Britain Electricity Demand During Lockdown is around 10 percent lower, as industrial consumers scale back. National Grid reports later morning peaks and continues balancing system frequency and voltage to maintain grid stability.

Key Points

Measured drop in UK power use, later morning peaks, and grid actions to keep frequency and voltage within safe limits.

✅ Daily demand about 10 percent lower since lockdown.

✅ Morning peak down nearly 18 percent and occurs later.

✅ National Grid balances frequency and voltage using flexible resources.

Daily electricity demand in Britain is around 10% lower than before the country went into lockdown last week due to the coronavirus outbreak, data from grid operator National Grid showed on Tuesday.

The fall is largely due to big industrial consumers using less power across sectors, the operator said.

Last week, Prime Minister Boris Johnson ordered Britons to stay at home to halt the spread of the virus, imposing curbs on everyday life without precedent in peacetime.

Morning peak demand has fallen by nearly 18% compared to before the lockdown was introduced and the normal morning peak is later than usual because the times people are getting up are later and more spread out with fewer travelling to work and school, a pattern also seen in Ottawa during closures, National Grid said.

Even though less power is needed overall, the operator still has to manage lower demand for electricity, as well as peaks, amid occasional short supply warnings from National Grid, and keep the frequency and voltage of the system at safe levels.

Last August, a blackout cut power to one million customers and caused transport chaos as almost simultaneous loss of output from two generators caused by a lightning strike caused the frequency of the system to drop below normal levels, highlighting concerns after the emergency energy plan stalled.

National Grid said it can use a number of tools to manage the frequency, such as working with flexible generators to reduce output or draw on storage providers to increase demand, and market conditions mean peak power prices have spiked at times.

Amazon Renewable Energy Projects advance net zero goals with a Scotland wind farm PPA and US solar farms in North Carolina and Virginia, delivering clean power, added capacity, and lower carbon emissions across cloud operations.

Key Points

Amazon initiatives adding wind and solar capacity in the UK and US to cut carbon and power cloud operations.

✅ Largest UK corporate wind PPA on Scotland Kintyre Peninsula

✅ Two US solar farms in North Carolina and Virginia

✅ 265 MW added capacity, 668,997 MWh clean power annually

Amazon is launching three renewable energy projects in the United States and the United Kingdom that support Amazon’s commitment to using net zero carbon energy by 2040.

The U.K. project is a wind farm on the Kintyre Peninsula in Scotland, aligned with a 10 GW renewables contract boosting the U.K. grid. It will generate 168,000 megawatt hours (MWh) of clean energy each year, enough to power 46,000 U.K. homes. It will be the largest corporate wind power purchase agreement (PPA) in the U.K.

Offshore wind energy in the UK is powering up rapidly, complementing onshore developments.

The other two are solar projects – one in Warren County, N.C, and the other in Prince George County, Va, reflecting broader US solar and wind growth trends nationwide. Together, they are expected to generate 500,997 MWh of energy annually. It is Amazon’s second renewable energy project in North Carolina, following the Amazon Wind Farm US East operated by Avangrid Renewables, and eighth in Virginia.

The three new Amazon wind and solar projects – which are expected to be in operation in 2012 — will provide 265 MW of additional renewable capacity, and align with U.K. wind power lessons for the U.S. market nationwide.

“In addition to the environmental benefits inherently associated with running applications in the cloud, Amazon is committed to minimizing our carbon emissions and reaching 80% renewable energy use across the company by 2024. We’ve announced eight projects this year and have more projects on the horizon – and we’re committed to investing in renewable energy as a critical step toward addressing our carbon footprint globally,” Kara Hurst, director of sustainability at Amazon, said. “With nearly 70 renewable energy projects around the globe – including 54 solar rooftops – we are making significant progress towards reaching Amazon’s company-wide commitment to reach 100% renewable energy by 2030.”

Amazon has launched 18 utility-scale wind and solar renewable energy projects to date, and in parallel, Duke Energy Renewables has acquired three California solar projects, underscoring sector momentum. They will generate over 1,600 MW of renewable capacity and deliver more than 4.6 million MWh of clean energy annually. Amazon has also installed more than 50 solar rooftops on fulfillment centers and sort centers around the world. They generate 98 MW of renewable capacity and deliver 130,000 MWh of clean energy annually.

“Today’s announcement by Amazon is another important step for North Carolina’s clean energy plan that will increase our reliance on renewables and reduce our greenhouse gas emissions,” North Carolina Governor Roy Cooper said. “Not only is this the right thing to do for our planet, it’s the right thing to do for our economy. More clean energy jobs means better jobs for North Carolina families.”

