Canadian long-term energy storage company Hydrostor is partnering with Kiewit on a FEED study for a massive energy storage centre in California.
It would be capable of eliminating the equivalent of roughly 120,000 cars off the road every year.
The facility would use Hydrostor’s advanced compressed air technology to store excess green energy.
The Whole Story:
The 500 MW Willow Rock Energy Storage Center would be the largest stand-alone energy storage project in the state. It also comes after California officials have set a goal of using 100 per cent carbon-free energy by 2045.
The project will store excess generation from California solar and wind projects during periods of low customer demand by compressing air and storing it on the project site. During periods of higher customer demand or low supply, this high-pressure air is used to generate emissions-free electricity to meet real-time electrical load and enhance overall grid reliability. The project is designed to generate electricity for at least eight hours at full capacity.
Hydrostor stated that the work demonstrates steady progress in the development of its advanced compressed air energy storage (A-CAES) technology in North America.
According to Hydrostor, A-CAES uses commercially proven equipment and processes to provide affordable, large-scale, and emission- free long-duration energy storage (LDES).
The company added that Willow Rock will be capable of storing enough energy to provide reliable power for up to 400,000 homes over 8 hours, turning California’s growing solar and wind resources into on-demand peaking capacity, enabling the closure of emitting fossil fuel resources while maximizing transmission system utilization.
“Hydrostor continues to reach important milestones at Willow Rock, and we look forward to working with the world-class engineering and construction teams at Kiewit to advance this critical clean energy project,” said Curtis VanWalleghem, Hydrostor CEO. “Our global teams are paving the way towards achieving aggressive net-zero goals. Willow Rock will be capable of eliminating the equivalent of roughly 120,000 cars off the road every year over its 50+ year project life.”
Kiewit praised Hydrostor’s approach, stating that LDES solutions like A-CAES are a critical component of grid modernization.
“We look forward to commencing work on Willow Rock, which has the potential to abate significant emissions and provide a reliable, sustainable energy source for many decades,” said Kevin Needham, president of Kiewit Power Engineers.
Key Takeaways
The first phase of the rules goes into effect this October.
More than half of the demolition material that hits Metro Vancouver landfills is recyclable.
Starting in 2023, the rules will be encouraged with a deposit system that gives a refund when the diversion goal is hit.
The Whole Story:
Rules around demolition waste are changing for Burnaby, B.C.
The city is introducing the Construction & Demolition Waste Diversion Bylaw, which mandates that at least 70 per cent of waste created as a result of building demolitions must be diverted from landfills.
City officials stated that once the bylaw comes into force in fall of this year, it will represent a major step in Burnaby’s efforts to meet Metro Vancouver’s regional goal of 80 per cent overall waste diversion.
“As materials from construction and demolition make up a third of Metro Vancouver’s solid waste, making improvements in the sector is an integral part of the City’s overall waste reduction strategy,” said the city. “More than half of the approximately 400,000 tonnes of demolition material which flows into Metro Vancouver landfills annually is recyclable, and diverting resources like wood, metal and concrete to recycling facilities is a vital step in reducing the greenhouse gases these materials emit when not disposed of correctly.”
Officials explained that the new bylaw will be introduced in phases, with multi-family and non-residential demolitions subject to the new regulations on October 1, 2022, and rules for single- and two-family buildings coming into force on March 1, 2023.
After these dates, demolitions will require a non-refundable application fee of $250, and a deposit of $2.25 per square foot of the building being demolished, with a maximum deposit cap of $50,000. The refund received will be calculated on the percentage of waste diverted to the proper recycling channels, with the entire deposit amount being refunded for demolitions which divert 70 per cent or more of their waste.
The funding will help groups like the Heiltsuk First Nation from Bella Bella. The Nation will use the funds for an essential road infrastructure project designed to increase access to the community by linking Bella Bella to the airport.
The project includes converting the existing road into a dedicated pedestrian and bike path and constructing 2 km of new road.
