Energy Efficiency Standards face congressional scrutiny as bipartisan rules meet regulatory reform proposals like the REINS Act, risking appliance standards, consumer savings, grid reliability, and pollution cuts secured through transparent review and stakeholder consensus.

 

Key Points

Federal rules set minimum performance for appliances to cut costs, reduce pollution, and ease grid demand.

✅ Backed by 30 years of bipartisan support and stakeholder input

✅ Proposed REINS Act could delay or block new efficiency rules

✅ Typical households save about $500 annually under current standards

 

A coalition of energy efficiency groups, trade associations, energy efficiency organizations, environmental organizations, and consumer groups sent a letter to congressional leaders Friday voicing concern about legislative efforts that threaten years of bipartisan, cost-saving rules and standards on energy efficiency.

Bills being considered in the House and Senate would eliminate longstanding checks and balances that ensure thorough review and debate before Congress can eliminate federal regulation implemented appropriately under the law, including bipartisan efficiency standards. Lawmakers are also considering proposals such as the “REINS Act” that could effectively block new standards by adding lengthy, burdensome new steps to the regulatory process, even as energy groups warn of rushed electricity pricing changes, based on arbitrary cost limits that ignore the tremendous net financial gains to consumers from energy efficiency standards.

“We urge you to proceed with caution as Congress considers how best to accomplish broad regulatory reform and debates energy-related tax incentives to ensure that cost-saving energy efficiency standards, which have enjoyed 30 years of bipartisan support, are not put at risk,” the groups wrote in the letter.

The groups signing the letter were the Alliance to Save Energy, American Council for an Energy-Efficient Economy, Appliance Standards Awareness Project, ASHRAE, California Energy Commission, Consumer Federation of America, Copper Development Association, Cree, Environmental and Energy Study Institute, Hannon Armstrong, Midwest Energy Efficiency Alliance, National Consumer Law Center on Behalf of its Low Income Clients, Natural Resources Defense Council, Northeast Energy Efficiency Partnerships, Polyisocyanurate Insulation Manufacturers Association, Southeast Energy Efficiency Alliance, Southwest Energy Efficiency Project, Urban Green Council, and Vermont Energy Investment Corporation.

“Efficiency standards that take years to review, analyze and develop – with extensive involvement and most often the support from the industries and other stakeholders affected – are threatened by these sweeping bills,” Alliance to Save Energy President Kateri Callahan said. “Congress absolutely should review and update regulations where necessary, but it can and should do so under the current rules that already provide meaningful checks and balances. Businesses and consumers need a predictable playing field in which utility rate designs can evolve without being upended every time we have a power shift in Washington.”

The groups said some of these legislative proposals would make it far too easy for Congress to eliminate in one reckless and fell swoop dozens of regulations that have been years in the making.

They cited the “Midnight Rules Relief Act” that recently passed the House and has been introduced in the Senate. It would allow Congress to quickly rescind all regulations finalized since June 13. Among regulations finalized since then are several significant appliance standards, including, dehumidifiers, battery chargers and compressors. Several more standards have been issued but await final administrative approval under the Trump administration as a potential Clean Power Plan replacement is weighed by officials.

“These are not last-minute standards rushed in under the cover of darkness,” said ASAP Executive Director Andrew deLaski. “They were developed over years of transparent public review and stakeholder negotiation. Many of them have broad consensus support from affected industries that have long since adapted to the new rules and don’t want to see them changed.”

“There should be no question about the benefits of efficiency standards. A typical household with products meeting the latest standards is saving about $500 a year,” said ACEEE Executive Director Steven Nadel. “Appliance prices have dropped as the standards have been enacted and consumers have more product choices than ever before. And at the same time, we’ve reduced stress on the grid, significantly cut pollution, and, alongside a clean electricity standard, eliminated the need for expensive new power plants that drive up utility rates.”

Dewa in China to woo renewable energy firms

Dewa-China Renewable Energy Partnership advances solar, clean energy, smart grid, 5G, cloud, and Big Data, linking Dewa with Hanergy and Huawei for R&D, smart meters, demand management, and resilient network infrastructure.

