Between January 5 and 10, 1998, Québec experienced exceptionally harsh weather conditions as three successive storms left up to 110 mm of ice over the south of the province. Though robust and well-maintained, the Hydro-Québec grid suffered unprecedented damage.

In the days and weeks that followed, thousands of Hydro-Québec workers, with substantial support from colleagues from Québec companies and neighboring electrical utilities, worked relentlessly to restore power in the regions hardest hit.

By late January, most customers again had power. However, the efforts to ensure a secure power supply did not end there.

Major investments have made the Hydro-Québec grid of today much more robust and better able to withstand the impacts of extreme weather events like the ice storm. As a result, Hydro-Québec is now able to restore service to its customers more quickly.

Q: What has been done since 1998 to minimize the effect of similar weather events in the future?

A: Like other regions of the world, Québec is not immune to extreme meteorologic conditions. We cannot control Nature but we can control how we act and minimize the impacts of such events. We have invested on a number of fronts to reinforce our power network and improve its performance under harsh climatic conditions.

Thousands of poles, towers and kilometers of lines fell in 1998, often through a domino effect, sometimes increasing by 80 the time it took to restore service to our customers.

Now, our new construction standards limit the potential for that effect. The mechanical strength of our grid has been increased. For instance, by making every tenth tower along a transmission line a very robust anti-cascading tower, we limit the damage that results from the collapse of a single tower.

On the distribution system, we have strengthened poles and their anchoring. We thus ensure that the poles remain intact despite high wind and ice loading. Only the conductors fall, not the poles. Such measures make it possible to restore service more quickly.

Since 1998, all new lines have been built to these tougher engineering standards.

Hydro-Québec has also changed the configuration of its transmission system to make energy sources more secure and to include redundant sources of supply in case of line failures. These “loops” permit the delivery energy over different paths.

Furthermore, if a satellite substation on the transmission grid is lost, certain distribution lines can provide backup from another substation in order to supply customers.

Q: How does maintenance work help make the grid more robust?

A: A good example is our effort in the area of vegetation control near transmission and distribution lines, a job that plays a huge role in protecting our power system from the impact of weather events like the ice storm.

Many power failures are caused by contact between branches and power lines. The farther vegetation can be kept away, the better the grid will withstand storms.

Q: If the 1998 storm happened now, how would the power system respond?

A: Restoration times would be much shorter. This is because efforts to reinforce the grid, such as creating loops, strengthening facilities and pruning trees, would reduce the number of customers affected and the extent of damage. Repair efforts would thus be more localized and take less time.

The Banker Trying to Fix the UK's Electricity Grid

UK power grid bottleneck is stalling renewable energy, with connection queues, planning delays, and transmission infrastructure gaps raising costs, slowing decarbonization, and deterring investment as government considers reforms led by a new chief adviser.

 

Key Points

Delays and capacity gaps that hinder connecting new generation and demand, raising costs and slowing decarbonization.

✅ Connection queues delay projects for years

✅ Planning and NIMBY barriers stall transmission builds

✅ Investment costs on bills risk political pushback

 

During his three decades at investment bank Morgan Stanley, Franck Petitgas developed a reputation for solving problems that vexed others. Fixing the UK’s creaking power grid could be his most challenging task yet.

Earlier this year, Prime Minister Rishi Sunak appointed Petitgas as his chief business adviser, and the former financier has been pushing to tackle the gridlock that’s left projects waiting endlessly for a connection, an issue he sees as one of the biggest problems for industry.

But there are no easy solutions to tackle the years-long queue to get on the grid or the drawn-out planning process for building clean power generation, with the energy transition stalled by supply delays compounding the problem. And sluggish progress in expanding and improving the electricity network is preventing the construction of new housing developments and offices, as well as slowing the transition to greener power.

