Electricity users could pay a few cents more for their power if the Idaho Public Utilities Commission approves a request from Idaho Power Company.

The utility wants to incorporate money it spends buying geothermal energy as part of a formula called a "power cost adjustment." The company uses the PCA formula to either grant discounts or levy surcharges to customers each spring.

Depending on how much water flows through the company's hydroelectric facilities each year, Idaho Power either discounts customers or charges extra. If the commission approves the request, customers could pay more on their bills to also cover in part what it costs the utility to buy electricity from a geothermal plant near Malta owned by Boise-based U.S. Geothermal.

The commission and Idaho Power say the costs aren't likely to break anyone's bank.

"The costs will be insignificant," said Dennis Lopez, an Idaho Power spokesman.

Under a contract with the company, Idaho Power will pay about $52.50 for each megawatt-hour produced at the plant. The market rate was $68.02 for peak electricity on December 10 and $54.75 for non-peak power. Idaho Power will buy about 13 megawatts from the company under a 25-year agreement in which costs escalate over time.

In 2032, for example, the utility will pay $73.92 for each megawatt-hour. U.S. Geothermal is offering to sell 45.5 megawatts to the utility, and a deal to buy that power could develop later.

Idaho Power plans to buy 200 megawatts of geothermal electricity by 2022. Ten megawatts can meet the electricity needs of about 7,500 people. Geothermal power is more reliable than wind and solar energy, it has virtually no emissions and it has promising potential in Idaho, according to a 2006 report by the Geothermal Energy Association.

That report cited a January 2006 study by the Geothermal Task Force of the Western Governors' Association that estimated Idaho could produce 850 megawatts of geothermal electricity by 2015 and 1,670 megawatts by 2025. Just 850 megawatts is enough to meet 30 percent of Idaho's energy needs.

The U.S. Geothermal plant, which is already selling about 10 megawatts of electricity to Idaho Power, is expected to be selling its contracted amount by June. It is Idaho's first commercial geothermal electricity plant. Eventually, the plant, built on an abandoned Department of Energy test site, could produce 100 megawatts of power at its full capacity.

For comparison, Idaho Power Co.'s Milner Dam - just one of 17 hydro facilities run by the utility company - has a 58-megawatt capacity.

This Floating Hotel Will Generate Electricity By Rotating All Day

Floating Rotating Eco Hotel harnesses renewable energy via VAWTAU, recycles rainwater for greywater, and follows zero-waste principles. This mobile, off-grid, Qatar-based resort generates electricity by slow 360-degree rotation while offering luxury amenities.

 

Key Points

A mobile, off-grid hotel that rotates to generate power, uses VAWTAU, recycles greywater, and targets zero-waste.

✅ Rotates 360 deg in 24 hours to produce electricity

✅ VAWTAU system: vertical-axis turbine and sun umbrella

✅ Rain capture and greywater recycling minimize waste

 

A new eco-friendly, floating hotel plans to generate its own electricity by rotating while guests relax on board, echoing developments like the solar Marriott hotel in sustainable hospitality.

Led by Hayri Atak Architectural Design Studio (HAADS), the structure will be completely mobile, meaning it can float from place to place, never sitting in a permanent position. Building began in March 2020 and the architects aim for it to be up and running by 2025.

It will be based in Qatar, but has the potential to be located in different areas due to its mobility, and it sits within a region advancing projects such as solar hydrogen production that signal a broader clean-energy shift.

The design includes minimum energy loss and a zero waste principle at its core, aligning with progress in wave energy research that aims to power a clean future. As it will rotate around all day long, this will generate electrical energy to power the whole hotel.

But guests won’t feel too dizzy, as it takes 24 hours for the hotel to spin 360 degrees.

The floating hotel will stay within areas with continuous currents, to ensure that it is always rotating, drawing on ideas from ocean and river power systems that exploit natural flows. This type of green energy production is called ‘vawtau’ (vertical axis wind turbine and umbrella) which works like a wind turbine on the vertical axis, while alternative approaches like kite-based wind energy target stronger, high-altitude currents as well, and functions as a sun umbrella on the coastal band.

