Wave energy could catch up with commercially more advanced offshore wind power within five years, the head of pioneers Aquamarine Power Ltd told Reuters.

"What it took 25 years to do in the wind industry, we want to do in five years," Chief Executive Officer Martin McAdam said in an interview.

"What we feel is we can offer a device in future that will be competitive with offshore wind energy. By 2014 we will have a commercially available device," he said.

"Our smallest offering will be 10 megawatt. We hope we can install up to 100 MW in size from 2014."

The latter amount is enough to power about 100,000 homes.

Government adviser Carbon Trust has calculated marine energy could supply up to 20 percent of Britain's power but the technology is still at the prototype stage.

To cut Britain's greenhouse gas emissions by 80 percent from the 1990 level, the government is stepping up support for new renewable technology, including marine power.

Aquamarine Power, a privately owned company set up in 2005 with headquarters in Edinburgh, is one of the handful of British companies already testing its marine energy device in the ocean.

In April, it won the first electricity from its 0.5 MW hydroelectric wave energy converter, tested at the New and Renewable Energy Center (NaREC) in Newcastle since February.

It plans to install the device, called Oyster, in July at the European Marine Energy Center (EMEC) in Orkney, Scotland — seen at the forefront of marine renewable technology development.

"Our device is very simple. It has almost no moving parts under water," said McAdam. "That means there are very few parts that can break. It's also easy to manufacture."

The converter consists of an oscillator fitted with pistons and fixed to the seabed. Each wave moves the oscillator, pumping high pressure water via a pipeline to the shore. Conventional hydroelectric generators onshore convert it into electricity.

"The biggest challenge for wave is survivability: how the device is going to survive when you have a very big wave," McAdam said.

Aquamarine has invested about 20 million pounds ($30.18 million) in the device, which is about 18 meters wide and 12 meters tall.

"We are raising more money at the moment through private equities and venture capital," McAdam said, adding it would cost 50-60 million pounds in total to fully commercialize the technology.

Asked about the credit crunch, he said: "The environment is definitely more difficult. But I see that a lot of investors are still very interested in green technologies."

"At this early stage, we are still in high intensity research and development period. Therefore some support from the government in that area is certainly required," he said.

Ambitious clean energy target will mean lower electricity prices, modelling says

Australia Clean Energy Target drives renewables in the National Electricity Market, with RepuTex modelling and the Finkel Review showing lower wholesale prices and emissions as gas generators set prices less often under ambitious targets.

 

Key Points

Policy boosting low emissions generation to cut electricity emissions and lower wholesale prices across Australia.

✅ Ambitious targets lower wholesale prices through added generation

✅ RepuTex modelling shows renewables displace costly gas peakers

✅ Finkel Review suggests CET cuts emissions and boosts reliability

 

The more ambitious a clean energy target is, the lower Australian wholesale electricity prices will be, according to new modelling by energy analysis firm RepuTex.

The Finkel review, released last month recommended the government introduce a clean energy target (CET), which it found would cut emissions from the national electricity market and put downward pressure on both wholesale and retail prices, aligning with calls to favor consumers over generators in market design.

The Finkel review only modelled a CET that would cut emissions from the electricity sector by 28% below 2005 levels by 2030. But all available analysis has demonstrated that such a cut would not be enough to meet Australia’s overall emissions reductions made as part of the Paris agreement, which themselves were too weak to help meet the central aim of that agreement – to keep global warming to “well below 2C”.

RepuTex modelled the effect of a CET that cut emissions from the electricity sector by 28% – like that modelled in the Finkel Review – as well as one it said was consistent with 2C of global warming, which would cut emissions from electricity by 45% below 2005 levels by 2030.

It found both scenarios caused wholesale prices to drop significantly compared to doing nothing, despite IEA warnings on falling energy investment that could lead to shortages, with the more ambitious scenario resulting in lower wholesale prices between 2025 and 2030.

In the “business as usual scenario”, RepuTex found wholesale prices would hover roughly around the current price of $100 per MWh.

Under a CET that reduced electricity emissions by 28%, prices would drop to under $40 around 2023, and then rise to nearly $60 by 2030.

The more ambitious CET had a broadly similar effect on wholesale prices. But RepuTex found it would drive prices down a little slower, but then keep them down for longer, stabilising at about $40 to $50 for most of the 2020s.

