This one-stoplight farming hamlet had big dreams in 2005 when it was christened BioTown USA.

Its goal: to become the first U.S. community to meet all electricity and gas needs through renewable energy by using everything from farm waste to sewage.

Industry and government officials led the early charge. BP installed a gas pump offering an ethanol fuel blend, and South Dakota-based VeraSun Energy Corp. started building an ethanol production plant near town.

Former U.S. agriculture secretary Mike Johanns stopped by in support, as did the band Crosby, Stills, Nash & Young. Visitors also included a group of Chilean corn farmers who were touring the Midwest and interested in learning more about biofuels.

But the visitors are long gone, and many say the excitement is too. Money problems, leadership changes and other obstacles have sparked skepticism that Reynolds will ever succeed at moving the state, much less the nation, toward homegrown energy and away from foreign oil.

"I'm not happy about the whole situation, and a lot of people in town aren't either," said farmer Tonie Snyder. He helped provide thousands of bales of corn stover last fall that were supposed to be burned using technology that now may never be built.

From the outset, the vision for BioTown was ambitious. Indiana Gov. Mitch Daniels and the state Department of Agriculture wanted to create a model for energy self-sufficiency. No other U.S. community produces all its own energy, and a German village that runs on renewable energy took eight years to develop.

But project officials believed they could turn this community of about 550 people, surrounded by silos and stubbly corn fields, into something special.

"We are taking challenges and turning them into opportunities by developing homegrown, local energy production to become independent from foreign sources," Daniels said in announcing the project.

The timetable was aggressive. State officials hoped to break ground in November 2006 on a $10 million facility that would house the core equipment needed to turn manure and other biomass material into energy, and start generating electricity for the town by July 2007.

The groundbreaking happened, and General Motors offered deals on flex fuel vehicles to people living in the Reynolds ZIP code. But there has been little other progress, and now BioTown leaders acknowledge they have adjusted their vision. But they insist the project will happen.

"What we try to remind folks all the time is that this project, there's no manual that you pull out and say, 'How do you do a BioTown?'" Indiana Agriculture Director Andy Miller said. "We're kind of inventing it as we go."

BioTown seemed like a "shot in the arm" to Fred Buschman, a lifelong resident of this community about 80 miles northwest of downtown Indianapolis.

"It was like something you dreamed of but never really believed could happen," the 77-year-old town council member said.

A couple of restaurants, car dealerships and a gas station make up most of Reynolds proper. But steady streams of truck traffic flow through town each day on state route 43 and U.S. 24, and railroads crisscross the community. State leaders said the infrastructure and surrounding farms made Reynolds an ideal location for BioTown.

"They were going to make this a showtown for the whole world to come in and look at, and I thought it was the greatest thing that ever could happen to the town of Reynolds," Snyder said.

State officials said private funding would drive the project. The startup firm Rose Energy Discovery Inc. would install an anaerobic digester, a device that converts manure methane into electricity, and a gassifier would be built to create a gas that can be burned for heat or put in a boiler to make steam.

But Rose Energy dropped out last summer after failing to line up enough private investment. In October, VeraSun suspended construction on its ethanol plant due to a steep drop in ethanol prices, which combined with high corn prices has slowed factory construction around the country.

Work has not begun on the Reynolds digester.

Last fall, Snyder and his fellow farmers readied about 5,000 bales of mostly corn stover that was supposed to feed the gassifier. Months later, thousands of the unused bales collect snow and rain as they sit in a field just outside town.

The farmers finally received full payment for the bales earlier this month, Snyder said.

The new technology developer, Energy Systems Group, hasn't decided whether to install the gassifier, so state officials say the bales will become animal bedding.

BioTown proponents say there's still plenty going on.

Energy Systems Group, a Vectren Corp. subsidiary, will spend about $10 million on the digester and is still lining up financing for it. President Jim Adams said he hopes to start building within the next month or so and wants to produce power by the end of this year.

