Synchrophasors deliver PMU-based, real-time monitoring for the smart grid, helping NYISO prevent blackouts, cut costs, and integrate renewables, with DOE-backed deployments boosting reliability, situational awareness, and data sharing across regional partners.

 

Key Points

Synchrophasors, or PMUs, are grid sensors that measure synced voltage, current, and frequency to enhance reliability.

✅ Real-time grid visibility and situational awareness

✅ Early fault detection to prevent cascading outages

✅ Supports renewable integration and lowers operating costs

 

Have you ever heard of a synchrophasor? It may sound like a word out of science fiction, but these mailbox-sized devices are already changing the electrical grid as we know it.

The grid was born over a century ago, at a time when our needs were simpler and our demand much lower. More complex needs are putting a heavy strain on the aging infrastructure, which is why we need to innovate and update our grid with investments in a smarter electricity infrastructure so it’s ready for the demands of today.

That’s where synchrophasors come in.

A synchrophasor is a sophisticated monitoring device that can measure the instantaneous voltage, current and frequency at specific locations on the grid. This gives operators a near-real-time picture of what is happening on the system, including insights into power grid vulnerabilities that allow them to make decisions to prevent power outages.

Just yesterday I attended the dedication of the New York Independent System Operator's smart grid control center, a $75 million project that will use these devices to locate grid problems at an early stage and share these data with their regional partners. This should mean fewer blackouts for the State of New York. I would like to congratulate NYISO for being a technology leader.

And not only will these synchrophasors help prevent outages, but they also save money. By providing more accurate and timely data on system limits, synchrophasors make the grid more reliable and efficient, thereby reducing planning and operations costs and addressing grid modernization affordability concerns for utilities.

The Department has worked with utilities across the country to increase the number of synchrophasors five-fold -- from less than 200 in 2009 to over 1,700 today. And this is just a part of our commitment to making a smarter, more resilient grid a reality, reinforced by grid improvement funding from DOE.

In September 2013, the US Department of Energy announced up to $9 million in funding to facilitate rapid response to unusual grid conditions. As a result, utilities will be able to better detect and head off potential blackouts, while improving day-to-day grid reliability and helping with the integration of solar into the grid and other clean renewable sources.

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.”

Opinion: Would we use Site C's electricity?

Site C Dam Electricity Demand underscores B.C.'s decarbonization path, enabling electrification of EVs, heat pumps, and industry, aligning with BC Hydro forecasts and 2030/2050 GHG targets to supply dependable, renewable baseload power.

 

Key Points

Projected clean power tied to Site C, driven by B.C. electrification to meet 2030 and 2050 greenhouse gas targets.

✅ Aligns with 25-30% by 2030 and 55-70% by 2050 GHG cuts

✅ Supports EVs, heat pumps, and industrial electrification

✅ Provides dependable baseload alongside efficiency gains

 

There are valid reasons not to build the Site C dam. There are also valid reasons to build it. One of the latter is the rapid increase in clean electricity needed to reduce B.C.’s greenhouse gas emissions from burning natural gas, gasoline, diesel and other harmful fossil fuel products.

Although former Premier Christy Clark casually avoided near-term emissions targets, Prime Minister Justin Trudeau has set Canadian targets for both 2030 and 2050, and cleaning up Canada's electricity is critical to meeting them. Studies by my research group at Simon Fraser University and other independent analysts show that B.C.’s cost-effective contribution to these national targets requires us to reduce our emissions 25 to 30 per cent by 2030 and 55 to 70 per cent by 2050 — an energy evolution involving, among other things, a much greater use of electricity in buildings, vehicles and industry.

Recent submissions to the Site C hearing have offered widely different estimates of B.C.’s electricity demand in the decade after the project’s completion in 2025, some arguing the dam’s output will be completely surplus to domestic need for years and perhaps decades, even though improved B.C.-Alberta grid links could help balance regional demand. Some of this variation in demand forecasts is understandable. Industrial demand is especially difficult to predict, dependent as it is on global economic conditions and shifting trade relations. And there are legitimate uncertainties about B.C. Hydro’s ability to reduce electricity demand by promoting efficient products and behaviour through its Power Smart program. But some of the forecasts appear to be deliberate exaggerations, designed to support fixed positions for or against Site C.

Our university-based research team models the energy system changes required to meet national and provincial emissions targets, and we have been comparing estimates of the electricity demand implications. These estimates are produced by academics, as well as by key institutions like B.C. Hydro, the National Energy Board, and the governments of Canada and B.C.

