LARGE-SCALE ENERGY PROJECTS UNDERWAY IN NY

Manitoba Hydro rate hikes face public hearings over electricity rates, utility bills, and debt, with impacts on low-income households, Indigenous communities, and Winnipeg services amid credit rating pressure and rising energy costs.

Key Points

Manitoba Hydro seeks 7.9% annual increases to stabilize finances and debt, impacting electricity costs for households.

✅ Proposed hikes: 7.9% yearly through 2023/24

✅ Driven by debt, credit rating declines, rising interest

✅ Disproportionate impact on low-income and Indigenous communities

Hearings began Monday into Manitoba Hydro’s request for consecutive annual rate hikes of 7.9 per cent.  The crown corporation is asking for the steep hikes to commence April 1, 2018.

The increases would continue through 2023/2024, under a multi-year rate plan before dropping to what Hydro calls “sustainable” levels.

Patti Ramage, legal counsel for Hydro, said while she understands no one welcomes the “exceptional” rate increases, the company is dealing with exceptional circumstances.

It’s the largest rate increase Hydro has ever asked for, though a scaled-back increase was discussed later, saying rising debt and declining credit ratings are affecting its financial stability.

President and CEO Kelvin Shepherd said Hydro is borrowing money to fund its interest payments, and acknowledged that isn’t an effective business model.

Hydro’s application states that it will be spending up to 63 per cent of its revenue on paying financial expenses if the current request for rate hikes is not approved.

If it does get the increase it wants, that number could shrink to 45 per cent – which Ramage says is still quite high, but preferable to the alternative.

She cited the need to take immediate action to fix Hydro’s finances instead of simply hoping for the best.

“The worst thing we can do is defer action… that’s why we need to get this right,” Ramage said.

A number of intervenors presented varying responses to Hydro’s push for increased rates, with many focusing on how the hikes would affect Manitobans with lower incomes.

Senwung Luk spoke on behalf of the Assembly of Manitoba Chiefs, and said the proposed rates would hit First Nations reserves particularly hard.

He noted that 44.2 per cent of housing on reserves in the province needs significant improvement, which means electricity use tends to be higher to compensate for the lower quality of infrastructure.

Luk says this problem is compounded by the higher rates of poverty in Indigenous populations, with 76 per cent of children on reserves in Manitoba living below the poverty line.

If the increase goes forward, he said the AMC hopes to see a reduced rate for those living on reserves, despite a recent appeal court ruling on such pricing.

Byron Williams, speaking on behalf of the Consumers Coalition, said the 7.9 per cent increase unreasonably favours the interests of Hydro, and is unjustly biased against virtually everyone else.

In Saskatchewan, the NDP criticized an SaskPower 8 per cent rate hike as unfair to customers, highlighting regional concerns.

Williams said customers using electric space heating would be more heavily targeted by the rate increase, facing an extra $13.14 a month as opposed to the $6.88 that would be tacked onto the bills of those not using electric space heating.

Williams also called Hydro’s financial forecasts unreliable, bringing the 7.9 per cent figure into question.

Lawyer George Orle, speaking for the Manitoba Keewatinowi Okimakanak, said the proposed rate hikes would “make a mockery” of the sacrifices made by First Nations across the province, given that so much of Hydro’s infrastructure is on Indigenous land.

The city of Winnipeg also spoke out against the jump, saying property taxes could rise or services could be cut if the hikes go ahead to compensate for increased, unsustainable electricity costs.

In British Columbia, a BC Hydro 3 per cent increase also moved forward, drawing attention to affordability.

A common theme at the hearing was that Hydro’s request was not backed by facts, and that it was heading towards fear-mongering.

Manitoba Hydro’s CEO begged to differ as he plead his case during the first hearing of a process that is expected to take 10 weeks.

EV Charging Infrastructure Incentives are expanding as utilities fund public chargers, Level 2 networks, DC fast charging, grid-managed off-peak programs, and equitable access across Ohio, New Jersey, and Florida to accelerate clean transportation.