"The whole process has gone a little slower than we anticipated, securing the fuel and a power purchase agreement for some of the output," he said. "But that's all coming together."

Most of what they produce will likely be sold to a power company. BioTown leaders learned early that it would be nearly impossible to take Reynolds off an established electricity grid so it could supply its own power.

Miller said the cost to build a grid just for Reynolds would be prohibitive, and the community would still need backup help to prevent service interruptions.

BioTown Development Authority President John Heimlich preaches patience as the project sputters on. Last year, he and other BioTown leaders visited the German village of Juehnde, which runs on renewable energy.

"I think what we see now, maybe as our vision, is kind of an evolving project, so maybe there isn't a final look so to speak," he said.

Despite the setbacks, BioTown is attacking global energy problems with local solutions, and that's the best approach, said Brooke Coleman, director of the Boston-based New Fuels Alliance, a renewable energy advocacy group.

He said the project takes on some steep obstacles like removing a community from an established power grid. Renewable energy developers have tried to do this for years and have long met resistance from power companies.

Aside from that, the slumping economy and falling dollar make investors cautious about renewable energy technology.

"This town is tackling some of the most challenging issues facing the move toward energy independence," he said.

NDP takes aim at approval of SaskPower 8 per cent rate hike

SaskPower Rate Hike 2022-2023 signals higher electricity rates in Saskatchewan as natural gas costs surge; the Rate Review Panel approved increases, affecting residential utility bills amid affordability concerns and government energy policy shifts.

 

Key Points

An 8% SaskPower electricity rate increase split 4% in Sept 2022 and 4% in Apr 2023, driven by natural gas costs.

✅ 4% increase Sept 1, 2022; +4% on Apr 1, 2023

✅ Panel-approved amid natural gas price surge and higher fuel costs

✅ Avg residential bill up about $5 per step; affordability concerns

 

The NDP Opposition is condemning the provincial government’s decision to approve the Saskatchewan Rate Review Panel’s recommendation to increase SaskPower’s rates for the first time since 2018, despite a recent 10% rebate pledge by the Sask. Party.

The Crown electrical utility’s rates will increase four per cent this fall, and another four per cent in 2023, a trajectory comparable to BC Hydro increases over two years. According to a government news release issued Thursday, the new rates will result in an average increase of approximately $5 on residential customers’ bills starting on Sept. 1, 2022, and an additional $5 on April 1, 2023.

“The decision to increase rates is not taken lightly and came after a thorough review by the independent Saskatchewan Rate Review Panel,” Minister Responsible for SaskPower Don Morgan said in a news release, amid Nova Scotia’s 14% hike this year. “World events have caused a significant rise in the price of natural gas, and with 42 per cent of Saskatchewan’s electricity coming from natural gas-fueled facilities, SaskPower requires additional revenue to maintain reliable operations.”

But NDP SaskPower critic Aleana Young says the rate hike is coming just as businesses and industries are struggling in an “affordability crisis,” even as Manitoba Hydro scales back a planned increase next year.

She called the announcement of an eight per cent increase in power bills on a summer day before the long weekend “a cowardly move” by the premier and his cabinet, amid comparable changes such as Manitoba’s 2.5% annual hikes now proposed.

“Not to mention the Sask. Party plans to hike natural gas rates by 17% just days from now,” said Young in a news release issued Friday, as Manitoba rate hearings get underway nearby. “If Scott Moe thinks his choices — to not provide Saskatchewan families any affordability relief, to hike taxes and fees, then compound those costs with utility rate hikes — are defensible, he should have the courage to get out of his closed-door meetings and explain himself to the people of this province.”

The province noted natural gas is the largest generation source in SaskPower’s fleet. As federal regulations require the elimination of conventional coal generation in Canada by 2030, SaskPower’s reliance on natural gas generation is expected to grow, with experts in Alberta warning of soaring gas and power prices in the region. Fuel and Purchased Power expense increases are largely driven by increased natural gas prices, and SaskPower’s fuel and purchased power expense is expected to increase from $715 million in 2020-21 to $1.069 billion in 2023-24. This represents a 50 per cent increase in fuel and purchased power expense over three years.

