Rhode Island issues its plan to achieve 100% renewable electricity by 2030

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.

DOE LNG Export Approvals expand flexibility for Cheniere's Sabine Pass and Corpus Christi to ship to non-FTA countries, boosting U.S. supply to Europe while advancing methane emissions reductions and strengthening global energy security.

Key Points

DOE LNG export approvals authorize Sabine Pass and Corpus Christi to sell full-capacity LNG to non-FTA markets.

✅ Exports allowed to any non-FTA country, including Europe

✅ Capacity covers Sabine Pass and Corpus Christi terminals

✅ DOE targets methane reductions across oil and gas

The U.S. Department of Energy (DOE) today issued two long-term orders authorizing liquefied natural gas (LNG) exports from two current operating LNG export projects, Cheniere Energy Inc.’s Sabine Pass in Louisiana and Corpus Christi in Texas, following a recent deep freeze that slammed the American energy sector.

The two orders allow Sabine Pass and Corpus Christi additional flexibility to export the equivalent of 0.72 billion cubic feet per day of natural gas as LNG to any country with which the U.S. does not have a free trade agreement, including all of Europe, such as the UK natural gas market as well.

While U.S. exporters are already exporting at or near their maximum capacity, with today's issuances, every operating U.S. LNG export project has approval from DOE to export its full capacity to any country where not prohibited by U.S. law or policy constraints in place.

The U.S. is now the top global exporter of LNG and exports are set to grow an additional 20% beyond current levels by the end of this year as additional capacity comes online, even as a domestic energy crisis influences electricity and gas markets.  In January 2022, U.S. LNG supplied more than half of the LNG imports into Europe for the month.

With the expected rise in LNG exports, DOE is particularly focused on driving down methane emissions in the oil and gas sector both domestically and abroad, leveraging the deep technical expertise of the Department, and supporting nuclear innovation as well.

U.S. LNG remains an important component to global energy security worldwide and DOE remains committed to finding ways to help our allies and trading partners, including support to Ukraine and others with the energy supplies they need while continuing to work to mitigate the impact of climate change.

Condo EV charging retrofits face strata approval thresholds, installation costs, and limited electrical capacity, but government rebates, subsidies, and smart billing systems can improve ROI, property value, and feasibility amid electrician shortages and infrastructure constraints.

Key Points

Condo EV charging retrofits equip multiunit parking with EV chargers, balancing costs, bylaws, capacity, and rebates.

✅ Requires owner approval (e.g., 75% in B.C.) and clear bylaws

✅ Leverage rebates, subsidies, and load management to cut costs

✅ Plan billing, capacity, and phased installation to increase ROI

Retrofitting an existing multiunit residential building with electric vehicle charging stations is a complex and costly exercise, as high-rise EV charging challenges in MURBs demonstrate, even after subsidies, but the biggest hurdle to adoption may be getting enough condo owners on board.

British Columbia, for example, offers a range of provincial government subsidies to help condo corporations (referred to in B.C. as stratas) with everything from the initial research to installing the chargers. But according to provincial strata law, three-quarters of owners must support the plan before it is implemented, though new strata EV legislation could make approvals easier in some jurisdictions.

“The largest challenge is getting that 75-per-cent majority approval to go ahead,” says EV charging specialist Patrick Breuer with ChargeFwd Ltd., a Vancouver-based sustainable transport consultancy.

Chris Brunner, a strata president in Vancouver, recently upgraded all the building’s parking stalls for EV charging. His biggest challenge was getting the strata’s investment owners, who don’t live in the building and were not interested in spending money, to support the project.

“We had to sell it in two ways,” Mr. Brunner says. “First, that there’s going to be a return on investment, including vehicle-to-building benefits that support savings and grid stability, and second, that there will come a time when this will be required. And if we do it now, taking advantage of the generous rebates and avoiding price increases for expertise and materials, we’ll be ahead of the curve.”

Once the owners have voted in favour, the condo board can begin the planning process and start looking for rebates. The B.C. government will provide a rebate of up to 75 per cent for the consulting phase, with additional provincial rebates available through current programs. It’s referred to as an “EV Ready” plan, which is a professionally prepared document that describes how to implement EV charging fairly, and estimates its cost.