Key Points

Utility-backed programs funding Level 2 and DC fast chargers, managing grid demand, and expanding EV equity.

✅ Incentives for Level 2 and DC fast public charging stations.

✅ Grid-friendly off-peak charging to balance demand.

✅ Equity targets place chargers in low-income communities.

Electric providers in Florida, Ohio and New Jersey recently announced plans to expand electric vehicle charging networks and infrastructure through various incentive programs that could add thousands of new public chargers in the next several years.

Elsewhere, utilities are advancing similar efforts, with Michigan EV programs proposing more than $20 million for charging infrastructure to accelerate adoption.

American Electric Power in Ohio will offer nearly $10 million in incentives toward the build out of 375 EV charging stations throughout the company's service territory, which largely includes Columbus.

Meanwhile, the Public Service Electric and Gas Company (PSE&G), an electric utility provider in New Jersey, has proposed a six-year plan to support the development of nearly 40,000 electric vehicle chargers across a wide range of customers and sectors, said Francis Sullivan, a spokesperson for PSE&G.

And Duke Energy in Florida is installing up to 530 EV charging stations across its service area, as part of its Park and Plug pilot program, which will be making the charging ports available in multifamily housing complexes, workplaces and other high traffic areas.

"We are bringing cleaner energy to Florida through 700 megawatts of new universal solar, and we are helping our customers to bring clean transportation to the state as well," Catherine Stempien, Duke Energy Florida president, said in a statement. "We are committed to providing smarter, cleaner energy alternatives for all our customers."

The project in Ohio is making incentive funding available to government organizations, multifamily housing developments and workplaces, covering from 50 percent to all of the costs. The plan, to be rolled out in the next four years, aims to incentivize the development of 300 level-two chargers and 75 "fast chargers" capable of charging a car's battery in minutes rather than hours.

"I think what's interesting about what we're seeing now in the industry is that electric vehicles and electric vehicle charging are expanding beyond California, and like other Pacific Coast states," said Scott Fisher, vice president of marketing at Greenlots, maker of car chargers and software. Greenlots has been selected as one of the companies to provide the chargers for the AEP project.

California has occupied the lion's share of the electric vehicle market, making up about 5 percent of the cars on the state's highways. The U.S. market sits at about 1.5 percent. However, indications show the EV boom may be set to take off as more models are being rolled out, and prices are making the electric cars more competitive with their gas-powered counterparts. The group Securing America's Future Energy (SAFE) announced the one-millionth electric vehicle is on course to be sold in the United States this month.

In a statement, Ben Prochazka, vice president of the Electrification Coalition, an EV advocacy group, called this "a major milestone and brings us one step closer to reducing our transportation system's dependence on oil. This is a direct result of the tireless efforts by communities and advocates throughout the 'EV ecosystem.'"

In New Jersey, PSE&G's efforts -- which are part of the company's proposed Clean Energy Future program -- will not only focus on building out the charging infrastructure, but structure car recharging to control charging and encourage residents to charge their cars during off-peak times.

"For now, with a modest number of charging stations in the market, it's not a huge problem. But over time, as you're putting in many thousands of these stations, what you want to make sure is that those stations are operating in sync with state power grids, where you don't have people all charging at the same time at like 5 p.m. on a hot summer day," said Fisher.

PSE&G also plans to offer incentives to encourage the development of level-two chargers and DC fast-chargers, as well as "provide grants and incentives for 100 electric school buses and EV charging infrastructure at school districts in PSE&G's service territory," said Sullivan.

"PSE&G will also help fund electrification projects at customer locations such as ports, airports and transit facilities," Sullivan added, via email.

Utilities and transportation planners are also keeping the concept of equity in mind -- to ensure EVs are adopted by more than just the Tesla owner -- and will also focus on placing infrastructure in low-income areas.

