Emerson Process Management, a global business of Emerson, has been awarded a contract from the China Power Investment Corp. (CPI) to digitally automate a new, ultra-supercritical power plant in central China.

Ultra-supercritical plants require less coal per megawatt-hour, leading to lower emissions, higher efficiency, and lower overall fuel costs.

The Pingdingshan Luyang power plant in the Henan Province, jointly owned by CPI and Pingdingshan Coal Co. Ltd., will use Emerson technologies to manage critical processes, increase plant efficiencies, and boost megawatt production to support the region's economic development and population growth. Under the contract, Emerson will provide automation and control technologies for the first two 1,000-megawatt units expected to go into commercial operation in 2010. The plant will ultimately feature six 1,000-megawatt units.

The win is yet another example of Emerson's global leadership in the power generation industry. To date, Emerson's plant automation and control technologies support 600 gigawatts of the world's power generation capacity.

"The Pingdingshan Luyang power plant is critical to central China," said Hongzhan Wang, instrumentation and control director at CPI. "Emerson's industry-leading automation technology is the logical choice for supporting the region's growing need for more power."

This project marks the first time Emerson's technology will directly control a new 1,000-megawatt turbine in China. Additionally, Emerson's system will monitor and control the boiler and all major plant components. Unifying boiler and turbine operations provides improved unit stability, responsiveness, and thermal efficiencies, as well as tighter overall control of plant operations.

Further, this is the first large-scale implementation of Emerson's digital automation technologies in a Chinese power plant that incorporates high-speed communications networks, intelligent field devices, detailed diagnostics, and predictive maintenance. This approach offers a number of operational and economic advantages, including reduced wiring costs, streamlined device configuration, more efficient plant start-up, and long-term operations and maintenance savings.

"Emerson's extensive experience in the supercritical power market makes us ideally suited for this project," added Bob Yeager, president of the Power&Water Solutions division of Emerson Process Management. "We are extremely proud and pleased to be working with the China Power Investment Corp. on an innovative solution that's now serving nearly 65 percent of the approximately forty 1,000-megawatt units that are built or being built in China."

In Europe, A Push For Electricity To Solve The Climate Dilemma

EU Electrification Strategy 2050 outlines shifting transport, buildings, and industry to clean power, accelerating EV adoption, heat pumps, and direct electrification to meet targets, reduce emissions, and replace fossil fuels with renewables and low-carbon grids.

 

Key Points

EU plan to cut emissions 95% by 2050 by electrifying transport, buildings and industry with clean power.

✅ 60% of final energy from electricity by 2050

✅ EVs dominate transport; up to 63% electric share

✅ Heat pumps electrify buildings; industry to 50% direct

 

The European Union has one of the most ambitious carbon emission reduction goals under the global Paris Agreement on climate change – a 95% reduction by 2050.

It seems that everyone has an idea for how to get there. Some are pushing nuclear energy. Others are pushing for a complete phase-out of fossil fuels and a switch to renewables.

Today the European electricity industry came out with their own plan, amid expectations of greater electricity price volatility in Europe in the coming years. A study published today by Eurelectric, the trade body of the European power sector, concludes that the 2050 goal will not be possible without a major shift to electricity in transport, buildings and industry.

The study finds that for the EU to reach its 95% emissions reduction target, electricity needs to cover at least 60 percent of final energy consumption by 2050. This would require a 1.5 percent year-on-year growth of EU electricity use, with evidence that EVs could raise electricity demand significantly in other markets, while at the same time reducing the EU’s overall energy consumption by 1.3 percent per year.

Transport is one of the areas where electrification can deliver the most benefit, because an electric car causes far less carbon emissions than a conventional vehicle, with e-mobility emerging as a key driver of electricity demand even if that electricity is generated in a fossil fuel power plant.

In the most ambitious scenario presented by the study, up to 63 percent of total final energy consumption in transport will be electric by 2050, and some analyses suggest that mass adoption of electric cars could occur much sooner, further accelerating progress.

Building have big potential as well, according to the study, with 45 to 63 percent of buildings energy consumption could be electric in 2050 by converting to electric heat pumps. Industrial processes could technically be electrified with up to 50 percent direct electrification in 2050, according to the study. The relative competitiveness of electricity against other carbon-neutral fuels will be the critical driver for this shift, but grid carbon intensity differs across markets, such as where fossil fuels still supply a notable share of generation.