“In the four years since our last increase SaskPower has worked to find internal efficiencies, but at this time we require additional funding to continue to provide reliable and sustainable power,” SaskPower president & CEO Rupen Pandya said in the release “We will continue to be transparent about our rate strategy and the need for regular, moderate increases.”

Top Senate Democrat calls for permanent renewable energy, storage, EV tax credits

Clean Energy Tax Incentives could expand under Democratic proposals, including ITC, PTC, and EV tax credits, boosting renewable energy, energy storage, and grid modernization within a broader infrastructure package influenced by Green New Deal goals.

 

Key Points

Federal incentives like ITC, PTC, and EV credits that cut costs and speed renewables, storage, and grid upgrades.

✅ Proposes permanence for ITC, PTC, and EV tax credits

✅ Could accelerate solar, wind, storage, and grid upgrades

✅ Passage depends on bipartisan infrastructure compromise

 

The 115th U.S. Congress has not even adjourned for the winter, and already a newly resurgent Democratic Party is making demands that reflect its majority status in the U.S. House come January.

Climate appears to be near the top of the list. Last Thursday, Senator Chuck Schumer (D-NY), the Democratic Leader in the Senate, sent a letter to President Trump demanding that any infrastructure package taken up in 2019 include “policies and funding to transition to a clean energy economy and mitigate the risks that the United States is already facing due to climate change.”

And in a list of policies that Schumer says should be included, the top item is “permanent tax incentives for domestic production of clean electricity and storage, energy efficient homes and commercial buildings, electric vehicles, and modernizing the electric grid.”

In concrete terms, this could mean an extension of the Investment Tax Credit (ITC) for solar and energy storage, the Production Tax Credit (PTC) for wind and the federal electric vehicle (EV) tax credit program as well.

 

Pressure from the Left

This strong statement on climate change, clean energy and infrastructure investment comes as at least 30 incoming members of the U.S. House of Representatives have signed onto a call for the creation of a committee to explore a “Green New Deal” and to move the nation to 100% renewable energy by 2030.*

It also comes as Schumer has come under fire by activists for rumors that he plans to replace Senator Maria Cantwell (D-Washington) with coal state Democrat Joe Manchin (D-West Virginia) as the top Democrat on the Senate Energy and Natural Resources Committee.

As such, one possible way to read these moves is that centrist leaders like Schumer are responding to pressure from an energized and newly elected Left wing of the Democratic Party. It is notable that Schumer’s program includes many of the aims of the Green New Deal, while avoiding any explicit use of that phrase.

 

Implications of a potential ITC extension

The details of levels and timelines are important here, particularly for the ITC.

The ITC was set to expire at the end of 2016, but was extended in legislative horse-trading at the end of 2015 to a schedule where it remains at 30% through the end of 2019 and then steps down for the next three years, and disappears entirely for residential projects. Since that extension the IRS has issued guidance around the use of co-located energy storage, as well as setting a standard under which PV projects can claim the ITC for the year that they begin construction.

This language around construction means that projects can start work in 2019, complete in 2023 and still claim the 30% ITC, and this may be why we at pv magazine USA are seeing an unprecedented boom in project pipelines across the United States.

Of course, if the ITC were to become permanent some of those projects would be pushed out to later years. But as we saw in 2016, despite an extension of the ITC many projects were still completed before the deadline, leading to the largest volume of PV installed in the United States in any one year to date.

This means that if the ITC were extended by the end of 2020, we could see the same thing all over again – a boom in projects created by the expected sunset, and then after a slight lull a continuation of growth.

Or it is possible that a combination of raw economics, increased investor and utility interest, and accelerating renewable energy mandates will cause solar growth rates to continue every year, and that any changes in the ITC will only be a bump against a larger trend.

