Alberta Bill 34 stabilizes electricity prices by empowering the Balancing Pool to borrow, smooth wholesale volatility, and extend PPA cost recovery, protecting consumers with rate stability, predictable power bills, and a reliable grid transition.

 

Key Points

Alberta Bill 34 allows Balancing Pool financing to smooth PPA costs and stabilize electricity prices for consumers.

✅ Loan access for Balancing Pool to manage obligations

✅ Spreads PPA costs to 2030 to reduce monthly charges

✅ Smooths wholesale volatility, stabilizing consumer power bills

 

Proposed legislation would further reduce price volatility in the electricity system and support the province’s made-in-Alberta transition to a stable and reliable system under new electricity rules that puts consumers first.

Bill 34, the Electric Utilities Amendment Act, would allow the Balancing Pool to borrow money from the province to manage its funding obligations. This change, in conjunction with Ministerial Orders that allow the Balancing Pool to smooth price volatility over a longer period of time, would support electricity costs remaining low and stable.

Currently, the average electricity consumer receives a Balancing Pool credit of $1.95 on their monthly bill.

Without the changes proposed in Bill 34, including electricity market changes in Alberta, the Balancing Pool would have to remove that credit and apply a charge of $8.40 per month (approximately $100 per year) starting Jan. 1, 2017, with similar charges applied until the end of 2020.

With the changes proposed in Bill 34 and with supporting regulations that give the Balancing Pool until 2030 to meet its net zero obligation, the charge would instead be 67 cents per month for the average consumer. That’s the equivalent of a
0.1 cent/KWh increase in electricity prices, and $7.73 less per month than if the government hadn’t acted. The amount will be reviewed annually and adjusted as necessary based on the wholesale price of electricity, amid Calgary retailer pushback over a broader market overhaul.

The changes – which allow the Balancing Pool to manage the cost of the power companies’ return of PPAs earlier this year – in conjunction with reaching a settlement with one of the PPA buyers and tentative settlements with two others, would protect consumers and provide price stability as the province transitions its electricity system and implements changes to production and payment across the market.

By extending the operations of the Balancing Pool, providing a loan and setting the initial consumer charge under a consumer price cap approach, the province is ensuring that consumers do not see an immediate and disproportionate increase to power bills from the companies returning their power contracts. These changes complement the government’s work with the companies to settle the PPA disputes. The government will continue to work with the Balancing Pool to understand what steps the Balancing Pool could take to further reduce the cost impact on consumers.

Additionally, Robert Bhatia has been appointed to chair the Balancing Pool’s Board of Directors. The appointment is effective November 29, 2016.

Mr. Bhatia brings a wealth of knowledge and experience to the Balancing Pool, particularly in the areas of financial and fiscal management, strategic leadership, policy and legislation, governance, and operations. During his more than 30 years working for the Government of Alberta, Mr. Bhatia worked in government ministries responsible for finance and revenue, most notably in deputy minister roles.

A recent power outage affecting Northeast Washington, D.C., has drawn attention to the vulnerabilities within the city’s energy infrastructure. The outage, caused by equipment failure at a Pepco substation, left thousands of residents in the dark and raised concerns about the reliability of electricity services in the area.

The Outage: What Happened?

On a typically busy weekday morning, Pepco, the local electric utility, reported significant power disruptions that affected several neighborhoods in Northeast D.C. Initial reports indicated that around 3,000 customers were without electricity due to issues at a nearby substation. The outages were widespread, impacting homes, schools, and businesses, and reflecting pandemic energy insecurity seen in many communities, creating a ripple effect of inconvenience and frustration.

Residents experienced not only the loss of power but also disruptions in daily activities. Many were unable to work from home, students faced challenges with remote learning, and businesses had to close or operate under limited conditions. The timing of the outage further exacerbated the situation, as it coincided with a period of increased demand for electricity, making efforts to prevent summer outages even more crucial for residents and businesses.

