How IRENA Study Will Resolve Philippines’ Electricity Crisis

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.

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.

Alberta Data Centers fuel the digital economy with cloud computing, AI, and streaming, leveraging renewable energy and low-cost power; yet grid capacity, sustainability, efficient cooling, and regulatory frameworks remain critical considerations for reliable growth.

Key Points

Alberta facilities for cloud, AI, and digital services, balancing energy demand, renewable power, and grid reliability.

✅ Low electricity costs and renewables attract hyperscale builds

✅ Grid upgrades needed to meet rising, 24/7 workloads and cooling

✅ Workforce training aligns with IT, HVAC, and electrical roles

As Alberta continues to evolve its energy landscape, the recent surge in data center projects is making headlines. With companies investing heavily in this sector, Alberta is positioning itself as a key player in the digital economy. This trend, however, brings both opportunities and challenges that need careful consideration.

The Digital Economy Boom

Data centers are essential for supporting the growing demands of the digital economy, which includes everything from cloud computing to streaming services and artificial intelligence. As businesses increasingly rely on digital infrastructure, the need for reliable and efficient data centers has skyrocketed. Alberta has become an attractive destination for these facilities due to its relatively low electricity costs, abundant renewable energy resources, and favorable regulatory environment, according to a 2023 clean grids outlook that highlighted the province.

The influx of major tech companies establishing data centers in Alberta not only promises job creation but also contributes to the provincial economy. With investments pouring in, local businesses may see increased opportunities for partnerships, supplies, and services, ultimately benefiting the broader economic landscape, though proposed market changes could influence procurement and siting decisions.

Energy Demand and Infrastructure

While the growth of data centers can drive economic benefits, it also raises important questions about energy demand and infrastructure capacity, questions that have intensified since Kenney-era electricity changes in the sector. Data centers are energy-intensive, often requiring significant amounts of electricity to operate and cool their servers. As these facilities multiply, they will place additional pressure on Alberta's power grid.

The province has made strides in transitioning to renewable energy sources, with a defined path to clean electricity that aligns well with the goals of many data center operators seeking to reduce their carbon footprint. However, the challenge lies in ensuring that the electricity grid can meet the increasing demand without compromising reliability. The integration of more renewable energy into the grid requires careful planning and investment in infrastructure to handle variable supply and maintain a stable energy flow.

Environmental Concerns

The environmental implications of expanding data centers are also a point of concern. While many tech companies prioritize sustainability and aim for carbon neutrality, the reality is that increased energy consumption can contribute to greenhouse gas emissions if not managed properly, especially when regional export restrictions constrain low-carbon power flows. Alberta’s reliance on fossil fuels for a significant portion of its energy supply raises questions about how these data centers will impact the province's climate goals.

To address these concerns, there is a need for policies that encourage the use of renewable energy sources specifically for data center operations. Incentives for companies to invest in green technologies, such as energy-efficient cooling systems or on-site renewable energy generation, could help mitigate the environmental impact.

Workforce Development

Another critical aspect of this data center boom is the potential for job creation. Data centers require a range of skilled workers, from IT professionals to engineers and maintenance staff. However, there is a pressing need for workforce development initiatives to ensure that Albertans are equipped with the necessary skills to fill these roles.

Educational institutions and training programs must adapt to the changing demands of the job market. Collaborations between tech companies and local colleges can foster specialized training programs that prepare workers for careers in this evolving sector. By investing in workforce development, Alberta can maximize the benefits of data center growth while ensuring that its residents are prepared for the jobs of the future.

The Future of Alberta's Data Center Landscape

Looking ahead, Alberta’s data center landscape is poised for continued growth. The province's commitment to diversifying its economy, coupled with its abundant energy resources, makes it an appealing choice for tech companies. However, as the industry expands, careful consideration must be given to energy management, environmental impact, and workforce readiness, especially as Alberta changes how it produces and pays for electricity.

Regulatory frameworks will play a crucial role in shaping the future of data centers in Alberta, as the province pursues a market overhaul that could affect costs and reliability. Policymakers will need to balance the interests of businesses, environmental concerns, and the need for a reliable energy supply. By creating a supportive environment for innovation while addressing these challenges, Alberta can emerge as a leader in the digital economy.

The rise of data centers in Alberta marks an exciting chapter in the province's economic evolution. With the potential for job creation, technological advancement, and economic diversification, the opportunities are significant. However, it is essential to navigate the associated challenges thoughtfully. By prioritizing sustainability, infrastructure investment, and workforce development, Alberta can harness the full potential of this burgeoning sector, positioning itself as a key player in the global digital landscape.

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.

Maryland Community Solar Program enables renters and condo residents to subscribe to offsite solar, earn utility bill discounts, and support projects across BGE, Pepco, Delmarva, and Potomac Edison territories, with low to moderate income participation.

Key Points

A pilot allowing residents to subscribe to offsite solar and get bill credits and savings, regardless of home ownership.

✅ 5-10 percent discounts on standard utility rates

✅ Available in BGE, Pepco, Delmarva, Potomac Edison areas

✅ Includes low and moderate income subscriber carve-outs

Maryland has launched a pilot program that will allow anyone to power their home with solar panels — even if they are renters or condo-dwellers, or live in the shade of trees.

