Just in time for the opening of the 2008 Olympic Games, Taiyanggong Gas Thermal Power Plant, the largest combined-cycle power plant in China, was put into official operation in Beijing on July 22.

Taiyanggong Gas Thermal Power Plant is an important support project for the Beijing 2008 Olympic Games. The project is built and operated by Beijing Taiyanggong Gas Thermal Power Company Limited (BTGTPC), a project company jointly invested by Power Beijing and GD Power Development Company Limited, the listed flagship of China Guodian Corporation.

The project is furnished with two 350-megawatt (MW) 9F-class gas-steam combined-cycle generating units with an annual power output of about 3.4 billion kilowatt-hours and a heat-supply capacity of 10 million square meters in an area of 40 square kilometers.

During the construction of the project, BTGTPC overcame a series of technical difficulties such as arrangement of the units and noise treatment. With strong support from the municipal government, construction quality, progress and cost control are within desired boundaries.

Unit 1 of the plant was successfully connected to the grid on December 29, 2007, and Unit 2 passed the 168-hour trial operation in March 2008.

The project is currently ready to supply heat and power to the Olympic venues.

Western Canada drought impacting hydropower production as reservoirs run low

Western Canada Hydropower Drought strains British Columbia and Manitoba as reservoirs hit historic lows, cutting hydroelectric output and prompting power imports, natural gas peaking, and grid resilience planning amid climate change risks this winter.

 

Key Points

Climate-driven reservoir lows cut hydro in B.C. and Manitoba, prompting imports and backup gas to maintain reliability.

✅ Reservoirs at multi-year lows cut hydro generation capacity

✅ BC Hydro and Manitoba Hydro import electricity for reliability

✅ Natural gas turbines used; climate change elevates drought risk

 

Severe drought conditions in Western Canada are compelling two hydroelectricity-dependent provinces, British Columbia and Manitoba, to import power from other regions. These provinces, known for their reliance on hydroelectric power, are facing reduced electricity production due to low water levels in reservoirs this autumn and winter as energy-intensive customers encounter temporary connection limits.

While there is no immediate threat of power outages in either province, experts indicate that climate change is leading to more frequent and severe droughts. This trend places increasing pressure on hydroelectric power producers in the future, spurring interest in upgrading existing dams as part of adaptation strategies.

In British Columbia, several regions are experiencing "extreme" drought conditions as classified by the federal government. BC Hydro spokesperson Kyle Donaldson referred to these conditions as "historic," and a first call for power highlights the strain, noting that the corporation's large reservoirs in the north and southeast are at their lowest levels in many years.

To mitigate this, BC Hydro has been conserving water by utilizing less affected reservoirs and importing additional power from Alberta and various western U.S. states. Donaldson confirmed that these measures would persist in the upcoming months.

Manitoba is also facing challenges with below-normal levels in reservoirs and rivers. Since October, Manitoba Hydro has occasionally relied on its natural gas turbines to supplement hydroelectric production as electrical demand could double over the next two decades, a measure usually reserved for peak winter demand.

Bruce Owen, a spokesperson for Manitoba Hydro, reassured that there is no imminent risk of a power shortage. The corporation can import electricity from other regions, similar to how it exports clean energy in high-water years.

However, the cost implications are significant. Manitoba Hydro anticipates a financial loss for the current fiscal year, with more red ink tied to emerging generation needs, the second in a decade, with the previous one in 2021. That year, drought conditions led to a significant reduction in the company's power production capabilities, resulting in a $248-million loss.

The 2021 drought also affected hydropower production in the United States. The U.S. Department of Energy reported a 16% reduction in overall generation, with notable decreases at major facilities like Nevada's Hoover Dam, where production dropped by 25%.

Drought has long been a major concern for hydroelectricity producers, and they plan their operations with this risk in mind. Manitoba's record drought in 1940-41, for example, is a benchmark for Manitoba Hydro's operational planning to ensure sufficient electricity supply even in extreme low-water conditions.

Climate change, however, is increasing the frequency of such rare events, highlighting the need for more robust backup systems such as new turbine investments to enhance reliability. Blake Shaffer, an associate professor of economics at the University of Calgary specializing in electricity markets, emphasized the importance of hydroelectric systems incorporating the worsening drought forecasts due to climate change into their energy production planning.

