The Knoxville Convention Center is going green.

The downtown facility will be installing the first of two solar panel systems on its roof to generate renewable energy for the area. An inverter power pack and chiller for the 30 kilowatt solar panel system will be lowered by helicopter onto the roof.

Convention Center spokesman Jason Bourgoyne said the solar power system will be tied into the TVA-KUB power network and also will meet part of the Convention Center's electricity needs.

The building, which cost $93 million to construct, houses a 30,000-square-foot ballroom that can seat 1,900 people, 120,000 square feet of exhibit space, 13 meeting rooms and a 460-seat lecture hall. It opened in 2002.

BC Hydro activates "winter payment plan"

BC Hydro Winter Payment Plan lets customers spread electricity bills over six months during cold weather, easing costs amid colder-than-average temperatures in British Columbia, with low-income conservation support, energy-saving kits, and insulation upgrades.

 

Key Points

Allows BC Hydro customers to spread winter electricity bills over six months, with added low-income efficiency support.

✅ Spread Dec-Mar bills across six months

✅ Eases costs during colder-than-average temperatures

✅ Includes low-income conservation and energy-saving kits

 

As colder temperatures set in across the province again this weekend, BC Hydro says it is activating its winter payment plan to give customers the opportunity to spread out their electricity bills as demand can reach record levels during extreme cold periods.

"Our meteorologists are predicting colder-than-average temperatures will continue over the next of couple of months and we want to provide customers with help to manage their payments," said Chris O'Riley, BC Hydro's president.

All BC Hydro customers will be able to spread payments from the billing period spanning Dec. 1, 2017 to March 31, 2018 over a six-month period.

Cold weather in the second half of December 2017 led to surging electricity demand that was higher than the previous 10-year average and has at times hit all-time highs during peak usage periods, according to BC Hydro.

Hydro operations also respond to summer conditions, as drought and low rainfall can force adjustments in power generation strategies.

People who heat their homes with electricity — about 40 per cent of British Columbians —  have the highest overall bills in the province, $197 more in December than in July, when air conditioning use can affect energy costs.

This is the second year the Crown corporation has activated a cold-weather payment plan, part of broader customer assistance programs it offers.  

BC Hydro has also increased funding for its low-income conservation programs by $2.2 million for a total of $10 million over the next three years. 

The low-income program provides energy-saving kits that include things like free energy assessments, insulation upgrades and weather stripping.

The ferries will be 100 feet (approximately 30 meters) in length, with a beam of 26 feet and a draft of 5.9 feet. Each vessel will be powered by dual 625-kilowatt electric motors, enabling them to achieve speeds of up to 24 knots. The vessels will be built to U.S. Coast Guard Subchapter T standards, ensuring compliance with stringent safety regulations.

Environmental and Operational Benefits

The transition to battery-electric propulsion offers numerous environmental and operational advantages. Electric ferries produce zero emissions during operation, as demonstrated by Berlin's electric ferry deployments, significantly reducing the carbon footprint of maritime transport. Additionally, electric propulsion systems are generally more efficient and require less maintenance compared to traditional diesel engines, leading to lower operational costs over the vessel's lifespan.

Broader Implications for Maritime Decarbonization

This project is part of a broader movement toward sustainable maritime transport in the United States. San Francisco Bay Ferry has also approved the purchase of two larger 400-passenger battery-electric ferries for transbay routes, further expanding its commitment to zero-emission operations. The agency has secured approximately $200 million in funding from local, state, and federal sources, echoing infrastructure bank support seen in B.C., to support these initiatives, including vessel construction and terminal electrification.

Wartsila’s involvement in this project highlights the company's leadership in the maritime industry's transition to sustainable energy solutions, including hybrid-electric pathways like BC Ferries' new hybrids now in service. With a proven track record in supplying integrated systems for zero-emission vessels, Wärtsilä is well-positioned to support the global shift toward decarbonized maritime transport.

As the first fully battery-electric high-speed passenger ferries in the United States, these vessels represent a significant milestone in the journey toward sustainable and environmentally responsible maritime transportation, paralleling regional advances such as the Kootenay Lake electric-ready ferry entering service. The collaboration between Wärtsilä, All American Marine, and San Francisco Bay Ferry exemplifies the collective effort required to realize a zero-emission future for the maritime industry.

The deployment of these battery-electric ferries in San Francisco Bay not only advances the city's environmental objectives but also sets a precedent for other regions to follow. With continued innovation and collaboration, the maritime industry can look forward to a future where sustainable practices are the standard, not the exception.

Ireland and France will connect their electricity grids - here's how

Celtic Interconnector, a subsea electricity link between Ireland and France, connects EU grids via a high-voltage submarine cable, boosting security of supply, renewable integration, and cross-border trade with 700 MW capacity by 2026.

 

Key Points

A 700 MW subsea link between Ireland and France, boosting security, enabling trade, and supporting renewables.

✅ Approx. 600 km subsea cable from East Cork to Brittany

✅ 700 MW capacity; powers about 450,000 homes

✅ Financed by EIB, banks, CEF; Siemens Energy and Nexans

 

France and Ireland signed contracts on Friday to advance the Celtic Interconnector, a subsea electricity link to allow the exchange of electricity between the two EU countries. It will be the first interconnector between continental Europe and Ireland, as similar UK interconnector plans move forward in parallel. 