Can California Manage its Solar Boom?

California Duck Curve highlights midday solar oversupply and steep evening peak demand, stressing grid stability. Solutions include battery storage, demand response, diverse renewables like wind, geothermal, nuclear, and regional integration to reduce curtailment.

 

Key Points

A mismatch between midday solar surplus and evening demand spikes, straining the grid without storage and flexibility.

✅ Midday solar oversupply forces curtailment and wasted clean energy.

✅ Evening ramps require fast, fossil peaker plants to stabilize load.

✅ Batteries, demand response, regional trading flatten the curve.

 

California's remarkable success in adopting solar power, including a near-100% renewable milestone, has created a unique challenge: managing the infamous "duck curve." This distinctive curve illustrates a growing mismatch between solar electricity generation and the state's energy demands, creating potential problems for grid stability and ultimately threatening to slow California's progress in the fight against climate change.


The Shape of the Problem

The duck curve arises from a combination of high solar energy production during midday hours and surging energy demand in the late afternoon and evening when solar power declines. During peak solar hours, the grid often has an overabundance of electricity, and curtailments are increasing as a result, while as the sun sets, demand surges when people return home and businesses ramp up operations. California's energy grid operators must scramble to make up this difference, often relying on fast-acting but less environmentally friendly power sources.


The Consequences of the Duck Curve

The increasing severity of the duck curve has several potential consequences for California:

  • Grid Strain: The rapid ramp-up of power sources to meet evening demand puts significant strain on the electrical grid. This can lead to higher operational costs and potentially increase the risk of blackouts during peak demand times.
  • Curtailed Energy: To avoid overloading the grid, operators may sometimes have to curtail excess solar energy during midday, as rising curtailment reports indicate, essentially wasting clean electricity that could have been used to displace fossil fuel generation.
  • Obstacle to More Solar: The duck curve can make it harder to add new solar capacity, as seen in Alberta's solar expansion challenges, for fear of further destabilizing the grid and increasing the need for fossil fuel-based peaking plants.


Addressing the Challenge

California is actively seeking solutions to mitigate the duck curve, aligning with national decarbonization pathways that emphasize practicality. Potential strategies include:

  • Energy Storage: Deploying large-scale battery storage can help soak up excess solar electricity during the day and release it later when demand peaks, smoothing out the duck curve.
  • Demand Flexibility: Encouraging consumers to shift their energy use to off-peak hours through incentives and smart grid technologies can help reduce late-afternoon surges in demand.
  • Diverse Power Sources: While solar is crucial, a balanced mix of energy sources, including geothermal, wind, and nuclear, can improve grid stability and reduce reliance on rapid-response fossil fuel plants.
  • Regional Cooperation: Integrating California's grid with neighboring states can aid in balancing energy supply and demand across a wider geographical area.


The Ongoing Solar Debate

The duck curve has become a central point of debate about the future of California's energy landscape. While acknowledging the challenge, solar advocates argue for continued expansion, backed by measures like a bill to require solar on new buildings, emphasizing the urgent need to transition away from fossil fuels. Grid operators and some utility companies call for a more cautious approach, emphasizing grid reliability and potential costs if the problem isn't effectively managed.


Balancing California's Needs and its Green Ambitions

Finding the right path forward is essential; it will determine whether California can continue to lead the way in solar energy adoption while ensuring a reliable and affordable electricity supply. Successfully navigating the duck curve will require innovation, collaboration, and a strong commitment to building a sustainable energy system, as wildfire smoke impacts on solar continue to challenge generation predictability.

Customers on the hook for $5.5 billion in deferred BC Hydro operating costs: report

BC Hydro Deferred Regulatory Assets detail $5.5 billion in costs under rate-regulated accounting, to be recovered from ratepayers, highlighting B.C. Utilities Commission oversight, audit scrutiny, financial reporting impacts, and public utility governance.

 

Key Points

BC Hydro defers costs as regulatory assets to recover from ratepayers, influencing rates and financial reporting.