Community Response

In the wake of the outage, local community members and leaders quickly mobilized to assess the situation. Pepco crews were dispatched to restore power as swiftly as possible, but residents were left grappling with the immediate consequences. Local organizations and community leaders stepped in to provide support, especially as extreme heat can exacerbate electricity struggles for vulnerable households, offering resources such as food and shelter for those most affected.

Social media became a vital tool for residents to share information and updates about the situation. Many took to platforms like Twitter and Facebook to report their experiences and seek assistance. This grassroots communication helped keep the community informed and fostered a sense of solidarity during the disruption.

The Utility's Efforts

Pepco’s response involved not only restoring power but also addressing the underlying issues that led to the outage. The utility company communicated its commitment to investigating the cause of the equipment failure and ensuring that similar incidents would be less likely in the future. As part of this commitment, Pepco outlined plans for infrastructure upgrades, despite supply-chain constraints facing utilities nationwide, aimed at enhancing reliability across its service area.

Moreover, Pepco emphasized the importance of communication during outages. The company has been working to improve its notification systems, ensuring that customers receive timely updates about outages and restoration efforts. Enhanced communication can help mitigate the frustration experienced during such events and keep residents informed about when they can expect power to be restored.

Broader Implications for D.C.'s Energy Infrastructure

This recent outage has sparked a larger conversation about the resilience of Washington, D.C.’s energy infrastructure. As the city continues to grow and evolve, the demand for reliable electricity is more critical than ever. Frequent outages can undermine public confidence in utility providers and highlight the need for ongoing investment in infrastructure amid an aging U.S. grid that complicates renewable deployment and EV adoption across the country.

Experts suggest that to ensure a more reliable energy supply, utilities must embrace modernization efforts, including the integration of smart grid technology and renewable energy sources. These innovations can enhance the ability to manage electricity supply and demand, especially during unprecedented demand in the Eastern U.S. when heatwaves strain systems, reduce outages, and improve response times during emergencies.

The Path Forward

In response to the outage, community advocates are calling for greater transparency from Pepco and other utility companies. They emphasize the importance of holding utilities accountable for maintaining reliable service and communicating effectively with customers, while also promoting customer bill-reduction initiatives that help households manage costs. Public forums and discussions about energy policy can empower residents to voice their concerns and contribute to solutions.

As D.C. looks to the future, it is essential to prioritize investments in energy infrastructure that can withstand the demands of a growing population. Collaborations between local government, utility companies, and community organizations can drive initiatives aimed at enhancing resilience and ensuring that all residents have access to reliable electricity.

The recent power outage in Northeast D.C. serves as a reminder of the challenges facing urban energy infrastructure. While Pepco's efforts to restore power and improve communication are commendable, the incident highlights the need for long-term solutions to enhance reliability. By investing in modern technology and fostering community engagement, D.C. can work towards a more resilient energy future, ensuring that residents can count on their electricity service even in times of crisis.

After rising for 100 years, electricity demand is flat. Utilities are freaking out.

US Electricity Demand Stagnation reflects decoupling from GDP as TVA's IRP revises outlook, with energy efficiency, distributed generation, renewables, and cheap natural gas undercutting coal, reshaping utility business models and accelerating grid modernization.

 

Key Points

US electricity demand stagnation is flat load growth driven by efficiency, DG, and decoupling from GDP.

✅ Flat sales pressure IOU profits and legacy baseload investments.

✅ Efficiency and rooftop solar reduce load growth and capacity needs.

✅ Utilities must pivot to services, DER orchestration, and grid software.

 

The US electricity sector is in a period of unprecedented change and turmoil, with emerging utility trends reshaping strategies across the industry today. Renewable energy prices are falling like crazy. Natural gas production continues its extraordinary surge. Coal, the golden child of the current administration, is headed down the tubes.

In all that bedlam, it’s easy to lose sight of an equally important (if less sexy) trend: Demand for electricity is stagnant.