That transition has already taken a knock after Sunak last week controversially watered down some of the UK’s climate ambitions, citing in part the cost to consumers. He also acknowledged the issues surrounding the grid and promised the “most transformative plans” in response, drawing on lessons from Europe’s power crisis where applicable. Those are due to be unveiled within weeks. 

Shortly after his appointment, Petitgas offered reassurances to business leaders at a meeting in Downing Street that solutions were being worked on, according to people familiar with the matter. But there’s a lack of confidence across business that enough will be done.

Cost is a big factor in the expansion of the electricity grid, and some argue a state-owned generation model could ease bills over time. Improving the onshore network alone could require investment of between £100 billion and £240 billion ($122-$293 billion) by 2050, according to a government analysis last year. 

With network expansion funded through power bills, that’s a big ask, particularly with Sunak trailing in polls ahead of an election expected next year.

“It’s very difficult for politicians to say more money should be on bills,” said Emma Pinchbeck, chief executive of Energy UK, a trade body. “So you get to a situation where no one wants to pay for the infrastructure investment until it’s really sticky, and that’s where we’ve got to with the grid.”

There are huge competitive and economic implications if the UK falls further behind. With US President Joe Biden spending an estimated $370 billion on climate measures through his Inflation Reduction Act, and China already a world leader in electric vehicles, Britain’s grid inaction is holding it back in the global race to decarbonize, said Jess Ralston, an analyst at the Energy and Climate Intelligence Unit think tank.

“The UK is dithering and delaying, and not making any strategic decisions,” she said. “You can see companies just saying ‘I’m going to the US, or I’m going to China’.” 

In a statement, the government said it’s a “priority to speed up the time taken to connect new power generators and power consumers to the grid.” It added that it’s taking “significant steps to accelerate grid infrastructure,” including support for new Channel interconnectors announced this year.

The government expects demand for electricity to double by 2035 and that will mean more generation that needs to be linked up to the network by cables and pylons. Local grids will also have to expand to accommodate more connection points for electric vehicles and homes, and invest in large-scale energy storage capacity to balance supply.

But so far, the rapid rise in renewable energy investment has not been accompanied by matching spend on the power network, according to BloombergNEF, a pattern seen in Germany’s grid expansion woes as well.

“The pace and scale of what we now have to deliver is significantly different from the last few decades,” said Carl Trowell, president of UK strategic infrastructure at National Grid. “It’s a national endeavor.”

In June, Electricity Networks Commissioner Nick Winser sent the government recommendations for how to accelerate construction of more transmission infrastructure. He said efforts to decarbonize the power sector will be “wasted if we cannot get the power to homes and businesses.”

“We need a seriously stronger sense of urgency,” said Kevin O’Donovan, country manager for Statkraft UK, which is holding off investment in four wind farms and two solar projects due to grid connection delays.

In addition to cost, the other major stumbling block is planning. Politicians in the governing Conservative Party are wary of angering voters with new infrastructure in rural areas that typically vote Tory. Across the country, “Not In My Back Yard” campaigners – NIMBYs — pose a major challenge to projects.

Petitgas, 62, retired from Morgan Stanley last year after nearly 30 years at the bank, where he led its international division from London. The issues over connections and planning have been repeatedly pointed out to Petitgas by investors and trade groups over a series of meetings this year, according to people familiar with the matter, requesting anonymity discussing private talks.

Yet with a general election looming and the issue plagued by political headaches, many are skeptical that Sunak can find the solutions needed.

One business chief said Downing Street considers the issue too tricky and expensive to tackle in the short-term. Others are concerned that while Petitgas has license from Sunak, he doesn’t have influence across the relevant departments to get grids to the top of the agenda.

 

Wind Farms

Multiple parts of the UK’s climate plans are under pressure. Earlier this month, an auction for contracts to build new wind farms received zero bids from developers, even as wind leads the power mix in many regions, marking yet another green setback. 

The UK is already behind on its target of having 50 gigawatts of offshore wind built by 2030, up from 14 GW today. The challenge is accelerating development without railroading local communities.