While the basis for expiration of the EV tax credit is the number of vehicles sold, not any year, both the battery storage and EV industries, which many see at an inflection point, could see similar effects if the ITC and EV tax credits are made permanent.

 

Will consensus be reached?

It is also unclear that any such infrastructure package will be taken up by Republicans, or that both parties will be able to come to a compromise on this issue. While the U.S. Congress passed an infrastructure bill in 2017, given the sharp and growing differences between the two parties, and divergent trade approaches such as the 100% tariff on Chinese-made EVs, it is not clear that they will be able to come to a meaningful compromise during the next two years.

U.S. Residents Averaged Fewer Power Outages in 2022

2022 U.S. Power Outage Statistics show lower SAIDI as fewer major events hit, with SAIFI trends, electric reliability, outage duration and frequency shaped by hurricanes, winter storms, vegetation, and utility practices across states.

 

Key Points

They report SAIDI and SAIFI for 2022, showing outage duration, frequency, and impacts of major weather events.

✅ 2022 SAIDI averaged 5.6 hours; SAIFI averaged 1.4 interruptions.

✅ Fewer major events lowered outage duration versus 2021.

✅ Hurricanes and winter storms drove long outages in several states.

 

In 2022, U.S. electricity consumers on average experienced about 5.5 hours of power disruptions, a decrease from nearly two hours compared to 2021. This information comes from the latest Annual Electric Power Industry Report. The reduction in yearly power interruptions primarily resulted from fewer significant events in 2022 compared to the previous year, and utility disaster planning continues to support grid resilience as severe weather persists.

Since 2013, excluding major events, the annual average duration of power interruptions has consistently hovered around two hours. Factors contributing to major power disruptions include weather-related incidents, vegetation interference near power lines, and specific utility practices, while pandemic-related grid operations influenced workforce planning more than outage frequency. To assess the reliability of U.S. electric utilities, two key indexes are utilized:

  • The System Average Interruption Duration Index (SAIDI) calculates the total length (in hours) an average customer endures non-brief power interruptions over a year.
  • The System Average Interruption Frequency Index (SAIFI) tracks the number of times interruptions occur.

The influence of major events on electrical reliability is gauged by comparing affected states' SAIDI and SAIFI values against the U.S. average, which was 5.6 hours of outages and 1.4 outages per customer in 2022. The year witnessed 18 weather-related disasters in the U.S., each resulting in over $1 billion in damages, and COVID-19 grid assessments indicated the electricity system was largely safe from pandemic impacts. Noteworthy major events include:

  • Hurricane Ian in September 2022, leaving over 2.6 million Floridian customers without electricity, with restoration in some areas taking weeks rather than days.
  • Hurricane Nicole in November 2022, causing over 300,000 Florida customers to lose power.
  • Winter Storm Elliott in December 2022, affecting over 1.5 million customers in multiple states including Texas where utilities struggled after Hurricane Harvey to restore service, and Florida, and bringing up to four feet of snow in parts of New York.

In 2022, states like Florida, West Virginia, Maine, Vermont, and New Hampshire experienced the most prolonged power interruptions, with New Hampshire averaging 10.3 hours and Florida 19.1 hours, and FPL's Irma storm response illustrates how restoration can take days or weeks in severe cases. Conversely, the District of Columbia, Delaware, Rhode Island, Nebraska, and Iowa had the shortest total interruptions, with the District of Columbia averaging just 34 minutes and Iowa 85 minutes.

The frequency of outages, unlike their duration, is more often linked to non-major events. Across the nation, Alaska recorded the highest number of power disruptions per customer (averaging 3.5), followed by several heavily forested states like Tennessee and Maine. Power outages due to falling tree branches are common, particularly during winter storms that burden tree limbs and power lines, as seen in a North Seattle outage affecting 13,000 customers. The District of Columbia stood out with the shortest and fewest outages per customer.

From smart meters to big batteries, co-ops emerge as clean grid laboratories

Minnesota Electric Cooperatives are driving grid innovation with smart meters, time-of-use pricing, demand response, and energy storage, including iron-air batteries, to manage peak loads, integrate wind and solar, and cut costs for rural members.