Most electricity forecasts for B.C., including the most recent by B.C. Hydro, do not assume that B.C. reduces its greenhouse gas emissions by 25 to 30 per cent by 2030 and 55 to 70 per cent by 2050. When we adjust Hydro’s forecast for just the low end of these targets, we find that in its latest, August 30, submission to the Site C hearing, which followed the premier’s over-budget go-ahead on the project, Hydro has underestimated the demand for its electricity by about three terawatt-hours in 2025, four in 2030 and 10 in 2035. Hydro’s forecast indicates that it will need the five terawatt-hours from Site C. Our research shows that even if Hydro’s demand forecast is too high, appropriate climate policy nationally and in B.C. will absorb all the electricity the dam can produce soon after its completion.

B.C. Hydro does not forecast electricity demand to 2050. But, studies by us and others show that B.C. electricity demand will be almost double today’s levels if we are to reduce emissions by 55 to 70 per cent, even amid a documented risk of missing the 2050 target, in just over three decades while our population, economy, buildings and equipment grow significantly. Most mid- and small-sized vehicles will be electric. Most buildings will be well insulated and heated by electric resistance or electric heat-pumps, either individually or via district heating systems. And many low temperature industrial applications will be electric.

Aggressive efforts to promote energy efficiency will make an important contribution, such that energy demand will not grow nearly as fast as the economy. But it is delusional to think that humans will stop using energy. Even climate policy scenarios in which we assume unprecedented success with energy efficiency show dramatic increases in the consumption of electricity, this being the most favoured zero-emission form of energy as a replacement for planet-destroying gasoline and natural gas.

The completion of the Site C dam is a complicated and challenging societal choice, and delay-related cost risks highlighted by the premier underscore the stakes. There is unbiased evidence and argument supporting either completion or cancellation. But let’s stick to the unbiased evidence. In the case of our 2030 and 2050 greenhouse gas reduction targets, such evidence shows that we must substantially increase our generation of dependable electricity. If the Site C dam is built, and if we are true to our climate goals, all its electricity will be used in B.C. soon after completion.

The Rise of Data Centers in Alberta

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.

✅ Citywide smart grid cuts outages and energy loss

✅ 140 jobs; attracts clean tech and industry

 

PUC Distribution Inc. in Sault Ste. Marie is receiving $11.8 million from the federal government to invest in infrastructure, as utilities nationwide have faced pandemic-related losses that underscore the need for resilient systems.

The MP for the riding, Terry Sheehan, made the announcement on Monday.

The money will go to the utility's smart grid project, where technologies like a centralized SCADA system can enhance situational awareness and control.

"This smart grid project offers a glimpse into our clean energy future and represents a new wave of economic activity for the region," Sheehan said.

"Along with job creation, new industries will be attracted to a modern grid, supported by stable electricity pricing that helps competitiveness, all while helping the environment."

His office says the investment will allow the utility to reduce outages, provide more information to customers to help make smarter electricity use choices, aligned with Ontario's energy-efficiency programs that encourage conservation, and offer more services.

"This is an innovative project that makes Sault Ste. Marie a leader," mayor Christian Provenzano said.

"We will be the first city in our country to implement a community-wide smart grid. Once it is complete, the smart grid will make our energy infrastructure more reliable, reduce energy loss and lead to a more innovative economy for our community."

The project will also create 140 new jobs.

"As a community-focused utility, we are always looking for innovative ways to help our customers save money amid concerns about hydro disconnections during winter, and reduce their carbon footprint," Rob Brewster, president and CEO of PUC Distribution said.

"The investment the government has made in our community will not only help modernize our city's electrical distribution system [as] once the project is complete, Sault Ste. Marie will have access to an electricity grid that can handle the growing demands of a city in the 21st century."

New Rules for a Future Puerto Rico Microgrid Landscape

Puerto Rico Microgrid Regulations outline renewable energy, CHP, and storage standards, enabling islanded systems, PREPA interconnection, excess energy sales, and IRP alignment to boost resilience, distributed resources, and community power across the recovering grid.

 

Key Points

Rules defining microgrids, requiring 75 percent renewables or CHP, and setting interconnection and PREPA fee frameworks.

✅ 75 percent renewables or CHP; hybrids allowed

✅ Registration, engineer inspection, and annual generation reports

✅ PREPA interconnection fees; excess energy sales permitted

 

The Puerto Rico Energy Commission unveiled 29 pages of proposed regulations last week for future microgrid installations on the island.

The regulations, which are now open for 30 days of public comment, synthesized pages of responses received after a November 10 call for recommendations. Commission chair José Román Morales said it’s the most interest the not-yet four-year-old commission has received during a public rulemaking process.

The goal was to sketch a clearer outline for a tricky-to-define concept -- the term "microgrid" can refer to many types of generation islanded from the central grid -- as climate pressures on the U.S. grid mount and more developers eye installations on the recovering island.

“There’s not a standard definition of what a microgrid is, not even on the mainland,” said Román Morales.

According to the commission's regulation, “a microgrid shall consist, at a minimum, of generation assets, loads and distribution infrastructure. Microgrids shall include sufficient generation, storage assets and advanced distribution technologies, including advanced inverters, to serve load under normal operating and usage conditions.”

