Japan's wind power industry installed 183 megawatts (MW) of capacity in the year ended in March, down 1.3 percent from a year earlier, a government linked research unit said in a report.

Tighter regulations on wind turbines have restricted construction in the past two years and the world's fifth largest greenhouse gas emittor has focused more on solar panels to help to fight global warming.

Japan accounts for only 1.6 percent of the world's wind power market, which is estimated to grow by a record 30,300 MW of installed capacity this year to a total of 152,000 MW, according to the World Wind Energy Association.

The New Energy and Industrial Technology Development Organization (NEDO) said in the report that Japan's wind power installed capacity totaled 1,854 MW as of March, with 1,517 turbines.

The stricter guidelines, which stipulate that wind turbines must clear the same safety regulations that apply to tall buildings, were introduced in 2007 following a scandal over falsified engineering data for apartment blocks.

Ottawa Launches Sewage Energy Project at LeBreton Flats

Ottawa Sewage Energy Exchange System uses wastewater heat recovery and efficient heat pumps to deliver renewable district energy, zero carbon heating and cooling, cutting greenhouse gas emissions at LeBreton Flats and scaling urban developments.

 

Key Points

A district energy system recovering wastewater heat via pumps to deliver zero carbon heating and cooling.

✅ Delivers 9 MW heating and cooling for 2.4M sq ft at LeBreton Flats

✅ Cuts 5,066 tonnes CO2e each year, reducing greenhouse gases

✅ Powers Odenak zero carbon housing via district energy

 

Ottawa is embarking on a groundbreaking initiative to harness the latent thermal energy within its wastewater system, in tandem with advances in energy storage in Ontario that strengthen grid resilience, marking a significant stride toward sustainable urban development. The Sewage Energy Exchange System (SEES) project, a collaborative effort led by the LeBreton Community Utility Partnership—which includes Envari Holding Inc. (a subsidiary of Hydro Ottawa) and Theia Partners—aims to revolutionize how the city powers its buildings.

Harnessing Wastewater for Sustainable Energy

The SEES will utilize advanced heat pump technology to extract thermal energy from the city's wastewater infrastructure, providing both heating and cooling to buildings within the LeBreton Flats redevelopment. This innovative approach eliminates the need for fossil fuels, aligning with Ottawa's commitment to reducing greenhouse gas emissions and promoting clean energy solutions across the province, including the Hydrogen Innovation Fund that supports new low-carbon pathways.

The system operates by diverting sewage from the municipal collection network into an external well, where it undergoes filtration to remove large solids. The filtered water is then passed through a heat exchanger, transferring thermal energy to the building's heating and cooling systems. After the energy is extracted, the treated water is safely returned to the city's sewer system.

Environmental and Economic Impact

Once fully implemented, the SEES is projected to deliver over 9 megawatts of heating and cooling capacity, servicing approximately 2.4 million square feet of development. This capacity is expected to reduce greenhouse gas emissions by approximately 5,066 tonnes annually—equivalent to the electricity consumption of over 3,300 homes for a year. Such reductions are pivotal in helping Ottawa meet its ambitious goal of achieving a 96% reduction in community-wide greenhouse gas emissions by 2040, as outlined in its Climate Change Master Plan and Energy Evolution strategy, and they align with Ontario's plan to rely on battery storage to meet rising demand across the grid.

Integration with the Odenak Development

The first phase of the SEES will support the Odenak development, a mixed-use project comprising two high-rise residential buildings. This development is poised to be Canada's largest residential zero-carbon project, echoing calls for Northern Ontario grid sustainability from community groups, featuring 601 housing units, with 41% designated as affordable housing. The integration of the SEES will ensure that Odenak operates entirely on renewable energy, setting a benchmark for future urban developments.

Broader Implications and Future Expansion

The SEES project is not just a localized initiative; it represents a scalable model for sustainable urban energy solutions that aligns with green energy investments in British Columbia and other jurisdictions. The LeBreton Community Utility Partnership is in discussions with the National Capital Commission to explore extending the SEES network to additional parcels within the LeBreton Flats redevelopment. Expanding the system could lead to economies of scale, further reducing costs and enhancing the environmental benefits.

Ottawa's venture into wastewater-based energy systems places it at the forefront of a growing trend in North America. Cities like Toronto and Vancouver have initiated similar projects, while related pilots such as the EV-to-grid pilot in Nova Scotia highlight complementary approaches, and European counterparts have long utilized sewage heat recovery systems. Ottawa's adoption of this technology underscores its commitment to innovation and sustainability in urban planning.

The SEES project at LeBreton Flats exemplifies how cities can repurpose existing infrastructure to create sustainable, low-carbon energy solutions. By transforming wastewater into a valuable energy resource, Ottawa is setting a precedent for environmentally responsible urban development. As the city moves forward with this initiative, it not only addresses immediate energy needs but also contributes to a cleaner, more sustainable future for its residents, even as the province accelerates Ontario's energy storage push to maintain reliability.