 

Key Points

Member-owned utilities piloting load management, meters, and storage to integrate wind and solar, cutting peak demand.

✅ Time-of-use pricing pilots lower bills and shift peak load.

✅ Iron-air battery tests add multi-day, low-cost energy storage.

✅ Smart meters enable demand response across rural co-ops.

 

Minnesota electric cooperatives have quietly emerged as laboratories for clean grid innovation, outpacing investor-owned utilities on smart meter installations, time-based pricing pilots, and experimental battery storage solutions.

“Co-ops have innovation in their DNA,” said David Ranallo, a spokesperson for Great River Energy, a generation and distribution cooperative that supplies power to 28 member utilities — making it one of the state’s largest co-op players.

Minnesota farmers helped pioneer the electric co-op model more than a century ago, similar to modern community-generated green electricity initiatives, pooling resources to build power lines, transformers and other equipment to deliver power to rural parts of the state. Today, 44 member-owned electric co-ops serve about 1.7 million rural and suburban customers and supply almost a quarter of the state’s electricity.

Co-op utilities have by many measures lagged on clean energy. Many still rely on electricity from coal-fired power plants. They’ve used political clout with rural lawmakers to oppose new pollution regulations and climate legislation, and some have tried to levy steep fees on customers who install solar panels.

Where they are emerging as innovators is with new models and technology for managing electric grid loads — from load-shifting water heaters to a giant experimental battery made of iron. The programs are saving customers money by delaying the need for expensive new infrastructure, and also showing ways to unlock more value from cheap but variable wind and solar power.

Unlike investor-owned utilities, “we have no incentive to invest in new generation,” said Darrick Moe, executive director of the Minnesota Rural Electric Association. Curbing peak energy demand has a direct financial benefit for members.

Minnesota electric cooperatives have launched dozens of programs, such as the South Metro solar project, in recent years aimed at reducing energy use and peak loads, in particular. They include:

Cost calculations are the primary driver for electric cooperatives’ recent experimentation, and a lighter regulatory structure and evolving electricity market reforms have allowed them to act more quickly than for-profit utilities.

“Co-ops and [municipal utilities] can act a lot more nimbly compared to investor-owned utilities … which have to go through years of proceedings and discussions about cost-recovery,” said Gabe Chan, a University of Minnesota associate professor who has researched electric co-ops extensively. Often, approval from a local board is all that’s required to launch a venture.

Great River Energy’s programs, which are rebranded and sold through member co-ops, yielded more than 101 million kilowatt-hours of savings last year — enough to power 9,500 homes for a year.

Beyond lowering costs for participants and customers at large, the energy-saving and behavior-changing programs sometimes end up being cited as case studies by larger utilities considering similar offerings. Advocates supporting a proposal by the city of Minneapolis and CenterPoint Energy to allow residents to pay for energy efficiency improvements on their utility bills through distributed energy rebates used several examples from cooperatives.

Despite the pace of innovation on load management, electric cooperatives have been relatively slow to transition from coal-fired power. More than half of Great River Energy’s electricity came from coal last year, and Dairyland Power, another major power wholesaler for Minnesota co-ops, generated 70% of its energy from coal. Meanwhile, Xcel Energy, the state’s largest investor-owned utility, has already reduced coal to about 20% of its energy mix.

The transition to cleaner power for some co-ops has been slowed by long-term contracts with power suppliers that have locked them into dirty power. Others have also been stalled by management or boards that have been resistant to change. John Farrell, director of the Institute for Local Self-Reliance’s Energy Democracy program, said generalizing co-ops is difficult. 

“We’ve seen some co-ops that have got 75-year contracts for coal, that are invested in coal mines and using their newsletter to deny climate change,” he said. “Then you see a lot of them doing really amazing things like creating energy storage systems … and load balancing [programs], because they are unique and locally managed and can have that freedom to experiment without having to go through a regulatory process.”

