A new technology that could significantly reduce the water needed for power plant cooling is being tested, marking the beginning of research and development at the new Water Research Center WRC at Georgia Power's Plant Bowen in Cartersville, Georgia.

Cooling water is essential for most thermal, or steam-driven, electric generation, which is the primary form of producing power in the United States and globally. Although most of the water withdrawn for power generation is returned to the source, the energy industry is focused on finding more efficient ways to manage water resources.

The WRC is the first U.S. research facility of its kind, providing a venue for developing and testing technologies to reduce power plant water withdrawals and consumption and improve the quality of water related to power generation. Operated by the Southern Research Institute, the WRC is being developed by Southern Company and its subsidiary Georgia Power, Southern Research and the Electric Power Research Institute EPRI, which has assembled an R&D collaborative of 13 companies.

"This is the latest demonstration of our commitment at Georgia Power and Southern Company to develop technology solutions for providing safe, clean, reliable and affordable electricity," said Georgia Power Environmental Affairs Vice President Ron Shipman. "The WRC, a first-of-its-kind power generation water research hub at Plant Bowen, is technology leadership at its best."

Evaluation of the new technology – a thermosyphon cooler developed by Johnson Controls – is the first project to become operational at the center. According to Johnson Controls, the technology transfers heat to the environment without evaporative water loss by using an air-cooled refrigerant that pre-cools water before it enters the cooling tower. The thermosyphon cooler reduces the amount of water that must be cooled by evaporation in the cooling tower, thus reducing water consumption. The year-long testing at the WRC will document the technology's water savings potential and energy consumption characteristics.

The Water Research Center is being designed to accommodate development and evaluation of power plant water management technologies in seven areas. These include cooling tower water chemistry and advanced cooling systems process wastewater treatment zero liquid discharge options moisture recovery from power plant processes solids landfill water management carbon technology water issues and water use modeling and monitoring for best management practices.

The technologies being explored at the WRC can be implemented by power companies worldwide to address water issues and also will educate students and community leaders about the importance of water conservation and the technologies being developed to reduce water consumption.

"EPRI is pleased to be working with an industry collaborative that includes so many companies which recognize the importance of this issue of water consumption and the environmental impacts of its use," said Tom Alley, EPRI Vice President of Generation. "Current events of drought and high demands on existing water supplies emphasize the importance of water management."

Georgia Power is the largest subsidiary of Southern Company, one of the nation's largest generators of electricity. The company is an investor-owned, tax-paying utility with rates below the national average. Georgia Power serves 2.4 million customers in all but four of Georgia's 159 counties.

Southern Research is a not-for-profit scientific research organization that conducts advanced engineering research in materials, systems development, environment and energy, and preclinical drug discovery and development.

Ontario Reducing Burden on Industrial Electricity Ratepayers

Ontario Industrial Electricity Pricing Reforms aim to cut regulatory burden for industrial ratepayers through an energy concierge service, IESO billing reviews, GA estimation enhancements, clearer peak demand data, and contract cost savings.

 

Key Points

Measures to reduce industrial power costs via an energy concierge, IESO and GA reviews, and better peak demand data.

✅ Energy concierge eases pricing and connection inquiries

✅ IESO to simplify bills and refine GA estimation

✅ Real-time peak data and contract savings under review

 

Ontario's government is pursuing burden reduction measures for industrial electricity ratepayers, including legislation to lower rates to help businesses compete, and stimulate growth and investment.

Over the next year, Ontario will help industrial electricity ratepayers focus on their businesses instead of their electricity management practices by establishing an energy concierge service to provide businesses with better customer service and easier access to information about electricity pricing and changes for electricity consumers as well as connection processes.

Ontario is also tasking the Independent Electricity System Operator (IESO) to review and report back on its billing, settlement and customer service processes, building on initiatives such as electricity auctions that aim to reduce costs.

 

Improve and simplify industrial electricity bills, including clarifying the recovery rate that affects charges;

Review how the monthly Global Adjustment (GA) charge is estimated and identify potential enhancements related to cost allocation across classes; and,

Improve peak demand data publication processes and assess the feasibility of using real-time data to determine the factors that allocate GA costs to consumers.

