Solar Is Now 33% Cheaper Than Gas Power in US, Guggenheim Says

Nova Scotia Biomass Electricity Policy increases dispatchable renewable generation from Port Hawkesbury and Brooklyn Energy, raising MWh output while critics cite clearcutting, carbon emissions, high costs to ratepayers, and delays replacing Muskrat Falls hydro.

Key Points

Policy directing utilities to maximize biomass power as dispatchable renewable supply during hydro delays.

✅ Port Hawkesbury biomass output up 35% year over year

✅ Brooklyn Energy used as dispatchable renewable supply

✅ Critics cite clearcutting, emissions, high ratepayer costs

A boiler owned by Nova Scotia Power on the grounds of the Port Hawkesbury paper plant, whose discount power rate request has drawn attention, is burning 35% more woody biomass this year than last. 

The year-to-date figures show 126,810 megawatt hours (MWh) of electricity was generated over the first nine months of 2021 compared to 93,934 MWh for the same period in 2020 and 65,891 MWh in 2019. 

The information is contained in monthly fuel cost reports Nova Scotia Power must make to the Utility and Review Board, which regulates how much consumers ultimately pay for electricity and has received a call for major grid changes in Nova Scotia.

Burning biomass  — which includes everything from low-grade pulpwood to bark, shavings, and wood chip waste from sawmills — for the purpose of generating electricity is only about 22% efficient, even as some coal stations have switched to biomass abroad. Nova Scotia Power’s boiler at Port Hawkesbury supplies about 3% of the total electricity used in the province. 

Citizens concerned about climate change have for years opposed the government classifying biomass as “renewable energy” and have echoed calls to reduce biomass use for electricity, because clearcutting, which releases carbon from the ground, remains the dominant form of harvesting on Crown and private land. That’s despite ongoing work to begin implementing 2018 recommendations from Professor Bill Lahey to move toward a more ecological approach. 

In May 2020, after it became obvious renewable hydroelectricity from Muskrat Falls was going to be delayed yet again, the McNeil government passed an Order-in-Council extending until December 2022 the deadline to generate 40% of electricity from renewable sources as it moved to increase wind and solar projects across Nova Scotia. 

To help with the shortfall, Nova Scotia Power was told to “maximize” its use of biomass at both the facility it owns in Port Hawkesbury and another one in Brooklyn owned by its parent company, Emera.

In a letter to Nova Scotia Power dated May 15, then-Energy Minister Derek Mombourquette, amid debate over independent energy planning, added: “Nova Scotia Power shall also maximize the use of dispatchable renewable electricity from its own facilities, as well as those of renewable electricity power producers in Nova Scotia (excluding COMFIT generation sources).” 

By definition, “dispatchable” excludes wind and hydro sources, which are not available 24/7, though a new attempt to harness the Bay of Fundy's tides is underway. Nova Scotia Power claims the only “dispatchable renewable electricity power producer” in the province is Brooklyn Energy, the 35 MW biomass plant near Liverpool. 

The government capped at $7 million a year how much electricity Nova Scotia Power could buy from its affiliate company. Critics of the deal — such as auditors hired by the regulator and the province’s consumer advocate — say electricity generated by Brooklyn is the most expensive power and question why the province would burden ratepayers with its purchase.

The answer became apparent in September 2020 when then-Intergovernmental Affairs Minister Kelliann Dean appeared before the legislature’s standing committee on Natural Resources and Economic Development to praise the Order-in-Council for helping rescue the forestry industry four months after the closure of the Northern Pulp mill. 

“The change to Renewable Energy Standards (May,2020) is enabling Nova Scotia Power to generate more electricity from wood chips and sawmill residuals by operating two biomass plants at capacity until electricity from Muskrat Falls comes onstream,” she said. “We are using all the policy levers at our disposal to support the sector.”

Nova Scotia Power is not required to report to the UARB how much electricity is being produced or how much biomass is being burned at Brooklyn Energy. The company pleads “commercial confidentiality” when asked by The Halifax Examiner. 

Nova Scotia Power does report how much it spends each month to buy power from independent producers — a small group which includes Brooklyn but excludes all wind farms. That dollar amount has also increased over the past year — from $15.9 million for 10 months ending October 2020 compared to $23.3 million for 10 months ending October 2021. Unfortunately, the lack of transparency makes it impossible to know exactly how much of that increase is attributable to purchasing more biomass.