Britain's National Grid Drops China-Based Supplier Over Cybersecurity Fears

National Grid Cybersecurity Component Removal signals NCSC and GCHQ oversight of critical infrastructure, replacing NR Electric and Nari Technology grid control systems to mitigate supply chain risk, cyber threats, and blackout risk.

 

Key Points

A UK move to remove China-linked grid components after NCSC/GCHQ advice, reducing cyber and blackout risks.

✅ NCSC advice to remove NR Electric components

✅ GCHQ-linked review flags critical infrastructure risks

✅ Aims to cut blackout risk and supply chain exposure

 

Britain's National Grid has started removing components supplied by a unit of China-backed Nari Technology's from the electricity transmission network over cybersecurity fears, reflecting a wider push on protecting the power grid across critical sectors.

The decision came in April after the utility sought advice from the National Cyber Security Center (NCSC), a branch of the nation's signals intelligence agency, Government Communications Headquarters (GCHQ), amid campaigns like the Dragonfly campaign documented by Symantec, the newspaper quoted a Whitehall official as saying.

National Grid declined to comment citing "confidential contractual matters." "We take the security of our infrastructure very seriously and have effective controls in place to protect our employees and critical assets, while preparing for an independent operator transition in Great Britain, to ensure we can continue to reliably, safely and securely transmit electricity," it said in a statement.

The report said an employee at the Nari subsidiary, NR Electric Company-U.K., had said the company no longer had access to sites where the components were installed, at a time when utilities worldwide have faced control-room intrusions by state-linked hackers, and that National Grid did not disclose a reason for terminating the contracts.

It quoted another person it did not name as saying the decision was based on NR Electric Company-U.K.'s components that help control and balance the grid, respond to work-from-home demand shifts, and minimize the risk of blackouts.

It was unclear whether the components remained in the electricity transmission network, the report said, amid reports of U.S. power plant breaches that have heightened vigilance.

NR Electric Company-U.K., GCHQ and the Chinese Embassy in London did not immediately respond to requests for comment outside of business hours.

Britain's Department for Energy Security and Net Zero said that it did not comment on the individual business decisions taken by private organizations. "As a government department we work closely with the private sector to safeguard our national security, and to support efforts to fast-track grid connections across the network," it said in a statement.

Cost, safety drive line-burying decisions at Tucson Electric Power

TEP Undergrounding Policy prioritizes selective underground power lines to manage wildfire risk, engineering costs, and ratepayer impacts, balancing transmission and distribution reliability with right-of-way, safety, and vegetation management per Arizona regulators.

 

Key Points

A selective TEP approach to bury lines where safety, engineering, and cost justify undergrounding.

✅ Selective undergrounding for feeders near substations

✅ Balances wildfire mitigation, reliability, and ratepayer costs

✅ Follows ACC rules, BLM and USFS vegetation management

 

Though wildfires in California caused by power lines have prompted calls for more underground lines, Tucson Electric Power Co. plans to keep to its policy of burying lines selectively for safety.

Like many other utilities, TEP typically doesn’t install its long-range, high-voltage transmission lines, such as the TransWest Express project, and distribution equipment underground because of higher costs that would be passed on to ratepayers, TEP spokesman Joe Barrios said.

But the company will sometimes bury lower-voltage lines and equipment where it is cost-effective or needed for safety as utilities adapt to climate change across North America, or if customers or developers are willing to pay the higher installation costs

Underground installations generally include additional engineering expenses, right-of-way acquisition for projects like the New England Clean Power Link in other regions, and added labor and materials, Barrios said.

“This practice avoids passing along unnecessary costs to customers through their rates, so that all customers are not asked to subsidize a discretionary expenditure that primarily benefits residents or property owners in one small area of our service territory,” he said, adding that the Arizona Corporation Commission has supported the company’s policy.

Even so, TEP will place equipment underground in some circumstances if engineering or safety concerns, including electrical safety tips that utilities promote during storm season, justify the additional cost of underground installation, Barrios said.

In fact, lower-voltage “feeder” lines emerging from distribution substations are typically installed underground until the lines reach a point where they can be safely brought above ground, he added.

While in California PG&E has shut off power during windy weather to avoid wildfires in forested areas traversed by its power lines after events like the Drum Fire last June, TEP doesn’t face the same kind of wildfire risk, Barrios said.

Most of TEP’s 5,000 miles of transmission and distribution lines aren’t located in heavily forested areas that would raise fire concerns, though large urban systems have seen outages after station fires in Los Angeles, he said.