It found a CET would drive prices down by incentivising more generation into the market. The more ambitious CET would further suppress prices by introducing more renewable energy, resulting in expensive gas generators less often being able to set the price of electricity in the wholesale market, a dynamic seen with UK natural gas price pressures recently.

The downward pressure of a CET on wholesale prices was more dramatic in the RepuTex report than in Finkel’s own modelling. But that was largely because, as Alan Finkel himself acknowledged, the estimates of the costs of renewable energy in the Finkel review modelling were conservative.

Speaking at the National Press Club, Finkel said: “We were conservative in our estimates of wind and large-scale solar generator prices. Indeed, in recent months the prices for wind generation have already come in lower than what we modelled.”

The RepuTex modelling also found the economics of the national electricity market no longer supported traditional baseload generation – such as coal power plants that were unable to respond flexibly to demand, with debates over power market overhauls in Alberta underscoring similar tensions – and so they would not be built without the government distorting the market.

“With a premium placed on flexible generation that can ramp up or down, baseload only generation – irrespective of how clean or dirty it is – is likely to be too inflexible to compete in Australia’s future electricity system,” the report said.

“In this context, renewable energy remains attractive to the market given it is able to deliver energy reliability, with no emissions, at low cost prices, with clean grid and battery trends in Canada informing the shift for policymakers. This affirms that renewables are a lay down misere to out-compete traditionally fossil-fuel sources in Australia for the foreseeable future.”

New Power Grid “Report Card” Reveal Dangerous Vulnerabilities

U.S. Power Grid D+ Rating underscores aging infrastructure, rising outages, cyber threats, EMP and solar flare risks, strained transmission lines, vulnerable transformers, and slow permitting, amplifying reliability concerns and resilience needs across national energy systems.

 

Key Points

ASCE's D+ grade flags aging infrastructure, rising outages, and cyber, EMP, and weather risks needing investment.

✅ Major outages rising; weather remains top disruption driver.

✅ Aging transformers, transmission lines, limited maintenance.

✅ Cybersecurity gaps via smart grid, EV charging, SCADA.

 

The U.S. power grid just received its “grade card” from the American Society of Civil Engineers (ASCE) and it barely passed.

The overall rating of our antiquated electrical system was a D+. Major power outages in the United States, including widespread blackouts, have grown from 76 in 2007 to 307 in 2011, according to the latest available statistics. The major outage figures do not take into account all of the smaller outages which routinely occur due to seasonal storms.

The American Society of Civil Engineers power grid grade card rating means the energy infrastructure is in “poor to fair condition and mostly below standard, with many elements approaching the end of their service life.” It further means a “large portion of the system exhibits significant deterioration” with a “strong risk of failure.”

Such a designation is not reassuring and validates those who purchased solar generators over the past several years.

#google#

The vulnerable state of the power grid gets very little play by mainstream media outlets. Concerns about a solar flare or an electromagnetic pulse (EMP) attack instantly sending us back to an 1800s existence are legitimate, but it may not take such an extreme act to render the power grid a useless tangle of wires. The majority of the United States’ infrastructure and public systems evaluated by the ASCE earned a “D” rating. A “C” ranking (public parks, rail and bridges) was the highest grade earned. It would take a total of $3.6 trillion in investments by 2020 to fix everything, the report card stated. To put that number in perspective, the federal government’s budget for all of 2012 was slightly more, $3.7 trillion.

“America relies on an aging electrical grid and pipeline distribution systems, some of which originated in the 1880s,” the report read. “Investment in power transmission has increased since 2005, but ongoing permitting issues, weather events, including summer blackouts that strain local systems, and limited maintenance have contributed to an increasing number of failures and power interruptions. While demand for electricity has remained level, the availability of energy in the form of electricity, natural gas, and oil will become a greater challenge after 2020 as the population increases. Although about 17,000 miles of additional high-voltage transmission lines and significant oil and gas pipelines are planned over the next five years, permitting and siting issues threaten their completion. The electric grid in the United States consists of a system of interconnected power generation, transmission facilities, and distribution facilities.”

 

Harness the power of the sun when the power goes out…

There are approximately 400,000 miles of electrical transmission lines throughout the United States, and thousands of power generating plants dot the landscape. The ASCE report card also stated that new gas-fired and renewable generation issues increase the need to add new transmission lines. Antiquated power grid equipment has reportedly prompted even more “intermittent” power outages in recent years.