✅ $5.5B in deferred costs recorded as net regulatory assets

✅ Rate impacts tied to B.C. Utilities Commission oversight

✅ Auditor General to assess accounting and governance

 

Auditor General Carol Bellringer says BC Hydro has deferred $5.5 billion in expenses that it plans to recover from ratepayers in the future, as rates to rise by 3.75% over two years.

Bellringer focuses on the deferred expenses in a report on the public utility's use of rate-regulated accounting to control electricity rates for customers.

"As of March 31, 2018, BC Hydro reported a total net regulatory asset of $5.455 billion, which is what ratepayers owe," says the report. "BC Hydro expects to recover this from ratepayers in the future. For BC Hydro, this is an asset. For ratepayers, this is a debt."

She says rate-regulated accounting is used widely across North America, but cautions that Hydro has largely overridden the role of the independent B.C. Utilities Commission to regulate rates.

"We think it's important for the people of B.C. and our members of the legislative assembly to better understand rate-regulated accounting in order to appreciate the impact it has on the bottom line for BC Hydro, for government as a whole, for ratepayers and for taxpayers, especially following a three per cent rate increase in April 2018," Bellringer said in a conference call with reporters.

Last June, the B.C. government launched a two-phase review of BC Hydro to find cost savings and look at the direction of the Crown utility, amid calls for change from advocates.

The review came shortly after a planned government rate freeze was overturned by the utilities commission, which resulted in a three per cent rate increase in April 2018.

A statement by BC Hydro and the government says a key objective of the review due this month is to enhance the regulatory oversight of the commission.

Bellringer's office will become BC Hydro's auditor next year — and will be assessing the impact of regulation on the utility's financial reporting.

"It is a complex area and confidence in the regulatory system is critical to protect the public interest," wrote Bellringer.

Michigan utilities propose more than $20M in EV charging programs

Michigan EV time-of-use charging helps DTE Energy and Consumers Energy manage off-peak demand, expand smart charger rebates, and build DC fast charging infrastructure, lowering grid costs, emissions, and peak load impacts across Michigan's distribution networks.

 

Key Points

Michigan utility programs using time-based EV rates to shift charging off-peak and ease grid load via charger rebates.

✅ Off-peak rates cut peak load and distribution transformer stress.

✅ Rebates support home smart chargers and DC fast charging sites.

✅ DTE Energy and Consumers Energy invest to expand EV infrastructure.

 

The two largest utilities in the state of Michigan, DTE Energy and Consumers Energy, are looking at time-of-use charging rates in two proposed electric vehicle (EV) charging programs, aligned with broader EV charging infrastructure trends among utilities, worth a combined $20.5 million of investments.

DTE Energy last month proposed a $13 million electric vehicle (EV) charging program, which would include transformer upgrades/additions, service drops, labor and contractor costs, materials, hardware and new meters to provide time-of-use charging rates amid evolving charging control dynamics in the market. The Charging Forward program aims to address customer education and outreach, residential smart charger support and charging infrastructure enablement, DTE told regulators in its 1,100-page filing. The utility requested that rebates provided through the program be deferred as a regulatory asset.

Consumers Energy in 2017 withdrew a proposal to install 800 electric vehicle charging ports in its Michigan service territory after questions were raised over how to pay for the $15 million plan. According to Energy News Network, the utility has filed a modified proposal building on the former plan and conversations over the last year that calls for approximately half of the original investment.

Utilities across the country are viewing new demand from EVs as a potential boon to their systems, a shift accelerated by the Model 3's impact on utility planning, potentially allowing greater utilization and lower costs. But that will require the vehicles to be plugged in when other demand is low, to avoid the need for extensive upgrades and more expensive power purchases. Michigan utilities' proposal focuses on off-peak EV charging, as well as on developing new EV infrastructure.

While adoption has remained relatively low nationally, last year the Edison Electric Institute and the Institute for Electric Innovation forecast 7 million EVs on United States' roads by the end of 2025. But unless those EVs can be coordinated, state power grids could face increased stress, the National Renewable Energy Laboratory has said distribution transformers may need to be replaced more frequently and peak load could push system limits — even with just one or two EVs on a neighborhood circuit. 

In its application, DTE told regulators that electrification of transportation offers a range of benefits including "reduced operating costs for EV drivers and affordability benefits for utility customers."