Sierra Club: Governor Abbott's Demands Would Leave Texas More Polluted and Texans in the Dark

Texas Energy Policy Debate centers on ERCOT and PUC directives, fossil fuels vs renewables, grid reliability, energy efficiency, battery storage, and blackout risks, shaping Texas power market rules, conservation alerts, and capacity planning.

 

Key Points

Policy fight over ERCOT/PUC rules weighing fossil fuels vs renewables and storage to bolster Texas grid reliability.

✅ ERCOT and PUC directives under political scrutiny

✅ Fossil fuel subsidies vs renewable incentives and storage

✅ Focus on grid reliability, efficiency, and blackout prevention

 

Earlier this week, Governor Abbott released a letter to the Public Utility Commission of Texas (PUC) and the Electric Reliability Council of Texas (ERCOT), demanding electricity market reforms that Abbott falsely claims will "increase power generation capacity and to ensure the reliability of the Texas power grid."

Unfortunately, Abbott's letter promotes polluting, unreliable fossil fuels, attacks safer clean energy options, and ignores solutions that would actually benefit everyday Texans.

"Governor Abbott, in a blatant effort to politicize Texans' energy security, wants to double down on fossil fuels, even though they were the single largest point of failure during both February's blackouts and June's energy conservation alerts," said Cyrus Reed, Interim Director & Conservation Director of the Lone Star Chapter of the Sierra Club.

"Many of these so-called solutions were considered and rejected most recently by the Texas Legislature. Texas must focus on expanding clean and reliable renewable energy, energy efficiency, and storage capacity, as voters consider funding to modernize generation in the months ahead.

"We can little afford to repeat the same mistakes that have failed to provide enough electricity where it is needed most and cost Texans billions of dollars. Instead of advocating for evidence-based solutions, Abbott wants to be a culture warrior for coal and gas, even as he touts grid readiness amid election season, even when it results in blackouts across Texas."

Energy UK - Switching surge continues

UK Energy Switching Surge sees 600,000 customers change suppliers in October, driven by competition, the Energy Switch Guarantee, and better tariffs, with Electralink's DTN supporting customer switching and Ofgem oversight.

 

Key Points

A rise in UK customers switching electricity suppliers in October, driven by competition and the Energy Switch Guarantee.

✅ 600,000 switches recorded in October

✅ 32% moved to small and mid-tier suppliers

✅ Energy Switch Guarantee assures simple, safe transfers

 

More than 600,000 customers took steps to save on their energy bills this winter by switching electricity provider in October, as forecasts such as a 16% bill decrease in April offer further encouragement, the latest figures from Energy UK reveal.

A third (32 per cent) of those changing providers in October moved to small and mid-tier suppliers.

Regional markets have seen changes too, including Irish electricity price increases that highlight wider cost pressures.

With recent research showing that that nine in ten energy switchers were happy with the process of changing suppliers and with the reassurance provided by the Energy Switch Guarantee - a series of commitments ensuring switches are simple, speedy and safe - and amid MPs proposing price restrictions to protect consumers, more and more customers are now confident when looking to move.

Lawrence Slade, chief executive of Energy UK said: 'Switching continues to surge with over 600,000 customers changing supplier to find a better deal last month. Many more will have made savings by checking they are on the best deal with their current supplier. It only takes a few minutes to do this and with over 55 suppliers across the market, there's never been more competition or choice.'

Around 75 per cent of the market are signatories of the Guarantee. This includes: British Gas, Bulb Energy, E.ON, EDF Energy, First Utility, Flow Energy, npower, Octopus Energy, Pure Planet, Sainsbury's Energy, Scottish Power, So Energy and Tonik Energy.

The switching data is supplied by Electralink who provides a secure service to transfer data between the electricity market participants. The company operates the Data Transfer Network (DTN) which underpins customer switching, meter interoperability and other business processes critical to a competitive electricity market, where knowing where your electricity comes from can support informed choices.

The data referenced in these reports is since our collection of data only and is for electricity only.

These figures do not include internal electricity switching, and statistics on this from the larger suppliers and on Standard Variable Tariffs can be viewed on the Ofgem website, while ministers consider ending the gas-electricity price link to reduce bills.

Maritime Link sends first electricity between Newfoundland, Nova Scotia

Maritime Link HVDC Transmission connects Newfoundland and Nova Scotia to the North American grid, enabling renewable energy imports, subsea cable interconnection, Muskrat Falls hydro power delivery, and lower carbon emissions across Atlantic Canada.

