Fourteen months after expanding an incentive program for customers who generate their own power from renewable sources such as solar and wind, TVA has temporarily stopped accepting new customers to the Generation Partners program.

The news, which emerged from a TVA meeting with distributors in Nashville, came as a jolt to the state's solar industry, which has been flourishing under the program that, coupled with state and federal grants, has helped turn the otherwise cost-prohibitive technology into a reasonable investment. TVA said it is halting the program because of excessive demand.

Part of TVA's Green Power Switch program, Generation Partners pays a 12-cent-per-kilowatt-hour premium above the retail rate for solar power and a 3-cent-per-kilowatt-hour premium for other renewable energy, including wind and biomass. Through the incentive program, a customer with solar panels, for example, generates power that flows onto TVA's electric grid. The customer then receives credit for that power on each month's electric bill.

Last year, TVA expanded the incentives to include larger solar installations as well as biomass generation projects. The freeze does not impact current Generation Partners customers.

Ken Elder, owner of solar startup Soltility in Friendsville, said he learned of the freeze through an e-mail from another solar firm late June 16 and received an e-mail notification the following day from Nashville Electric Service. TVA did not issue formal information regarding the program until June 18.

"The folks that are working with me are just devastated because we are just really gearing up with potential customers," said Elder, who has been working as a consultant in the industry and is beginning to develop small commercial and residential projects on his own.

"TVA could do a lot of damage just studying this for six or eight weeks. Almost as bad as that, they could come back and say, 'We're going to re-implement the program, but it's not going to be at 12 cents per kilowatt hour, it's going to be 4 cents,' " Elder added.

Considered a pilot program by the federal power provider, Generation Partners is limited to a total of 200 megawatts of power generation and $50 million in total power purchased through the program.

An influx of applications following a recent change to the application procedure for the program resulted in the moratorium on new projects, said Susan Curtis, senior manager of TVA's Generation Partners program, via e-mail. The change allows projects to be approved prior to purchase and installation, "which allows financing for more customers," Curtis said.

"We received many more applications than anticipated in a short period of time. We did communicate with distributors as soon as we realized there was an issue and that it was escalating," she added. "We've always had open communications with distributors offering the program."

Locally, there are about a "half-dozen" solar projects in various stages of planning and construction, said Steve Noe, key account manager for KUB. Utility officials learned about TVA's decision at the Nashville meeting and had no prior indication there might not be room for all customers under the program's current structure.

"We didn't really know what was going on on TVA's side of that," Noe said. "I guess that's why it sort of came as a surprise to everybody."

Among those local projects are commercial and residential solar installations as well as government projects including a system for Knoxville's new transit center, a 500-solar panel project for the Knoxville Convention Center and a project pairing the city of Knoxville's Solar America Cities program with Knox Heritage to install solar as part of a local Victorian home rehab project.

"Our projects are kind of up in the air in that respect," said Susanna Bass, sustainability program manager for the city of Knoxville. "I'm not sitting on the panic button right now. Obviously, the sooner we know something the easier we breathe."

Also at stake is an expected bonanza of solar projects to be funded by the Tennessee Solar Institute at the University of Tennessee and funded with federal stimulus dollars. The institute is taking over a state-run grant program for solar and related clean energy projects, which recently received a tranche of federal stimulus money and will begin accepting grant applications.

"The danger is that the Department of Energy, which is funding the local programs is going to say, 'You're going to have to re-appropriate the money," said Gil Milear-Hough, Tennessee director of renewable programs for the Southern Alliance for Clean Energy who also works on contract as part of Knoxville's Solar Cities program. "When you say bad timing, DOE is saying we wanted this money spent yesterday."

For example, Bass said, while the deadline to spend all of the city's stimulus dollars is August 2011, she must spend 20 percent by Sept. 30 and 50 percent by June 30, 2011. So Bass is on the lookout for non-Generation Partners projects to help fulfill the earlier deadlines if needed.

"It's just too early to determine whether it's really going to affect our program," said Kimberly Holbrook, spokeswoman for the Solar Institute. "I think right now it's a developing story. Our goal is to facilitate the grant application process. That's going to be our immediate focus, and we're moving ahead with that."