Beyond marine-current concepts such as underwater kites, the structure will also make use of rainwater to create power. A cover on the top of the hotel will collect rain to be used for greywater recycling. This is when wastewater is plumbed straight back into toilets, washing machines or outside taps to maximise efficiency.

The whole surface area is around 35,000 m², comparable in scale to emerging floating solar plants that demonstrate modular, water-based infrastructure, and there are a total of 152 rooms. It will have three different entrances so that there is access to the land at any time of the day, thanks to the 140-degree pier that surrounds it.

There will also be indoor and outdoor swimming pools, a sauna, spa, gym, mini golf course and other activity areas.

Ontario Businesses To See Full Impact of 2021 Electricity Rate Reductions

Ontario Comprehensive Electricity Plan delivers Global Adjustment reductions for industrial and commercial non-RPP customers, lowering electricity rates, shifting renewable energy costs, and enhancing competitiveness across Ontario businesses in 2022, with additional 4 percent savings.

 

Key Points

Ontario's plan lowers Global Adjustment by shifting renewable costs, cutting industrial and commercial bills 15-17%.

✅ Shifts above-market non-hydro renewable costs to the Province

✅ Reduces GA for industrial and commercial non-RPP customers

✅ Additional 4% savings on 2022 bills after GA deferral

 

As of January 1, 2022, industrial and commercial electricity customers will benefit from the full savings introduced through the Ontario government’s Comprehensive Electricity Plan, which supports stable electricity pricing for industrial and commercial companies, announced in Budget 2020, and first implemented in January 2021. This year customers could see an additional four percent savings compared to their bills last year, bringing the full savings from the Comprehensive Electricity Plan to between 15 and 17 per cent, making Ontario a more competitive place to do business.

“Our Comprehensive Electricity Plan has helped reverse the trend of skyrocketing electricity prices that drove jobs out of Ontario,” said Todd Smith, Minister of Energy. “Over 50,000 customers are benefiting from our government’s plan which has reduced electricity rates on clean and reliable power, allowing them to focus on reinvesting in their operations and creating jobs here at home.”

Starting on January 1, 2021, the Comprehensive Electricity Plan reduced overall Global Adjustment (GA) costs for industrial and commercial customers who do not participate in the Regulated Price Plan (RPP) by shifting the forecast above-market costs of non-hydro renewable energy, such as wind, solar and bioenergy, from the rate base to the Province, alongside energy-efficiency programs that complement demand reduction efforts.

“Since taking office, our government has listened to job creators and worked to lower the costs of doing business in the province. Through these significant reductions in electricity prices through the Comprehensive Electricity Plan, customers all across Ontario will benefit from significant savings in their business operations in 2022,” said Vic Fedeli, Minister of Economic Development, Job Creation and Trade. “By continuing to reduce electricity costs, lowering taxes, and cutting red tape our government has reduced the cost of doing business in Ontario by nearly $7 billion annually to ensure that we remain competitive, innovative and poised for economic recovery.”

As part of its COVID response, including electricity relief for families and small businesses, Ontario had deferred a portion of GA between April and June 2020 for industrial and non-RPP commercial customers, with more than 50,000 customers benefiting. Those same businesses paid back these deferred GA costs over 12 months, between January 2021 and December 2021, while the province prepared to extend disconnect moratoriums for residential customers.

During the pandemic, residential electricity use rose even as overall consumption dropped, underscoring shifts in load patterns.

Now that the GA deferral repayment period is over, industrial and non-RPP commercial customers will benefit from the full cost reductions provided to them by the Comprehensive Electricity Plan, alongside temporary off-peak rate relief that supported families and small businesses. This means that, beginning January 1, 2022, these businesses could see an additional four per cent savings on their bills compared to 2021, as new ultra-low overnight pricing options emerge depending on their location and consumption.