Great River Energy, for its part, says it intends to reach 54% renewable generation by 2025, while some communities, like Frisco, Colorado, are targeting 100% clean electricity by specific dates. Its members recently voted to sell North Dakota’s largest coal plant, but the arrangement involves members continuing to buy power from the new owners for another decade.

The cooperative’s path to clean power could become clearer if its experimental iron-air battery project is successful. The project, the first of its kind in the country, is expected to be completed by 2023.

National Grid to lose Great Britain electricity role to independent operator

UK Future System Operator to replace National Grid as ESO, enabling smart grid reform, impartial system planning, vehicle-to-grid, long duration storage, and data-driven oversight to meet net zero and cut consumer energy costs.

 

Key Points

The UK Future System Operator is an independent ESO and planner, steering net zero with impartial data and smart grid coordination.

✅ Replaces National Grid ESO with independent system operator

✅ Enables smart grid, vehicle-to-grid, and long-duration storage

✅ Supports net zero, lower bills, and impartial system planning

 

The government plans to strip National Grid of its role keeping Great Britain’s lights on as part of a proposed “revolution’” in the electricity network driven by smart digital grid technologies.

The FTSE 100 company has played a role in managing the energy system of England, Scotland and Wales, including efforts such as a subsea power link that brings renewable power from Scotland to England (Northern Ireland has its own network). It is the electricity system operator, balancing supply and demand to ensure the electricity supply. But it will lose its place at the heart of the industry after government officials put forward plans to replace it with an independent “future system operator”.

The new system controller would help steer the country towards its climate targets, at the lowest cost to energy bill payers, by providing impartial data and advice after an overhaul of the rules governing the energy system to make it “fit for the future”.

The plans are part of a string of new proposals to help connect millions of electric cars, smart appliances and other green technologies to the energy system, and to fast-track grid connections nationwide, which government officials believe could help to save £10bn a year by 2050, and create up to 10,000 jobs for electricians, data scientists and engineers.

The new regulations aim to make it easier for electric cars to export electricity from their batteries back on to the power grid or to homes when needed. They could also help large-scale and long-duration batteries play a role in storing renewable energy, supported by infrastructure such as a 2GW substation helping integrate supply, so that it is available when solar and wind power generation levels are low.

Anne-Marie Trevelyan, the energy and climate change minister, said the rules would allow households to “take control of their energy use and save money” while helping to make sure there is clean electricity available “when and where it’s needed”.

She added: “We need to ensure our energy system can cope with the demands of the future. Smart technologies will help us to tackle climate change while making sure that the lights stay on and bills stay low.”

The energy regulator, Ofgem, raised concerns earlier this year that National Grid would face a “conflict of interest” in providing advice on the future electricity system because it also owns energy networks that stand to benefit financially from future investment plans. It called for a new independent operator to take its place.

Jonathan Brearley, Ofgem’s chief executive, said the UK requires a “revolution” in how and when it uses electricity, including demand shifts during self-isolation to help meet its climate targets and added that the government’s plans for a new digital energy system were “essential” to meeting this goal “while keeping energy bills affordable for everyone”.

A National Grid spokesperson said the company would “work closely” with the government and Ofgem on the role of a future system operator, as well as “the most appropriate ownership model and any future related sale”.

The division has earned National Grid, which has addressed cybersecurity fears in supplier choices, an average of £199m a year over the last five years, or 1.3% of the group’s total revenues, which are split between the UK – where it operates high-voltage transmission lines in England and Wales, and the country’s gas system – and its growing energy supply business in the US, aligned with investment in a smarter electricity infrastructure in the US to modernize grids.

IEA warns fall in global energy investment may lead to shortages

Global Energy Investment Decline risks future oil and electricity supply, says the IEA, as spending on upstream, coal plants, and grids falls while renewables, storage, and flexible generation lag in the energy transition.

 

Key Points

Multi-year cuts to oil, power, and grid spending that increase risks of future supply shortages and market tightness.