 

Key Points

A Dewa collaboration with Hanergy and Huawei to co-develop solar, smart grid, 5G, cloud, and resilient utility networks.

✅ MoU expands solar PV and distributed generation in Dubai and China

✅ Smart grid R&D: smart meters, demand response, self-healing networks

✅ 5G, cloud, and Big Data enable secure, scalable smart city services

 

A high-level delegation from Dubai Electricity and Water Authority (Dewa) recently visited China in bid to build closer ties with Chinese renewable and clean energy and smart services and smart grid companies, amid broader power grid modernization in Asia trends.

The team led by the managing director and CEO Saeed Mohammed Al Tayer visited the headquarters of Hanergy Holding Group, one of the largest international companies in alternative and renewable energy, in Beijing.

The visit complements the co-operation between Dewa and Hanergy after the signing MoU between the two sides last May, said a statement from Dewa.

The two parties focused on renewable and clean energy and its development, including efforts to integrate solar into the grid through advanced programs, and enhancing opportunities for joint investment.

Al Tayer also visited the Exhibition Hall and Exhibition Centre of the Hanergy Clean Energy Exhibition spread over a 7,000-sq-m area at the Beijing Olympic Park.

He discussed solar power technologies and applications, which included integrated photovoltaic panels and their distribution on the roofs of industrial and residential buildings, residential and mobile power systems, micro-grid installations in remote regions, solar-powered vehicles, and various elements of the exhibition.

Al Tayer and the accompanying delegation later visited the Beijing R&D Centre, which is one of Huaweis largest research institutes, known for Huawei smart grid initiatives across global markets, that employs over 12,000 people. The centre covers the latest pre-5G solutions, Cloud, Big Data, as well as vertical solutions for a smart and safe city.

"The visit is part of a joint venture with Huawei, which includes R&D projects to develop smart network infrastructures and various mechanisms and technologies, aligned with recent U.S. grid improvement funding initiatives, such as smart meters for electricity and water services, energy demand management, and self-recovery mechanisms from errors and disasters," he added.

US Government Condemns Russia for Power Grid Hacking

Russian Cyberattacks on U.S. Critical Infrastructure target energy grids, nuclear plants, water systems, and aviation, DHS and FBI warn, using spear phishing, malware, and ICS/SCADA intrusion to gain footholds for potential sabotage and disruption.

 

Key Points

State-backed hacks targeting U.S. energy, nuclear, water and aviation via phishing and ICS access for sabotage.

✅ DHS and FBI detail multi-stage intrusion since 2016

✅ Targets include energy, nuclear, water, aviation, manufacturing

✅ TTPs: spear phishing, lateral movement, ICS reconnaissance

 

Russia is attacking the U.S. energy grid, with reported power plant breaches unfolding alongside attacks on nuclear facilities, water processing plants, aviation systems, and other critical infrastructure that millions of Americans rely on, according to a new joint analysis by the FBI and the Department of Homeland Security.

In an unprecedented alert, the US Department of Homeland Security (DHS) and FBI have warned of persistent attacks by Russian government hackers on critical US government sectors, including energy, nuclear, commercial facilities, water, aviation and manufacturing.

The alert details numerous attempts extending back to March 2016 when Russian cyber operatives targeted US government and infrastructure.

The DHS and FBI said: “DHS and FBI characterise this activity as a multi-stage intrusion campaign by Russian government cyber-actors who targeted small commercial facilities’ networks, where they staged malware, conducted spear phishing and gained remote access into energy sector networks.

“After obtaining access, the Russian government cyber-actors conducted network reconnaissance, moved laterally and collected information pertaining to industrial control systems.”

The Trump administration has accused Russia of engineering a series of cyberattacks that targeted American and European nuclear power plants and water and electric systems, and could have sabotaged or shut power plants off at will.

United States officials and private security firms saw the attacks as a signal by Moscow that it could disrupt the West’s critical facilities in the event of a conflict.

They said the strikes accelerated in late 2015, at the same time the Russian interference in the American election was underway. The attackers had compromised some operators in North America and Europe by spring 2017, after President Trump was inaugurated.

In the following months, according to the DHS/FBI report, Russian hackers made their way to machines with access to utility control rooms and critical control systems at power plants that were not identified. The hackers never went so far as to sabotage or shut down the computer systems that guide the operations of the plants.