Cape Town to Build Own Power Plants, Buy Additional Electricity

Cape Town Renewable Energy Plan targets 450+ MW via solar, wind, and battery storage, cutting Eskom reliance, lowering greenhouse gas emissions, stabilizing electricity prices, and boosting grid resilience through municipal procurement, PPAs, and city-owned plants.

 

Key Points

A municipal plan to procure over 450 MW, cut Eskom reliance, stabilize prices, and reduce Cape Town emissions.

✅ Up to 150 MW from private plants within the city

✅ 300 MW to be purchased from outside Cape Town later

✅ City financing 100-200 MW of its own generation

 

Cape Town is seeking to secure more than 450 megawatts of power from renewable sources to cut reliance on state power utility Eskom Holdings SOC Ltd., where wind procurement cuts were considered during lockdown, and reduce greenhouse gas emissions.

South Africa’s second-biggest city is looking at a range of options, including geothermal exploration in comparable markets, and expects the bulk of the electricity to be generated from solar plants, Kadri Nassiep, the city’s executive director of energy and climate change, said in an interview.

On July 14 the city of 4.6 million people released a request for information to seek funding to build its own plants. This month or next it will seek proposals for the provision of as much as 150 megawatts from privately owned plants, largely solar additions, to be built and operated within the city, he said. As much as 300 megawatts may also be purchased at a later stage from plants outside of Cape Town, according to Nassiep.

The city could secure finance to build 100 to 200 megawatts of its own generation capacity, Nassiep said. “We realized that it is important for the city to be more in control around the pricing of the power,” he added.

Power Outages

Cape Town’s foray into the securing of power from sources other than Eskom comes after more than a decade of intermittent electricity outages, while elsewhere in Africa coal projects face scrutiny from lenders, because the utility can’t meet national demand. The government last year said municipalities could find alternative suppliers.

Earlier this month Ethekwini, the municipal area that includes the city of Durban, issued a request for information for the provision of 400 megawatts of power, similar to BC Hydro’s call for power driven by EV uptake.

The City of Johannesburg will in September seek information and proposals for the construction of a 150-megawatt solar plant, reflecting moves like Ontario’s new wind and solar procurements to tackle supply gaps, 50 megawatts of rooftop solar panels and the refurbishment of an idle gas-fired plant that could generate 20 megawatts, it said in June. It will also seek information for the installation of 100 megawatts of battery storage.

Cape Town, which uses a peak of 1,800 megawatts of electricity in winter, hopes to start generating some of its own power next year, aligning with SaskPower’s 2030 renewables plan seen in Canada, according to a statement that accompanied its request for financing proposals.

Canada will need more electricity to hit net-zero: IEA report

Canada Clean Electricity Expansion is urged by the IEA to meet net-zero targets, scaling non-emitting generation, electrification, EV demand, and grid integration across provinces to decarbonize industry, buildings, and transport while ensuring reliability and affordability.

 

Key Points

An IEA-backed pathway for Canada to scale non-emitting power, electrification, and grid links to meet net-zero goals.

✅ Double or triple clean generation to replace fossil fuels

✅ Integrate provincial grids to decarbonize dependent regions

✅ Manage EV and heating loads with reliability and affordability

 

Canada will need more electricity capacity if it wants to hit its climate targets, and cleaning up Canada's electricity will be critical, according to a new report from the International Energy Agency (IEA).

The report offers mainly a rosy picture of Canada's overall federal energy policy. But, the IEA draws attention to Canada's increasing future electricity demands, and ultimately, calls on Canada to leverage its non-emitting energy potential and expand renewable energy to hit its climate targets.  

"Canada's wealth of clean electricity and its innovative spirit can help drive a secure and affordable transformation of its energy system and help realize its ambitious goals," stated Fatih Birol, the IEA executive director, in a news release.