Once a condo has completed the EV Ready plan, it becomes eligible for other rebates, such as the EV Ready Infrastructure subsidy, which will bring power to each individual parking stall through an energized outlet. This is rebated at 50 per cent of expenses, up to $600 a stall.

There are further rebates of up to 75 per cent for installing the charging stations themselves, and B.C. charging rebates extend to home and workplace programs, too. The program is administered by BC Hydro, a Crown corporation that receives funding in annual increments. “Right now, it’s funded until March 31, 2023,” Mr. Breuer says.

“Realtors are valuing [individual charging stations] from $2,000 to $10,000,” he said. The demand for installing EV chargers in buildings has grown to such an extent that it’s hard to find qualified electricians, Mr. Breuer says.

However, even with subsidies, there are some buildings where it doesn’t make financial sense to retrofit them. “If you have to core through thin floors or there’s a big parkade with a large voltage drop, it isn’t financially viable,” Mr. Breuer says. “We do a lot of EV Ready plans, but not all the projects can go ahead.”

For many people, it’s resistance to the unknown that is preventing them from voting for the retrofit, according to Carter Li of Toronto-based Swtch Energy Inc., which provides charging in high-density urban settings. It has done retrofits on 200 multiunit residential buildings in the Toronto area, and Calgary condo charging efforts show similar momentum in other cities, too. “They’re worried about paying for someone else’s electricity,” he says. Selling owners on the idea requires educating them about how the billing will work, maximizing electrical capacity to keep costs down, using government subsidies and the anticipated boost in property value.

Ontario currently does not provide any subsidies for retrofitting condos for EV charging. However, there is a stipulation under the Condominium Act that if owners request EV charging be installed and provide a condo board with sufficient documentation, an assessment will be conducted.

When Jeremy Benning was on the board of his Toronto condo in 2018, a few residents inquired about installing EV charging. A committee of owners did the legwork, and found a company that could do the infrastructure installation as well as set up accounts for individual billing purposes. Residents were surveyed a number of times before going ahead with the installation.

Mr. Benning estimates it cost about $40,000 to install two electrical subpanels to accommodate EV chargers in 20 parking spaces. Although the condo corporation paid the money up front out of its operating budget, everyone who ordered a charger will pay back their share over time. Many who do not even own an EV have opted to add a valuable frill to their unit.

The board considered applying for a subsidy from Natural Resources Canada, but it would require a public charger in the visitor parking lot. “The rebate wasn’t enough to pay for the cost of putting in that charging station,” Mr. Benning says. “Also, you have to maintain it, and what if it gets vandalized? It wasn’t worth it.”

Quebec’s Roulez Vert (Ride Green) program offers extensive provincial rebates and incentives for retrofitting condo buildings. If a single condo owner wants to install an EV charger, the government will refund up to 50 per cent of the installation cost or up to $5,000, whichever is less.

Otherwise, a property manager can qualify for a maximum of $25,000 a year to retrofit a building and can sometimes complete the work in stages. “They may do the first installation in one year, and then continue the next year,” says Léo Viger-Bernard of Recharge Véhicule Électrique (RVE). Recently, the Quebec government confirmed this program will run until 2027.

RVE consults with condo corporations, operates an online platform (murby.com) with resources for building owners, and sells a demand charge controller (DCC), which is an electric vehicle energy management system. The DCC allows an electrician to plug the EV charger directly into the electrical infrastructure of a single condo or apartment unit. Not only does this reduce extra wiring, but it also monitors the electrical consumption in each unit, only powering the charging station when there’s available electricity. Billing is assigned to the actual unit’s electricity bill.

Currently there are about 12,000 DCC units installed in retrofitted buildings across Canada, some that are 40 or 50 years old. “It’s not a question of age; it’s more the location of the electric meters,” Mr. Viger-Bernard says. The DCC can be installed either on the roof or on different floors.