 

Key Points

A 500 MW HVDC intertie linking Newfoundland and Nova Scotia to deliver Muskrat Falls hydro power.

✅ 500 MW capacity using twin 170 km subsea HVDC cables

✅ Interconnects Newfoundland and Nova Scotia to the North American grid

✅ Enables Muskrat Falls hydro imports, cutting CO2 and costs

 

For the first time, electricity has been sent between Newfoundland and Nova Scotia through the new Maritime Link.

The 500-megawatt transmission line — which connects Newfoundland to the North American energy grid for the first time and echoes projects like the New England Clean Power Link underway — was tested Friday.

"This changes not only the energy options for Newfoundland and Labrador but also for Nova Scotia and Atlantic Canada," said Rick Janega, the CEO of Emera Newfoundland and Labrador, which owns the link.

"It's an historic event in our eyes, one that transforms the electricity system in our region forever."

 

'On time and on budget'

It will eventually carry power from the Muskrat Falls hydro project in Labrador, where construction is running two years behind schedule and $4 billion over budget, a context in which the Manitoba Hydro line to Minnesota has also faced delay, to Nova Scotia consumers. It was supposed to start producing power later this year, but the new deadline is 2020 at the earliest.

The project includes two 170-kilometre subsea cables across the Cabot Strait between Cape Ray in southwestern Newfoundland and Point Aconi in Cape Breton.

The two cables, each the width of a two-litre pop bottle, can carry 250 megawatts of high voltage direct current, and rest on the ocean floor at depths up to 470 metres.

This reel of cable arrived in St. John's back in April aboard the Norwegian vessel Nexans Skagerrak, after the first power cable reached Nova Scotia earlier in the project. (Submitted by Emera NL)

The Maritime Link also includes almost 50 kilometres of overland transmission in Nova Scotia and more than 300 kilometres of overland transmission in Newfoundland, paralleling milestones on Site C transmission work in British Columbia.

The link won't go into commercial operation until January 1.

Janega said the $1.6-billion project is on time and on budget.

"We're very pleased to be in a position to be able to say that after seven years of working on this. It's quite an accomplishment," he said.

Once in service, the link will improve electrical interconnections between the Atlantic provinces, aligning with climate adaptation guidance for Canadian utilities.

"For Nova Scotia it will allow it to achieve its 40 per cent renewable energy target in 2020. For Newfoundland it will allow them to shut off the Holyrood generating station, in fact using the Maritime Link in advance of the balance of the project coming into service," Janega said.

Karen Hutt, president and CEO of Nova Scotia Power, which is owned by Emera Inc., calls it a great day for Nova Scotia.

"When it goes into operation in January, the Maritime Link will benefit Nova Scotia Power customers by creating a more stable and secure system, helping reduce carbon emissions, and enabling NSP to purchase power from new sources," Hutt said in a statement.

Electricity blackouts spark protests in Iranian cities

Iran Power Outage Protests surge as electricity blackouts, drought, and a looming heat wave spark unrest in Tehran, Shiraz, and more, with chants against leadership, strikes, and sanctions-driven economic pressures mounting.

 

Key Points

Protests across Iran over blackouts, drought, and economic strain challenge authorities and demand accountability.

✅ Rolling blackouts blamed on drought, heat wave, and surging demand.

✅ Chants target leadership amid strikes and wage, water shortages.

✅ Legitimacy questioned after low-turnout election and sanctions.

 

There have been protests in a number of cities in Iran amid rising public anger over widespread electricity blackouts.

Videos on social media appeared to show crowds in Shar-e Rey near Tehran, Shiraz, Amol and elsewhere overnight.

Some people can be heard shouting "Death to the dictator" and "Death to Khamenei" - a reference to Supreme Leader Ayatollah Ali Khamenei.

The government has apologised for the blackouts, which it has blamed on a severe drought and high demand.

Elsewhere, similar outages have had political repercussions, as a widespread power outage in Taiwan prompted a minister's resignation earlier this year.

President Hassan Rouhani explained in televised remarks on Tuesday morning that the drought meant most of the country's hydroelectric power plants were not operating, placing more pressure on thermal power plants, and that electricity consumption had surged as people used air conditioning to cope with the intense summer heat.

"I apologise to our dear people who have faced problems and suffering in the past few days and I urge them to co-operate [by cutting their electricity use]. People complain about power outages and they are right," Mr Rouhani said.

A video that has gone viral in recent days shows a woman complaining about the blackouts and corruption at a government office in the northern city of Gorgan and demanding that her comments be conveyed to "higher-ups like Mr Rouhani". "The only thing you have done is forcing hijab on us," she shouts.

The president has promised that the government will seek to resolve the problems within the next two or three weeks.

However, a power sector spokesman warned on Monday that consumption was exceeding the production capacity of Iran's power plants by 11GW, and said a "looming heat wave" could make the situation worse, as seen in Iraq's summer electricity crunch this year.