However, TEP has an active program of monitoring transmission lines and trimming vegetation to maintain a fire-safety buffer zone and address risks from vandalism such as copper theft where applicable, in compliance with federal regulations and in cooperation with the U.S. Bureau of Land Management and the U.S. Forest Service.

Alberta Introduces New Electricity Rules

Alberta Rate of Last Resort streamlines electricity regulations to stabilize the default rate, curb price volatility, and protect rural communities, low-income households, and seniors while preserving competition in the province's energy market.

 

Key Points

Alberta's Rate of Last Resort sets biennial default electricity prices, curbing volatility and protecting customers.

✅ Biennial default rate to limit price spikes

✅ Focus on rural, senior, and low-income customers

✅ Encourages competitive contracts and market stability

 

The Alberta government is overhauling its electricity regulations as part of a market overhaul aimed at reducing spikes in electricity prices for consumers and businesses. The new rules, set to be introduced this spring, are intended to stabilize the default electricity rate paid by many Albertans.


Background on the Rate of Last Resort

Albertans currently have the option to sign up for competitive contracts with electricity providers. These contracts can sometimes offer lower rates than the default electricity rate, officially known as the Regulated Rate Option (RRO). However, these competitive rates can fluctuate significantly. Currently, those unable to secure these contracts or those who are on the default rate are experiencing rising electricity prices and high levels of price volatility.

To address this, the Alberta government is renaming the default rate as the Rate of Last Resort designation (RoLR) under the new framework. This aims to reduce the sense of security that some consumers might associate with the current name, which the government feels is misleading.


Key Changes Under New Regulations

The new regulations, which include proposed market changes that affect pricing, focus on:

  • Price Stabilization: Default electricity rates will be set every two years for each utility provider, providing greater predictability by enabling a consumer price cap and reducing the potential for extreme price swings.
  • Rural and Underserved Communities: The changes are intended to particularly benefit rural Albertans and those on the default rate, including low-income individuals and seniors. These groups often lack access to the competitive rates offered by some providers and have been disproportionately affected by recent price increases.
  • Promoting Economic Stability: The goal is to lower the cost of utilities for all Albertans, leading to overall lower costs of living and doing business. The government anticipates these changes will create a more attractive environment for investment and job creation.


Opposition Views

Critics argue that limiting the flexibility of prices for the default electricity rate could interfere with market dynamics and stifle market competition among providers. Some worry it could ultimately lead to higher prices in the long term. Others advocate directly subsidizing low-income households rather than introducing broad price controls.


Balancing Affordability and the Market

The Alberta government maintains that the proposed changes will strike a balance between ensuring affordable electricity for vulnerable Albertans and preserving a competitive energy market. Provincial officials emphasize that the new regulations should not deter consumers from seeking out competitive rates if they choose to.


The Path Ahead

The new electricity regulations are part of the Alberta government's broader Affordable Utilities Program, alongside electricity policy changes across the province. The legislation is expected to be introduced and debated in the provincial legislature this spring with the potential of coming into effect later in the year. Experts expect these changes will significantly impact the Alberta electricity market and ignite further discussion about how best to manage rising utility costs for consumers and businesses.

Hydro One’s takeover of U.S. utility sparks customer backlash: ‘This is an incredibly bad idea’

Hydro One-Avista acquisition sparks Idaho regulatory scrutiny over foreign ownership, utility merger impacts, rate credits, and public interest, as FERC and FCC approvals advance and consumers question governance, service reliability, and long-term rate stability.

 

Key Points

A cross-border utility merger proposal with Idaho oversight, weighing foreign ownership, rates, and reliability.

✅ Idaho PUC review centers on public interest and rate impacts.

✅ FERC and FCC approvals granted; state decisions pending.

✅ Avista to retain name and Spokane HQ post-transaction.

 

“Please don’t sell us to Canada.” That refrain, or versions of it, is on full display at the Idaho Public Utilities Commission, which admittedly isn’t everyone’s go-to entertainment site. But it is vitally important for this reason: the first big test of the expansionist dreams of the politically tempest-tossed Hydro One, facing political risk as it navigates markets, rests with its successful acquisition of Avista Corp., provider of electric generation, transmission and distribution to retail customers spread from Oregon to Washington to Montana and Idaho and up into Alaska.