Still, new computer screenshots released by the Department of Homeland Security have made clear that Russian state hackers had the foothold they would have needed to manipulate or shut down power plants.

“We now have evidence they’re sitting on the machines, connected to industrial control infrastructure, that allow them to effectively turn the power off or effect sabotage,” said Eric Chien, a security technology director at Symantec, a digital security firm.

“From what we can see, they were there. They have the ability to shut the power off. All that’s missing is some political motivation,” Mr. Chien said.

American intelligence agencies were aware of the attacks for the past year and a half, and the Department of Homeland Security and the F.B.I. first issued urgent warnings to utility companies in June, 2017. Both DHS/FBI have now offered new details as the Trump administration imposed sanctions against Russian individuals and organizations it accused of election meddling and “malicious cyberattacks.”

It was the first time the administration officially named Russia as the perpetrator of the assaults. And it marked the third time in recent months that the White House, departing from its usual reluctance to publicly reveal intelligence, blamed foreign government forces for attacks on infrastructure in the United States.

In December, the White House said North Korea had carried out the so-called WannaCry attack that in May paralyzed the British health system and placed ransomware in computers in schools, businesses and homes across the world. Last month, it accused Russia of being behind the NotPetya attack against Ukraine last June, the largest in a series of cyberattacks on Ukraine to date, paralyzing the country’s government agencies and financial systems.

But the penalties have been light. So far, President Trump has said little to nothing about the Russian role in those attacks.

The groups that conducted the energy attacks, which are linked to Russian intelligence agencies, appear to be different from the two hacking groups that were involved in the election interference.

That would suggest that at least three separate Russian cyberoperations were underway simultaneously. One focused on stealing documents from the Democratic National Committee and other political groups. Another, by a St. Petersburg “troll farm” known as the Internet Research Agency, used social media to sow discord and division. A third effort sought to burrow into the infrastructure of American and European nations.

For years, American intelligence officials tracked a number of Russian state-sponsored hacking units as they successfully penetrated the computer networks of critical infrastructure operators across North America and Europe, including in Ukraine.

Some of the units worked inside Russia’s Federal Security Service, the K.G.B. successor known by its Russian acronym, F.S.B.; others were embedded in the Russian military intelligence agency, known as the G.R.U. Still others were made up of Russian contractors working at the behest of Moscow.

Russian cyberattacks surged last year, starting three months after Mr. Trump took office.

American officials and private cybersecurity experts uncovered a series of Russian attacks aimed at the energy, water and aviation sectors and critical manufacturing, including nuclear plants, in the United States and Europe. In its urgent report in June, the Department of Homeland Security and the F.B.I. notified operators about the attacks but stopped short of identifying Russia as the culprit.

By then, Russian spies had compromised the business networks of several American energy, water and nuclear plants, mapping out their corporate structures and computer networks.

They included that of the Wolf Creek Nuclear Operating Corporation, which runs a nuclear plant near Burlington, Kan. But in that case, and those of other nuclear operators, Russian hackers had not leapt from the company’s business networks into the nuclear plant controls.

Forensic analysis suggested that Russian spies were looking for inroads — although it was not clear whether the goal was to conduct espionage or sabotage, or to trigger an explosion of some kind.

In a report made public in October, Symantec noted that a Russian hacking unit “appears to be interested in both learning how energy facilities operate and also gaining access to operational systems themselves, to the extent that the group now potentially has the ability to sabotage or gain control of these systems should it decide to do so.”

The United States sometimes does the same thing. It bored deeply into Iran’s infrastructure before the 2015 nuclear accord, placing digital “implants” in systems that would enable it to bring down power grids, command-and-control systems and other infrastructure in case a conflict broke out. The operation was code-named “Nitro Zeus,” and its revelation made clear that getting into the critical infrastructure of adversaries is now a standard element of preparing for possible conflict.

Sanctions Announced

The US treasury department has imposed sanctions on 19 Russian people and five groups, including Moscow’s intelligence services, for meddling in the US 2016 presidential election and other malicious cyberattacks.

Russia, for its part, has vowed to retaliate against the new sanctions.