Radio silence
The current Minister of Natural Resources and Renewable Energy ,Tory Rushton, has the authority to reduce the amount of biomass being burned to generate electricity and by extension, the rate of clearcutting.

With a stroke of the pen, the PC government of Tim Houston could issue another Order-in-Council capping the amount of metric tonnes that could be used in the boilers, or, direct Nova Scotia Power to use biomass only when it is the most economical fuel choice. 

But so far, Rushton has not responded to the Halifax Examiner’s question about whether he intends to make any change to stop “maximizing” the use of biomass to produce electricity.

 The Examiner isn’t the only one pushing the Minister for answers to difficult issues. At noon today, Citizens opposed to a controversial clearcut on Crown land near Rocky Point Lake in Digby County will stage a demonstration outside the Department of Natural Resources and Renewable Energy on Hollis Street. The protest led by members of Extinction Rebellion and the Healthy Forest Coalition is to pressure the government to take action to protect the habitat of the mainland moose, an endangered species that ranges overs the Crown land currently being cut by the Westfor consortium.

O2 Tidal Turbine delivers tidal energy in Orkney, Scotland, supplying grid-connected renewable power via EMEC and enabling green hydrogen production, providing clean electricity with predictable generation from strong coastal currents.

Key Points

A 2 MW, grid-connected tidal device in Orkney that delivers clean power and enables EMEC green hydrogen production.

✅ 2 MW capacity; powers ~2,000 UK homes via EMEC grid

✅ Predictable renewable output from strong coastal currents

✅ Enables onshore electrolyzer to produce green hydrogen

“The world’s most powerful” tidal turbine has been hooked up to the onshore electricity grid in Orkney, a northerly archipelago in Scotland, and is ready to provide homes with clean, green electricity, even as a major UK offshore windfarm begins supplying power this week.

The tidal turbine, known as the O2, was developed by Scottish engineering firm Orbital Marine Power. On July 28, they announced O2 “commenced grid connected power generation” at the European Marine Energy Centre (EMEC) in Orkney, meaning it's all set up and providing energy to the local power grid, similar to another Scottish tidal project that recently powered nearly 4,000 homes.

The 74-meter-long (242-foot) turbine is said to be “the world’s most powerful” tidal turbine. It will lay in the waters off Orkney for the next 15 years with the capacity to meet the annual electricity demand of around 2,000 UK homes. The 2MW turbine is also set to power the EMEC’s land-based electrolyzer that will generate green hydrogen (hydrogen made without fossil fuels) that can also be used as a clean energy source, in a UK energy system that recently set a wind generation record for output.

“Our vision is that this project is the trigger to the harnessing of tidal stream resources around the world and, alongside investment in UK offshore wind, to play a role in tackling climate change whilst creating a new, low-carbon industrial sector,” Orbital CEO, Andrew Scott, said in a press release.

Tidal energy is harnessed by converting energy from the natural rise and fall of ocean tides and currents. The O2 turbine consists of two submerged blades with a 20-meter (65-foot) diameter attached to a turbine that will move with the shifting currents of Orkney’s coast to generate electricity. Electricity is then transferred from the turbine along the seabed via cables towards the local onshore electricity network, a setup also being used by a Nova Scotia tidal project to supply the grid today.

This method of harnessing energy is not just desirable because it doesn't release carbon emissions, but it’s more predictable than other renewable energy sources, such as solar or Scotland's wind farms that can be influenced by weather conditions. Tidal energy production is still in its infancy and there are relatively few large-scale tidal power plants in the world, but many argue that some parts of the world could potentially draw huge benefits from this innovative form of hydropower, especially coastal regions with strong currents such as the northern stretches of the UK and the Bay of Fundy in Atlantic Canada.

The largest tidal power operation in the world is the Sihwa Lake project on the west coast of South Korea, which harnesses enough power to support the domestic needs of a city with a population of 500,000 people. However, once fully operational, the MeyGen tidal power project in northern Scotland hopes to snatch its title.

EVI-Pro Lite EV Load Forecasting helps utilities model EV charging infrastructure, grid load shapes, and resilient energy systems, factoring home, workplace, and public charging behavior to inform planning, capacity upgrades, and flexible demand strategies.