Tennessee Solar Institute officials were not available for more detailed comment and officials with the Tennessee Department of Economic and Community Development did not return a call for comment.

Knoxville solar installation firm Efficient Energy of Tennessee already has broken ground on the state's first megawatt-sized solar installation and is preparing to hire 10 people to complete the project.

What was supposed to be a "good news" story for the company has become more of a nail-biter, said Harvey Abouelata, Efficient Energy's vice president of sales and marketing.

"It's already going, the train has left the station," Abouelata said of the project located on Andrew Johnson Highway. "This month was supposed to be whooping and hollering and celebrating.... I hope this is a blip on the radar."

The problem is not that TVA can't afford the initiative but simply that, as a pilot program, Generation Partners must operate within certain parameters, Milear-Hough said.

"It's largely an accounting problem," he said. "Every pilot has a $50 million cap. To go beyond that requires creating a program, and that does require a board action. But the board doesn't meet until August."

TVA is working to come up with both short-term and long-term solutions, according to the federal utility's statement. TVA's energy services committee will meet to discuss options, Noe said, and KUB has indicated it wants to be part of the process.

"The short-term changes will be announced this summer," Curtis said. "We do not know the time frame for the long-term changes and don't know what they will require."

Solar companies say they can't handle more than a few weeks of uncertainty.

"Nobody's going to be able to get financing or anything without the Generation Partners program," Abouelata said. "Small companies like ours, we can't survive six months of no business."

TCA Electric Leads Hydrogen Crane Project at Vancouver Port

Hydrogen Fuel Cell Crane Port of Vancouver showcases zero-emission RTG technology by DP World, TCA Electric, and partners, using hydrogen-electric fuel cells, battery energy storage, and regenerative capture to decarbonize container handling operations.

 

Key Points

A retrofitted RTG crane powered by hydrogen fuel cells, batteries, and regeneration to cut diesel use and CO2 emissions.

✅ Dual fuel cell system charges high-voltage battery

✅ Regenerative capture reduces energy demand and cost

✅ Pilot targets zero-emission RTG fleets by 2040

 

In a groundbreaking move toward sustainable logistics, TCA Electric, a Chilliwack-based industrial electrical contractor, is at the forefront of a pioneering hydrogen fuel cell crane project at the Port of Vancouver. This initiative, led by DP World in collaboration with TCA Electric and other partners, marks a significant step in decarbonizing port operations and showcases the potential of hydrogen technology in heavy-duty industrial applications.

A Vision for Zero-Emission Ports

The Port of Vancouver, Canada's largest port, has long been a hub for international trade. However, its operations have also contributed to substantial greenhouse gas emissions, even as DP World advances an all-electric berth in the U.K., primarily from diesel-powered Rubber-Tired Gantry (RTG) cranes. These cranes are essential for container handling but are significant sources of CO₂ emissions. At DP World’s Vancouver terminal, 19 RTG cranes account for 50% of diesel consumption and generate over 4,200 tonnes of CO₂ annually. 

To address this, the Vancouver Fraser Port Authority and the Province of British Columbia have committed to transforming the port into a zero-emission facility by 2050, supported by provincial hydrogen investments that accelerate clean energy infrastructure across B.C. This ambitious goal has spurred several innovative projects, including the hydrogen fuel cell crane pilot. 

TCA Electric’s Role in the Hydrogen Revolution

TCA Electric's involvement in this project underscores its expertise in industrial electrification and commitment to sustainable energy solutions. The company has been instrumental in designing and implementing the electrical systems that power the hydrogen fuel cell crane. This includes integrating the Hydrogen-Electric Generator (HEG), battery energy storage system, and regenerative energy capture technologies. The crane operates using compressed gaseous hydrogen stored in 15 pressurized tanks, which feed a dual fuel cell system developed by TYCROP Manufacturing and H2 Portable. This system charges a high-voltage battery that powers the crane's electric drive, significantly reducing its carbon footprint. 

The collaboration between TCA Electric, TYCROP, H2 Portable, and HTEC represents a convergence of local expertise and innovation. These companies, all based in British Columbia, have leveraged their collective knowledge to develop a world-first solution in the industrial sector, while regional pioneers like Harbour Air's electric aircraft illustrate parallel progress in aviation. TCA Electric's leadership in this project highlights its role as a key enabler of the province's clean energy transition. 