Amazon reports on its sustainability commitments, initiatives, and performance on a new web site the company recently launched. It includes information on Amazon’s carbon footprint and other metrics and updates the company’s progress towards reaching The Climate Pledge. 

“It’s wonderful to see the announcement of these new projects, helping bring more clean energy to the Commonwealth of Virginia where Amazon is already recognized as a leader in bringing renewable energy projects online,” Virginia Governor Ralph Northam said. “These solar farms help reaffirm the Commonwealth’s role as a leading producer of clean energy in the U.S., helping take the nation forward in responding to climate change.”

Siemens Gamesa SG 14-222 DD advances offshore wind with a 14 MW direct-drive turbine, 108 m blades, a 222 m rotor, optional 15 MW boost, powering about 18,000 homes; prototype 2021, commercial launch 2024.

Key Points

A 14 MW offshore wind turbine with 108 m blades and a 222 m rotor, upgradable to 15 MW, targeting commercial use in 2024.

✅ 14 MW direct-drive, upgradable to 15 MW

✅ 108 m blades, 222 m rotor diameter

✅ Powers about 18,000 European homes annually

Siemens Gamesa Renewable Energy (SGRE) has released details of a 14-megawatt (MW) offshore wind turbine, as offshore green hydrogen production gains attention, in the latest example of how technology in the sector is increasing in scale.

With 108-meter-long blades and a rotor diameter of 222 meters, the dimensions of the SG 14-222 DD turbine are significant.

In a statement Tuesday, SGRE said that one turbine would be able to power roughly 18,000 average European households annually, while its capacity can also be boosted to 15 MW if needed. A prototype of the turbine is set to be ready by 2021, and it’s expected to be commercially available in 2024, as forecasts suggest a $1 trillion business this decade.

As technology has developed over the last few years, the size of wind turbines has increased, and renewables are set to shatter records globally.

Last December, for example, Dutch utility Eneco started to purchase power produced by the prototype of GE Renewable Energy’s Haliade-X 12 MW wind turbine. That turbine has a capacity of 12 MW, a height of 260 meters and a blade length of 107 meters.

The announcement of Siemens Gamesa’s new turbine plans comes against the backdrop of the coronavirus pandemic, which is impacting renewable energy companies around the world, even as wind power sees growth despite Covid-19 in many markets.

Earlier this month, the European company said Covid-19 had a “direct negative impact” of 56 million euros ($61 million) on its profitability between January and March, amid factory closures in Spain and supply chain disruptions. This, it added, was equivalent to 2.5% of revenues during the quarter.

The pandemic has, in some parts of the world, altered the sources used to power society. At the end of April, for instance, it was announced that a new record had been set for coal-free electricity generation in Great Britain, where UK offshore wind growth has accelerated, with a combination of factors — including coronavirus-related lockdown measures — playing a role.

On Tuesday, the CEO of another major wind turbine manufacturer, Danish firm Vestas, sought to emphasize the importance of renewable energy in the years and months ahead, and the lessons the U.S. can learn from the U.K. on wind deployment.

“I think we have actually, throughout this crisis, also shown to all society that renewables can be trusted,” Henrik Andersen said during an interview on CNBC’s Street Signs.

“But we both know ... that that transformation of energy sources is not going to happen overnight, it’s not going to happen from a quarter to a quarter, it’s going to happen by consistently planning year in, year out.”

Bitcoin energy consumption is driven by mining electricity demand, with TWh-scale power use, carbon footprint concerns, and Cambridge estimates. Rising prices incentivize more hardware; efficiency gains and renewables adoption shape sustainability outcomes.

Key Points

Bitcoin energy consumption is mining's electricity use, driven by price, device efficiency, and energy mix.

✅ Cambridge tool estimates ~121 TWh annual usage

✅ Rising BTC price incentivizes more mining hardware

✅ Efficiency, renewables, and costs shape footprint

"Mining" for the cryptocurrency is power-hungry, with power curtailments reported during heat waves, involving heavy computer calculations to verify transactions.

Cambridge researchers say it consumes around 121.36 terawatt-hours (TWh) a year - and is unlikely to fall unless the value of the currency slumps, even as Americans use less electricity overall.

Critics say electric-car firm Tesla's decision to invest heavily in Bitcoin undermines its environmental image.

The currency's value hit a record $48,000 (£34,820) this week. following Tesla's announcement that it had bought about $1.5bn bitcoin and planned to accept it as payment in future.

But the rising price offers even more incentive to Bitcoin miners to run more and more machines.