Within Sunak’s Conservative Party, some lawmakers are pushing back on new infrastructure in their local areas. A group including Environment Secretary Therese Coffey and former Home Secretary Priti Patel is campaigning against building new pylons across a stretch of eastern England.

According to Adam Bell, director of policy at consultancy Stonehaven, backbench pressure means Sunak is unlikely to take major action on the grid in the near term. He doesn’t see the prime minister accepting Winser’s recommendations, least of all accelerating planning decisions.

“Over the last year, Sunak has favored party management over things that will benefit the country,” Bell said.

Trudeau vows to regulate oil and gas emissions, electric car sales

Canada Oil and Gas Emissions Cap sets five-year targets to cut sector emissions toward net-zero by 2050, alongside an EV mandate, carbon pricing signals, and support for carbon capture, clean energy jobs, climate policy.

 

Key Points

A federal policy to regulate and reduce oil and gas emissions via 5-year targets, reaching net-zero by 2050.

✅ Regulated 5-year milestones to cut oil and gas emissions to net-zero by 2050

✅ Interim EV mandate: 50% by 2030; 100% zero-emission sales by 2035

✅ $2B fund for clean energy jobs in oil- and gas-reliant communities

 

Liberal Leader Justin Trudeau vowed to regulate total emissions from Canada’s oil and gas producers as he laid out his first major climate change promises of the campaign Sunday, a plan that was welcomed by several environmental and climate organizations.

Trudeau said that if re-elected, the Liberals will set out regulated five-year targets for emissions from oil and gas production to get them to net-zero emissions by 2050, a goal that, according to an IEA report will require more electricity, but also create a $2 billion fund to create jobs in oil and gas-reliant communities in Alberta, Saskatchewan and Newfoundland and Labrador.

“Let’s be realistic, over a quarter of Canada’s emissions come from our oil and gas sector. We need the leadership of these industries to decarbonize our country,” Trudeau said.

“That’s why we’ll make sure oil and gas emissions don’t increase and instead go down with achievable milestones,” while ensuring local economies can prosper.“

The Liberals are also introducing an interim electric vehicle mandate, which will require half the cars sold in Canada to be zero-emission by 2030, and because cleaning up electricity is critical to meeting climate pledges, the policy pairs with power-sector decarbonization, ahead of the final mandated target of 100 per cent by 2035.

Trudeau spoke in Cambridge, Ont., where protesters once again made an appearance amid a visible police presence. Officers carried one woman off the property when she refused to leave when asked.

Trudeau alluded to the protesters and their actions, which included sounding sirens and chanting expletives, as he defended his government’s record on climate change including progress in the electricity sector nationally, and touted its new plan.

“Sirens in the background may remind us that this is a climate emergency. That’s why we will move faster and be bolder,” he said.

Canada’s largest oilsands producers have already committed to reaching net zero greenhouse gas emissions by 2050, but the policy proposed Sunday “calls the oil companies’ bluff” by making those goals a legislated requirement, said Keith Stewart, senior energy strategist with Greenpeace Canada.

The new timeline for electric vehicles also “sends a clear signal to auto companies to get cracking (and build them here),” he said on Twitter, even as proposals like a fully renewable grid by 2030 are debated today. “We’d like to see this happen faster but the shift away from voluntary targets to requirements is big.”


Merran Smith, executive director of Clean Energy Canada, a climate program at Simon Fraser University, said clean electricity, clean transportation and “phasing out oil and gas with accountable milestones” must be key priorities over the next decade, aligning with Canada’s race to net-zero and the role of renewable energy.

“Today’s announcement, which checks all of these boxes, is not just good ambition_it’s good policy. Policy that will drive down carbon pollution and drive up clean job growth and economic competitiveness. It is policy that will drive Canada forward with cleaner cars, power Canada with clean electricity, and invest in businesses that will last such as battery manufacturing, electric vehicle manufacturing and low carbon steel,” Smith said in an email.