The new sanctions focus on five Russian groups, including the Russian Federal Security Service, the country’s military intelligence apparatus, and the digital propaganda outfit called the Internet Research Agency, as well as 19 people, some of them named in the indictment related to election meddling released by special counsel Robert Mueller last month.

In announcing the sanctions, which will generally ban U.S. people and financial institutions from doing business with those people and groups, the Treasury Department pointed to alleged Russian election meddling, involvement in the infrastructure hacks, and the NotPetya malware, which the Treasury Department called “the most destructive and costly cyberattack in history.”

The new sanctions come amid ongoing criticism of the Trump administration’s reluctance to punish Russia for cyber and election meddling. Sen. Mark Warner (D-Va.) said that, ahead of the 2018 mid-term elections, the administration’s decision was long overdue but not enough. “Nearly all of the entities and individuals who were sanctioned today were either previously under sanction during the Obama Administration, or had already been charged with federal crimes by the Special Counsel,” Warner said.

 

Warning: The Russians Are Coming

In an updated warning to utility companies, DHS/FBI officials included a screenshot taken by Russian operatives that proved they could now gain access to their victims’ critical controls, prompting a renewed focus on protecting the U.S. power grid among operators.

American officials and security firms, including Symantec and CrowdStrike, believe that Russian attacks on the Ukrainian power grid in 2015 and 2016 that left more than 200,000 citizens there in the dark are an ominous sign of what the Russian cyberstrikes may portend in the United States and Europe in the event of escalating hostilities.

Private security firms have tracked the Russian government assaults on Western power and energy operators — conducted alternately by groups under the names Dragonfly campaigns alongside Energetic Bear and Berserk Bear — since 2011, when they first started targeting defense and aviation companies in the United States and Canada.

By 2013, researchers had tied the Russian hackers to hundreds of attacks on the U.S. power grid and oil and gas pipeline operators in the United States and Europe. Initially, the strikes appeared to be motivated by industrial espionage — a natural conclusion at the time, researchers said, given the importance of Russia’s oil and gas industry.

But by December 2015, the Russian hacks had taken an aggressive turn. The attacks were no longer aimed at intelligence gathering, but at potentially sabotaging or shutting down plant operations.

At Symantec, researchers discovered that Russian hackers had begun taking screenshots of the machinery used in energy and nuclear plants, and stealing detailed descriptions of how they operated — suggesting they were conducting reconnaissance for a future attack.

Eventhough the US government enacted sanctions, cybersecurity experts are still questioning where the Russian attacks could lead, given that the United States was sure to respond in kind.

“Russia certainly has the technical capability to do damage, as it demonstrated in the Ukraine,” said Eric Cornelius, a cybersecurity expert at Cylance, a private security firm, who previously assessed critical infrastructure threats for the Department of Homeland Security during the Obama administration.

“It is unclear what their perceived benefit would be from causing damage on U.S. soil, especially given the retaliation it would provoke,” Mr. Cornelius said.

Though a major step toward deterrence, publicly naming countries accused of cyberattacks still is unlikely to shame them into stopping. The United States is struggling to come up with proportionate responses to the wide variety of cyberespionage, vandalism and outright attacks.

Lt. Gen. Paul Nakasone, who has been nominated as director of the National Security Agency and commander of United States Cyber Command, the military’s cyberunit, said during his recent Senate confirmation hearing, that countries attacking the United States so far have little to worry about.

“I would say right now they do not think much will happen to them,” General Nakasone said. He later added, “They don’t fear us.”

Why Is Georgia Importing So Much Electricity?

Georgia Electricity Imports October 2017 surged as hydropower output fell and thermal power plants underperformed; ESCO balanced demand via low-cost imports, mainly from Azerbaijan, amid rising tariffs, kWh consumption growth, and a widening generation-consumption gap.

 

Key Points

They mark a record import surge due to costly local generation, lower hydropower, ESCO balancing costs, and rising demand.