Further, as part of the government's continued effort to finding efficiencies in the electricity system, Ontario is also directing IESO to review generation contracts to find opportunities for cost savings.

These measures are based on industry feedback received during extensive industrial electricity price consultations held between April and July 2019, which underscored how high electricity rates have impacted factories across the province.

"Our government is focused on finding workable electricity pricing solutions that will provide the greatest benefit to Ontario," said Greg Rickford, Minister of Energy, Northern Development and Mines. "Reducing regulatory burden on businesses can free up resources that can then be invested in areas such as training, new equipment and job creation."

The government is also in the process of developing further changes to industrial electricity pricing policy, amid planned rate increases announced by the OEB, informed by what was heard during the industrial electricity price consultations.

"It's important that we get this right the first time," said Minister Rickford. "That's why we're taking a thoughtful approach and listening carefully to what businesses in Ontario have to say."

Helping industrial ratepayers is part of the government's balanced and prudent plan to build Ontario together through ensuring our province is open for business and building a more transparent and accountable electricity system.

Investing in a new energy economy for Montana

Montana New Energy Economy integrates grid modernization, renewable energy, storage, and demand response to cut costs, create jobs, enable electric transportation, and reduce emissions through utility-scale efficiency, real-time markets, and distributed resources.

 

Key Points

Plan to modernize Montana's grid with renewables, storage and efficiency to lower costs, cut emissions and add jobs.

✅ Grid modernization enables real-time markets and demand response

✅ Utility-scale renewables paired with storage deliver firm power

✅ Efficiency and DERs cut peaks, costs, and pollution

 

Over the next decade, Montana ratepayers will likely invest over a billion dollars into what is now being called the new energy economy.

Not since Edison electrified a New York City neighborhood in 1882 have we had such an opportunity to rethink the way we commercially produce and consume electric energy.

Looking ahead, the modernization of Edison’s grid will lower the consumer costs, creating many thousands of permanent, well-paying jobs. It will prepare the grid for significant new loads like America going electric in transportation, and in doing so it will reduce a major source of air pollution known to directly threaten the core health of Montana and the planet.

Energy innovation makes our choices almost unrecognizable from the 1980s, when Montana last built a large, central-station power plant. Our future power plants will be smaller and more modular, efficient and less polluting — with some technologies approaching zero operating emissions.

The 21st Century grid will optimize how the supply and demand of electricity is managed across larger interconnected service areas. Utilities will interact more directly with their consumers, with utility trends guiding a new focus on providing a portfolio of energy services versus simply spinning an electric meter. Investments in utility-scale energy efficiency — LED streetlights, internet-connected thermostats, and tightening of commercial building envelopes among many — will allow consumers to directly save on their monthly bills, to improve their quality of life, and to help utilities reduce expensive and excessive peaks in demand.

The New Energy Economy will be built not of one single technology, but of many — distributed over a modernized grid across the West that approaches a real-time energy market, as provinces pursue market overhauls to adapt — connecting consumers, increasing competition, reducing cost and improving reliability.

Boldly leading the charge is a new and proven class of commercial generation powered by wind and solar energy, the latter of which employs advanced solid-state electronics, free fuel and no emissions or moving parts. Montana is blessed with wind and solar energy resources, so this is a Made-in-Montana energy choice. Note that these plants are typically paired with utility-scale energy storage investments — also an essential building block of the 21st century grid — to deliver firm, on-demand electric service.

Once considered new age and trendy, these production technologies are today competent and shovel-ready. Their adoption will build domestic energy independence. And, they are aggressively cost-competitive. For example, this year the company ISO New England — operator of a six-state grid covering all of New England — released an all-source bid for new production capacity. Unexpectedly, 100% of the winning bids were large solar electric power and storage projects, as coal and nuclear disruptions continue to shape markets. For the first time, no applications for fossil-fueled generation cleared auction.