The proposed deal — announced last summer, but not yet consummated — marks the first time the publicly traded Hydro One has embarked upon the acquisition of a U.S. utility. And if Idahoans spread from Boise to Coeur d’Alene to Hayden are any indication, they are not at all happy with the idea of foreign ownership. Here’s Lisa McCumber, resident of Hayden: “I am stating my objection to this outrageous merger/takeover. Hydro One charges excessive fees to the people it provides for, this is a monopoly beyond even what we are used to. I, in no way, support or as a customer, agree with the merger of this multi-billion-dollar, foreign, company.”

#google#

Or here’s Debra Bentley from Coeur d’Alene: “Fewer things have more control over a nation than its power source. In an age where we are desperately trying to bring American companies back home and ‘Buy American’ is somewhat of a battle cry, how is it even possible that it would or could be allowed for this vital necessity … to be controlled by a foreign entity?”

Or here’s Spencer Hutchings from Sagle: “This is an incredibly bad idea.”

There are legion of similar emails from concerned consumers, and the Maine transmission line debate offers a parallel in public opposition.

The rationale for the deal? Last fall Hydro One CEO Mayo Schmidt testified before the Idaho commission, which regulates all gas, water and electricity providers in the state. “Hydro One is a pure-play transmission and distribution utility located solely within Ontario,” Schmidt told commissioners. “It seeks diversification both in terms of jurisdictions and service areas. The proposed Transaction with Avista achieves both goals by expanding Hydro One into the U.S. Pacific Northwest and expanding its operations to natural gas distribution and electric generation. The proposed Transaction with Avista will deliver the increased scale and benefits that come from being a larger player in the utility industry.”

Translation: now that it is a publicly traded entity, Hydro needs to demonstrate a growth curve to the investment community. The value to you and me? Arguable. This is a transaction framed as a benefit to shareholders, one that won’t cause harm to customers. Premier Kathleen Wynne is feeling the pain of selling off control of an essential asset. In his testimony to the commission, Schmidt noted that the Avista acquisition would take the province’s Hydro ownership to under 45 per cent. (The Electricity Act technically prevents the sale of shares that would take the government’s ownership position below 40 per cent, though acquisitions appear to allow further dilution. )

Stratospheric compensation, bench-marked against other chief executives who enjoy similarly outsized rewards, is part of this game. I have written about Schmidt’s unconscionable compensation before, but that was when he was making a relatively modest $4 million. Relative, that is, to his $6.2 million in 2017 compensation ($3.5 million of that is in the form of share based awards).

Should the acquisition of Avista be approved, amendments to the CIC, or change in control agreements, for certain named Avista executive officers will allow them to voluntarily terminate their employment without “good reason.” That includes Scott Morris, the company’s CEO, who will exit with severance of $6.9 million (U.S.) and additional benefits taking the total to a potential $15.7 million.

Back to the deal: cost savings over time could be achieved, Schmidt continued in his testimony, though he was unable to quantify those. The integration between the two companies, he promised, will be “seamless.” Retail customers in Idaho, Washington and Oregon would benefit from proposed “Rate Credits” equalling an estimated $15.8 million across five years, even as Hydro One seeks to redesign its bills in Ontario. Idahoans would see a one per cent rate decrease through that period.

While Avista would become a wholly owned Hydro subsidiary, it would retain its name, and its headquarters in Spokane, Wash. In the case of Idaho specifically, a proposed settlement in April, subject to final approval by the commission, stipulates agreements on everything from staffing to governance to community contributions.

Will that meet the test? It’s up to the commission to determine whether the proposed transaction will keep a lid on rates and is “consistent with the public interest.” Hydro One is hoping for a decision from regulatory agencies in all the named states by mid-August and a closing date by the end of September, though U.S. regulators can ultimately determine the fate of such deals. The Federal Energy Regulatory Commission granted its approval in January, followed last week by the Federal Communications Commission. Washington and Alaska have reached settlement agreements. These too are pending final state approvals.

The $5.3-billion deal (or $6.7 billion Canadian) is subject to ongoing hearings in Idaho, and elsewhere rate hikes face opposition as hearings begin. Members of the public are encouraged to have their say. The public comment deadline is June 27.

TTC Introduces Battery Electric Buses

TTC Battery-Electric Buses lead Toronto transit toward zero-emission mobility, improving air quality and climate goals with sustainable operations, advanced charging infrastructure, lower maintenance, energy efficiency, and reliable public transportation across the Toronto Transit Commission network.