"Ten percent of the stations will be in low income areas, defined by census blocks," said Scott Blake, a communications consultant at AEP in Columbus.

Duke Energy also announced 10 percent of the chargers it is installing in Florida will be in "income-qualified communities," according to a company press release.

Smart solar inverters anchor DER communications and control, meeting IEEE 1547 and California Rule 21 for volt/VAR, reactive power, and ride-through, expanding hosting capacity and enabling grid services via secure real-time telemetry and commands.

Key Points

Smart solar inverters use IEEE 1547, volt/VAR and reactive power to stabilize circuits and integrate DER safely.

✅ Meet IEEE 1547, Rule 21 ride-through and volt/VAR functions

✅ Support reactive power to manage voltage and hosting capacity

✅ Enable utility communications, telemetry, and grid services

Advanced solar inverters could be one of the biggest distributed energy resource communications and control points out there someday. With California now requiring at least early-stage “smart” capabilities from all new solar projects — and a standards road map for next-stage efforts like real-time communications and active controls — this future now has a template.

There are still a lot of unanswered questions about how smart inverters will be used.

That was the consensus at Intersolar this week, where experts discussed the latest developments on the U.S. smart solar inverter front. After years of pilot projects, multi-stakeholder technical working groups, and slow and steady standards development, solar smart inverters are finally starting to hit the market en masse — even if it’s not yet clear just what will be done with them once they’re installed.

“From the technical perspective, the standards are firm,” Roger Salas, distribution engineering manager for Southern California Edison, said. In September of last year, his utility started requiring that all new solar installations come with “Phase 1" advanced inverter functionality, as defined under the state’s Rule 21.

Later this month, it’s going to start requiring “reactive power priority” for these inverters, and in February 2019, it’s going to start requiring that inverters support the communications capabilities described in “Phase 2,” as well as some more advanced “Phase 3” capabilities.

Increasing hosting capacity: A win-win for solar and utilities

Each of these phases aligns with a different value proposition for smart inverters. The first phase is largely preventative, aimed at solving the kinds of problems that have forced costly upgrades to how inverters operate in solar-heavy Germany and Hawaii.

The key standard in question in the U.S. is IEEE 1547, which sets the rules for what grid-connected DERs must do to stay safe, such as trip offline when the grid goes down, or avoid overloading local transformers or circuits.

The old version of the standard, however, had a lot of restrictive rules on tripping off during relatively common voltage excursions, which could cause real problems on circuits with a lot of solar dropping off all at once.

Phase 1 implementation of IEEE 1547 is all about removing these barriers, Salas said. “They need to be stable, they need to be connected, they need to be able to support the grid.”

This should increase hosting capacity on circuits that would have otherwise been constrained by these unwelcome behaviors, he said.

Reactive power: Where utility and solar imperatives collide

The old versions of IEEE 1547 also didn’t provide rules for how inverters could use one of their more flexible capabilities: the ability to inject or absorb reactive power to mitigate voltage fluctuations, including those that may be caused by the PV itself. The new version opens up this capability, which could allow for an active application of reactive power to further increase hosting capacity, as well as solve other grid edge challenges for utilities.

But where utilities see opportunity, the solar industry sees a threat. Every unit of reactive power comes at the cost of a reduction in the real power output of solar inverters — and almost every solar installation out there is paid based on the real power it produces.

“If you’re tasked to do things that rob your energy sales, that will reduce compensation,” noted Ric O'Connell, executive director of the Oakland, Calif.-based GridLab. “And a lot of systems have third-party owners — the Sunruns, the Teslas — with growing Powerwall fleets — that have contracts, performance guarantees, and they want to get those financed. It’s harder to do that if there’s uncertainty in the future with curtailment."

“That’s the bottleneck right now,” said Daniel Munoz-Alvarez, a GTM Research grid edge analyst. “As we develop markets on the retail end for ...volt/VAR control to be compensated on the grid edge and that is compensated back to the customer, then the customer will be more willing to allow the utility to control their smart inverters or to allow some automation.”