The American Society of Civil Engineers accurately notes that the power grid is more vulnerable to cyber attacks than ever before, including Russian intrusions documented in recent years, and it cites the aging electrical system as the primary culprit. Although the decades-old transformers and other equipment necessary to keep power flowing around America are a major factor in the enhanced vulnerability of the power grid, moving towards a “smart grid” system is not the answer. As previously reported by Off The Grid News, smart grid systems and even electric car charging stations make the power grid more accessible to cyber hackers. During the Hack in the Box Conference in Amsterdam, HP ArcSight Product Manager Ofer Sheaf stated that electric car charging stations are in essence a computer on the street. The roadway fueling stations are linked to the power grid electrical system. If cyber hackers garner access to the power grid via the charging stations, they could stop the flow of power to a specific area or alter energy distribution levels and overload the system.

While a relatively small number of electric car charging stations exist in America now, that soon will change. Ongoing efforts by both federal and state governments to reduce our reliance on fossil fuels have resulted in grants and privately funded vehicle charging station projects. New York Governor Andrew Cuomo in April announced plans to build 360 such electrical stations in his state. A total of 3,000 car charging stations are in the works statewide and are slated for completion over the next five years.

SHIELD ActWeather-related events were the primary cause of power outages from 2007 to 2012, according to the infrastructure report card. Power grid reliability issues are emerging as the greatest threat to the electrical system, with rising attacks on substations compounding the risks. The ASCE grade card also notes that retiring and rotating in “new energy sources” is a “complex” process. Like most items we routinely purchase in our daily lives, many of the components needed to make the power grid functional are not manufactured in the United States.

The SHIELD Act is the first real piece of federal legislation in years drafted to address power grid vulnerabilities. While the single bill will not fix all of the electrical system issues, it is a big step in the right direction – if it ever makes it out of committee. Replacing aging transformers, encasing them in a high-tech version of a Faraday cage, and stockpiling extra units so instant repairs are possible would help preserve one of the nation’s most critical and life-saving pieces of infrastructure after a weather-related incident or man-made disaster.

“Geomagnetic storm environments can develop instantaneously over large geographic footprints,” solar geomagnetic researcher John Kappenman said about the fragile state of the power grid. He was quoted in an Oak Ridge National Laboratory report. “They have the ability to essentially blanket the continent with an intense threat environment and … produce significant collateral damage to critical infrastructures. In contrast to well-conceived design standards that have been successfully applied for more conventional threats, no comprehensive design criteria have ever been considered to check the impact of the geomagnetic storm environments. The design actions that have occurred over many decades have greatly escalated the dangers posed by these storm threats for this critical infrastructure.”

The power grid has morphed in size tenfold during the past 50 years. While solar flares, cyber attacks, and an EMP are perhaps the most extensive and frightening threats to the electrical system, the infrastructure could just as easily fail in large portions due to weather-related events exacerbated by climate change across regions. The power grid is basically a ticking time bomb which will spawn civil unrest, lack of food, clean water, and a multitude of fires if it does go down.

WEC Energy Group to buy 80% stake in Illinois wind farm for $345 million

WEC Energy Blooming Grove Investment underscores Midwest renewable energy growth, with Invenergy, GE turbines, and 250 MW wind power capacity, tax credits, PPAs, and utility-scale generation supplying corporate offtakers via long-term contracts.

 

Key Points

It is WEC Energy's $345M purchase of an 80% stake in Invenergy's 250 MW Blooming Grove wind farm in Illinois.

✅ 94 GE turbines; 250 MW utility-scale wind capacity

✅ Output contracted to two multinational offtakers

✅ Eligible for 100% bonus depreciation and wind tax credits

 

WEC Energy Group, the parent company of We Energies, is buying an 80% stake in a wind farm, as seen with projects like Enel's 450 MW wind farm coming online, in McLean County, Illinois, for $345 million.

The wind farm, known as the Blooming Grove Wind Farm, is being developed by Invenergy, which recently completed the largest North American wind build with GE partners, a company based in Chicago that develops wind, solar and other power projects. WEC Energy has invested in several wind farms developed by Invenergy.

With the agreement announced Monday, WEC Energy will have invested more than $1.2 billion in wind farms in the Midwest, echoing heartland investment growth across the region. The power from the wind farms is sold to other utilities or companies, as federal initiatives like DOE wind awards continue to support innovation, and the projects are separate from the investments made by WEC Energy's regulated utilities, such as We Energies, in wind power.