Thanks to a combination of greater energy efficiency, outsourcing of heavy industry, and customers generating their own power on site, demand for utility power has been flat for 10 years, with COVID-19 electricity demand underscoring recent variability and long-run stagnation, and most forecasts expect it to stay that way. The die was cast around 1998, when GDP growth and electricity demand growth became “decoupled”:


 

This historic shift has wreaked havoc in the utility industry in ways large and small, visible and obscure. Some of that havoc is high-profile and headline-making, as in the recent requests from utilities (and attempts by the Trump administration) to bail out large coal and nuclear plants amid coal and nuclear industry disruptions affecting power markets and reliability.

Some of it, however, is unfolding in more obscure quarters. A great example recently popped up in Tennessee, where one utility is finding its 20-year forecasts rendered archaic almost as soon as they are released.

 

Falling demand has TVA moving up its planning process

Every five years, the Tennessee Valley Authority (TVA) — the federally owned regional planning agency that, among other things, supplies electricity to Tennessee and parts of surrounding states — develops an Integrated Resource Plan (IRP) meant to assess what it requires to meet customer needs for the next 20 years.

The last IRP, completed in 2015, anticipated that there would be no need for major new investment in baseload (coal, nuclear, and hydro) power plants; it foresaw that energy efficiency and distributed (customer-owned) energy generation would hold down demand.

Even so, TVA underestimated. Just three years later, the Times Free Press reports, “TVA now expects to sell 13 percent less power in 2027 than it did two decades earlier — the first sustained reversal in the growth of electricity usage in the 85-year history of TVA.”

TVA will sell less electricity in 10 years than it did 10 years ago. That is bonkers.

This startling shift in prospects has prompted the company to accelerate its schedule. It will now develop its next IRP a year early, in 2019.

Think for a moment about why a big utility like TVA (serving 9 million customers in seven states, with more than $11 billion in revenue) sets out to plan 20 years ahead. It is investing in extremely large and capital-intensive infrastructure like power plants and transmission lines, which cost billions of dollars and last for decades. These are not decisions to make lightly; the utility wants to be sure that they will still be needed, and will still pay off, for many years to come.

Now think for a moment about what it means for the electricity sector to be changing so fast that TVA’s projections are out of date three years after its last IRP, so much so that it needs to plunge back into the multimillion-dollar, year-long process of developing a new plan.

TVA wanted a plan for 20 years; the plan lasted three.

 

The utility business model is headed for a reckoning

TVA, as a government-owned, fully regulated utility, has only the goals of “low cost, informed risk, environmental responsibility, reliability, diversity of power and flexibility to meet changing market conditions,” as its planning manager told the Times Free Press. (Yes, that’s already a lot of goals!)

But investor-owned utilities (IOUs), which administer electricity for well over half of Americans, face another imperative: to make money for investors. They can’t make money selling electricity; monopoly regulations forbid it, raising questions about utility revenue models as marginal energy costs fall. Instead, they make money by earning a rate of return on investments in electrical power plants and infrastructure.

The problem is, with demand stagnant, there’s not much need for new hardware. And a drop in investment means a drop in profit. Unable to continue the steady growth that their investors have always counted on, IOUs are treading water, watching as revenues dry up

Utilities have been frantically adjusting to this new normal. The generation utilities that sell into wholesale electricity markets (also under pressure from falling power prices; thanks to natural gas and renewables, wholesale power prices are down 70 percent from 2007) have reacted by cutting costs and merging. The regulated utilities that administer local distribution grids have responded by increasing investments in those grids, including efforts to improve electricity reliability and resilience at lower cost.

But these are temporary, limited responses, not enough to stay in business in the face of long-term decline in demand. Ultimately, deeper reforms will be necessary.

As I have explained at length, the US utility sector was built around the presumption of perpetual growth. Utilities were envisioned as entities that would build the electricity infrastructure to safely and affordably meet ever-rising demand, which was seen as a fixed, external factor, outside utility control.

But demand is no longer rising. What the US needs now are utilities that can manage and accelerate that decline in demand, increasing efficiency as they shift to cleaner generation. The new electricity paradigm is to match flexible, diverse, low-carbon supply with (increasingly controllable) demand, through sophisticated real-time sensing and software.