But first, he said, “We need some agreed-upon functions.”

The future: Communications, controls and DER integration

The next stage of smart inverter functionality is establishing communications with the utility. After that, utilities will be able use them to monitor key DER data, or issue disconnect and reconnect commands in emergencies, as well as actively orchestrate other utility devices and systems through emerging virtual power plant strategies across their service areas.

This last area is where Salas sees the greatest opportunity to putting mass-market smart solar inverters to use. “If you want to maximize the DERs and what they can do, the need information from the grid. And DERs provide operational and capability information to the utility.”

Inverter makers have already been forced by California to enable the latest IEEE 1547 capabilities into their existing controls systems — but they are clearly embracing the role that their devices can play on the grid as well. Microinverter maker Enphase leveraged its work in Hawaii into a grid services business, seeking to provide data to utilities where they already had a significant number of installations. While Enphase has since scaled back dramatically, its main rival SolarEdge has taken up the same challenge, launching its own grid services arm earlier this summer.

Inverters have been technically capable of doing most of these things for a long time. But utilities and regulators have been waiting for the completion of IEEE 1547 to move forward decisively. Patrick Dalton, senior engineer for Xcel Energy, said his company’s utilities in Colorado and Minnesota are still several years away from mandating advanced inverter capabilities and are waiting for California’s energy transition example in order to choose a path forward.

In the meantime, it’s possible that Xcel's front-of-meter volt/VAR optimization investments in Colorado, including grid edge devices from startup Varentec, could solve many of the issues that have been addressed by smart inverter efforts in Hawaii and California, he noted.

The broader landscape for rolling out smart inverters for solar installations hasn’t changed much, with Hawaii and California still out ahead of the pack, while territories such as Puerto Rico microgrid rules evolve to support resilience. Arizona is the next most important state, with a high penetration of distributed solar, a contentious policy climate surrounding its proper treatment in future years, and a big smart inverter pilot from utility Arizona Public Service to inform stakeholders.

All told, eight separate smart inverter pilots are underway across eight states at present, according to GTM Research: Pacific Gas & Electric and San Diego Gas & Electric in California; APS and Salt River Project in Arizona; Hawaiian Electric in Hawaii; Duke Energy in North Carolina; Con Edison in New York; and a three-state pilot funded by the Department of Energy’s SunShot program and led by the Electric Power Research Institute.

BC Hydro Time-of-Use Rates propose off-peak credits and peak surcharges, with 5 cent/kWh differentials, encouraging demand shifting, EV charging at night, and smart meter adoption, pending BC Utilities Commission review in an optional opt-in program.

Key Points

Optional pricing that credits 5 cents/kWh off-peak and adds 5 cents/kWh during 4-9 p.m. peak to encourage load shifting.

✅ Off-peak credit: 11 p.m.-7 a.m., 5 cents/kWh savings

✅ Peak surcharge: 4-9 p.m., additional 5 cents/kWh

✅ Opt-in only; BCUC review; suits EV charging and flexible loads

BC Hydro is looking to charge customers less for electricity during off peak hours and more during the busiest times of the day, reflecting holiday electricity demand as well.

The BC Utilities Commission is currently reviewing the application that if approved would see customers receive a credit of 5 cents per kilowatt hour for electricity used from 11 p.m. to 7 a.m.

Customers would be charged an additional 5 cents per kWh for electricity used during the on-peak period from 4 p.m. to 9 p.m., and in Ontario, there were no peak-rate cuts for self-isolating customers during early pandemic response.

There would be no credit or additional charge will be applied to usage during the off-peak period from 7 a.m. to 4 p.m. and 9 p.m. to 11 p.m.

“We know the way our customers are using power is changing and they want more options,” BC Hydro spokesperson Susie Rieder said.

“It is optional and we know it may not work for everyone.”