By avoiding the burning of traditional fuels, the new energy technologies promise to offset and eventually eliminate the current 1,500 million metric tons of damaging greenhouse gases — one-quarter of the nation’s total — that are annually injected into the atmosphere by our nation’s current electric generation plants. The first step to solving the toughest and most expensive environmental issues of our day — be they costly wildfires or the regional drought that threatens Montana agriculture and outdoor recreation — is a thoughtful state energy policy, built around the new energy economy, that avoids pitfalls like the Wyoming clean energy bill now proposed.

Important potential investments not currently ready for prime time are also on the horizon, including small and highly efficient nuclear innovation in power plants — called small modular reactors (SMR) — designed to produce around-the-clock electric power with zero toxic emissions.

The nation’s first demonstration SMR plant is scheduled to be built sometime late this decade. Fingers are crossed for a good outcome. But until then, experts agree that big questions on the future commercial viability of nuclear remain unanswered: What will be SMR’s cost of electricity? Will it compete? Where will we source the refined fuel (most uranium is imported), and what will be the plan for its safe, permanent disposal?

So, what is Montana’s path forward? The short answer is: Hopefully, all of the above.

Key to Montana’s future investment success will be a respectful state planning process that learns from Texas grid improvements to bolster reliability.

Montanans deserve a smart and civil and bipartisan conversation to shape our new energy economy. There will be no need, nor place, for parties that barnstorm the state about "radical agendas" and partisan name calling – that just poisons the conversation, eliminates creative exchange and pulls us off task.

The task is to identify and vet good choices. It’s about permanently lowering energy costs to consumers. It’s about being business smart and business friendly. It’s about honoring the transition needs of our legacy energy communities. And, it’s about stewarding our world-class environment in earnest. That’s the job ahead.

New England Emergency fuel stock to cost millions

Inventoried Energy Program pays ISO-NE generators for fuel security to boost winter reliability, with FERC approval, covering fossil, nuclear, hydropower, and batteries, complementing capacity markets to enhance grid resilience during severe cold snaps.

 

Key Points

ISO-NE program paying generators to hold fuel or energy reserves for emergencies, boosting winter reliability.

✅ FERC-approved stopgap for 2023 and 2024 winter seasons

✅ Pays for on-site fuel or stored energy during cold-trigger events

✅ Open to fossil, nuclear, hydro, batteries; limited gas participation

 

Electricity ratepayers in New England will pay tens of millions of dollars to fossil fuel and nuclear power plants later this decade under a program that proponents say is needed to keep the lights on during severe winters but which critics call a subsidy with little benefit to consumers or the grid, even as Connecticut is pushing a market overhaul across the region.

Last week the Federal Energy Regulatory Commission said ISO-New England, which runs the six-state power grid, can create what it calls the Inventoried Energy Program or IEP. This basically will pay certain power plants to stockpile of fuel for use in emergencies during two upcoming winters as longer-term solutions are developed.

The federal commission called it a reasonable short-term solution to avoid brownouts which doesn’t favor any given technology.

Not all agree, however, including FERC Commissioner Richard Glick, who wrote a fiery dissent to the other three commissioners.

“The program will hand out tens of millions of dollars to nuclear, coal and hydropower generators without any indication that those payments will cause the slightest change in those generators’ behavior,” Glick wrote. “Handing out money for nothing is a windfall, not a just and reasonable rate.”

The program is the latest reaction by ISO-NE to the winter of 2013-14 when New England almost saw brownouts because of a shortage of natural gas to create electricity during a pair of week-long deep freezes.

ISO-New England says the situation is more critical now because of the possible retirement of the gas-fired Mystic Generating Station in Massachusetts. As with closed nuclear plants such as Vermont Yankee and Pilgrim in Massachusetts, power plant owners say lower electricity prices, partly due to cheap renewables and partly to stagnant demand, means they can’t be profitable just by selling power.

Programs like the IEP are meant to subsidize such plants – “incentivize” is the industry term – even though some argue there is no need to subsidize nuclear in deregulated markets so they’ll stay open if they are needed.