Michael Bernstein, executive director of the climate policy organization Clean Prosperity, said the promises laid out Sunday offer a “strong boost” to the federal government’s previous climate commitments.

He said the organization prefers market incentives such as carbon pricing, that spur innovation over further regulation. But since the largest oilsands companies have already committed to reaching net-zero emissions, he said the newly unveiled policy could provide some support.

“ First, I would encourage the Liberal Party to release independent modelling showing the types of emissions reductions they expect to achieve with their new package of policies. Second, many policies are referred to in general terms so I hope the Liberal Party will provide further details in the coming days,” he said.

“Finally, the document does not specifically mention carbon capture or carbon dioxide removal technologies but both technologies will be critical to achieve some of the pledges in today’s announcement, especially reaching net-zero emissions in the oil a gas sector.”

NDP Leader Jagmeet Singh painted the announcement as the latest in a string of “empty promises” from the Liberals on climate change, saying Canada has the highest increase in greenhouse gas emissions among all G7 countries, and that provinces like B.C. risk missing 2050 targets as well, he argued.

“Climate targets mean nothing when you don’t act on them. We can’t afford more of Justin Trudeau’s empty words on climate change,” he said in a statement.

The Trudeau Liberals submitted new targets to the United Nations in July, promising that Canada will curb emissions by 40 to 45 per cent from 2005 levels by 2030, building on the net-zero by 2050 plan announced earlier, officials say.

TransAlta Poised to Finalize Alberta Data Centre Agreement in 2025 

TransAlta Alberta Data Centre integrates AI, cloud computing, and renewable energy, tackling electricity demand, grid capacity, decarbonization, and energy storage with clean power, cooling efficiency, and PPA-backed supply for hyperscale workloads.

 

Key Points

TransAlta Alberta Data Centre is a planned AI facility powered mostly by renewables to meet high electricity demand.

✅ Targets partner exclusivity mid-year; ops 18-24 months post-contract.

✅ Supplies ~90% power via TransAlta; balance from market.

✅ Anchors $3.5B clean energy growth and storage in Alberta.

 

TransAlta Corp., one of Alberta’s leading power producers, is moving toward finalizing agreements with partners to establish a data centre in the province, aligned with AI data center grid integration efforts nationally, aiming to have definitive contracts signed before the end of the year.

CEO John Kousinioris stated during an analyst conference that the company seeks to secure exclusivity with key partners by mid-year, with detailed design plans and final agreements expected by late 2025. Once the contracts are signed, the data centre is anticipated to be operational within 18 to 24 months, a horizon mirrored by Medicine Hat AI grid upgrades initiatives that aim to modernize local systems.

Data centres, which are critical for high-tech industries such as artificial intelligence, consume large amounts of electricity to run and cool servers, a trend reflected in U.S. utility power challenges reporting, underscoring the scale of energy demand. In this context, TransAlta plans to supply around 90% of its partner's energy needs for the facility, with the remainder coming from the broader electricity market.

Alberta has identified data centres as a strategic priority, aiming to see $100 billion in AI-related data centre construction over the next five years. However, the rapid growth of this sector presents challenges for the region’s energy infrastructure. Electricity demand from data centres has already outpaced the available capacity in Alberta’s power grid, intensifying discussions about a western Canadian electricity grid to improve regional reliability, potentially impacting the province’s decarbonization goals.

To address these challenges, TransAlta has adopted a renewable energy investment strategy. The company announced a $3.5 billion growth plan focused primarily on clean electricity generation and storage, as British Columbia's clean energy shift advances across the region, through 2028. By then, more than two-thirds of TransAlta’s earnings are expected to come from renewable power generation, supporting progress toward a net-zero electricity grid by 2050 nationally.

The collaboration between TransAlta and data centre developers represents an opportunity to balance growing energy demand with sustainability goals. By integrating renewable energy generation into data centre operations and broader macrogrid investments, Alberta could move toward a cleaner and more resilient energy future.

