega, the president and CEO of Emera Newfoundland and Labrador, whose subsidiary owns the Maritime Link.

"If not for the Maritime Link then really the province would not have the ability to meet those requirements because we're pretty much tapped out of all the hydro in province and all the wind generation without creating new interconnections like the Maritime Link," said Janega. 

Not everyone wanted the link 

Fishermen in Cape Breton had objected to the Maritime Link. They were concerned about how the undersea cable might affect fish in the area. 

The laying of the cable and other construction closed a three-kilometre long and 600-metre wide swath of ocean bottom to fishermen for the entire 2017 lobster season.  

But the company came to an agreement to compensate a group of 60 Cape Breton lobster and crab fishermen affected by the project this season. The terms of the compensation deal were not released. 

 

Long cable, big job

The transmission cable runs northwest of the Marine Atlantic ferry route between North Sydney, N.S., and Port aux Basques, N.L. 

Installation of the second cable is set to begin in June, a major step comparable to BC Hydro's Site C transmission milestone achieved recently. The entire link should be completed by late 2017 and should go into full service by January 2018.

"We're quite confident as soon as the Maritime Link is in service there will be energy transactions between Nova Scotia Power and Newfoundland Hydro. Both utilities have already identified opportunities to save money and exchange energy between the two provinces," said Janega.

That's two years before power is expected to flow from the Muskrat Falls hydro project. The Labrador-based power generating facility has been hampered by delays.

Those kinds of transmission project delays are expected for such a large project, said Janega, and won't stop the Maritime Link from being used. 

"With the Maritime Link going in service this year providing Nova Scotia the opportunity that it needs to be able to reach carbon reductions and to adapt to climate change and to increase renewable energy content and we're very pleased to be at this state today," said Janega.