 

Key Points

TTC battery-electric buses are zero-emission vehicles improving quality, lowering costs, and providing efficient service.

✅ Zero tailpipe emissions improve urban air quality

✅ Lower maintenance and energy costs increase savings

✅ Charging infrastructure enables reliable operations

 

The Toronto Transit Commission (TTC) has embarked on an exciting new chapter in its commitment to sustainability with the introduction of battery-electric buses to its fleet. This strategic move not only highlights the TTC's dedication to reducing its environmental impact but also positions Toronto as a leader in the evolution of public transportation. As cities worldwide strive for greener solutions, the TTC’s initiative stands as a significant milestone toward a more sustainable urban future.

Embracing Green Technology

The decision to integrate battery-electric buses into Toronto's transit system aligns with a growing trend among urban centers to adopt cleaner, more efficient technologies, including Metro Vancouver electric buses now in service. With climate change posing urgent challenges, transit authorities are rethinking their operations to foster cleaner air and reduce greenhouse gas emissions. The TTC’s new fleet of battery-electric buses represents a proactive approach to addressing these concerns, aiming to create a cleaner, healthier environment for all Torontonians.

Battery-electric buses operate without producing tailpipe emissions, and deployments like Edmonton's first electric bus illustrate this shift, offering a stark contrast to traditional diesel-powered vehicles. This transition is crucial for improving air quality in urban areas, where transportation is a leading source of air pollution. By choosing electric options, the TTC not only enhances the city’s air quality but also contributes to the global effort to combat climate change.

Economic and Operational Advantages

Beyond environmental benefits, battery-electric buses present significant economic advantages. Although the initial investment for electric buses may be higher than that for conventional diesel buses, and broader adoption challenges persist, the long-term savings are substantial. Electric buses have lower operating costs due to reduced fuel expenses and less frequent maintenance requirements. The electric propulsion system generally involves fewer moving parts than traditional engines, resulting in lower overall maintenance costs and improved service reliability.

Moreover, the increased efficiency of electric buses translates into reduced energy consumption. Electric buses convert a larger proportion of energy from the grid into motion, minimizing waste and optimizing operational effectiveness. This not only benefits the TTC financially but also enhances the overall experience for riders by providing a more reliable and punctual service.

Infrastructure Development

To support the introduction of battery-electric buses, the TTC is also investing in necessary infrastructure upgrades, including the installation of charging stations throughout the city. These charging facilities are essential for ensuring that the electric fleet can operate smoothly and efficiently. By strategically placing charging stations at transit hubs and along bus routes, the TTC aims to create a seamless transition for both operators and riders.

This infrastructure development is critical not just for the operational capacity of the electric buses but also for fostering public confidence in this new technology, and consistent safety measures such as the TTC's winter safety policy on lithium-ion devices reinforce that trust. As the TTC rolls out these vehicles, clear communication regarding their operational logistics, including charging times and routes, will be essential to inform and engage the community.

Engaging the Community

The TTC is committed to engaging with Toronto’s diverse communities throughout the rollout of its battery-electric bus program. Community outreach initiatives will help educate residents about the benefits of electric transit, addressing any concerns and building public support, and will also discuss emerging alternatives like Mississauga fuel cell buses in the region. Informational campaigns, workshops, and public forums will provide opportunities for dialogue, allowing residents to voice their opinions and learn more about the technology.

This engagement is vital for ensuring that the transition is not just a top-down initiative but a collaborative effort that reflects the needs and interests of the community. By fostering a sense of ownership among residents, the TTC can cultivate support for its sustainable transit goals.

A Vision for the Future

The TTC’s introduction of battery-electric buses marks a transformative moment in Toronto’s public transit landscape. This initiative exemplifies the commission's broader vision of creating a more sustainable, efficient, and user-friendly transportation network. As the city continues to grow, the need for innovative solutions to urban mobility challenges becomes increasingly critical.

By embracing electric technology, the TTC is setting an example for other transit agencies across Canada and beyond, and piloting driverless EV shuttles locally underscores that leadership. This initiative is not just about introducing new vehicles; it is about reimagining public transportation in a way that prioritizes environmental responsibility and community engagement. As Toronto moves forward, the integration of battery-electric buses will play a crucial role in shaping a cleaner, greener future for urban transit, ultimately benefitting residents and the planet alike.