For example, if a customer has an electric vehicle it will be cheaper to plug the car in after 9 p.m., similar to Ontario's ultra-low overnight plan offerings, rather than immediately after returning home from a standard work day.

If approved, the time of use rates would only apply to customers who opt in to the program, whereas Ontario provided electricity relief during COVID-19.

During the pandemic, Ontario extended off-peak electricity rates to help households and small businesses.

The regulatory review process is expected to take about one year.

Other jurisdictions, including Ontario's ultra-low overnight pricing, currently offer off peak rates. One of the challenges is that consumers change in hopes of altering their behaviour, but in reality, end up paying more.

“The cheapest electrical grid system is one with consistent demand and the issue of course is our consumption is not flat,” energyrates.ca founder Joel MacDonald said.

“There is a 5 cent reduction in off peak times, there is a 5 cent increase in peak times, you would have to switch 50 per cent of your load.”

ICT Electricity Demand is surging as data centers, 5G, IoT, and server farms expand, straining grids, boosting carbon emissions, and challenging climate targets unless efficiency, renewable energy, and smarter cooling dramatically improve.

Key Points

ICT electricity demand is power used by networks, devices, and data centers across the global communications sector.

✅ Projected to reach up to 20 percent of global electricity by 2025

✅ Driven by data centers, 5G traffic, IoT, and high-res streaming

✅ Mitigation: efficiency, renewable PPAs, advanced cooling, workload shifts

The communications industry could use 20% of all the world’s electricity by 2025, hampering attempts to meet climate change targets, even as countries like New Zealand's electrification plans seek broader decarbonization, and straining grids as demand by power-hungry server farms storing digital data from billions of smartphones, tablets and internet-connected devices grows exponentially.

The industry has long argued that it can considerably reduce carbon emissions by increasing efficiency and reducing waste, but academics are challenging industry assumptions. A new paper, due to be published by US researchers later this month, will forecast that information and communications technology could create up to 3.5% of global emissions by 2020 – surpassing aviation and shipping – and up to 14% 2040, around the same proportion as the US today.

Global computing power demand from internet-connected devices, high resolution video streaming, emails, surveillance cameras and a new generation of smart TVs is increasing 20% a year, consuming roughly 3-5% of the world’s electricity in 2015, says Swedish researcher Anders Andrae.

In an update o a 2016 peer-reviewed study, Andrae found that without dramatic increases in efficiency, the ICT industry could use 20% of all electricity and emit up to 5.5% of the world’s carbon emissions by 2025. This would be more than any country, except China, India and the USA, where China's data center electricity use is drawing scrutiny.

He expects industry power demand to increase from 200-300 terawatt hours (TWh) of electricity a year now, to 1,200 or even 3,000TWh by 2025. Data centres on their own could produce 1.9 gigatonnes (Gt) (or 3.2% of the global total) of carbon emissions, he says.

“The situation is alarming,” said Andrae, who works for the Chinese communications technology firm Huawei. “We have a tsunami of data approaching. Everything which can be is being digitalised. It is a perfect storm. 5G [the fifth generation of mobile technology] is coming, IP [internet protocol] traffic is much higher than estimated, and all cars and machines, robots and artificial intelligence are being digitalised, producing huge amounts of data which is stored in data centres.”

US researchers expect power consumption to triple in the next five years as one billion more people come online in developing countries, and the “internet of things” (IoT), driverless cars, robots, video surveillance and artificial intelligence grows exponentially in rich countries.

The industry has encouraged the idea that the digital transformation of economies and large-scale energy efficiencies will slash global emissions by 20% or more, but the scale and speed of the revolution has been a surprise.

Global internet traffic will increase nearly threefold in the next five years says the latest Cisco Visual Networking Index, a leading industry tracker of internet use.

“More than one billion new internet users are expected, growing from three billion in 2015 to 4.1bn by 2020. Over the next five years global IP networks will support up to 10bn new devices and connections, increasing from 16.3bn in 2015 to 26bn by 2020,” says Cisco.