Representatives for Ireland’s electricity grid operator EirGrid and France’s grid operator RTE signed financial and technical agreements for the high-voltage submarine cable, mirroring developments like Maine’s approved transmission line in North America for cross-border power. The countries’ respective energy ministers witnessed the signing.

European commissioner for energy Kadri Simson said:

In the current energy market situation, marked by electricity price volatility, and the need to move away from imports of Russian fossil fuels, European energy infrastructure has become more important than ever.

The Celtic Interconnector is of paramount importance as it will end Ireland’s isolation from the Union’s power system, with parallels to Cyprus joining the electricity highway in the region, and ensure a reliable high-capacity link improving the security of electricity supply and supporting the development of renewables in both Ireland and France.

EirGrid and RTE signed €800 million ($827 million) worth of financing agreements with Barclays, BNP Paribas, Danske Bank, and the European Investment Bank, similar to the Lake Erie Connector investment that blends public and private capital.

In 2019, the project was awarded a Connecting Europe Facility (CEF) grant worth €530.7 million to support construction works and align with a broader push for electrification in Europe under climate strategies. The CEF program also provided €8.3 million for the Celtic Interconnector’s feasibility study and initial design and pre-consultation.

Siemens Energy will build converter stations in both countries, and Paris-based global cable company Nexans will design and install a 575-km-long cable for the project.

The cable will run between East Cork, on Ireland’s southern coast, and northwestern France’s Brittany coast and will connect into substations at Knockraha in Ireland and La Martyre in France.

The Celtic Interconnector, which is expected to be operational by 2026, will be approximately 600 km (373 miles) long and have a capacity of 700 MW, similar to cross-border initiatives such as Quebec-to-New York power exports expected in 2025, which is enough to power 450,000 households.

Ontario Supports Plan to Safely Continue Operating the Pickering Nuclear Generating Station

Pickering Nuclear Generating Station Refurbishment will enable OPG to deliver reliable, clean electricity in Ontario, cut CO2 emissions, support jobs, boost Cobalt-60 medical isotopes supply, and proceed under CNSC oversight alongside small modular reactor leadership.

 

Key Points

A plan to assess and renew Pickering's B units, extending safe, clean, low-cost power in Ontario for up to 30 years.

✅ Extends zero-emissions baseload by up to 30 years

✅ Requires CNSC approval and rigorous safety oversight

✅ Supports Ontario jobs and Cobalt-60 isotope production

 

The Ontario government is supporting Ontario Power Generation’s (OPG) continued safe operation of the Pickering Nuclear Generating Station. At the Ontario government’s request, as a formal extension request deadline approaches, OPG reviewed their operational plans and concluded that the facility could continue to safely generate electricity.

“Keeping Pickering safely operating will provide clean, low-cost, and reliable electricity to support the incredible economic growth and new jobs we’re seeing, while building a healthier Ontario for everyone,” said Todd Smith, Minister of Energy. “Nuclear power has been the safe and reliable backbone of Ontario’s electricity system since the 1970s and our government is working to secure that legacy for the future. Our leadership on Small Modular Reactors and consideration of a refurbishment of Pickering Nuclear Generating Station are critical steps on that path.”

Maintaining operations of Pickering Nuclear Generation Station will also protect good-paying jobs for thousands of workers in the region and across the province. OPG, which reported 2016 financial results that provide context for its operations, employs approximately 4,500 staff to support ongoing operation at its Pickering Nuclear Generating Station. In total, there are about 7,500 jobs across Ontario related to the Pickering Nuclear Generating Station.

Further operation of Pickering Nuclear Generating Station beyond September 2026 would require a complete refurbishment. The last feasibility study was conducted between 2006 and 2009. With significant economic growth and increasing electrification of industry and transportation, and a growing electricity supply gap across the province, Ontario has asked OPG to update its feasibility assessment for refurbishing Pickering “B” units at the Nuclear Generating Station, based on the latest information, as a prudent due diligence measure to support future electricity planning decisions. Refurbishment of Pickering Nuclear Generating Station could result in an additional 30 years of reliable, clean and zero-emissions electricity from the facility.

“Pickering Nuclear Generating Station has never been stronger in terms of both safety and performance,” said Ken Hartwick, OPG President and CEO. “Due to ongoing investments and the efforts of highly skilled and dedicated employees, Pickering can continue to safely and reliably produce the clean electricity Ontarians need.”

Keeping Pickering Nuclear Generating Station operational would ensure Ontario has reliable, clean, and low-cost energy, even as planning for clean energy when Pickering closes continues across the system, while reducing CO2 emissions by 2.1 megatonnes in 2026. This represents an approximate 20 per cent reduction in projected emissions from the electricity sector in that year, which is the equivalent of taking up to 643,000 cars off the road annually. It would also increase North America’s supply of Cobalt-60, a medical isotope used in cancer treatments and medical equipment sterilization, by about 10 to 20 per cent.

OPG requires approval from the Canadian Nuclear Safety Commission (CNSC) for its revised schedule. The CNSC, which employs a rigorous and transparent decision-making process, will make the final decision regarding Pickering’s safe operating life, even though the station was slated to close as planned earlier. OPG will continue to ensure the safety of the Pickering facility through rigorous monitoring, inspections, and testing.