According to Michael Wilk, president of Montreal-based Wilkar Property Management Inc., the biggest barrier is getting condo owners to understand the necessity of doing a retrofit now, as opposed to waiting. He uses price increases to try to convince them.

“Right now, the cost of doing a retrofit is 35 per cent more than it was two years ago,” he says. “If you wait another two years, we can only anticipate it’s going to be 35 per cent higher because of the rising cost of labour, parts and equipment.”

In Nova Scotia, Marc MacDonald of Spark Power Corp. installed an EV charger with a DCC unit at a condo near Halifax about a year ago. “They only had space in their electrical room to add a device for up to 10 EV chargers,” he says. The condo board was hesitant, demanding a great deal of information. “They were concerned about everyone wanting an EV charger.”

Now that Nova Scotia has introduced a program for rebates and incentives to install EV chargers in condos, on-street sites and more, Mr. MacDonald anticipates demand will increase, though Atlantic EV adoption still lags the national average. “But they’ll have to settle with reality. Not everyone can have an EV charger if the building can’t accommodate it.”

California Iron-Air Battery Storage Project delivers 100-hour long-duration energy storage, supported by a $30 CEC grant, using Form Energy technology at a PG&E substation to boost grid reliability, integrate renewables, and cut fossil reliance.

Key Points

California's 5 MW/500 MWh iron-air battery delivers 100-hour discharge, boosting reliability and renewable integration.

✅ 5 MW/500 MWh iron-air system at a PG&E substation

✅ 100-hour multiday storage enhances grid reliability

✅ CEC $30M grant backs non-lithium, long-duration tech

The California Energy Commission (CEC) has given the green light to a $30 million grant to Form Energy for the construction of an extraordinary long-duration energy storage project that will offer an unparalleled 100 hours of continuous grid discharge.

This ambitious endeavor involves the development of a 5-megawatt (MW) / 500 megawatt-hour iron-air battery storage project, representing the largest long-duration energy storage initiative in California. It also marks the state's inaugural utilization of this cost-effective technology, and joins ongoing procurements by utilities such as San Diego Gas & Electric to expand storage capacity statewide. The project's location is set at a substation owned by the Pacific Gas and Electric Company in Mendocino County, where it will supply power to local residents. The system is scheduled to commence operation by the conclusion of 2025, contributing to grid reliability and showcasing solutions aligned with the state's climate and clean energy objectives.

CEC Chair David Hochschild commented, "A multiday battery system is transformational for California's energy mix. This project will enhance our ability to harness excess renewables during nonpeak hours for use during peak demand, especially as we work toward a goal of 100 percent clean electricity."

This grant award represents one of three approvals within the framework of the CEC's Long-Duration Energy Storage program, a part of Governor Gavin Newsom's historic multi-billion-dollar commitment to combat climate change. This program fosters investment in the demonstration of non-lithium-ion technologies across the state, including green hydrogen microgrids, contributing to the creation of a diverse portfolio of energy storage technologies.

As of August, California had 6,600 MW of battery storage actively deployed statewide, a trend mirrored in regions like Ontario as well, operating within the prevailing industry standard of 4 to 6 hours of discharge. By year-end, this figure is projected to expand to 8,600 MW. Longer-duration storage, spanning from 8 to 100 hours, holds the potential to expedite the state's shift away from fossil fuels while reinforcing grid stability. California estimates that more than 48 gigawatts (GW) of battery storage and 4 GW of long-duration storage will be requisite to achieve the objective of 100 percent clean electricity by 2045.

Energy storage serves as a cornerstone of California's clean energy future, offering a means to capture and store surplus power generated by renewable resources, including emerging virtual power plant models that aggregate distributed assets. The state's battery infrastructure plays a pivotal role during the summer when electricity demand peaks in the early evening hours as solar resources decline, preceding the later surge in wind energy.

Iron-air battery technology operates on the principle of reversible rusting. These battery cells contain iron and air electrodes and are filled with a water-based, nonflammable electrolyte solution. During discharge, the battery absorbs oxygen from the air, converting iron metal into rust. During the charging phase, the application of an electrical current converts the rust back into iron, releasing oxygen. This technology is cost-competitive compared to lithium-ion battery production and complements broader clean energy BESS initiatives seen in New York.