Demonstrating Real-World Impact

The pilot project began in October 2023 with the retrofitting of a diesel-powered RTG crane. The first phase included integrating the hydrogen-electric system, followed by a one-year field trial to assess performance metrics such as hydrogen consumption, energy generation, and regenerative energy capture rates. Early results have been promising, with the crane operating efficiently and emitting only steam, compared to the 400 kilograms of CO₂ produced by a comparable diesel unit. 

If successful, this project could serve as a model for decarbonizing port operations worldwide, mirroring investments in electric trucks at California ports that target landside emissions. DP World plans to consider converting its fleet of RTG cranes in Vancouver and Prince Rupert to hydrogen power, aligning with its global commitment to achieve carbon neutrality by 2040.

Broader Implications for the Industry

The success of the hydrogen fuel cell crane pilot at the Port of Vancouver has broader implications for the shipping and logistics industry. It demonstrates the feasibility of transitioning from diesel to hydrogen-powered equipment in challenging environments, and aligns with advances in electric ships on the B.C. coast. The project's success could accelerate the adoption of hydrogen technology in other ports and industries, contributing to global efforts to reduce carbon emissions and combat climate change.

Moreover, the collaboration between public and private sectors in this initiative sets a precedent for future partnerships aimed at advancing clean energy solutions. The support from the Province of British Columbia, coupled with the expertise of companies like TCA Electric and utility initiatives such as BC Hydro's vehicle-to-grid pilot underscore the importance of coordinated efforts in achieving sustainability goals.

Looking Ahead

As the field trial progresses, stakeholders are closely monitoring the performance of the hydrogen fuel cell crane. The data collected will inform decisions on scaling the technology and integrating it into broader port operations. The success of this project could pave the way for similar initiatives in other regions, complementing the province's move to electric ferries with CIB support, promoting the widespread adoption of hydrogen as a clean energy source in industrial applications.

TCA Electric's leadership in this project exemplifies the critical role of skilled industrial electricians in driving the transition to sustainable energy solutions. Their expertise ensures the safe and efficient implementation of complex systems, making them indispensable partners in the journey toward a zero-emission future.

The hydrogen fuel cell crane pilot at the Port of Vancouver represents a significant milestone in the decarbonization of port operations. Through innovative partnerships and local expertise, this project is setting the stage for a cleaner, more sustainable future in global trade and logistics.

New clean energy investment in developing nations slipped sharply last year: report

Developing Countries Clean Energy investment fell as renewable energy financing slowed in China; solar and wind growth lagged while coal power hit new highs, raising emissions risks for emerging markets and complicating climate change goals.

 

Key Points

Renewables investment and power trends in emerging nations: solar, wind, coal shifts, and steps toward decarbonization.

✅ Investment fell to $133b; China dropped to $86b

✅ Coal power rose to 6,900 TWh; 47% generation share

✅ New coal builds declined to 39 GW, decade low

 

New clean energy investment slid by more than a fifth in developing countries last year due to a slowdown in China, while the amount of coal-fired power generation jumped to a new high, reflecting global power demand trends, a recent annual survey showed.

Bloomberg New Energy Finance (BNEF) surveyed 104 emerging markets and found that developing nations were moving towards cleaner, low-emissions sources in many regions, but not fast enough to limit carbon dioxide emissions or the effects of climate change.

New investment in wind, solar and other clean energy projects dropped to $133 billion last year from $169 billion a year earlier, mainly due to a slump in Chinese investment, even as electricity investment globally surpasses oil and gas for the first time, the research showed.

China’s clean energy investment fell to $86 billion from $122 billion a year earlier, with dynamics in China's electricity sector also in focus. Investment by India and Brazil also declined, mainly due to lower costs for solar and wind.

However, the volume of coal-fired power generation produced and consumed in developing countries increased to a new high of 6,900 terrawatt hours (TWh) last year, even as renewables are poised to eclipse coal globally, from 6,400 TWh in 2017.

The increase of 500 TWh is equivalent to the power consumed in the U.S. state of Texas in one year, underscoring how surging electricity demand is putting power systems under strain. Coal accounted for 47% of all power generation across the 104 countries.