The IEP approved last week will be applied to the winters of 2023 and 2024, after a different subsidy program expires. It sets prices, despite warnings about rushing pricing changes from industry groups, for stocking certain amounts of fuel and payments during any “trigger” event, defined as a day when the average of high and low temperatures at Bradley International Airport in Connecticut is no more than 17 degrees Fahrenheit.

These payments will be made on top of a complex system of grid auctions used to decide how much various plants get paid for generating electricity at which times.

ISO-NE estimates the new program will cost between $102 million and $148 million each winter, depending on weather and market conditions.

It says the payments are open to plants that burn oil, coal, nuclear fuel, wood chips or trash; utility-scale battery storage facilities; and hydropower dams “that store water in a pond or reservoir.” Natural gas plants can participate if they guarantee to have fuel available, but that seems less likely because of winter heating contracts.

A major complaint and groups that filed petitions opposing the project is that ISO-NE presented little supporting evidence of how prices, amount and overall cost were determined. ISO-NE argued that there wasn’t time for such analysis before the Mystic shutdown, and FERC agreed.

“The proposal is a step in the right direction … while ISO-NE finishes developing a long-term market solution,” the commission said in its ruling.

The program is the latest example of complexities facing the nation’s electricity system evolves in the face of solar and wind power, which produce electricity so cheaply that they can render traditional power uneconomic but which can’t always produce power on demand, prompting discussions of Texas grid improvements among policymakers. Another major factor is climate change, which has increased the pressure to support renewable alternatives to plants that burn fossil fuels, as well as stagnant electricity demand caused by increased efficiency.

Opponents, including many environmental groups, say electricity utilities and regulators are too quick to prop up existing systems, as the 145-mile Maine transmission line debate shows, built when electricity was sent one way from a few big plants to many customers. They argue that to combat climate change as well as limit cost, the emphasis must be on developing “non-wire alternatives” such as smart systems for controlling demand, in order to take advantage of the current system in which electricity goes two ways, such as from rooftop solar back into the grid.

OPINION Rewiring Indian electricity

India Power Sector Crisis: a tangled market of underused plants, coal shortages, cross-subsidies, high transmission losses, and weak PPAs, requiring deregulation, power exchanges, and cost-reflective tariffs to fix insolvency and outages.

 

Key Points

India power market failure from subsidies, coal shortages, and losses, needing deregulation and reflective pricing.

✅ Deregulate to enable spot trading on power exchanges

✅ End cross-subsidies; charge cost-reflective tariffs

✅ Secure coal supply; cut T&D losses and theft

 

India's electricity industry is in a financial and political tangle.

Power producers sit on thousands of megawatts of underutilized plant, while consumers face frequent power cuts, both planned and unplanned.

Financially troubled generators struggle to escape insolvency proceedings. The state-owned banks that have mostly financed power utilities fear that debts of troubled utilities totaling 1.74 trillion rupees will soon go bad.

Aggressive bidding for supply contracts and slower-than-expected demand growth, including a recent demand slump in electricity use, is the root cause. The problems are compounded by difficulties in securing coal and other fuels, high transmission losses, electricity theft and cash-starved distribution companies.

But India's 36 state and union territory governments are contributing mightily to this financial and economic mess. They persist with populist cross-subsidies -- reducing charges for farmers and households at the cost of nonagricultural businesses, especially energy-intensive manufacturing sectors such as steel.

The states refuse to let go of their control over how electricity is produced, distributed and consumed. And they are adamant that true markets, with freedom for large industrial users to buy power at market-determined rates from whichever utility they want at power exchanges -- will not become a reality in India.

State politicians are driven mainly by the electoral need to appease farmers, India's most important vote bank, who have grown used to decades of nearly-free power.

New Delhi is therefore relying on short-term fixes instead of attempting to overhaul a defunct system. Users must pay the real cost of their electricity, as determined by a properly integrated national market free of state-level interference if India's power mess is to be really addressed.

As of Aug. 31, the country's total installed production capacity was 344,689 MW, underscoring its status as the third-largest electricity producer globally by output. Out of that, thermal power comprising coal, gas and diesel accounted for 64%, hydropower 13% and renewables accounted for 20%. Commercial and industrial users accounted for 55% of consumption followed by households on 25% and the remaining 20% by agriculture.