Key Points

A NREL tool projecting EV charging demand and load shapes to help utilities plan the grid and right-size infrastructure.

✅ Visualizes weekday/weekend EV load by charger type.

✅ Tests home, workplace, and public charging access scenarios.

✅ Supports utility planning, demand flexibility, and capacity upgrades.

As electric vehicles (EVs) continue to grow in popularity, utilities and community planners are increasingly focused on building resilient energy systems that can support the added electric load from EV charging, including a possible EV-driven demand increase across the grid.

But forecasting the best ways to adapt to increased EV charging can be a difficult task as EV adoption will challenge state power grids in diverse ways. Planners need to consider when consumers charge, how fast they charge, and where they charge, among other factors.

To support that effort, researchers at the National Renewable Energy Laboratory (NREL) have expanded the Electric Vehicle Infrastructure Projection (EVI-Pro) Lite tool with more analytic capabilities. EVI-Pro Lite is a simplified version of EVI-Pro, the more complex, original version of the tool developed by NREL and the California Energy Commission to inform detailed infrastructure requirements to support a growing EV fleet in California, where EVs bolster grid stability through coordinated planning.

EVI-Pro Lite’s estimated weekday electric load by charger type for El Paso, Texas, assuming a fleet of 10,000 plug-in electric vehicles, an average of 35 daily miles traveled, and 50% access to home charging, among other variables, as well as potential roles for vehicle-to-grid power in future scenarios. The order of the legend items matches the order of the series stacked in the chart.

Previously, the tool was limited to letting users estimate how many chargers and what kind of chargers a city, region, or state may need to support an influx of EVs. In the added online application, those same users can take it a step further to predict how that added EV charging will impact electricity demand, or load shapes, in their area at any given time and inform grid coordination for EV flexibility strategies.

“EV charging is going to look different across the country, depending on the prevalence of EVs, access to home charging, and the kind of chargers most used,” said Eric Wood, an NREL researcher who led model development. “Our expansion gives stakeholders—especially small- to medium-size electric utilities and co-ops—an easy way to analyze key factors for developing a flexible energy strategy that can respond to what’s happening on the ground.”

Tools to forecast EV loads have existed for some time, but Wood said that EVI-Pro Lite appeals to a wider audience, including planners tracking EVs' impact on utilities in many markets. The tool is a user-friendly, free online application that displays a clear graphic of daily projected electric loads from EV charging for regions across the country.

After selecting a U.S. metropolitan area and entering the number of EVs in the light-duty fleet, users can change a range of variables to see how they affect electricity demand on a typical weekday or weekend. Reducing access to home charging by half, for example, results in higher electric loads earlier in the day, although energy storage and mobile charging can help moderate peaks in some cases. That is because under such a scenario, EV owners might rely more on public or workplace charging instead of plugging in at home later in the evening or at night.

“Our goal with the lite version of EVI-Pro is to make estimating loads across thousands of scenarios fast and intuitive,” Wood said. “And if utilities or stakeholders want to take that analysis even deeper, our team at NREL can fill that gap through partnership agreements, too. The full version of EVI-Pro can be tailored to develop detailed studies for individual planners, agencies, or utilities.”

British Columbia Green Infrastructure Funding expands CleanBC Communities Fund projects, from EV charging stations to sewage heat recovery, delivering low-carbon heat in Vancouver and supporting Indigenous communities and COVID-19 recovery through the Green Infrastructure Stream.

Key Points

A joint federal-provincial program backing CleanBC to fund EV chargers, sewage heat recovery, and low-carbon heat.

✅ Funds EV charging across Vancouver Island and northern B.C.

✅ Expands sewage heat recovery via Vancouver's NEU

✅ Joint federal, provincial, local, and Indigenous partners

The governments of Canada and British Columbia are investing in infrastructure to get projects under way that meet people's needs, address the effects of the COVID-19 pandemic, and help communities restart their economies.  

Strategic investments in green infrastructure are key to creating clean healthy communities, making life more affordable, and building a clean electricity future for Canada.

Today, the Honourable Jonathan Wilkinson, Minister of Environment and Climate Change and Member of Parliament for North Vancouver, on behalf of the Honourable Catherine McKenna, Minister of Infrastructure and Communities, and the Honourable George Heyman, B.C. Minister of Environment and Climate Change Strategy, announced funding for 11 projects, alongside initiatives like the province's hydrogen project, to help B.C. communities save energy and reduce pollution.  