Opinion: The dilemma over electricity rates and innovation

Canadian Electricity Innovation drives a customer-centric, data-driven grid, integrating renewable energy, EVs, storage, and responsive loads to boost reliability, resilience, affordability, and sustainability while aligning regulators, utilities, and policy for decarbonization.

 

Key Points

A plan to modernize the grid, aligning utilities, regulators, and tech to deliver clean, reliable, affordable power.

✅ Smart grid supports EVs, storage, solar, and responsive loads.

✅ Innovation funding and regulatory alignment cut long-term costs.

✅ Resilience rises against extreme weather and outage risks.

 

For more than 100 years, Canadian electricity companies had a very simple mandate: provide reliable, safe power to all. Keep the lights on, as some would say. And they did just that.

Today, however, they are expected to also provide a broad range of energy services through a data-driven, customer-centric system operations platform that can manage, among other things, responsive loads, electric vehicles, storage devices and solar generation. All the while meeting environmental and social sustainability — and delivering on affordability.

Not an easy task, especially amid a looming electrical supply crunch that complicates planning.

That’s why this new mandate requires an ironclad commitment to innovation excellence. Not simply replacing “like with like,” or to make incremental progress, but to fundamentally reimagine our electricity system and how Canadians relate to it.

Our innovators in the electricity sector are stepping up to the plate and coming up with ingenious ideas, thanks to an annual investment of some $20 billion.

#google#

But they are presented with a dilemma.

Although Canada enjoys among the cleanest, most reliable electricity in the world, we have seen a sharp spike in its politicization. Electricity rates have become the rage and a top-of-mind issue for many Canadians, as highlighted by the Ontario hydro debate over rate plans. Ontario’s election reflects that passion.

This heightened attention places greater pressure on provincial governments, who regulate prices, and in jurisdictions like the Alberta electricity market questions about competition further influence those decisions. In turn, they delegate down to the actual regulators where, at their public hearings, the overwhelming and almost exclusive objective becomes: Keeping costs down.

Consequently, innovation pilot applications by Canadian electricity companies are routinely rejected by regulators, all in the name of cost constraints.

Clearly, electricity companies must be frugal and keep rates as low as possible.

No one likes paying more for their electricity. Homeowners don’t like it and neither do businesses.

Ironically, our rates are actually among the lowest in the world. But the mission of our political leaders should not be a race to the basement suite of prices. Nor should cheap gimmicks masquerade as serious policy solutions. Not if we are to be responsible to future generations.

We must therefore avoid, at all costs, building on the cheap.

Without constant innovation, reliability will suffer, especially as we battle more extreme weather events. In addition, we will not meet the future climate and clean energy targets such as the Clean Electricity Regulations for 2050 that all governments have set and continuously talk about. It is therefore incumbent upon our governments to spur a dynamic culture of innovation. And they must sync this with their regulators.

This year’s federal budget failed to build on the 2017 investments. One-time public-sector funding mechanisms are not enough. Investments must be sustained for the long haul.

To help promote and celebrate what happens when innovation is empowered by utilities, the Canadian Electricity Association has launched Canada’s first Centre of Excellence on electricity. The centre showcases cutting-edge development in how electricity is produced, delivered and consumed. Moreover, it highlights the economic, social and environmental benefits for Canadians.

One of the innovations celebrated by the centre was developed by Nova Scotia’s own NS Power. The company has been recognized for its groundbreaking Intelligent Feeder Project that generates power through a combination of a wind farm, a substation, and nearly a dozen Tesla batteries, reflecting broader clean grid and battery trends across Canada.

Political leaders must, of course, respond to the emotions and needs of their electors. But they must also lead.

That’s why ongoing long-term investments must be embedded in the policies of federal, provincial and territorial governments, and their respective regulatory systems. And Canada’s private sector cannot just point the finger to governments. They, too, must deliver, by incorporating meaningful innovation strategies into their corporate cultures and vision.