Coal-fired power generation, which contributes roughly 90% of thermal output and the bulk of the financially distressed generators, is the most troubled segment as it faces a secular decline in tariffs due to increasing competition from highly subsidized renewables (which also benefit from falling solar panel costs), coal shortages and weak demand.

The Central Electricity Act (CEA) 2003 opened the gates of the country's power sector for private players, who now account for 45% of generating capacity.

But easy credit, combined with an overconfident estimation of the risks involved, emboldened too many investors to pile in, without securing power purchase agreements (PPAs) with distribution companies.

As a result, power capacity grew at an annual compound rate of 11% compared to demand at 6% in the last decade leading to oversupply.

This does not mean that the electricity market is saturated. Merely that there are not enough paying customers. Distributors have plenty of consumers who will not or cannot pay, even though they have connections. There is huge unmet demand for power. There are 32 million Indian homes -- roughly 13% of the total -- mostly rural and poor with no access to electricity.

Moreover, consumption by those big commercial and industrial users which do not enjoy privileged rates is curbed by high prices, driven up by the cost of subsidizing others, extra charges on exchange-traded power and transmission and distribution losses (including theft) of 20-30%.

With renewables increasingly becoming cheaper, financially stressed distributors are avoiding long-term power purchase agreements, preferring spot markets. Meanwhile, coal shortages force generators to buy expensive imported coal supplies or cut output. The operating load for most private generators, which suffer particularly acute coal shortages in compared to state-owned utilities, has fallen from 84% in 2009-2010 to 55% now.

Smoothing coal supplies should be the top priority. Often coal is denied to power generators without long-term purchase contracts. Such discrimination in coal allocation prevails -- because the seller (state-run Coal India and its numerous subsidiaries) is an inefficient monopolist which cannot produce enough and rations coal supplies, favoring state-run generators over private.

To help power producers, New Delhi plans measures including auctioning power sales contracts with assured access to coal. However, even though coal and electricity shortages eased recently, such short-term fixes won't solve the problem. With electricity prices in secular decline, distributors are not seeking long-term supply contracts -- rather they are often looking for excuses to get out of existing agreements.

India needs a fundamental two-step reform. First, the market must be deregulated to allow most bulk suppliers and users to move to power trading exchanges, which currently account for just 10% of the market.

This would lead to genuine price discovery in a spot market and, in time, lead to the trading of electricity futures contracts. That would help in consumers and producers hedge their respective costs and revenues and safeguard their economic positions without any need for government intervention.

The second step to a healthy electricity industry is for consumers to pay the real cost of power. Cross-subsidization must end. That would promote optimal electricity use, innovation and environmental protection. Farmers enjoying nearly-free power create ecological problems by investing in water-guzzling crops such as rice and sugar cane.

Most industrial consumers, who do not have power supply privileges, have their businesses distorted and delayed by high prices. Lowering their costs would encourage power-intensive manufacturing to expand, and in the process, boost electricity demand and improve capacity utilization.

Of course, cutting theft is central to making consumers pay their way. Government officials must stop turning a blind eye to theft, especially when such transmission and distribution losses average 20%.

Politicians who want to continue subsidizing farmers or assist the poor can do so by paying cash out directly to their bank accounts, instead of wrongly relying on the power sector.

Such market-oriented reforms have long been blocked by state-level politicians, who now enjoy the influence born of operating subsidies and interfering in the sector. New Delhi must address this opposition. Narendra Modi, as a self-styled reforming prime minister, should have the courage to bite this bullet and convince state governments (starting with those ruled by his Bharatiya Janata Party) to reform. To encourage cooperation, he could offer states securing real improvements an increased share of centrally collected taxes.

Ritesh Kumar Singh is to be the chief economist of the new policy research and advocacy company Indonomics Consulting. He is former assistant director of the Finance Commission of India.