In Vancouver, the Sewage Heat Recovery Expansion Project will increase the capacity of the Neighbourhood Energy Utility (NEU) to provide buildings in the False Creek area with low-carbon heat and hot water. The NEU recycles waste heat and uses a mix of renewable and conventional natural gas to reduce harmful emissions.

Funding is also going towards expanding the network of Level-2 electric vehicle (EV) charging stations across the province. More than 80 new stations will be installed in communities across mid-Vancouver Island, as well as northern and central B.C., making clean transportation options, supported by incentives for zero-emission vehicles, more viable for more people.

These, along with the other projects announced today, will create jobs and strengthen local economies now while promoting sustainable growth and residents' long-term health and well-being.

The Government of Canada is investing more than $28.5 million in these projects through the Green Infrastructure Stream (GIS) of the Investing in Canada plan, and local and Indigenous communities are contributing more than $13 million. The Government of British Columbia is contributing nearly $18 million through the CleanBC Communities Fund, part of the federal Investing in Canada plan's Green Infrastructure Stream, which also supports rebates for home and workplace charging initiatives.

First Glasgow Electric Buses will transform the Caledonia depot with 160 charging points, zero-emission operations, grid upgrades, and rapid charging, supported by Transport Scotland funding and Alexander Dennis manufacturing for cleaner urban routes by 2023.

Key Points

Electric single-deckers at Caledonia depot with 160 chargers and upgrades, delivering zero-emission service by 2023

✅ 160 charging points; 4-hour rapid recharge capability

✅ Grid upgrades to power a fleet equal to a 10,000-person town

✅ Supported by Transport Scotland; built by Alexander Dennis

First Bus will install 160 charging points and replace half its fleet with electric buses at its Caledonia depot in Glasgow.

The programme is expected to be completed in 2023, similar to Metro Vancouver's battery-electric rollout milestones, with the first 22 buses arriving by autumn.

Charging the full fleet will use the same electricity as it takes to power a town of 10,000 people.

The scale of the project means changes are needed to the power grid, a challenge highlighted in global e-bus adoption analysis, to accommodate the extra demand.

First Glasgow managing director Andrew Jarvis told BBC Scotland: "We've got to play our part in society in changing how we all live and work. A big part of that is emissions from vehicles.

"Transport is stubbornly high in terms of emissions and bus companies need to play their part, and are playing their part, in that zero emission journey."

First Bus currently operates 337 buses out of its largest depot with another four sites across Glasgow.

The new buses will be built by Alexander Dennis at its manufacturing sites in Falkirk and Scarborough.

The transition requires a £35.6m investment by First with electric buses costing almost double the £225,000 bill for a single decker running on diesel.

But the company says maintenance and running costs, as seen in St. Albert's electric fleet results, are then much lower.

The buses can run on urban routes for 16 hours, similar to Edmonton's first e-bus performance, and be rapidly recharged in just four hours.

This is a big investment which the company wouldn't be able to achieve on its own.

Government grants only cover 75% of the difference between the price of a diesel and an electric bus, similar to support for B.C. electric school buses programmes, so it's still a good bit more expensive for them.

But they know they have to do it as a social responsibility, and large-scale initiatives like US school bus conversions show the direction of travel, and because the requirements for using Low Emissions Zones are likely to become stricter.

The SNP manifesto committed to electrifying half of Scotland's 4,000 or so buses within two years.

Some are questioning whether that's even achievable in the timescale, though TTC's large e-bus fleet offers lessons, given the electricity grid changes that would be necessary for charging.

But it's a commitment that environmental groups will certainly hold them to.

Transport Scotland is providing £28.1m of funding to First Bus as part of the Scottish government's commitment to electrify half of Scotland's buses in the first two years of the parliamentary term.

Net Zero Secretary Michael Matheson said: "It's absolute critical that we decarbonise our transport system and what we have set out are very ambitious plans of how we go about doing that.

"We've set out a target to make sure that we decarbonise as many of the bus fleets across Scotland as possible, at least half of it over the course of the next couple of years, and we'll set out our plans later on this year of how we'll drive that forward."