The project, which will consist of 94 wind turbines from General Electric, is expected to be completed this year, similar to recent project operations in the sector, and will have a capacity of 250 megawatts, WEC said in a news release.

Affiliates of two undisclosed multinational companies akin to EDF's offshore investment activity have contracted to take all of the wind farm's output.

The investment is expected to be eligible for 100% bonus depreciation and, as wind economics help illustrate key trends, the tax credits available for wind projects, WEC Energy said.

Energy minister unveils Ontario's plan to address growing energy needs

Powering Ontario's Growth accelerates clean electricity, pairing solar, wind, and hydro with energy storage, efficiency investments, and new nuclear, including SMRs, to meet rising demand and net-zero goals while addressing supply planning across the province.

 

Key Points

Ontario's clean energy plan adds renewables, storage, efficiency, and nuclear to meet rising electricity demand.

✅ Over $1B for energy-efficiency programs through 2030+

✅ Largest clean power procurement in Canadian history

✅ Mix of solar, wind, hydro, storage, nuclear, and SMRs

 

Energy Minister Todd Smith has announced a new plan that outlines the actions the government is taking to address the province's growing demand for electricity.

The government is investing over a billion dollars in "energy-efficiency programs" through 2030 and beyond, Smith said in Windsor.

Experts at Ontario's Independent Electricity System recommended the planning start early to meet demand they predict will require the province to be able to generate 88,000 megawatts (MW) in 20 years.

"That means all of our current supply ... would need to double to meet the anticipated demand by 2050," he said during the announcement.

"While we may not need to start building today, government and those in the energy sector need to start planning immediately, so we have new clean, zero emissions projects ready to go when we need them."

The project is called Powering Ontario's Growth and will advance new clean energy generation from a number of sources, including solar, hydroelectric and wind.

He said this would be the biggest acquisition of clean energy in Canada's history.

Smith made the announcement at Hydro One's Keith Transmission Station.

He said the new planned procurement of green power will pair well with recent energy storage procurements, so that power generated by solar panels, for example, can be stored and injected into the system when needed.

NDP Opposition Leader Marit Stiles said Monday's announcement lacks specifics.

"It's light on details, including key questions of cost, climate impact, waste management and financial risk," said Stiles.

"Ford's Conservatives should be playing catch-up after undermining clean energy in their first term. Instead, they're offering generalities and a vague sense of what they might do."

The Green Party criticized the move Monday afternoon, noting that clean, affordable electricity remains a key Ontario election issue today.

"Ontario is facing an energy crunch – and the Ford government is making it worse by choosing more expensive, dirtier options," said MPP for Guelph Mike Schreiner in the statement.

He said Premier Doug Ford has "grossly" mismanaged the province's energy supply by cancelling 750 renewable energy projects and slashing efficiency programs.

"Now, faced with an opportunity to become a leader in a world that's rapidly embracing renewable energy, this government has chosen to funnel taxpayer dollars into polluting fossil gas plants and expensive new nuclear that will take decades to come online," said Schreiner.

Smith announced last week the plan for three more small modular reactors at the site of the Darlington nuclear power plant. The province also shared its intention to add a third nuclear generating station to Bruce Power near Kincardine. 

"With this backwards approach, the Ford government is squandering a once-in-a-generation opportunity to make Ontario a global leader in attracting investment dollars and creating better jobs in the trillion-dollar clean energy sector," said Schreiner.

B.C. residents and businesses get break on electricity bills for three months

BC Hydro COVID-19 Bill Relief offers pandemic support with bill credits, rate cuts, and deferred payments for residential, small business, and industrial customers across B.C., easing utilities costs during COVID-19 economic hardship.

 

Key Points

COVID-19 bill credits, a rate cut, and deferred payments for eligible B.C. homes, small businesses, and industrial customers.

✅ Non-repayable credits equal to 3 months of average bills.

✅ Small businesses closed can skip bills for three months.

✅ Large industry may defer 50% of electricity costs.

 

B.C. residents who have lost their jobs or had their wages cut will get a three-month break on BC Hydro bills, while small businesses, amid commercial consumption plummets during COVID-19, are also eligible to apply for similar relief.

Premier John Horgan said Wednesday the credit for residential customers will be three times a household’s average monthly bill over the past year and does not have to be repaid as part of the government’s support package during the COVID-19 pandemic, as BC Hydro demand down 10% highlights the wider market pressures.