The Stswecem’c Xget’tem First Nation also received funding. The plan to gain greater food build two green houses, two walk-in freezers and a canning shed, which will support the community garden and sustainability program. Officials say these developments will help safeguard against the impact on food production caused by environmental threats.
In the Strathcona Regional District funds will be used to give residents better and safer access to Read Island through the reconstruction of a dock, boardwalk and community building.
Other communities across the province, including Cumberland, Salt Spring Island, Spallumcheen, and Sparwood will benefit from new or upgraded wastewater treatment facilities and drinking water systems, including the rehabilitation of an aging dam, construction of a new well and reservoir, and upgrades to sewage treatment facilities.

Evolve is looking to be one of the most energy-efficient multi-family residential buildings in Canada. The school stated that it will give researchers a unique opportunity to study the benefits and trade-offs of passive house construction, and share the results with the entire industry.
“This is a rarity in Canadian urban development – to have similar-sized mid-rise comparator buildings, constructed by the same developers, on the same grounds, with the same property manager, similar tenancy profiles, and the same investment in research infrastructure,” added Rysanek. “This is an incredible chance for us to evaluate the benefits and potential trade-offs between Passive House and typical construction in terms of tenant experience, costs and building systems data concerning air quality, noise, extreme heat tolerance, energy consumption and carbon emissions.”
Evolve’s passive house design elements include:
High performance windows – triple glazed “tilt and turn” windows that significantly increase natural ventilation rates over typical residential buildings in B.C.
High-efficiency mechanical system – heat recovery ventilation system continuously providing filtered air.
Thermal insulation – a thicker insulation and assembly was required to create a thermal barrier
Building envelope continuity – elimination of cold patches or drafts. The design and construction both account for less air leakage through the structure and the building envelope.
Mixed-mode cooling – ventilation air provided throughout the building is cooled via an energy-efficient heat pump, but sensors on operable windows and patio doors ensure maximum cool air is only supplied to residential suites when their windows are closed– the ventilation will reduce to a minimum but will not fully turn off.
Exterior shading – movable shades to limit heat and exposure of the sun.
Work on the six-storey, 103,000-square foot building began in 2020. Residents began moving in to studio, one, two, three and four-bedroom units in mid-August.
Key Takeaways:
Niverville, Taché, Hanover and Ritchot in Manitoba will benefit from the new facility.
The mechanical treatment facility will allow these cities to shift away from less efficient methods.
Project work includes installing roughly 90 kilometres of effluent pipeline.
The Whole Story:
Officials announced more than $39 million in funding will go towards the construction of a regional mechanical wastewater treatment facility and collection network to service four communities in southeastern Manitoba.
The Red-Seine-Rat (RSR) Wastewater Treatment Facility & Conveyance System will provide the municipalities of Niverville, Taché, Hanover and Ritchot with a new regional wastewater treatment facility to help keep up with current and future population demands.
The work will include the installation of a wastewater conveyance system with approximately 90 kilometres of effluent pipeline as well as new lift stations and pump stations.
Officials say the facility will increase the region’s capacity to treat and manage wastewater and stormwater, improve the environmental stewardship of the region and encourage economic growth.
They added that it will also result in greenhouse gas reductions as regional partners are able to move away from traditional wastewater lagoons to a new mechanical wastewater treatment facility.
Ottawa will contribute $21.6 million to the project through the Green Infrastructure Stream of the Investing in Canada Infrastructure Program. The province plans to invest over $18 million and the contribution from the proponent is more than $70.2 million.
“Manitoba is home to some of the largest freshwater bodies in the world, and today, we are acting on our collective responsibility to safeguard their health,” said Terry Duguid, minister of the environment and climate change. “By investing in this novel wastewater treatment infrastructure, we are creating better environmental, economic and social outcomes for all Manitobans. This project is another example of what can be accomplished when all levels of government work together.”

Edmonton plans to build Canada’s largest solar array.