And as the price increases, so does the energy consumption, according to Michel Rauchs, researcher at The Cambridge Centre for Alternative Finance, who co-created the online tool that generates these estimates.

“It is really by design that Bitcoin consumes that much electricity,” Mr Rauchs told BBC’s Tech Tent podcast. “This is not something that will change in the future unless the Bitcoin price is going to significantly go down."

The online tool has ranked Bitcoin’s electricity consumption above Argentina (121 TWh), the Netherlands (108.8 TWh) and the United Arab Emirates (113.20 TWh) - and it is gradually creeping up on Norway (122.20 TWh).

The energy it uses could power all kettles used in the UK, where low-carbon generation stalled in 2019, for 27 years, it said.

However, it also suggests the amount of electricity consumed every year by always-on but inactive home devices in the US alone could power the entire Bitcoin network for a year, and in Canada, B.C. power imports have helped meet demand.

Mining Bitcoin
In order to "mine" Bitcoin, computers - often specialised ones - are connected to the cryptocurrency network.

They have the job of verifying transactions made by people who send or receive Bitcoin.

This process involves solving puzzles, which, while not integral to verifying movements of the currency, provide a hurdle to ensure no-one fraudulently edits the global record of all transactions.

As a reward, miners occasionally receive small amounts of Bitcoin in what is often likened to a lottery.

To increase profits, people often connect large numbers of miners to the network - even entire warehouses full of them, as seen with a Medicine Hat bitcoin operation backed by an electricity deal.

That uses lots of electricity because the computers are more or less constantly working to complete the puzzles, prompting some utilities to consider pauses on new crypto loads in certain regions.

The University of Cambridge tool models the economic lifetime of the world's Bitcoin miners and assumes that all the Bitcoin mining machines worldwide are working with various efficiencies.

Using an average electricity price per kilowatt hour ($0.05) and the energy demands of the Bitcoin network, it is then possible to estimate how much electricity is being consumed at any one time, though in places like China's power sector data can be opaque.

BC Hydro SAP Oversight Report assesses B.C. Utilities Commission findings on misleading testimony, governance failures, public funds oversight, IT project risk, compliance gaps, audit controls, ratepayer impacts, and regulatory accountability in major enterprise software decisions.

Key Points

A summary of BCUC findings on BC Hydro's SAP IT project oversight, governance lapses, and regulatory compliance.

✅ BCUC probed testimony, cost overruns, and governance failures

✅ Project split to avoid scrutiny; incomplete records and late corrections

✅ Reforms pledged: stronger business cases, compliance, audit controls

B.C. Hydro misled the province’s independent regulator about an expensive technology program, thereby avoiding scrutiny on how it spent millions of dollars in public money, according to a report by the B.C. Utilities Commission.

The Crown power corporation gave inaccurate testimony to regulators about the software it had chosen, called SAP, for an information technology project that has cost $197 million, said the report.

“The way the SAP decision was made prevented its appropriate scrutiny by B.C. Hydro’s board of directors and the BCUC, reflecting governance risks seen in Manitoba Hydro board changes in other jurisdictions,” the commission found.

“B.C. Hydro’s CEO and CFO and its (audit and risk management board committee) members did not exhibit good business judgment when reviewing and approving the SAP decision without an expenditure approval or business case, highlighting how board upheaval at Hydro One can carry market consequences.”

The report was the result of a complaint made in 2016 by then-opposition NDP MLA Adrian Dix, who alleged B.C. Hydro lied to the regulatory commission to try to get approval for a risky IT project in 2008 that then went over budget and resulted in the firing of Hydro’s chief information officer.

The commission spent two years investigating. Its report outlined how B.C. Hydro split the IT project into smaller components to avoid scrutiny, failed to produce the proper planning document when asked, didn’t disclose cost increases of up to $38 million, reflecting pressures seen at Manitoba Hydro's debt across the sector, gave incomplete testimony and did not quickly correct the record when it realized the mistakes.

“Essentially all of the things I asserted were substantiated, and so I’m pleased,” Dix, who is now minister of health, said on Monday. “I think ratepayers can be pleased with it, because even though it was an elaborate process, it involves hundreds of millions of spending by a public utility and it clearly required oversight.”

The BCUC stopped short of agreeing with Dix’s allegation that the errors were deliberate. Instead it pointed toward a culture at B.C. Hydro of confusion, misunderstanding and fear of dealing with the independent regulatory process.

“Therefore, the panel finds that there was a culture of reticence to inform the BCUC when there was doubt about something, even among individuals that understood or should have understood the role of the BCUC, a pattern that can fuel Hydro One investor concerns in comparable markets,” read the report.