Transport is the single biggest source of greenhouse gas emissions in Scotland which are responsible for accelerating climate change.

In 2018 the sector was responsible for 31% of the country's net emissions.

Electric bus
First Glasgow has been trialling two electric buses since January 2020.

Driver Sally Smillie said they had gone down well with passengers because they were much quieter than diesel buses.

She added: "In the beginning it was strange for them not hearing them coming but they adapt very easily and they check now.

"It's a lot more comfortable. You're not feeling a gear change and the braking's smoother. I think they're great buses to drive."

Sicily Green Hydrogen accelerates decarbonization via renewable energy, wind farm electrolysis, hydrogen storage, and distribution from Enel Green Power and Sapio at the NextHy industrial lab in Carlentini and Sortino Sicily hub.

Key Points

Sicily Green Hydrogen is an Enel-Sapio plan to produce hydrogen via wind electrolysis for industrial decarbonization.

✅ 4 MW electrolyzer powered by Carlentini wind farm

✅ Estimated 200+ tons annual green H2 production capacity

✅ Market distribution managed by Sapio across Sicily

This green hydrogen will be produced at the Sicilian industrial plant, an innovative hub that puts technology at the service of the energy transition, echoing hydrogen innovation funds that support similar goals worldwide

Activating a supply of green hydrogen produced using renewable energy from the Carlentini wind farm in eastern Sicily is the focus of the agreement signed by Enel Green Power and Sapio. The agreement provides for the sale to Sapio of the green hydrogen that will be produced, stored in clean energy storage facilities and made available from 2023 at the Carlentini and Sortino production sites, home to Enel Green Powers futuristic NextHy innitiative. Sapio will be responsible for developing the market and handling the distribution of renewable hydrogen to the end customer.

In contexts where electrification is not easily achievable, green hydrogen is the key solution for decarbonization as it is emission-free and offers a potential future for power companies alongside promising development prospects, commented Salvatore Bernabei, CEO of Enel Green Power. For this reason we are excited about the agreement with Sapio. It is an agreement that looks to the future by combining technological innovation and sustainable production.

Sapio is strongly committed to contributing to the EUs achievement of the UN SDGs, commented Alberto Dossi, President of the Sapio Group, and with this project we are taking a firm step towards sustainable development in our country. The agreement with EGP also gives us the opportunity to integrate green hydrogen into our business model, as jurisdictions propose hydrogen-friendly electricity rates to grow the hydrogen economy, which is based on our strong technological expertise in hydrogen and its distribution over 100 years in business. In this way we will also be able to give further support to the industrial activities we are already carrying out in Sicily.

The estimated 200+ tons of production capacity of the Sicilian hub is the subject of the annual supply foreseen in the agreement. Once fully operational, the green hydrogen will be produced mainly by a 4 MW electrolyzer, which is powered exclusively by the renewable energy of the existing wind farm, and to a lesser extent by the state-of-the-art electrolysis systems tested in the platform. Launched by Enel Green Power in September 2021, NextHys Hydrogen Industrial Lab is a unique example of an industrial laboratory in which production activity is constantly accompanied by technological research. In addition to the sectors reserved for full-scale production, there are also areas dedicated to testing new electrolyzers, components such as valves and compressors, and innovative storage solutions based on liquid and solid means of storage: in line with Enels open-ended approach, this activity will be open to the collaboration of more than 25 entities including partners, stakeholders and innovative startups. The entire complex is currently undergoing an environmental impact assessment at the Sicily Regions Department of Land and Environment.

It is an ambitious project with a sustainable energy source at its heart that will be developed at every link in the chain: thanks to the agreement with Sapio, in fact, at NextHy green hydrogen will now not only be produced, stored and moved on an industrial scale, but also purchased and used by companies that have understood that green hydrogen is the solution for decarbonizing their production processes. In this context, this experimental approach that is open to external contributions will allow the Enel Green Power laboratory team to test the project on an industrial scale, so as to create the best conditions for a commercial environment that can make the most of all present and future technologies for the generation, storage and transport of green hydrogen, including green hydrogen microgrids that demonstrate scalable integration. It is an initiative consistent with Enels Open Innovability spirit: meeting the challenges of the energy transition by focusing on innovation, ideas and their transformation into reality.