Iranians have also been complaining about water shortages and the non-payment of wages by some local authorities, while thousands of people working in Iran's oil industry have been on strike over pay and conditions, as officials discuss further energy cooperation with Iraq to ease supply pressures.

There was already widespread discontent at government corruption and the economic hardship caused by sanctions that were reinstated when the US abandoned a nuclear deal with Iran three years ago, even as Iran supplies about 40% of Iraq's electricity through cross-border sales.

Analysts say that after the historically low turnout in last month's presidential election, when more than half of the eligible voters stayed at home, the government is facing a serious challenge to its legitimacy.

Mr Rouhani will be succeeded next month by Ebrahim Raisi, a hard-line cleric close to Ayatollah Khamenei who won 62% of the vote after several prominent contenders were disqualified, while Iran finalizes power grid deals with Iraq to bolster regional ties.

The 60-year-old former judiciary chief has presented himself as the best person to combat corruption and solve Iran's economic problems, including ambitions to transmit electricity to Europe as a regional power hub.

But many Iranians and human rights activists have pointed to his human rights record, accusing him of playing a role in the executions of thousands of political prisoners in the 1980s and in the deadly crackdowns on mass anti-government protests in 2009 and 2019.

Pennsylvania Home to the First 100% Solar, Marriott-Branded U.S. Hotel

Courtyard by Marriott Lancaster Solar Array delivers 100% renewable electricity via photovoltaic panels at Greenfield Corporate Center, Pennsylvania, a High Hotels and Marriott sustainability initiative reducing grid demand and selling excess power for efficient operations.

 

Key Points

A $1.5M PV installation powering the 133-room hotel with 100% renewable electricity in Greenfield Center, Lancaster.

✅ 2,700 PV panels generate 1,239,000 kWh annually

✅ First Marriott in the US with 100% solar electricity

✅ $504,900 CFA grant; excess power sold to the utility

 

High Hotels Ltd., a hotel developer and operator, recently announced it is installing a $1.5 million solar array that will generate 100% of the electrical power required to operate one of its existing hotels in Greenfield Corporate Center. The completed installation will make the 133-room Courtyard by Marriott-Lancaster the first Marriott-branded hotel in the United States with 100% of its electricity needs generated from solar power. It is also believed to be the first solar array in the country installed for the sole purpose of generating 100% of the electricity needs of a hotel, mirroring how other firms are commissioning their first solar power plant to meet sustainability goals.

“This is an exciting approach to addressing our energy needs that aligns very well with High’s commitment to environmental stewardship,”

“We’ve been advancing many environmentally responsible practices across our hotel portfolio, including converting the interior and exterior lighting at the Lancaster Courtyard to LED, which will lower electricity demand by 15%,” said Russ Urban, president of High Hotels. “Installing solar is another important step in this progression, and we will look to apply lessons from this as we expand our portfolio of premium select-service hotels.”

The Lancaster-based hotel developer, owner and operator is working in partnership with Marriott International Inc. to realize this vision, in step with major brands announcing new clean energy projects across their portfolios.

The installation of more than 2,700 ballasted photovoltaic panels will fill an area more than two football fields in size. After evaluating several on-site and near-site alternatives, High Hotels decided to install the solar array on the roof of a nearby building in Greenfield Corporate Center. Using the existing roof saves more than three acres of open land and has additional aesthetic benefits, aligning with recommendations for solar farms under consideration by local planners. The solar array will produce 1,239,000 kWh of power for the hotel, which consumes 1,177,000 kWh. Any excess power will be sold to the utility, though affordable solar batteries are making on-site storage increasingly feasible.

High Hotels received a grant of $504,900 from the Commonwealth Financing Authority (CFA) through the Solar Energy Program to complete the project. An independent agency of the Department of Community and Economic Development (DCED), the CFA is responsible for evaluating projects and awarding funds for a variety of economic development programs, including the Solar Energy Program and statewide initiatives like solar-power subscriptions that broaden access. The project will receive a solar renewable energy credit which will be conveyed to the CFA to provide the agency with more funds to offer grants in the future.

“This is a cutting-edge project that is exactly the kind we are looking for to promote the generation and use of solar energy,” said DCED Secretary Dennis Davin. “I am very pleased that the first Marriott in the US to receive 100% of its electric needs through renewable solar energy is located right here in Central Pennsylvania.” Secretary Davin also serves as chairman of the CFA’s board.

Panels for the solar array will be Q Cells manufactured by Hanwha Cells Co., Ltd., headquartered in Seoul, South Korea. Ephrata, Pa.-based Meadow Valley Electric Inc. will install the array in the second and third quarters of 2018 with commissioning targeted for September 2018.