All microgrids must be renewable (with at least 75 percent of power from clean energy), combined heat and power (CHP) or hybrid CHP-and-renewable systems. The regulation applies to microgrids controlled and owned by individuals, customer cooperatives, nonprofit and for-profit companies, and cities, but not those owned by the Puerto Rico Electric Power Authority (PREPA). Owners must submit a registration application for approval, including a certification of inspection from a licensed electric engineer, and an annual fuel, generation and sales report that details generation and fuel source, as well as any change in the number of customers served.

Microgrids, like the SDG&E microgrid in Ramona in California, can interconnect with the PREPA system, but if a microgrid will use PREPA infrastructure, owners will incur a monthly fee. That amounts to $25 per customer up to a cap of $250 per month for small cooperative microgrids. The cost for larger systems is calculated using a separate, more complex equation. Operators can also sell excess energy back to PREPA.

 

Big goals for the island's future grid

In total, 53 groups and companies, including Sunnova, AES, the Puerto Rico Solar Energy Industries Association (PR-SEIA), the Advanced Energy Management Alliance (AEMA), and the New York Smart Grid Consortium, submitted their thoughts about microgrids or, in many cases, broader goals for the island’s future energy system. It was a quick turnaround: The Puerto Rico Energy Commission offered a window of just 10 days to submit advice, although the commission continued to accept comments after the deadline.

“PREC wanted the input as fast as possible because of the urgency,” said AES CEO Chris Shelton.

AES’ plan includes a network of “mini-grids” that could range in size from several megawatts to one large enough to service the entire city of San Juan.

“The idea is, you connect those to each other with transmission so they can have a co-optimized portfolio effect and lower the overall cost,” said Shelton. “But they would be largely autonomous in a situation where the tie-lines between them were broken.”

According to estimates provided in AES’ filing, utility-scale solar installations over 50 megawatts on the island could cost between $40 and $50 per megawatt-hour. Those prices make solar located near load centers an economic alternative to the island’s fossil-fuel generating plants. The utility’s analysis showed that a 10,000-megawatt solar system could replace 12,000 gigawatt-hours of fossil generation, with 25 gigawatt-hours of battery storage leveling out load throughout the day. Puerto Rico’s peak load is 3,000 megawatts.

In other filings, PR-SEIA urged a restructuring of FEMA funds so they’re available for microgrid development. GridWise Alliance wrote that plans should consider cybersecurity, and AEMA recommended the commission develop an integrated resource plan (IRP) that includes distributed energy resources, microgrids and non-wires alternatives.

 

An air of optimism, though 1.5 million are still without power

After the commission completes the microgrid rulemaking, a new IRP is next on the commission’s to-do list. PREPA must file that plan in July, and regulators are working furiously to make sure it incorporates the recent flood of rebuilding recommendations from the energy industry.

Though the commission has the final say when it comes to approval of the plan, PREPA will lead the IRP process. The utility’s newly formed Transformation Advisory Council (TAC), a group of 11 energy experts, will contribute.

With that group, along with New York’s Resiliency Working Group, lessons from California's grid transition, the Energy Commission, the utility itself, and the dozens of other clean energy experts and entrepreneurs who want to offer their two cents, the energy planning process has a lot of moving parts. But according to Julia Hamm, CEO of the Smart Electric Power Alliance and a member of both the Energy Resiliency Working Group and the TAC, those working to establish standards for Puerto Rico’s future are hitting their stride.

“Certainly over the past three months, it has been a bit of a challenge to ensure that everybody has been coordinating efforts. Just over the past couple of weeks, we’ve seen some good progress on that front. We’re starting to see a lot more communication,” she said, adding that an air of optimism has settled on the process. “The key stakeholders all have a very common vision for Puerto Rico when it comes to the power sector.”

Nisha Desai, a PREPA board member who is liaising with the TAC, affirmed that collaborators are on the same page. “Everyone is violently in agreement that the future of Puerto Rico involves renewables, microgrids and distributed generation,” she said.

The TAC will hold its first in-person meeting in mid-January, and has already consulted with the utility on its formal fiscal plan submission, due January 10.

Though many taking part in the process feel the once-harried recovery is beginning to adopt a more organized approach, Desai acknowledges that “there are a lot of people in Puerto Rico who feel forgotten.”

Puerto Rico’s current generation sits at just 72.6 percent, in a nation facing longer, more frequent outages due to extreme weather. The government recently offered its first estimate that about half the island, 1.5 million residents, remains without power.

In late December and into January, 1,500 more crewmembers from 18 utilities in states as far flung as Minnesota, Missouri and Arizona will land on the island to aid further restoration through mutual aid agreements.

“The system is getting up to speed, getting to 100 percent, but there’s still some instability,” said Román Morales. “Right now it’s a matter of time.”

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.