Solar developers are looking for hundreds of residents to subscribe to six power projects planned across the state, including recently announced sites in Owings Mills and Westminster. Their offers include discounts on standard electric rates.

The developers need a critical mass of customers who are willing to buy the projects’ electricity before they can move forward with plans to install solar panels on about 80 acres. Under state rules, the customer base must include low- and moderate-income residents, many of whom face energy insecurity challenges.

The idea of the community solar program is to tap into the pool of residential customers who don’t want to get their energy from fossil fuels but currently have no way to switch to a cleaner alternative.

That could significantly expand demand for solar projects, said Gary Skulnik, a longtime Maryland solar entrepreneur.

Skulnik is now CEO of Neighborhood Sun, a company recruiting customers for the six projects.

“You’re signing up for a project that won’t exist unless we get enough subscribers,” Skulnik said. “You’re actually getting a new project built.”

It could also stoke simmering conflicts over what sort of land is appropriate for solar development.

The General Assembly authorized the community solar pilot program in 2015. But not-in-my-backyard opposition and concerns about the loss of agricultural land have slowed progress.

Community solar could force more communities to confront those sorts of clashes — and to consider more carefully where solar farms belong.

“We are going to see a lot more solar development in the state,” said Megan Billingsley, assistant director of the Valleys Planning Council in Baltimore County. “One of the things we haven’t seen is any direction or thoughtful planning on where we want to see solar development.”

The General Assembly authorized about 200 megawatts in community solar projects — enough to power about 40,000 households — over three years.

Customers can sign up for projects built within the territory of their electric utility. About half of that solar energy load has been allotted for the region served by Baltimore Gas and Electric Co.

By subscribing to a community solar project, customers won’t actually be getting their electricity from its photovoltaic panels. But their payments will help finance it and, in some cases, complementary battery storage solutions as well.

The Public Service Commission has approved six projects so far: Two in BGE territory, in Owings Mills and near Westminster; one in Pepco territory, in Prince George’s County; two in Delmarva Power and Light territory, in Caroline and Worcester counties; and one in Potomac Edison territory, in Washington County where planning officials have developed proposed recommendations.

More projects are expected to win approval in the next two years.

But none of them can be built unless they catch on with electricity customers. The developers are looking for 2,600 customers statewide.

Skulnik would not say how many customers an individual project needs to get the green light. But he said that the Prince George’s proposal, a 25-acre array atop a Fort Washington landfill is the closest, with about 100 subscribers so far.

The terms of subscription vary by project, but discounts range from 5 percent to 10 percent off utility rates. Customers are asked to commit to the projects for as long as 25 years. (They can break the contracts with advance notice, or if they move to a different utility service area.)

Maryland joins more than a dozen states in advancing community solar projects, as scientists work to improve solar and wind power technology.

Corey Ramsden is an executive for Solar United Neighbors, a nonprofit that promotes the solar industry in eight states and the District of Columbia.

He said potential customers are often confused by the mechanics of subscribing to community solar, or hesitant to commit for years or even decades. The industry is working to answer questions and get people more comfortable with the idea, he said.

But it has been a challenge across the country, including debates over New England grid upgrades, and in Maryland. Advocates for solar say there is broad support for renewable energy generation. The state has set goals to increase green energy use and reduce greenhouse gas emissions.

Still, many Marylanders don’t welcome the reality when a project attempts to move in.

Rural land is often the most desirable for solar developers, because it requires the least effort to prepare for an array of panels. But community groups in those areas have asked whether land historically used for farming is right for a more industrial use.

“People are very much in favor of going for a lot more renewables, for whatever reason,” said Dru Schmidt-Perkins, the former president of the land conservation group 1,000 Friends of Maryland. “That support comes to a screeching halt when land that is perceived to be valuable for other things, whether a historic view­shed or farming, suddenly becomes a target of a location for this new project.”

Such concerns have at least temporarily stalled the momentum for solar across the state. Anne Arundel County had at least five small community solar projects in the pipeline in December when officials decided to pause development for eight months. Baltimore County officials imposed a four-month moratorium on solar development before passing an ordinance last year to limit the size and number of solar farms.

Billingsley said the Valley Plannings Council, which advocates for historic and rural areas in western Baltimore County, is frustrated that there hasn’t been more discussion about which areas the county should target for solar development — and which it shouldn’t.

She said she fears that pressure to expand solar farms across rural lands is only going to grow as community solar projects launch, and as lawmakers in Annapolis talk about more policies to promote investment in renewable energy.

Schmidt-Perkins called community solar “an amazing program” for those who would install solar panels on their roofs if they could. But she said its launch heightens the importance of discussions about a broader solar strategy.

“Most communities are caught a little flat-footed on this and are somewhat at the mercy of an industry that’s chomping at the bit,” she said. “It’s time for Maryland to say, ‘Okay, let’s come up with our plan so that we know how much solar can we really generate in this state on lands that are not conflict-based.’”

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.