He said small businesses that are closed will not have to pay their power bills for three months, and in Ontario an Ontario COVID-19 hydro rebate complemented similar relief, and large industrial customers, including those operating mines and pulp mills, can opt to have 50 per cent of their electricity costs deferred, though a deferred costs report warned of long-term liabilities.

BC Hydro rates will be cut for all customers by one per cent as of April 1, a move similar to Ontario 2021 rate reductions that manufacturers supported lower rates at the time, after the B.C. Utilities Commission provided interim approval of an application the utility submitted last August.

Eligible residential customers can apply for bill relief starting next week and small business applications will be accepted as of April 14, while staying alert to BC Hydro scam attempts during this period, with the deadline for both categories set at June 30.

U.S. Speeds Up Permitting for Geothermal Energy

Geothermal Emergency Permitting accelerates BLM approvals on public lands via categorical exclusions for exploratory drilling and geophysical surveys, boosting domestic energy security, cutting timelines by up to a year, and streamlining low-impact reviews.

 

Key Points

A policy fast-tracking geothermal exploration on public lands, using BLM categorical exclusions to cut review delays.

✅ Categorical exclusions speed exploratory drilling approvals

✅ Cuts permitting timelines by up to one year

✅ Focused on public lands to enhance energy security

 

In a significant policy shift, the U.S. Department of the Interior has introduced emergency permitting procedures aimed at expediting the development of geothermal energy projects. This initiative, announced on May 30, 2025, is part of a broader strategy to enhance domestic energy production, seen in proposals to replace Obama's power plant overhaul and reduce reliance on foreign energy sources.

Background and Rationale

The decision to fast-track geothermal energy projects comes in the wake of President Donald Trump's declaration of a national energy emergency, which faces a legal challenge from Washington's attorney general, on January 20, 2025. This declaration cited high energy costs and an unreliable energy grid as threats to national security and economic prosperity. While the emergency order includes traditional energy resources such as oil, gas, coal, and uranium and nuclear energy resources, it notably excludes renewable sources like solar, wind, and hydrogen from its scope.

Geothermal energy, which harnesses heat from beneath the Earth's surface to generate electricity, is considered a reliable and low-emission energy source. However, its development has been hindered by lengthy permitting processes and environmental reviews, with recent NEPA rule changes influencing timelines. The new emergency permitting procedures aim to address these challenges by streamlining the approval process for geothermal projects.

Key Features of the Emergency Permitting Procedures

Under the new guidelines, the Bureau of Land Management (BLM) has adopted categorical exclusions to expedite the review and approval of geothermal energy exploration on public lands. These exclusions allow for faster permitting of low-impact activities, such as drilling exploratory wells and conducting geophysical surveys, without the need for extensive environmental assessments.

Additionally, the BLM has proposed a new categorical exclusion that would apply to operations related to the search for indirect evidence of geothermal resources. This proposal is currently open for public comment and, if finalized, would further accelerate the discovery of new geothermal resources on public lands.

Expected Impact on Geothermal Energy Development

The implementation of these emergency permitting procedures is expected to significantly reduce the time and cost associated with developing geothermal energy projects. According to the Department of the Interior, the new measures could cut permitting timelines by up to a year for certain types of geothermal exploration activities.

This acceleration in project development is particularly important given the untapped geothermal potential in regions like Nevada, which is home to some of the largest undeveloped geothermal resources in the country.

Industry and Environmental Reactions

The geothermal industry has largely welcomed the new permitting procedures, viewing them as a necessary step to unlock the full potential of geothermal energy. Industry advocates argue that reducing permitting delays will facilitate the deployment of geothermal projects, contributing to a more reliable and sustainable energy grid amid debates over electricity pricing changes that affect market signals.

However, the exclusion of solar and wind energy projects from the emergency permitting procedures has drawn criticism from some environmental groups. Critics argue that a comprehensive approach to energy development should include all renewable sources, not just geothermal, to effectively address climate change, as reflected in new EPA pollution limits for coal and gas power plants, and promote energy sustainability.

The U.S. government's move to implement emergency permitting procedures for geothermal energy development marks a significant step toward enhancing domestic energy production and reducing reliance on foreign energy sources. By streamlining the approval process for geothermal projects, the administration aims to accelerate the deployment of this reliable and low-emission energy source. While the exclusion of other renewable energy sources from the emergency procedures has sparked debate, especially after states like California halted an energy rebate program during a federal freeze, the focus on geothermal energy underscores its potential role in the nation's energy future.