That’s the straightforward innovation challenge, as it is for the debate over rates.

But it also represents a generational opportunity, because if we get innovation right we will build that better, greener future that Canadians aspire to.

Sergio Marchi is president and CEO of the Canadian Electricity Association. He is a former Member of Parliament, cabinet minister, and Canadian Ambassador to the World Trade Organization and United Nations in Geneva.

Hungary's Quiet Alliance with Russia in Europe's Energy Landscape

Hungary's Russian Energy Dependence underscores EU tensions, as TurkStream gas flows, discounted imports, and pipeline reliance challenge sanctions, energy security, diversification, and decoupling goals amid Ukraine war pressures and bloc unity concerns.

 

Key Points

It is Hungary's reliance on Russian gas and oil via TurkStream, complicating EU sanctions and energy independence.

✅ 85% gas, 60% oil imports from Russia via TurkStream pipelines.

✅ Discounted contracts seldom cut bills; security cited by Budapest.

✅ EU decoupling targets hampered; sanctions leverage and unity erode.

 

Hungary's energy policies have positioned it as a notable outlier within the European Union, particularly in the context of the ongoing geopolitical tensions stemming from Russia's invasion of Ukraine. While the EU has been actively working to reduce its dependence on Russian energy sources through an EU $300 billion plan to dump Russian energy, Hungary has maintained and even strengthened its energy ties with Moscow, raising concerns about EU unity and the effectiveness of sanctions.

Strategic Energy Dependence

Hungary's energy infrastructure is heavily reliant on Russian supplies. Approximately 85% of Hungary's natural gas and more than 60% of its oil imports originate from Russia. This dependence is facilitated through pipelines such as TurkStream, which delivers Russian gas to Hungary via Turkey and the Balkans amid Europe's energy nightmare over price volatility and security. In 2025, Hungary's gas imports through TurkStream are projected to reach 8 billion cubic meters, a significant increase from previous years. These imports are often secured at discounted rates, although such savings may not always be passed on to Hungarian consumers.

Political and Economic Considerations

Prime Minister Viktor Orbán has been a vocal critic of EU sanctions against Russia and has consistently blocked EU initiatives aimed at providing military aid to Ukraine, even as Ukraine leans on power imports to keep the lights on. His government argues that Russia's military capabilities make it an unyielding adversary and that a ceasefire would only solidify its territorial gains. Orbán's stance has led to Hungary's isolation within the EU on matters related to the conflict in Ukraine.

Economically, Hungary's reliance on Russian energy has been justified by the government as a means to maintain low energy prices for consumers and ensure energy security. However, critics argue that this strategy undermines EU efforts to achieve energy independence and reduces the bloc's leverage over Russia amid a global energy war marked by price hikes and instability.

EU's Response and Challenges

The European Union has set ambitious goals to reduce its reliance on Russian energy, aiming to halt imports of Russian natural gas by the end of 2027 and prohibit new contracts starting in 2025 while exploring gas price cap strategies to contain market volatility. However, Hungary's continued imports of Russian energy complicate these efforts. The TurkStream pipeline, in particular, has become a focal point in discussions about the EU's energy strategy, as it enables ongoing Russian gas exports to Europe despite the bloc's broader decoupling initiatives.

Hungary's actions have raised concerns among other EU member states about the effectiveness of the sanctions regime and the potential for other countries to exploit similar loopholes. There are calls for stricter policies, including banning spot gas purchases and enforcing traceability of gas origins, and consideration of emergency measures to limit electricity prices to ensure genuine energy independence and reduce overreliance on external suppliers.