✅ Imports rose 832% YoY to 157 mln kWh, mainly from Azerbaijan

✅ TPP output fell despite capacity; only low-tariff plants ran

✅ Balancing price 13.8 tetri/kWh signaled costly domestic PPAs

 

In October 2017, Georgian power plants generated 828 mln. KWh of electricity, marginally up (+0.79%) compared to September. Following the traditional seasonal pattern and amid European concerns over dispatchable power shortages affecting markets, the share of electricity produced by renewable sources declined to 71% of total generation (87% in September), while thermal power generation’s share increased, accounting for 29% of total generation (compared to 13% in September). When we compare last October’s total generation with the total generation of October 2016, however, we observe an 8.7% decrease in total generation (in October 2016, total generation was 907 mln. kWh). The overall decline in generation with respect to the previous year is due to a simultaneous decline in both thermal power and hydro power generation. 

Consumption of electricity on the local market in the same period was 949 mln. kWh (+7% compared to October 2016, and +3% with respect to September 2017), and reflected global trends such as India's electricity growth in recent years. The gap between consumption and generation increased to 121 mln. kWh (15% of the amount generated in October), up from 100 mln. kWh in September. Even more importantly, the situation was radically different with respect to the prior year, when generation exceeded consumption.

The import figure for October was by far the highest from the last 12 years (since ESCO was established), occurring as Ukraine electricity exports resumed regionally, highlighting wider cross-border dynamics. In October 2017, Georgia imported 157 mln. kWh of electricity (for 5.2 ¢/kWh – 13 tetri/kWh). This constituted an 832% increase compared to October 2016, and is about 50% larger than the second largest import figure (104.2 mln. kWh in October 2014). Most of the October 2017 imports (99.6%) came from Azerbaijan, with the remaining 0.04% coming from Russia.

The main question that comes to mind when observing these statistics is: why did Georgia import so much? One might argue that this is just the result of a bad year for hydropower generation and increased demand. This argument, however, is not fully convincing. While it is true that hydropower generation declined and demand increased, the country’s excess demand could have been easily satisfied by its existing thermal power plants, even as imported coal volumes rose in regional markets. Instead of increasing, however, the electricity coming from thermal power plants declined as well. Therefore, that cannot be the reason, and another must be found. The first that comes to mind is that importing electricity may have been cheaper than buying it from local TPPs, or from other generators selling electricity to ESCO under power purchase agreements (PPAs). We can test the first part of this hypothesis by comparing the average price of imported electricity to the price ceiling on the tariff that TPPs can charge for the electricity they sell. Looking at the trade statistics from Geostat, the average price for imported electricity in October 2017 remained stable with respect to the same month of the previous year, at 5.2 ¢ (13 tetri) per kWh. Only two thermal power plants (Gardabani and Mtkvari) had a price ceiling below 13 tetri per kWh. Observing the electricity balance of Georgia, we see that indeed more than 98% of the electricity generated by TPPs in October 2017 was generated by those two power plants.

What about other potential sources of electricity amid Central Asia's power shortages at the time? To answer this question, we can use the information derived from the weighted average price of balancing electricity. Why balancing electricity? Because it allows us to reconstruct the costs the market operator (ESCO) faced during the month of October to make sure demand and supply were balanced, and it allows us to gain an insight about the price of electricity sold through PPAs.

ESCO reports that the weighted average price of balancing electricity in October 2017 was 13.8 tetri/kWh, (25% higher than in October 2016, when it was below the average weighted cost of imports – 11 vs. 13 – and when the quantity of imported electricity was substantially smaller). Knowing that in October 2017, 61% of balancing electricity came from imports, while 39% came from hydropower and wind power plants selling electricity to ESCO under their PPAs, we can deduce that in this case, internal generation was (on average) also substantially more expensive than imports. Therefore, the high cost of internally generated electricity, rather than the technical impossibility of generating enough electricity to satisfy electricity demand, indeed appears to be one the main reasons why electricity imports spiked in October 2017.

Energy Efficiency and Demand Response Can Nearly Level Southeast Electricity Demand for More than a Decade

Southeast Electricity Demand Forecast examines how energy efficiency, photovoltaics, electric vehicles, heat pumps, and demand response shape grid needs, stabilize load through 2030, shift peaks, and inform utility planning across the region.

 

Key Points

An outlook of load shaped by efficiency, solar, EVs, with demand response keeping usage steady through 2030.