7 steps to make electricity systems more resilient to climate risks

Electricity System Climate Resilience underpins grid reliability amid heatwaves and drought, integrating solar, wind, hydropower, nuclear, storage, and demand response with efficient transmission, flexibility, and planning to secure power for homes, industry, and services.

 

Key Points

Power systems capacity to endure extreme weather and integrate clean energy, maintaining reliability and flexibility.

✅ Grid hardening, transmission upgrades, and digital forecasting.

✅ Flexible low-carbon supply: hydropower, nuclear, storage.

✅ Demand response, efficient cooling, and regional integration.

 

Summer is just half done in the northern hemisphere and yet we are already seeing electricity systems around the world struggling to cope with the severe strain of heatwaves and low rainfall.

These challenges highlight the urgent need for strong and well-planned policies and investments to improve the security of our electricity systems, which supply power to homes, offices, factories, hospitals, schools and other fundamental parts of our economies and societies. This means making our electricity systems more resilient to the effects of global warming – and more efficient and flexible as they incorporate rising levels of solar and wind power, as solar is now the cheapest electricity in history according to the IEA, which will be critical for reaching net-zero emissions in time to prevent even worse impacts from climate change.

A range of different countries, including the US, Canada and Iraq, have been hard hit by extreme weather recently in the form of unusually high temperatures. In North America, the heat soared to record levels in the Pacific Northwest. An electricity watchdog says that five US regions face elevated risks to the security of their electricity supplies this summer, underscoring US grid climate risks that could worsen, and that California’s risk level is even higher.

Heatwaves put pressure on electricity systems in multiple ways. They increase demand as people turn up air conditioning, driving higher US electricity bills for many households, and as some appliances work harder to maintain cool temperatures. At the same time, higher temperatures can also squeeze electricity supplies by reducing the efficiency and capacity of traditional thermal power plants, such as coal, natural gas and nuclear. Extreme heat can reduce the availability of water for cooling plants or transporting fuel, forcing operators to reduce their output. In some cases, it can result in power plants having to shut down, increasing the risk of outages. If the heat wave is spread over a wide geographic area, it also reduces the scope for one region to draw on spare capacity from its neighbours, since they have to devote their available resources to meeting local demand.

A recent heatwave in Texas forced the grid operator to call for customers to raise their thermostats’ temperatures to conserve energy. Power generating companies suffered outages at much higher rates than expected, providing an unwelcome reminder of February’s brutal cold snap when outages – primarily from natural gas power plants – left up to 5 million customers across the US without power over a period of four days.

At the same time, lower than average rainfall and prolonged dry weather conditions are raising concerns about hydropower’s electricity output in various parts of the world, including Brazil, China, India and North America. The risks that climate change brings in the form of droughts adds to the challenges faced by hydropower, the world’s largest source of clean electricity, highlighting the importance of developing hydropower resources sustainably and ensuring projects are climate resilient.

The recent spate of heatwaves and unusually long dry spells are fresh warnings of what lies ahead as our climate continues to heat up: an increase in the scale and frequency of extreme weather events, which will cause greater impacts and strains on our energy infrastructure.

Heatwaves will increase the challenge of meeting electricity demand while also decarbonizing the electricity supply. Today, the amount of energy used for cooling spaces – such as homes, shops, offices and factories – is responsible for around 1 billion tonnes of global CO2 emissions. In particular, energy for cooling can have a major impact on peak periods of electricity demand, intensifying the stress on the system. Since the energy demand used for air conditioners worldwide could triple by 2050, these strains are set to grow unless governments introduce stronger policy measures to improve the energy efficiency of air conditioning units.

Electricity security is crucial for smooth energy transitions
Many countries around the world have announced ambitious targets for reaching net-zero emissions by the middle of this century and are seeking to step up their clean energy transitions. The IEA’s recent Global Roadmap to Net Zero by 2050 makes it clear that achieving this formidable goal will require much more electricity, much cleaner electricity and for that electricity to be used in far more parts of our economies than it is today. This means electricity reaching much deeper into sectors such as transport (e.g. EVs), buildings (e.g. heat-pumps) and industry (e.g. electric-arc steel furnaces), and in countries like New Zealand's electrification plans it is accelerating broader efforts. As clean electricity’s role in the economy expands and that of fossil fuels declines, secure supplies of electricity become ever-more important. This is why the climate resilience of the electricity sector must be a top priority in governments’ policy agendas.