“The transition from coal toward cleaner sources in developing nations is underway,” said Ethan Zindler, head of Americas at BNEF. “But like trying to turn a massive oil tanker, it takes time.”

Despite the spike in coal-fired generation, the amount of new coal capacity which was added to the grid in developing countries declined, with Europe's renewables crowding out gas offering a contrasting pathway. New construction of coal plants fell to its lowest level in a decade last year of 39 gigawatts (GW).

The report comes a week ahead of United Nations climate talks in Madrid, Spain, where more than 190 countries will flesh out the details of an accord to limit global warming.

India to Ration Coal Supplies as Electricity Demand Surges

India Coal Supply Rationing redirects shipments from high-inventory power plants to stations facing shortages as electricity demand surges, inventories fall, and outages persist; Coal India, NTPC imports, and smaller mines bolster domestic supply.

 

Key Points

A temporary policy redirecting coal from high-stock plants to shortage-hit plants amid rising demand

✅ Shipments halted 1 week to plants with >14 days coal stock

✅ Smaller mines asked to raise output; NTPC to import 270,000 tons

✅ Outages at Adani and Tata Mundra units pressure domestic supply

 

India will ration coal supplies to power plants with high inventories to direct more shipments to stations battling shortages, even as shortages ease in some regions, as surging demand outstrips production.

Supplies to plants with more than two weeks’ coal inventory will be halted for a week, a team headed by federal Coal Secretary Alok Kumar decided on Saturday, the Power Ministry said in a statement. The government has also requested smaller mines to raise output to supplement shipments from state miner Coal India Ltd., and is taking steps to get nuclear back on track to diversify the energy mix.

A jump in electricity consumption spurred by a reviving economy and an extended summer, after an earlier steep demand decline in India, is driving demand for coal, which helps produce about 70% of the nation’s electricity. The surge in demand complicates India’s clean-energy transition efforts amid solar supply headwinds that cloud near-term alternatives, and may bolster arguments favoring the country’s dependence on coal to fuel economic growth.

“There’s no doubt India will continue to need coal for stable power for years,” said Rupesh Sankhe, vice president at Elara Capital India Pvt. in Mumbai. “Plants that meet environmental standards and are able to produce power efficiently will see utilization rising, but I doubt we’re going to have many new coal plants.”  

Coal stockpiles at the country’s power plants had fallen to 14.7 million tons as of Aug. 24, tumbling 62% from a year earlier, according to the latest data from the Central Electricity Authority. More than 88 gigawatts of generation plants, about half the capacity monitored by the power ministry, had inventories of six days or less as of that date, the data show. Power demand jumped 10.5% in July from a year earlier, even as global electricity use dipped 15% during the pandemic, according to the government.
Outages at some large plants that run on imported coal have increased the burden on those that burn domestic supplies, aiding shortfalls.

Adani Power Ltd. had almost 2 gigawatts of capacity in outage at its Mundra plant in Gujarat at the start of the week, while Tata Power Co. Ltd. had shut 80% of its 4-gigawatt plant in the same town for maintenance, power ministry data show.

NTPC Ltd., the largest power generator, will import the 270,000 tons of coal it left out from contracts placed earlier to mitigate the fuel shortage, reflecting higher imported coal volumes this fiscal, the power ministry said in a separate statement.

A tidal project in Scottish waters just generated enough electricity to power nearly 4,000 homes

MeyGen Tidal Stream Project delivers record 13.8 GWh to Scotland's grid, showcasing renewable ocean energy. Simec Atlantis Energy's 6 MW array of tidal turbines advances EU power goals and plans an ocean-powered data center.

 

Key Points

A Scottish tidal energy array exporting record power, using four 1.5 MW turbines and driving renewable innovation.

✅ Delivered 13.8 GWh to the grid in 2019, a project record.

✅ Four 1.5 MW turbines in Phase 1A, 6 MW installed.

✅ Plans include an ocean-powered data center near site.

 

A tidal power project in waters off the north coast of Scotland, where Scotland’s wind farms also deliver significant output, sent more than 13.8 gigawatt hours (GWh) of electricity to the grid last year, according to an operational update issued Monday. This figure – a record – almost doubled the previous high of 7.4 GWh in 2018.