It’s expected to create up to $460,000 in savings each year.
The array is part of a larger, $98-million upgrade at the centre
The Whole Story:
The Edmonton Expo Centre will soon be home to the largest rooftop solar array in Canada. Phase 1 of the $5.03 million project will see 5,754 solar panels installed across 193,735.5 square feet.
“The City of Edmonton is committed to becoming an energy sustainable and climate resilient city,” said program manager Brad Watson. “This rooftop solar panel array will generate at least 2.8 gigawatts of energy annually, equal to that of about 375 homes.”
Based on the design energy models the array is anticipated to yield operational savings in the realm of $290,000 to $460,000 per year.
“Our new rooftop solar installation means that we will be producing our own renewable, clean solar energy right here on top of our building,” said Melissa Radu, director of social & environmental sustainability with Explore Edmonton. “It also acts as a reminder, to Edmontonians and visitors to our city, that Edmonton is a leader for innovative energy technologies in our country and that we are working hard to support a transition to a lower-carbon economy.”
Officials explained that while other buildings in the city have solar arrays or are having arrays built, the Edmonton EXPO Centre presented a unique opportunity to go bigger.
“The Edmonton EXPO Centre is a unicorn of sorts when it comes to rooftop solar panels,” said Watson. “Its size and dimensions, unobstructed sightlines and lack of interfering rooftop infrastructure allowed us to build an array of this size.”
City officials say the solar system is expected to last 25 years and will yield a payback between 10 to 17 years, considering energy prices and whether energy consumption aligns with generation.
If approved, phase 2 will see additional panels installed across Halls A through C, increasing the footprint of this project as well as significant cost savings. Phase 2 will add a production of approximately 1.9 gigawatts to the system and the estimated cost is roughly $3.4 million. Phase 2 would add an additional saving of about $185,000 to $300,000 per year.
Phase 1 is expected to wrap up in November.
This project is one of 11 solar projects currently underway in Edmonton. Six solar arrays in Edmonton are in operation.
This solar installation is part of a $98 million rehabilitation project at the Edmonton EXPO Centre. On top of the solar project, crews will upgrade seating in Hall D and updates to Entrance 6 on the north side of the building. Improvements are also being made to the building envelope, and mechanical and electrical systems, including major equipment replacements in the mechanical and electrical rooms. The Edmonton EXPO Centre will remain open during work.

Key Takeaways:
By 2025, new buildings in Victoria, B.C. must be zero carbon.
This is part of larger plans to be completely on renewable energy by 2050.
The move would make it one of the first B.C. cities to have a zero carbon construction standard.
The Whole Story:
Starting in 2025 Victoria will require all new construction to be zero carbon. The city noted that the new goal is part is of its accelerated climate action plan to cut greenhouse gas emissions by 50 per cent before 2050.
The requirement will come on the heels of the the BC Building Code carbon pollution standards that start this year.
The zero carbon standard is five years ahead of B.C.’s carbon requirements. The city stated that the new requirements are expected to significantly cut greenhouse gas emissions from new buildings. By 2050 the city plans to also switch over to 100 per cent renewable energy. The switch could trip up to 7 per cent of the total community emissions needed to reach those 2050 goals.

The city boasted that it is one of the first municipalities to establish a zero carbon polluting standard for construction and steer away from fossil fuels for water and space heating.
The requirements and schedule were set after an engagement process with the local building industry, co-led by the city of Victoria, the district of Saanich and the district of Central Saanich with support from the Capital Regional District (CRD). The engagement focused on how best to reduce greenhouse gas emissions from new construction through the BC Energy Step Code and the forthcoming carbon pollution standards.
According to a report by the Global Alliance for Buildings and Construction, buildings were responsible for 38 per cent of global carbon emissions in 2020. This was followed by the transportation industry, which contributed 23 per cent of emissions. The report accounted for emissions produced during construction as well as operation, including natural gas heating or coal-powered electricity.