✅ Stabilizes regional demand through 2030 under accelerated adoption

✅ Energy efficiency and demand response are primary levers

✅ EVs and heat pumps drive growth post 2030; shift winter peaks

 

Electricity markets in the Southeast are facing many changes on the customer side of the meter. In a new report released today, we look at how energy efficiency, photovoltaics (solar electricity), electric vehicles, heat pumps, and demand response (shifting loads from periods of high demand) might affect electricity needs in the Southeast.

We find that if all of these resources are pursued on an accelerated basis, electricity demand in the region can be stabilized until about 2030.

After that, demand will likely grow in the following decade because of increased market penetration of electric vehicles and heat pumps, but energy planners will have time to deal with this growth if these projections are borne out. We also find that energy efficiency and demand response can be vital for managing electricity supply and demand in the region and that these resources can help contain energy demand growth, reducing the impact of expensive new generation on consumer wallets.

 

National trends

This is the second ACEEE report looking at regional electricity demand. In 2016, we published a study on electricity consumption in New England, finding an even more pronounced effect. For New England, with even more aggressive pursuit of energy efficiency and these other resources, consumption was projected to decline through about 2030, before rebounding in the following decade.

These regional trends fit into a broader national pattern. In the United States, electricity consumption has been characterized by flat electricity demand for the past decade. Increased energy efficiency efforts have contributed to this lack of consumption growth, even as the US economy has grown since the Great Recession. Recently, the US Energy Information Administration (EIA – a branch of the US Department of Energy) released data on US electricity consumption in 2016, finding that 2016 consumption was 0.3% below 2015 consumption, and other analysts reported a 1% slide in 2023 on milder weather.

 

Five scenarios for the Southeast

ACEEE’s new study focuses on the Southeast because it is very different from New England, with warmer weather, more economic growth, and less-aggressive energy efficiency and distributed energy policies than the Northeast. For the Southeast, we examined five scenarios: a business-as-usual scenario; two alternative scenarios with progressively higher levels of energy efficiency, photovoltaics informed by a solar strategy for the South that is emerging regionally, electric vehicles, heat pumps, and demand response; and two scenarios combining high numbers of electric vehicles and heat pumps with more modest levels of the other resources. This figure presents electricity demand for each of these scenarios:

Over the 2016-2040 period, we project that average annual growth will range from 0.1% to 1.0%, depending on the scenario, much slower than historic growth in the region. Energy efficiency is generally the biggest contributor to changes in projected 2040 electricity consumption relative to the business-as-usual scenario, as shown in the figure below, which presents our accelerated scenario that is based on levels of energy efficiency and other resources now targeted by leading states and utilities in the Southeast.

To date, Entergy Arkansas has achieved the annual efficiency savings as a percent of sales shown in the accelerated scenario and Progress Energy (a division of Duke Energy) has nearly achieved those savings in both North and South Carolina. Sixteen states outside the Southeast have also achieved these savings statewide.

The efficiency savings shown in the aggressive scenario have been proposed by the Arkansas PSC. This level of savings has already been achieved by Arizona as well as six other states. Likewise, the demand response savings we model have been achieved by more than 10 utilities, including four in the Southeast. The levels of photovoltaic, electric vehicle, and heat pump penetration are more speculative and are subject to significant uncertainty.

We also examined trends in summer and winter peak demand. Most utilities in the Southeast have historically had peak demand in the summer, often seeing heatwave-driven surges that stress operations across the Eastern U.S., but our analysis shows that winter peaks will be more likely in the region as photovoltaics and demand response reduce summer peaks and heat pumps increase winter peaks.

 

Why it’s vital to plan broadly

Our analysis illustrates the importance of incorporating energy efficiency, demand response, and photovoltaics into utility planning forecasts as utility trends to watch continue to evolve. Failing to include these resources leads to much higher forecasts, resulting in excess utility system investments, unnecessarily increasing customer electricity rates. Our analysis also illustrates the importance of including electric vehicles and heat pumps in long-term forecasts. While these technologies will have moderate impacts over the next 10 years, they could become increasingly important in the long run.