In total, the MeyGen tidal stream array has now exported more than 25.5 GWh of electricity to the grid since the start of 2017, according to owners Simec Atlantis Energy. Phase 1A of the project is made up of four 1.5 megawatt (MW) turbines.

The 13.8 GWh of electricity exported in 2019 equates to the average yearly electricity consumption of roughly 3,800 “typical” homes in the U.K., where wind power records have been set recently, according to the company, with revenue generation amounting to £3.9 million ($5.09 million).

Onshore maintenance is now set to be carried out on the AR1500 turbine used by the scheme, with Atlantis aiming to redeploy the technology in spring.

In addition to the production of electricity, Atlantis is also planning to develop an “ocean-powered data centre” near the MeyGen project.

The European Commission has described “ocean energy” as being both abundant and renewable, and milestones like the biggest offshore windfarm starting U.K. supply underscore wider momentum, too. It’s estimated that ocean energy could potentially contribute roughly 10% of the European Union’s power demand by the year 2050, according to the Commission.

While tidal power has been around for decades — EDF’s 240 MW La Rance Tidal Power Plant in France was built as far back as 1966, and the country’s first offshore wind turbine has begun producing electricity — recent years have seen a number of new projects take shape.

In December last year, Scottish tidal energy business Nova Innovation was issued with a permit to develop a project in Nova Scotia, Canada, aiming to harness the Bay of Fundy tides in the region further.

In an announcement at the time, the firm said a total of 15 tidal stream turbines would be installed by the year 2023. The project, according to the firm, will produce enough electricity to power 600 homes, as companies like Sustainable Marine begin delivering tidal energy to the Nova Scotia grid.

Elsewhere, a business called Orbital Marine Power is developing what it describes as the world’s most powerful tidal turbine, with grid-supplied output already demonstrated.

The company says the turbine will have a swept area of more than 600 square meters and be able to generate “over 2 MW from tidal stream resources.” It will use a 72-meter-long “floating superstructure” to support two 1 MW turbines.

Calgary electricity retailer urges government to scrap overhaul of power market

Alberta Capacity Market Overhaul faces scrutiny over electricity costs, reliability targets, investor certainty, and AESO design, as UCP reviews NDP reforms, renewables integration, and deregulated energy-only alternatives impacting generators, ratepayers, and future power price volatility.

 

Key Points

A shift paying generators for capacity and energy to improve reliability; critics warn of higher electricity costs.

✅ UCP reviewing NDP plan and subsidies amid market uncertainty

✅ AESO cites reliability needs as coal retires, renewables grow

✅ Critics predict overprocurement and premature launch cost spikes

 

Jason Kenney's government is facing renewed pressure to cancel a massive overhaul of Alberta's power market that one player says will needlessly spike costs by hundreds of millions of dollars, amid an electricity sector in profound change today.

Nick Clark, who owns the Calgary-based electricity retailer Spot Power, has sent the Alberta government an open letter urging it to walk away from the electricity market changes proposed by the former NDP government.

"How can you encourage new industry to open up when one of their raw material costs will increase so dramatically?" Clark said. "The capacity market will add more costs to the consumer and it will be a spiral downwards."

But NDP Leader Rachel Notley, whose government ushered in the changes, said fears over dramatic cost increases are unfounded.

"There are some players within the current electricity regime who have a vested interest in maintaining the current situation," Notley said

Kenney's UCP vowed during the recent election to review the current and proposed electricity market options, as the electricity market heads for a reshuffle, with plans to report on its findings within 90 days.

The party also promised to scrap subsidies for renewable power, while ensuring "a market-based electricity system" that emphasizes competition in Alberta's electricity market for consumers.

The New Democrats had opted to scrap the current deregulated power market — in place since the Klein era — after phasing out coal-fired generation and ushering in new renewable power as part of changes in how Alberta produces and pays for electricity under their climate change strategy.

The Alberta Electric System Operator, which oversees the grid, says the province will need new sources of electricity to replace shuttered coal plants and backstop wind and solar generators, while meeting new consumer demand.

After consulting with power companies and investors, the AESO concluded in late 2016 the electricity market couldn't attract enough investment to build the needed power generation under the current model.