Canada Coal Phase-Out Costs highlight Fraser Institute findings on renewable energy, wind and solar integration, grid reliability, natural gas backup, GDP impacts, greenhouse gas emissions reductions, nuclear alternatives, and transmission upgrades across provincial electricity systems.

Key Points

Costs to replace coal with renewables, impacting taxpayers and ratepayers while ensuring grid reliability.

✅ Fraser Institute estimates $16.8B-$33.7B annually for renewables.

✅ Emissions cut from coal phase-out estimated at only 7.4% nationally.

✅ Natural gas backup and grid upgrades drive major cost increases.

Replacing coal-fired electricity with renewable energy will cost Canadian taxpayers and hydro ratepayers up to $33.7 billion annually, with only minor reductions in global greenhouse gas emissions linked to climate change, according to a new study by the Fraser Institute.

The report, Canadian Climate Policy and its Implications for Electricity Grids by University of Victoria economics professor G. Cornelis van Kooten, said replacing coal-fired electricity with wind and solar power would only cut Canada’s annual emissions by 7.4%,

Prime Minister Justin Trudeau’s has promised a reduction of 40%-45% compared to Canada’s 2005 emissions by 2030, and progress toward the 2035 clean electricity goals remains uncertain.

The study says emission cuts would be relatively small because coal accounted for only 9.2% of Canada’s electricity generation in 2017. (According to Natural Resources Canada, that number is lower today at 7.4%).

In 2019, the last year for which federal data are available, Canada’s electricity sector generated 8.4% of emissions nationally — 61.1 million tonnes out of 730 million tonnes.

“Despite what advocates, claim, renewable power — including wind and solar — isn’t free and, as Europe's power crisis lessons suggest, comes with only modest benefits to the environment,” van Kooten said.

“Policy makers should be realistic about the costs of reducing greenhouse gas emissions in Canada, which accounts for less than 2% of emissions worldwide.”

The report says the increased costs of operating the electricity grid across Canada — between $16.8 billion and $33.7 billion annually or 1% to 2% of Canada’s annual GDP — would result from having to retain natural gas, consistent with net-zero regulations allowing some natural gas in limited cases, as a backup to intermittent wind and solar power, which cannot provide baseload power to the electricity grid on demand.

Van Kooten said his cost estimates are conservative because his study “could not account for scenarios where the scale of intermittency turned out worse than indicated in our dataset … the costs associated with the value of land in other alternative uses, the need for added transmission lines, as analyses of greening Ontario's grid costs indicate, environmental and human health costs and the life-cycle costs of using intermittent renewable sources of energy, including costs related to the disposal of hazardous wastes from solar panels and wind turbines.”

If nuclear power was used to replace coal-fired electricity, the study says, costs would drop by half — $8.3 billion to $16.7 billion annually — but that’s unrealistic because of the time it takes to build nuclear plants and public opposition to them.

The study says to achieve the federal government’s target of reducing emissions to 40% to 45% below 2005 levels by 2030 and net-zero emissions by 2050, would require building 30 nuclear power plants before 2030, highlighting Canada’s looming power problem as described by analysts — meaning one plant of 1,000-megawatt capacity coming online every four months between now and 2030.

Alternatively, it would take 28,340 wind turbines, each with 2.5-megawatts capacity, or 1,050 turbines being built every four months, plus the costs of upgrading transmission infrastructure.

Van Kooten said he based his calculations on Alberta, which generates 39.8% of its electricity from coal and the cost of Ontario eliminating coal-fired electricity, even as Ontario electricity getting dirtier in coming years, which generated 25% of its electricity, between 2003 and 2014, replacing it with a combination of natural gas, nuclear and wind and solar power.

According to Natural Resources Canada, Nova Scotia generates 49.9% of its electricity from coal, Saskatchewan 42.9%, and New Brunswick 17.2%.

In 2018, the Trudeau government announced plans to phase-out traditional coal-fired electricity by 2030, though the Stop the Shock campaign seeks to bring back coal power in some regions. 