Hungary's steadfast energy relationship with Russia presents a significant challenge to the European Union's collective efforts to reduce dependence on Russian energy sources. While Hungary argues that its energy strategy is in the national interest, it risks undermining EU solidarity and the bloc's broader geopolitical objectives. As the EU continues to navigate its energy transition and response to the ongoing conflict in Ukraine, including energy ceasefire violations reported by both sides, Hungary's position will remain a critical point of contention within the union.

During this Pandemic, Save Money - How To Better Understand Your Electricity Bill

Commercial Electric Tariffs explain utility rate structures, peak demand charges, kWh vs kW pricing, time-of-use periods, voltage, delivery, capacity ratchets, and riders, guiding facility managers in tariff analysis for accurate energy savings.

 

Key Points

Commercial electric tariffs define utility pricing for energy, demand, delivery, time-of-use periods, riders, and ratchet charges.

✅ Separate kWh charges from kW peak demand fees.

✅ Verify time-of-use windows and demand interval length.

✅ Review riders, capacity ratchets, and minimum demand clauses.

 

Especially during these tough economic times, as major changes to electric bills are debated in some states, facility executives who don’t understand how their power is priced have been disappointed when their energy projects failed to produce expected dollar savings. Here’s how not to be one of them.

Your electric rate is spelled out in a document called a “tariff” that can be downloaded from your utility’s web page. A tariff should clearly spell out the costs for each component that is part of your rate, reflecting cost allocation practices in your region. Don’t be surprised to learn that it contains a bunch of them. Unlike residential electric rates, commercial electric bills are not based solely on the quantity of kilowatt-hours (kWh) consumed in a billing period (in the United States, that’s a month). Instead, different rates may apply to how your power is supplied, how it is delivered via electricity delivery charges, when it was consumed, its voltage, how fast it was used (in kW), and other factors.

If a tariff’s lingo and word structure are too opaque, spend some time with a utility account rep to translate it. Many state utility commissions also have customer advocates that may assist as they explore new utility rate designs that affect customers. Alternatively, for a fee, facility managers can privately chat with an energy consultant.

Common mistakes

Many facility managers try to estimate savings based on an averaged electric rate, i.e., annual electric spend divided by annual kWh. However, in markets where electricity demand is flat, such a number may obscure the fastest rising cost component: monthly peak demand charges, measured in dollars per kW (or kilo-volt-amperes, kVA).

This charge is like a monthly speeding ticket, based solely on the highest speed you drove during that time. In some areas, peak demand charges now account for 30 to 60 percent of a facility’s annual electric spend. When projecting energy cost savings, failing to separately account for kW peak demand and kWh consumption may result in erroneous results, and a lot of questions from the C-suite.

How peak demand charges are calculated varies among utilities. Some base it on the highest average speed of use across one hour in a month, while others may use the highest average speed during a 15- or 30-minute period. Others may average several of the highest speeds within a defined time period (for example, 8 a.m. to 6 p.m. on weekdays). It is whatever your tariff says it is.

Because some power-consuming (or producing) devices, including those tied to smart home electricity networks, vary in their operation or abilities, they may save money on a few — but not all — of those rate components. If an equipment vendor calculates savings from its product by using an average electric rate, take pause. Tell the vendor to return after the proposal has been redone using tariff-based numbers.

When a vendor is the only person calculating potential savings from using a product, there’s also a built-in conflict of interest: The person profiting from an equipment sale should not also be the one calculating its expected financial return. Before signing any energy project contracts, it’s essential that someone independent of the deal reviews projected savings. That person (typically an energy or engineering consultant) should be quite familiar with your facility’s electric tariff, including any special provisions, riders, discounts, etc., that may pertain. When this doesn’t happen, savings often don’t occur as planned. 

For example, some utilities add another form of demand charge, based on the highest kW in a year. It has various names: capacity, contract demand, or the generic term “ratchet charge.” Some utilities also have a minimum ratchet charge which may be based on a percent of a facility’s annual kW peak. It ensures collection of sufficient utility revenue to cover the cost of installed transmission and distribution even when a customer significantly cuts its peak demand.