The AESO said at the time investors were concerned their revenues would be uncertain once new plants are running. It recommended what's known as a capacity market, which compensates power generators for having the ability to produce electricity, even when they're not producing it.

In other words, producers would collect revenue for selling electricity into the grid and, separately, for having the capacity to produce power as a backstop, ensuring the lights stay on. Power generators would use this second source of income to help cover plant construction costs.

Clark said the complex system introduces unnecessary costs, which he believes would hurt consumers in the end. He said what's preventing investment in the power market is uncertainty over how the market will be structured in the future.

"What investors need to see in this market is price certainty, regulatory ease, and where the money they're putting into the marketplace is not at risk," he said.

"They can risk their own money, but if in fact the government comes in and changes the policy as it was doing, then money stayed away from the province."

Notley said a capacity market would not increase power bills but would avoid big price swings, with protections like a consumer price cap on power bills also debated, while bringing greener sources of energy into Alberta's grid.

"Moving back to the [deregulated] energy-only market would make a lot of money for a few people, and put consumers, both industrial and residential, at great risk."

Clark disagrees, citing Enmax's recent submissions to the Alberta Utilities Commission, in which the utility argues the proposed design of the capacity market is flawed.

In its submissions to the commission, which is considering the future of Alberta's power market, Enmax says the proposed system would overestimate the amount of generation capacity the province will need in the future. It says the calculation could result in Alberta procuring too much capacity.

The City of Calgary-owned utility says this could drive up costs by anywhere from $147 million to $849 million a year. It says a more conservative calculation of future electricity demand could avoid the extra expense.

An analysis by a Calgary energy consulting firm suggests a different feature of the proposed power market overhaul could also lead to a massive spike in costs.

EDC Associates, hired by the Consumers' Coalition of Alberta, argues the proposal to launch the new system in November 2021 may be premature, because it could bring in additional supplies of electricity before they're needed.

The consultant's report, also filed with the Alberta Utilities Commission, estimates the early launch date could require customers to pay 40 per cent more for electricity amid rising electricity prices in the province — potentially an extra $1.4 billion — in 2021/22.

"The target implementation date is politically driven by the previous government," said Duane Reid-Carlson, president of EDC Associates.

Reid-Carlson recommends delaying the launch date by several years and making another tweak: reducing the proposed target for system reliability, which would scale back the amount of power generation needed to backstop renewable sources.

"You could get a result in the capacity market that would give a similar cost to consumers that the [deregulated] energy-only market design would have done otherwise," he said.

"You could have a better risk profile associated with the capacity market that would serve consumers better through lower cost, lower price volatility, and it would serve generators better by giving them better access to capital at lower costs."

The UCP government did not respond to a request for comment.

"Kill the viability": big batteries to lose out from electricity grid rule change

AEMC Storage Charging Rules spark industry backlash as Tesla, Snowy Hydro, and investors warn transmission charges on batteries and pumped hydro could deter grid-scale storage, distort the National Electricity Market, and slow decarbonisation.

 

Key Points

AEMC Storage Charging Rules are proposals to bill grid storage for network use, shaping costs and investment.

✅ Charges apply when batteries draw power; double-charging concerns.

✅ Tesla and Snowy Hydro warn of reduced viability and delays.

✅ AEMO recommends exemptions; investors seek certainty.

 

Tesla, Snowy Hydro and other big suppliers of storage capacity on Australia’s main electricity grid warn proposed rule changes amount to a tax on their operations that will deter investors and slow the decarbonisation of the industry.

The Australian Energy Market Commission (AEMC) will release its final decision this Thursday on new rules for integrating batteries, pumped hydro and other forms of storage.

The AEMC’s draft decision, released in July, angered many firms because it proposed charging storage providers for drawing power, ignoring a recommendation by the Australian Electricity Market Operator (AEMO) that they be exempt.

Battery maker Tesla, which has supplied some of the largest storage to the National Electricity Market, said in a submission that the charges would “kill the commercial viability of all grid storage projects, causing inefficient investment in alternative network”, with consumers paying higher costs.

Snowy Hydro, which is building the giant Snowy 2 pumped storage project and already operates a smaller one, said in its submission the proposed changes if implemented would jeopardise investment.