A 2016 Berkeley laboratory report for the US government estimated the country’s data centres, which held about 350m terabytes of data in 2015, could together need over 100TWh of electricity a year by 2020. This is the equivalent of about 10 large nuclear power stations.

Data centre capacity is also rocketing in Europe, where the EU's plan to double electricity use by 2050 could compound demand, and Asia with London, Frankfurt, Paris and Amsterdam expected to add nearly 200MW of consumption in 2017, or the power equivalent of a medium size power station.

“We are seeing massive growth of data centres in all regions. Trends that started in the US are now standard in Europe. Asia is taking off massively,” says Mitual Patel, head of EMEA data centre research at global investment firm CBRE.

“The volume of data being handled by such centres is growing at unprecedented rates. They are seen as a key element in the next stage of growth for the ICT industry”, says Peter Corcoran, a researcher at the university of Ireland, Galway.

Using renewable energy sounds good but no one else benefits from what will be generated, and it skews national attempts to reduce emissions

Ireland, which with Denmark is becoming a data base for the world’s biggest tech companies, has 350MW connected to data centres but this is expected to triple to over 1,000MW, or the equivalent of a nuclear power station size plant, in the next five years.

Permission has been given for a further 550MW to be connected and 750MW more is in the pipeline, says Eirgrid, the country’s main grid operator.

“If all enquiries connect, the data centre load could account for 20% of Ireland’s peak demand,” says Eirgrid in its All-Island Generation Capacity Statement 2017-2026  report.

The data will be stored in vast new one million square feet or larger “hyper-scale” server farms, which companies are now building. The scale of these farms is huge; a single $1bn Apple data centre planned for Athenry in Co Galway, expects to eventually use 300MW of electricity, or over 8% of the national capacity and more than the daily entire usage of Dublin. It will require 144 large diesel generators as back up for when the wind does not blow.

Pressed by Greenpeace and other environment groups, large tech companies with a public face , including Google, Facebook, Apple, Intel and Amazon, have promised to use renewable energy to power data centres. In most cases they are buying it off grid but some are planning to build solar and wind farms close to their centres.

Greenpeace IT analyst Gary Cook says only about 20% of the electricity used in the world’s data centres is so far renewable, with 80% of the power still coming from fossil fuels.

“The good news is that some companies have certainly embraced their responsibility, and are moving quite aggressively to meet their rapid growth with renewable energy. Others are just growing aggressively,” he says.

Architect David Hughes, who has challenged Apple’s new centre in Ireland, says the government should not be taken in by the promises.

“Using renewable energy sounds good but no one else benefits from what will be generated, and it skews national attempts to reduce emissions. Data centres … have eaten into any progress we made to achieving Ireland’s 40% carbon emissions reduction target. They are just adding to demand and reducing our percentage. They are getting a free ride at the Irish citizens’ expense,” says Hughes.

Eirgrid estimates indicate that by 2025, one in every 3kWh generated in Ireland could be going to a data centre, he added. “We have sleepwalked our way into a 10% increase in electricity consumption.”

Fossil fuel plants may have to be kept open longer to power other parts of the country, and manage issues like SF6 use in electrical equipment, and the costs will fall on the consumer, he says. “We will have to upgrade our grid and build more power generation both wind and backup generation for when the wind isn’t there and this all goes onto people’s bills.”

Under a best case scenario, says Andrae, there will be massive continuous improvements of power saving, as the global energy transition gathers pace, renewable energy will become the norm and the explosive growth in demand for data will slow.

But equally, he says, demand could continue to rise dramatically if the industry keeps growing at 20% a year, driverless cars each with dozens of embedded sensors, and cypto-currencies like Bitcoin which need vast amounts of computer power become mainstream.

“There is a real risk that it all gets out of control. Policy makers need to keep a close eye on this,” says Andrae.

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.

Rise after fall in Hong Kong electricity use linked to subsidies

“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.