"Most EV charging takes place overnight at home, effectively utilizing distribution and generation capacity in the system during a low load period," the utility said. "Therefore, increased EV adoption puts downward pressure on rates by spreading fixed costs over a greater volume of electric sales."

DTE added that other benefits include reduced carbon emissions, improved air quality, increased expenditures in local economies and reduced dependency on foreign oil for the public at large.

A previous proposal from Consumers Energy included 60 fast charging DC stations along major highways in the Lower Peninsula and 750 240-volt AC stations in metropolitan areas. Consumers' new plan will offer rebates for charger installation, as U.S. charging networks jostle for position amid federal electrification efforts, including residential and DC fast-charging stations.

California Skirts Blackouts With Heat Wave to Test Grid Again

California Heatwave Power Crisis strains CAISO as record demand triggers emergency alerts, demand response, and rolling blackout warnings. PG&E prepares outages while solar fades at peak, drought cuts hydropower, and reliability hinges on conservation.

 

Key Points

Extreme heat driving record demand in California, straining CAISO and prompting conservation to avert rolling blackouts.

✅ CAISO hit a record 52 GW peak load amid triple-digit heat

✅ Emergency alerts spurred demand response, cutting load spikes

✅ Solar drop and drought-weakened hydro worsened evening shortfall

 

California narrowly avoided blackouts for a second successive day even as blistering temperatures pushed electricity demand to a record and stretched the state’s power grid close to its limits.

The state imposed its highest level of energy emergency for several hours late Tuesday and urged consumers to turn off lights, curb air conditioners and shut off power-hungry appliances after a day of extraordinary stress on electricity infrastructure as temperatures in many regions topped 110 degrees Fahrenheit (43 Celsius).

Electricity use had reached 52 gigawatts Tuesday, easily breaking a record that stood since 2006, according to the California Independent System Operator. The state issued emergency alerts direct to cell phones in several counties asking for immediate power conservation, and grid data show that demand plunged in response. Emergency measures were finally lifted at about 9 p.m. local time.

Much of California remains under an excessive heat warning through Friday, with authorities already preparing for more severe pressure on the power system on Wednesday amid a looming supply shortage across the grid. “We aren’t out of the woods yet,” Governor Gavin Newsom said in a message posted on his office’s Twitter account. “We will see continued extreme temps this week and if we rallied today, we can do it again.”

The state’s largest power company, PG&E Corp. said earlier Tuesday that it had notified about 525,000 homes and businesses that they could lose power for up to two hours. That warning came as temperatures in downtown Sacramento hit 116 degrees Fahrenheit, topping a previous 1925 record.

Newsom earlier signed an executive order extending until Friday emergency measures to free up additional power supplies, rather than allowing them to expire as planned on Wednesday. Many state buildings were ordered to power down lights and air conditioning at 4 p.m., and he urged residents and businesses to conserve the equivalent of 3 gigawatts of power in order to stave off blackouts. 

California's Early Brush With Blackouts Bodes Ill For Days Ahead

California faced a similar energy emergency Monday, which was alleviated in part by activating temporary gas-fired power plants operated by the California Department of Water Resources. The current heat wave, which began in the last week of August, is remarkable in both its ferocity and duration, according to officials. 

The prospect of outages underscores how grids have become vulnerable in the face of extreme weather as California transitions from fossil fuels to renewable energy, an approach it is increasingly exporting to Western states as well. California's climate policies have aggressively closed natural-gas power plants in recent years, leaving the state increasingly dependent on solar farms that go dark late in the day just as electricity demand peaks. At the same time, the state is enduring the Southwest’s worst drought in 1,200 years, sapping hydropower production.

The average 15-minute wholesale power price in Caiso surged to $1,806 a megawatt-hour at 4:45 p.m. local time, according to the grid operator’s website.

Average day-ahead prices top $300 a megawatt-hour in Southern California
  
A break from the heat will come across Southern California later this week, thanks to Tropical Storm Kay in the Pacific Ocean, according to weather officials. Kay is forecast to edge up the coastline of Mexico’s Baja California peninsula. As it moves north, the storm will pump moisture and clouds into Southern California and Arizona, taking an edge off the heat.