The IEA notes that Canada has one of the cleanest energy grids globally, with 83 per cent of electricity coming from non-emitting sources in 2020. But this reflects nationwide progress in electricity to date; the report warns this is not a reason for Canada to rest on its laurels. More electricity will be needed to displace fossil fuels if Canada wants to hit its 2030 targets, the report states, and "even deeper cuts" will be required to reach net-zero by 2050.

"Perhaps more significantly, however, Canada will need to ensure sufficient new clean generation capacity to meet the sizeable levels of electrification that its net-zero targets imply."

Investing in new coal, oil and gas projects must stop to hit climate goals, global energy agency says
The Liberals have promised to create a 100 percent net-zero-emitting electricity system by 2035, with regulating oil and gas emissions and electric car sales as part of the plan; by then, every new light-duty vehicle sold in Canada will be a zero-emission vehicle. The switch from gas guzzlers to plug-in electric vehicles will create new pressures on Canada's electrical grid, as will any turn away from fossil natural gas for home heating.

To meet these challenges, the IEA warns, Canada would need to double or triple the power generated from non-emitting sources compared to today, a shift whose cost could reach $1.4 trillion according to the Canadian Gas Association. 

"Such a shift will require significant regulatory action," the report states, highlighting the need for climate policy for electricity grids to guide implementation, and that will require the federal government to work closely with provinces and territories that control power generation and distribution.

The report notes that the further integration of territorial and provincial electrical grids could allow fossil fuel-dependent provinces, like Alberta, to decarbonize and electrify their economies.

The report, entitled Canada 2022 Energy Policy Review, offers what it calls an "in-depth" look at the commitments Canada has made to transform its energy policy. Since the IEA conducted its last review in 2015, Canada has committed to cutting greenhouse gas emissions by 40 to 45 per cent from 2005 levels by 2030 and achieving net-zero by 2050 under an extended national target.

The IEA is well-known for the production of its annual World Energy Outlook. The Paris-based autonomous intergovernmental organization provides analysis, data, and policy recommendations to promote global energy security and sustainability. Canada is a part of the intergovernmental body, which also conducts peer reviews of its members' energy policy.


Oil and gas emissions rising
Natural Resources Minister Jonathan Wilkinson responded to the report in the IEA news release.

"This report acknowledges Canada's ambitious efforts and historic investments to develop pathways to achieve net-zero emissions by 2050 and ensure a transition that aligns with our shared objective of limiting global warming to 1.5 degrees Celsius," Wilkinson's statement read.

The report notes that — despite that objective — absolute emissions from Canadian oil and gas extraction went up 26 per cent between 2000 and 2019, largely from increased production.

"Canada will need to reconcile future growth in oil sands production with increasingly strict greenhouse gas requirements," the report states.

On the plus side, the IEA found emissions per barrel of oilsands crude have decreased by 20 per cent in the last decade from technical and operational improvements.

The improving carbon efficiency of the oilsands is a "trend that is expected to continue at even higher rates," said Ben Brunnen, vice-president of oilsands, fiscal and economic policy at the Canadian Association of Petroleum Producers.

That may become important, the IEA report notes, as energy investors and buyers look for low-carbon assets and more countries adopt net-zero policies.

Further innovation, such as carbon capture and storage, could help to turn things around for Canada's oil patch, the report says. The Liberals have also said they will place a hard cap on oil and gas emissions from production, but that does not include the burning of the fossil fuels. 

In 2021, the IEA released a report that determined to achieve net-zero by 2050, among many steps, investments needed to end in coal mines, oil and gas wells. Thursday's report, however, made no mention of that, which disappointed at least one environmental group.

"A glaring omission was that this assessment says nothing about production. We know that the most important thing we can do is to stop using and producing oil and gas," said Julia Levin, a senior climate and energy program manager at Environmental Defence.

"And yet that was absent from this report, and that really is a glaring omission, which is completely out of line with their [the IEA's] own work."