That’s simply a different model than current utilities are designed for. To adapt, the utility business model must change. Utilities need newly defined responsibilities and new ways to make money, through services rather than new hardware. That kind of reform will require regulators, politicians, and risky experiments. Very few states — New York, California, Massachusetts, a few others — have consciously set off down that path.

 

Flat or declining demand is going to force the issue

Even if natural gas and renewables weren’t roiling the sector, the end of demand growth would eventually force utility reform.

To be clear: For both economic and environmental reasons, it is good that US power demand has decoupled from GDP growth. As long as we’re getting the energy services we need, we want overall demand to decline. It saves money, reduces pollution, and avoids the need for expensive infrastructure.

But the way we’ve set up utilities, they must fight that trend. Every time they are forced to invest in energy efficiency or make some allowance for distributed generation (and they must always be forced), demand for their product declines, and with it their justification to make new investments.

Only when the utility model fundamentally changes — when utilities begin to see themselves primarily as architects and managers of high-efficiency, low-emissions, multidirectional electricity systems rather than just investors in infrastructure growth — can utilities turn in earnest to the kind planning they need to be doing.

In a climate-aligned world, utilities would view the decoupling of power demand from GDP growth as cause for celebration, a sign of success. They would throw themselves into accelerating the trend.

Instead, utilities find themselves constantly surprised, caught flat-footed again and again by a trend they desperately want to believe is temporary. Unless we can collectively reorient utilities to pursue rather than fear current trends in electricity, they are headed for a grim reckoning.

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.

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

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

 

Key Points

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

✅ Stabilizes regional demand through 2030 under accelerated adoption

✅ Energy efficiency and demand response are primary levers

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

 

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

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

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

 

National trends

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

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

 

Five scenarios for the Southeast

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

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

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

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

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

 

Why it’s vital to plan broadly

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

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

Russian hackers had 'hundreds of victims' as they infiltrated U.S. power grid

Russian cyberattacks on U.S. power grid exposed DHS warnings: Dragonfly/Energetic Bear breached control rooms, ICS networks, and could trigger blackouts via switch manipulation, phishing, and malware, threatening critical infrastructure and utility operations nationwide.

 

Key Points

State-backed breaches of utility ICS and control rooms enabled potential switch manipulation and blackouts.

✅ DHS: Dragonfly/Energetic Bear breached utility networks

✅ Access reached control rooms and ICS for switch control

✅ Ongoing campaign via phishing, malware, lateral movement

 

Russian hackers for a state-sponsored organization invaded hundreds of control rooms of U.S. electric utilities that could have led to blackouts, a new report says.

The group, known as Dragonfly or Energetic Bear, infiltrated networks of U.S. utilities as part of an effort that is likely ongoing, Department of Homeland Security officials told the Wall Street Journal.

Jonathan Home, chief of industrial-control-system analysis for DHS, said the hackers “got to the point where they could have thrown switches” and upset power flows.

Although the agency did not disclose which companies were impacted, the officials at a briefing Monday said that there were “hundreds of victims” including breaches at power plants across the U.S., and that some companies may not be aware that hackers infiltrated their networks yet.

According to experts, Russia has been preparing for such attacks for some time now, prompting a renewed focus on protecting the grid among utilities and policymakers.

“They’ve been intruding into our networks and are positioning themselves for a limited or widespread attack,” said former Deputy Assistant Defense Secretary Michael Carpenter, now senior director at the Penn Biden Center at the University of Pennsylvania, per the Wall Street Journal. “They are waging a covert war on the West.”

Earlier this year, the Trump administration claimed Russia had staged a power grid hacking campaign against the U.S. energy grid and other U.S. infrastructure.

The report comes after President Trump told reporters last week during a joint press conference in Helsinki alongside Russian President Vladimir Putin that he had no reason not to believe the Russian leader's assurances to him that the Kremlin was not to blame for interference in the election.

Trump later admitted that he misspoke when he said he didn’t “see any reason why” Russia would have meddled in the 2016 election, and said he believes the U.S. intelligence community assessment that found that the Russian government did interfere in the electoral process.

A Snapshot of the US Market for Smart Solar Inverters

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.