Changing climate patterns and more frequent extreme weather events can hit all types of power generation sources. Hydropower resources typically suffer in hot and dry conditions, but so do nuclear and fossil fuel power plants. These sources currently help ensure electricity systems have the flexibility and capacity to integrate rising shares of solar and wind power, whose output can vary depending on the weather and the time of day or year.

As governments and utilities pursue the decarbonization of electricity systems, mainly through growing levels of solar and wind, and carbon-free electricity options, they need to ensure they have sufficiently robust and diverse sources of flexibility to ensure secure supplies, including in the event of extreme weather events. This means that the possible decommissioning of existing power generation assets requires careful assessments that take into account the importance of climate resilience.

Ensuring electricity security requires long-term planning and stronger policy action and investment
The IEA is committed to helping governments make well-informed decisions as they seek to build a clean and secure energy future. With this in mind, here are seven areas for action for ensuring electricity systems are as resilient as possible to climate risks:

1. Invest in electricity grids to make them more resilient to extreme weather. Spending today is far below the levels needed to double the investment for cleaner, more electrified energy systems, particularly in emerging and developing economies. Economic recovery plans from the COVID-19 crisis offer clear opportunities for economies that have the resources to invest in enhancing grid infrastructure, but much greater international efforts are required to mobilize and channel the necessary spending in emerging and developing economies.

2. Improve the efficiency of cooling equipment. Cost-effective technology already exists in most markets to double or triple the efficiency of cooling equipment. Investing in higher efficiency could halve future energy demand and reduce investment and operating costs by $3 trillion between now and 2050. In advance of COP26, the Super-Efficient Equipment and Appliance Deployment (SEAD) initiative is encouraging countries to sign up to double the energy efficiency of equipment sold in their countries by 2030.

3. Enable the growth of flexible low-carbon power sources to support more solar and wind. These electricity generation sources include hydropower and nuclear, for countries who see a role for one or both of them in their energy transitions. Guaranteeing hydropower resilience in a warming climate will require sophisticated methods and tools – such as the ones implemented in Brazil – to calculate the necessary level of reserves and optimize management of reservoirs and hydropower output even in exceptional conditions. Batteries and other forms of storage, combined with solar or wind, can also provide important amounts of flexibility by storing power and releasing it when needed.

4. Increase other sources of electricity system flexibility. Demand-response and digital technologies can play an important role. The IEA estimates that only a small fraction of the huge potential for demand response in the buildings sector is actually tapped at the moment. New policies, which associate digitalization and financial behavioural incentives, could unlock more flexibility. Regional integration of electricity systems across national borders can also increase access to flexible resources.

5. Expedite the development and deployment of new technologies for managing extreme weather threats. The capabilities of electricity utilities in forecasting and situation awareness should be enhanced with the support of the latest information and communication technologies.

6. Make climate resilience a central part of policy-making and system planning. The interconnected nature of recent extreme weather events reminds us that we need to account for many contingencies when planning resilient power systems. Climate resilience should be integral to policy-making by governments and power system planning by utilities and relevant industries, and debates over Canadian climate policy underscore how grid implications must be considered. According to the recent IEA report on climate resilience, only nine out of 38 IEA member and association countries include concrete actions on climate adaptation and resilience for every segment of electricity systems.

7. Strengthen international cooperation on electricity security. Electricity underpins vital services and basic needs, such as health systems, water supplies and other energy industries. Maintaining a secure electricity supply is thus of critical importance. The costs of doing nothing in the face of growing climate threats are becoming abundantly clear. The IEA is working with all countries in the IEA family, as well as others around the world, by providing unrivalled data, analysis and policy advice on electricity security issues. It is also bringing governments together at various levels to share experiences and best practices, and identify how to hasten the shift to cleaner and more resilient energy systems.