✅ IEA warns underinvestment risks oil supply squeeze

✅ China and India slow coal plant additions; renewables rise

✅ Batteries aid flexibility but cannot replace seasonal storage

 

An almost 20 per cent fall in global energy investment over the past three years could lead to oil and electricity shortages, as surging electricity demand persists, and there are concerns about whether current business models will encourage sufficient levels of spending in the future, according a new report.

The International Energy Agency’s second annual IEA benchmark analysis of energy investment found that while the world spent $US1.7 trillion ($2.2 trillion) on fossil-fuel exploration, new power plants and upgrades to electricity grids last year, with electricity investment surpassing oil and gas even as global energy investment was down 12 per cent from a year earlier and 17 per cent lower than 2014.

While the IEA said continued oversupply of oil and electricity globally would prevent any imminent shock, falling investment “points to a risk of market tightness and undercapacity at some point down the line’’.

The low crude oil price drove a 44 per cent drop in oil and gas investment between 2014 and 2016. It fell 26 per cent last year. It was due to falls in upstream activity and a slowdown in the sanctioning of conventional oilfields to the lowest level in more than 70 years.

“Given the depletion of existing fields, the pace of investment in conventional fields will need to rise to avoid a supply squeeze, even on optimistic assumptions about technology and the impact of climate policies on oil demand,’’ the IEA warned in its report released yesterday evening. “The energy transition has barely begun in several key sectors, such as transport and industry, which will continue to rely heavily on oil, gas and coal for the foreseeable future.’’

The fall in global energy spending also reflected declining investment in power generation, particularly from coal plants.

While 21 per cent of global ­energy investment was made by China in 2016, the world’s fastest growing economy had a 25 per cent decline in the commissioning of new coal-fired power plants, due largely to air pollution issues and investment in renewables.

Investment in new coal-fired plants also fell in India.

“India and China have slammed the brakes on coal-fired generation. That is the big change we have seen globally,’’ said ­Bruce Mountain a director at CME Australia.

“What it confirms is the ­pressures and the changes we are seeing in Australia, the restructuring of our energy supply, is just part of a global trend. We are facing the pressures more sharply in Australia because our power prices are very high. But that same shift in energy source in Australia are being mirrored internationally.’’ The IEA — a Paris-based adviser to the OECD on energy policy — also highlighted Australia’s reduced power reserves in its report and called for regulatory change to encourage greater use of renewables.

“Australia has one of the highest proportions of households with PV systems on their roof of any country in the world, and its ­electricity use in its National ­Electricity Market is spread out over a huge and weakly connected network,’’ the report said.

“It appears that a series of accompanying investments and regulatory changes are needed, including a plan to avoid supply threats, to use Australia’s abundant wind and solar potential: changing system operation methods and reliability procedures as well as investment into network capacity, flexible generation and storage.’’ The report found that in Australia there had been an increase in grid-scale installations mostly associated with large-scale solar PV plants.

Last month the Turnbull ­government revealed it was prepared to back the construction of new coal-fired power stations to prevent further shortfalls in electricity supplies, while the PM ruled out taxpayer-funded plants and declared it was open to using “clean coal” technology to replace existing generators.

He also pledged “immediate” ­action to boost the supply of gas by forcing exporters to divert ­production into the domestic ­market.

Since then technology billionaire Elon Musk has promised to solve South Australia’s energy ­issues by building the world’s largest lithium-ion battery in the state.

But the IEA report said batteries were unlikely to become a “one size fits all” single solution to ­electricity security and flexibility provision.

“While batteries are well-suited to frequency control and shifting hourly load, they cannot provide seasonal storage or substitute the full range of technical services that conventional plants provide to stabilise the system,’’ the report said.

“In the absence of a major technological breakthrough, it is most likely that batteries will complement rather than substitute ­conventional means of providing system flexibility. While conventional plants continue to provide essential system services, their business model is increasingly being called into question in ­unbundled systems.’’