“Because of this doubt and uncertainty among B.C. Hydro staff, the panel finds no evidence to support a finding that the BCUC was intentionally misled. The panel finds B.C. Hydro’s culture of reticence to be inappropriate.”

By law, B.C. Hydro is supposed to get approval by the commission for rate changes and major expenditures. Its officials are often put under oath when providing information.

B.C. Hydro apologized for its conduct in 2016. The Crown corporation said Monday it supports the commission’s findings and has made improvements to management of IT projects, including more rigorous business case analyses.

“We participated fully in the commission’s process and acknowledged throughout the inquiry that we could have performed better during the regulatory hearings in 2008,” said spokesperson Tanya Fish.

“Since then, we have taken steps to ensure we meet the highest standards of openness and transparency during regulatory proceedings, including implementing a (thorough) awareness program to support staff in providing transparent and accurate testimony at all times during a regulatory process.”

The Ministry of Energy, which is responsible for B.C. Hydro, said in a statement it accepts all of the BCUC recommendations and will include the findings as part of a review it is conducting into Hydro’s operations and finances, including its deferred operating costs for context, and regulatory oversight.

Dix, who is now grappling with complex IT project management in his Health Ministry, said the lessons learned by B.C. Hydro and outlined in the report are important.

“I think the report is useful reading on all those scores,” he said. “It’s a case study in what shouldn’t happen in a major IT project.”

Ontario Electricity Grid Decarbonization outlines the IESO's net-zero pathway: $400B investment, nuclear expansion, renewables, hydrogen, storage, and demand management to double capacity by 2050 while initiating a 2027 natural gas moratorium.

Key Points

A 2050 plan to double capacity, retire gas, and invest $400B in nuclear, renewables, and storage for a net-zero grid.

✅ $400B over 25 years to meet net-zero electricity by 2050

✅ Capacity doubles to 88,000 MW; demand grows ~2% annually

✅ 2027 gas moratorium; build nuclear, renewables, storage

Ontario will need to spend $400 billion over the next 25 years in order to decarbonize the electricity grid and embrace clean power according to a new report by the province’s electricity system manager that’s now being considered by the Ford government.

The Independent System Electricity Operator (IESO) was tasked with laying out a path to reducing Ontario’s reliance on natural gas for electricity generation and what it would take to decarbonize the entire electricity grid by 2050.

Meeting the goal, the IESO concluded, will require an “aggressive” approach of doubling the electricity capacity in Ontario over the next two-and-a-half decades — from 42,000 MW to 88,000 MW — by investing in nuclear, hydrogen and wind and solar power while implementing conservation policies and managing demand.

“The process of fully eliminating emissions from the grid itself will be a significant and complex undertaking,” IESO president Lesley Gallinger said in a news release.

The road to decarbonization, the IESO said, begins with a moratorium on natural gas power generation starting in 2027 as long as the province has “sufficient, non-emitting supply” to meet the growing demands on the grid.

The approach, however, comes with significant risks.

The IESO said hydroelectric and nuclear facilities can take 10 to 15 years to build and if costs aren’t controlled the plan could drive up the price of clean electricity, turning homeowners and businesses away from electrification.

“Rapidly rising electricity costs could discourage electrification, stifle economic growth or hurt consumers with low incomes,” the report states.

The IESO said the province will need to take several “no regret” actions, including selecting sites and planning to construct new large-scale nuclear plants as well as hydroelectric and energy storage projects and expanding energy-efficiency programs beyond 2024.

Ontario’s minister of energy didn’t immediately commit to implementing the recommendations, citing the need to consult with stakeholders first.

“I look forward to launching a consultation in the new year on next steps from today’s report, including the potential development of major nuclear, hydroelectric and transmissions projects,” Todd Smith said in a statement.

Currently, electricity demand is increasing by roughly two per cent per year, raising concerns Ontario could be short of electricity in the coming years as the manufacturing and transportation sectors electrify and as more sectors consider decarbonization.

At the same time, the province’s energy supply is facing “downward pressure” with the Pickering nuclear power plant slated to wind down operations and the Darlington nuclear generating station under active refurbishment.

To meet the energy need, the Ford government said it intended to extend the life of the Pickering plant until 2026.

But to prepare for the increase, the Ontario government was told the province would also need to build new natural gas facilities to bridge Ontario’s electricity supply gap in the near term — a recommendation the Ford government agreed to.

The IESO said a request for proposals has been opened and the province is looking for host communities, with the expectation that existing facilities would be upgraded before projects on undeveloped land would be considered.

The IESO said the contract for any new facilities would expire in 2040, and all natural gas facilities would be retired in the 2040s.