Canada and the U.K. created the “Powering Past Coal Alliance” in 2017, aimed at getting other countries to phase out the use of coal to generate electricity.

Oxford Battery Energy Storage Project will store surplus renewable power near South-West Oxford and Woodstock, improving grid stability, peak shaving, and reliability, pending IESO approval and Hydro One transmission interconnection in Ontario.

Key Points

A Boralex battery project in South-West Oxford storing surplus power for Woodstock at peak demand pending IESO approval.

✅ 2028 commercial operation target

✅ Connects to Hydro One transmission line

✅ Peak shaving to stabilize grid costs

A Quebec-based renewable energy company is proposing to build a battery energy storage system in Oxford County near Woodstock.

The Oxford battery energy storage project put forward by Boralex Inc., if granted approval, would be ready for commercial operation in 2028. The facility would be in the Township of South-West Oxford, but also would serve Woodstock businesses and residences, supported by provincial disconnect moratoriums for customers, due to the city’s proximity to the site.

Battery storage systems charge when energy sources produce more energy than customers need, and, complementing Ontario’s energy-efficiency programs across the province, discharge during peak demand to provide a reliable, steady supply of energy.

Darren Suarez, Boralex’s vice-president of public affairs and communications in North America, said, “The system we’re talking about is a very large battery that will help at times when the electric grid has too much energy on the system. We’ll be able to charge our batteries, and when there’s a need, we can discharge the batteries to match the needs of the electric grid.”

South-West Oxford is a region Boralex has pinpointed for a battery storage project. “We look at grid needs as a whole, and where there is a need for battery storage, and we’ve identified this location as being a real positive for the grid, to help with its stability, a priority underscored by the province’s nuclear alert investigation and public safety focus,” Suarez said.

Suarez could not provide an estimated cost for the proposed facility but said the project would add about 75 jobs during the construction phase, in a sector where the OPG credit rating remains stable. Once the site is operational, only one or two employees will be necessary to maintain the facility, he said.

Boralex requires approval from the Independent Electricity System Operator (IESO), the corporation that co-ordinates and integrates Ontario’s electricity system operations across the province, for the Oxford battery energy storage project.

Upon approval, the project will connect with an existing Hydro One transmission line located north of the proposed site. “[Hydro One] has a process to review the project and review the location and ensure we are following safety standards and protocols in terms of integrating the project into the grid, with broader policy considerations like Ottawa’s hydro heritage also in view, but they are not directly involved in the development of the project itself,” Suarez said.

The proposal has been presented to South-West Oxford council. South-West Oxford Mayor David Mayberry said, “(Council) is still waiting to see what permits are necessary to be addressed if the proposal moves forward.”

Mayberry said the Ministry of Natural Resources and Forestry also would be reviewing the proposed project.

Thornton Sand and Gravel, the location of the proposed facility, was viewed positively by Mayberry. “From a positive perspective, they’re not using farmland. There is a plus we’re not using farmland, but there is concern something could leak into the aquifer. These questions need to be answered before it can be to the satisfaction of the community,” Mayberry said.

An open house was held on Sept. 14 to provide information to residents. Suarez said about 50 people showed up and the response was positive. “Many people came out to see what we planned for the project and there was a lot of support for the location because of where it actually is, and how it integrates into the community. It’s considered good use of the land by many of the people that were able to join us on that day,” Suarez said.

The Quebec-based energy company has been operating in Ontario for nearly 15 years and has wind farms in the Niagara and Chatham-Kent regions.

Boralex also is involved in two other battery storage projects in Ontario. The Hagersville project is a 40-minute drive northwest of Hamilton, and the other is in Tilbury, a community in Chatham-Kent. Commercial operation for both sites is planned to begin in 2025.

South-West Oxford and Woodstock will see some financial benefits from the energy storage system, Suarez said.

“It will help to stabilize energy costs. It will contribute to really shaving the most expensive energy on the system off the system. They’re going to take electricity when it’s the least costly, taking advantage of Ontario’s ultra-low overnight pricing options and utilize that least costly energy and displace the most costly energy.”