Project examines potential for Europe's power grid to increase HVDC Technology

HVDC-WISE Project accelerates HVDC technology integration across the European transmission system, delivering a planning toolkit to boost grid reliability, resilience, and interconnectors for renewables and offshore wind amid climate, cyber, and physical threats.

 

Key Points

EU-funded project delivering tools to integrate HVDC into Europe's grid, improving reliability, resilience, and security.

✅ EU Horizon Europe-backed consortium of 14 partners

✅ Toolkit to assess extreme events and grid operability

✅ Supports interconnectors, offshore wind, and renewables

 

A partnership of 14 leading European energy industry companies, research organizations and universities has launched a new project to identify opportunities to increase integration of HVDC technology into the European transmission system, echoing calls to invest in smarter electricity infrastructure from abroad.

The HVDC-WISE project, in which the University of Strathclyde is the UK’s only academic partner, is supported by the European Union’s Horizon Europe programme.

The project’s goal is to develop a toolkit for grid developers to evaluate the grid’s performance under extreme conditions and to plan systems, leveraging a digital grid approach that supports coordination to realise the full range of potential benefits from deep integration of HVDC technology into the European transmission system.

The project is focused on enhancing electric grid reliability and resilience while navigating the energy transition. Building and maintaining network infrastructure to move power across Europe is an urgent and complex task, and reducing losses with superconducting cables can play a role, particularly with the continuing growth of wind and solar generation. At the same time, threats to the integrity of the power system are on the rise from multiple sources, including climate, cyber, and physical hazards.

 

Mutual support

At a time of increasing worries about energy security and as Europe’s electricity systems decarbonise, connections between them to provide mutual support and routes to market for energy from renewables, a dynamic also highlighted in discussions of the western Canadian electricity grid in North America, become ever more important.

In modern power systems, this means making use of High Voltage Direct Current (HVDC) technology.

The earliest forms of technology have been around since the 1960s, but the impact of increasing reliance on HVDC and its ability to enhance a power system’s operability and resilience are not yet fully understood.

Professor Keith Bell, Scottish Power Professor of Future Power Systems at the University of Strathclyde, said:

As an island, HVDC is the only practical way for us to build connections to other countries’ electricity systems. We’re also making use of it within our system, with one existing and more planned Scotland-England subsea link projects connecting one part of Britain to another.

“These links allow us to maximise our use of wind energy. New links to other countries will also help us when it’s not windy and, together with assets like the 2GW substation now in service, to recover from any major disturbances that might occur.

“The system is always vulnerable to weather and things like lightning strikes or short circuits caused by high winds. As dependency on electricity increases, insights from electricity prediction specialists can inform planning as we enhance the resilience of the system.”

Dr Agusti Egea-Alvarez, Senior Lecturer at Strathclyde, said: “HVDC systems are becoming the backbone of the British and European electric power network, either interconnecting countries, or connecting offshore wind farms.

“The tools, procedures and guides that will be developed during HVDC-WISE will define the security, resilience and reliability standards of the electric network for the upcoming decades in Europe.”

Other project participants include Scottish Hydro Electric Transmission, the Supergrid Institute, the Electric Power Research Institute (EPRI) Europe, Tennet TSO, Universidad Pontificia Comillas, TU Delft, Tractebel Impact and the University of Cyprus.

 

Climate change

Eamonn Lannoye, Managing Director of EPRI Europe, said: “The European electricity grid is remarkably reliable by any standard. But as the climate changes and the grid becomes exposed to more extreme conditions, energy interdependence between regions intensifies and threats from external actors emerge. The new grid needs to be robust to those challenges.”

Juan Carlos Gonzalez, a senior researcher with the SuperGrid Institute which leads the project said: “The HVDC-WISE project is intended to provide planners with the tools and know-how to understand how grid development options perform in the context of changing threats and to ensure reliability.”

HVDC-WISE is supported by the European Union’s Horizon Europe programme under agreement 101075424 and by the UK Research and Innovation Horizon Europe Guarantee scheme.