We are entering a dynamic period of substantial uncertainty for long-term electricity sales and system peaks, highlighted by COVID-19 demand shifts that upended typical patterns. We need to carefully observe and analyze developments in energy efficiency, photovoltaics, electric vehicles, heat pumps, and demand response over the next few years. As these technologies advance, we can create policies to reduce energy bills, system costs, and harmful emissions, drawing on grid reliability strategies tested in Texas, while growing the Southeast’s economy. Resource planners should be sure to incorporate these emerging trends and policies into their long-term forecasts and planning.

Electricity distributors warn excess solar power in network could cause blackouts, damage infrastructure

Australian Rooftop Solar Grid Constraints are driving debates over voltage rise, export limits, inverter curtailment, DER integration, and network reliability, amid concerns about localized blackouts, infrastructure protection, tariff reform, and battery storage adoption.

 

Key Points

Limits on solar exports to curb voltage rise, protect equipment, and keep the distribution grid reliable.

✅ Voltage rise triggers transformer protection and local outages.

✅ Export limits and smart inverter curtailment manage midday backfeed.

✅ Tariff reform and DER orchestration defer costly network upgrades.

 

With almost 1.8 million Australian homes and businesses relying on power from rooftop solar panels, there is a fight brewing over the impact of solar energy on the national electricity grid.

Electricity distributors are warning that as solar uptake continues to increase, there is a risk excess solar power could flow into the network, elevating power outage risks, causing blackouts and damaging infrastructure.

But is it the network businesses that are actually at risk, as customers turn away from centrally produced electricity?

This is what three different parties have to say:

Andrew Dillon of the network industry peak body, Energy Networks Australia (ENA), told 7.30 the way customers are charged for electricity has to change, or expensive grid upgrades to poles and wires will be needed to keep solar customers on the grid.

"The engineering reality is once we get too much solar in a certain space it does start to cause technical issues," he said.

"If there is too much energy coming back up the system in the middle of the day, it can cause frequency voltage disturbances in the system, which can lead to transformers tripping off to protect themselves from being damaged and that will cause localised blackouts.

"There are pockets of the grid already where we have significant penetration and we are starting to see technical issues."

However, he acknowledges that excess solar power has yet to cause any blackouts, or damage electricity infrastructure.

"I don't buy that at all," he said.

"It can be that in some suburbs or parts of suburbs a high penetration of solar on the point of use can raise voltage, these issues generally can be dealt with quickly.

"The critical issue is think where you are getting that perspective from. It is from an industry whose underlying market is threatened by customers doing it for themselves through peer-to-peer energy models. So, think with some critical insight to these claims."

He said when too many people rely on solar it threatens the very business model of the companies that own Australia's poles and wires.

"When the customers use the network less to buy centrally produced electricity, they ship less product," he said.

"When they ship less product, their underlying business is undermined, they need to charge more to the customers left and that leads to what has been called a death spiral.

"We are seeing rapid reductions in consumption at the point of use per household."

But Mr Dillon denies the distributors are acting out of self-interest.

"I absolutely reject that claim," he said.

"[What] we, as networks, have an interest in is running a safe network, running a reliable network, enabling the transition to a low carbon future and doing all that while keeping costs down as much as possible."

Solar installers say the networks are holding back business

Around Australia the poles and wires companies can decide which solar systems can connect to the grid.

Small systems can connect automatically, but in some areas, those wanting a larger system can find themselves caught up in red tape.

The vice-president of the Australian Solar Council, Glen Morris, said these limitations were holding back solar installation businesses and preventing the take-up of new battery storage technology.

"If you've already got a five kilowatt system, your house is full as far as the network is concerned," Mr Morris said.

"You go to add a battery, that's another five kilowatts and so they say no you're already full … so you can't add storage to your solar system."

The powers that be are stumbling in the dark to prevent a looming energy crisis, as the grid seeks to balance renewables' hidden challenges and competing demands.

Mr Morris also said the networks had the capacity to solve the problem of any excess solar flows into the grid, and infrastructure upgrades were not necessary.

"They already have the capability to turn off your solar invertor whenever they feel like it," he said.

"If they choose to connect that functionality, it's there in the inverter. The customer already has it."

ENA has acknowledged there is frustration with rooftop system size limits in the solar industry.