“This is a major policy change, amounting to a tax on infrastructure critical to achieving a renewable future,” Snowy Hydro said.

AEMO itself argued it was important storage providers were not “disincentivised from connecting to the transmission network, as they generally provide a net benefit to the power system by charging at periods of low demand”.

Australia’s electricity grid faces economic and engineering challenges, similar to Ontario's storage push as it adjusts to the arrival of lower cost and also lower carbon alternatives to fossil fuels.

While rule changes are necessary to account for operators that can both draw from and supply power, how they are implemented can have long-lasting effects on the technologies that get encouraged or repelled, including control of EV charging issues, independent experts say.

“It doesn’t have to be this way,” said Bruce Mountain, director of the Victoria Energy Policy Centre. “In Britain, where the UK grid transformation is underway, the regulator dealing with the same issues has said that storage devices don’t pay the system charges when they withdraw electricity from the grid,” he said.

The prospect that storage operators will have to pay transmission charges could “drastically” affect their profitability since their business models rely on the difference between the price their pay for power and how much they can sell it for. Gas generators and network monopolies would benefit from the change, Mountain said.

An AEMC spokesperson said the commission had consulted widely, including from those who objected to the payment for transmission access.

“The market is moving towards a future that will be increasingly reliant on energy storage to firm up the growing volume of renewable energy and deliver on the increasing need for critical system security services, with examples such as EVs supporting grid stability in California as the ageing fleet of thermal generators retire,” the spokesperson said, declining to elaborate on the final ruling before it is published.

“The regulatory framework needs to facilitate this transition as the energy sector continues to decarbonise,” the official said.

AusNet, which operates the Victorian energy transmission grid, said that while “technological neutrality is paramount for battery and hybrid unit connections to both the distribution and transmission networks,” it did not back charging storage access to networks in all cases.

“[Ausnet] supports a clear exemptions framework for energy storage providers,” a spokesperson said. “We recommend that batteries and other hybrid facilities should have transmission use of system charges waived if they provide a net benefit to network customers.”

We are not aware of anyone that supports the charging storage access to networks in all circumstances.

“Batteries and hybrid facilities that consume energy from the network should be provided no preferential treatment relative to other customers and generators.”

Jonathan Upson, a principal at Strategic Renewable Consulting, though, said the AEMC wants electricity flowing through batteries to be taxed twice to pay network charges – once when the electricity charges the battery and then again when the same electricity is sent out by the battery an hour or two later but this time with customers paying.

“The AEMC’s draft decision has the identical rationale for eliminating franking credits on all dividends, resulting in double taxing of company profits,” he said.

Christiaan Zuur, director of energy transformation at the Clean Energy Council, said that while much of AEMC’s draft proposal was constructive, “those benefits are either nullified or maybe even outweighed” by uncertainty over charges.

“Risk perception” will be important since potential newcomers won’t be sure of what charges they will pay to connect to the grid and existing operators could have their connection agreements reopened, Zuur said.

“Investors focus on the potential risk. It does factor through to the integral costs for projects,” he said.

The outcome of new charges may prompt more people to put batteries on their premises and draw power from their own solar panels, Mountain said, with rising EV adoption introducing new grid challenges, cutting their reliance on a centralised network.

“Ironically, it encourages customers to depend less and less on the grid,” he said. “It’s almost like the capture of the dominant interests playing out over time at their own expense.”

Separately, the latest edition of the Clean Energy Council Confidence Index shows leadership by state governments is helping to shore up investor appetite for investing in renewable energy amid 2021 electricity lessons even with higher 2030 emissions reduction goals from the federal government.

Overall, investor confidence increased by a point in the last six months – from 6.3 to 7.3 out of 10 – following strong commitments and policy development from state governments, particularly on the east coast, the council said.

“The results of this latest survey illustrate the economic value in policy that lowers the emissions footprint of our electricity generation, supporting regional centres and creating jobs. Investors recognise the opportunities created by limiting global temperature rise to 1.5 degrees,” said council chief executive Kane Thornton.

Among the states, NSW, Victoria and Queensland led in terms of positive investor sentiment.

Correction: this article was amended on 30 November. An earlier version stated Ausnet supported charging storage for network access. A spokesperson said it backed a waiver on charges if certain conditions are met.