"What we are seeing is solar installers and others slightly frustrated at different requirements for different networks and sometimes they are unclear on the reasons for that," Mr Dillon said.

"Limitations are in place across the country to keep the lights on and make sure the network stays safe and we don't have sudden rushes of people connecting to the grid that causes outage issues."

But Mr Mountain is unconvinced, calling the limitations "somewhat spurious".

"The published, documented, critically reviewed analyses are few and far between, so it is very easy for engineers to make these arguments and those in policy circles only have so much tolerance for the detail," he said.

Hong Kong to expect electricity bills to rise 1 or 2 per cent

Hong Kong Electricity Tariff Increase reflects a projected 1-2% rise as HK Electric and CLP Power shift to cleaner fuel and natural gas, expand gas-fired units and LNG terminals, and adjust the fuel clause charge.

 

Key Points

An expected 1-2% 2018 rise from cleaner fuel, natural gas projects, asset growth, and shrinking fuel cost surpluses.

✅ Expected 1-2% rise amid cleaner fuel and gas shift

✅ Fuel clause charge and asset expansion pressure prices

✅ HK Electric and CLP Power urged to use surpluses prudently

 

Hong Kong customers have been asked to expect higher electricity bills next year, as seen with BC Hydro rate increases in Canada, with a member of a government panel on energy policy anticipating an increase in tariffs of one or two per cent.

The environment minister, Wong Kam-sing, also hinted they should be prepared to dig deeper into their pockets for electricity, as debates over California electric bills illustrate, in the wake of power companies needing to use more expensive but cleaner fuel to generate power in the future.

The city’s two power companies, HK Electric and CLP Power, are to brief lawmakers on their respective annual tariff adjustments for 2018, amid Ontario electricity price pressures drawing international attention, at a Legislative Council economic development panel meeting on Tuesday.

HK Electric supplies electricity to Hong Kong Island and neighbouring Lamma Island and Ap Lei Chau, while CLP Power serves Kowloon and the New Territories, including Lantau Island.

Wong said on Monday: “We have to appreciate that when we use cleaner fuel, there is a need for electricity tariffs to keep pace. I believe it is the hope of mainstream society to see a low-carbon and healthier environment.”

But he declined to comment on how much the tariffs might rise.

World Green Organisation chief executive William Yu Yuen-ping, also a member of the Energy Advisory Committee, urged the companies to better use their “overflowing” surpluses in their fuel cost recovery accounts.

Tariffs are comprised of two components: a basic amount reflecting a company’s operating costs and investments, and the fuel clause charge, which is based on what the company projects it will pay for fuel for the year.

Critics have claimed the local power suppliers routinely overestimate their fuel costs and amass huge surpluses.

In recent years, the two managed to freeze or cut their tariffs thanks to savings from lower fuel costs. Last year, HK Electric offered special rebates to its customers, which saw its tariff drop by 17.2 per cent. CLP Power froze its own charge for 2017.

Yu said the two companies should use the surpluses “more carefully” to stabilise tariffs.

“We estimate a big share of the surplus has been used up and so the honeymoon period is over.”

Based on his group’s research, Yu believed the tariffs would increase by one or two per cent.

Economist and fellow committee member Billy Mak Sui-choi said the expansion of the power companies’ fixed asset bases, such as building new gas-fired units and offshore liquefied natural gas terminals, a pattern reflected in Nova Scotia's 14% rate hike recently approved by regulators, would also cause tariffs to rise.

To fight climate change and improve air quality, the government has pledged to cut carbon intensity by between 50 and 60 per cent by 2020. Officials set a target of boosting the use of natural gas for electricity generation to half the total fuel mix from 2020.

Both power companies are privately owned and monitored by the government through a mutually agreed scheme of control agreements, akin to oversight seen under the UK energy price cap in other jurisdictions. These require the firms to seek government approval for their development plans, including their projected basic tariff levels.

At present, the permitted rate of return on their net fixed assets is 9.99 per cent. The deals are due to expire late next year.

Earlier this year, officials reached a deal with the two companies on the post-2018 scheme, settling on a 15-year term. The new agreements slash their permitted rate of return to 8 per cent.
