On October 31 the first virtual power plant operated by Siemens Energy and RWE Energy came on line.

In a first phase nine hydroelectric facilities operated by Lister- und Lennekraftwerke in Sauerland, North Rhine-Westphalia, were integrated in the plant linkup. The capacity of these distributed generating facilities ranges from 150 kW to 1100 kW. The total capacity of all the plants amounts to approximately 8600 kW.

With the virtual power plant sales channels can be utilized which would otherwise not have been available to the operators of the individual facilities. In the linkup the plants can be operated even more efficiently and thus more economically than before – thus providing benefits for the operators of the distributed generating facilities. RWE will also be marketing the electricity generated on the EEX power exchange.

In the virtual power plant distributed energy management and communication with the generating facilities play a special role. By deploying existing products from Siemens Energy's portfolio such as the distributed energy management system DEMS and the DER (distributed energy resources) controller it was possible to realize the virtual power plant in a very short time: The DEMS is the central feature of the virtual power plant.

With this system it is not only possible to implement an intelligent linkup of the distributed generating facilities but also to achieve cost-effective, eco-friendly unit commitment. The DER controller used for communication is specially geared to meet the requirements of distributed generating facilities.

With this pilot project Siemens and RWE Energy will demonstrate the technical and economic viability of virtual power plants and accumulate findings for further possible applications. In the course of the project further distributed generating facilities such as engine-based cogeneration plants, biomass and wind power plants are to be integrated into the linkup.

In addition to economic benefits the aim of the coordinated utilization of distributed generating facilities is above all to make a contribution toward the improved market integration of these facilities.

Effort to make Philippines among best power grids in Asia

NGCP-SGCC Partnership drives transmission grid modernization in the Philippines, boosting high-voltage capacity, reliability, and resilience, while developing engineering talent via the Trailblazers Program to meet Southeast Asia best practices and utility standards.

 

Key Points

A partnership to modernize the Philippines' grid, boost high-voltage capacity, and upskill NGCP engineers.

✅ Modernizes transmission assets and grid reliability nationwide

✅ Trailblazers Program develops NGCP's engineering leadership

✅ SGCC knowledge transfer on UHV, high-voltage, and best practices

 

The National Grid Corp. of the Philippines (NGCP) is building on its partnership with State Grid Corp of China (SGCC) to expand and modernize transmission facilities, as well as enhance the capabilities of its personnel to advance the country's grid network, aligning with smart grid transformation in Egypt seen in other markets. NGCP Internal Affairs Department head Edwin Natividad said the grid operator is implementing various development programs with SGCC to make the country's power grid among the best power utilities in Asia.

"We have to look at policies aligned with best global practices, including smart grid solutions increasingly adopted worldwide, that we can choose in adopting in the Philippines too," he said. One of NGCP's flagship development program is the Trailblazers Program, the company's strategy to further develop engineers "who will not just be technical experts, but also be the change agents and movers in the NGCP organization as well as in the Philippines' power sector," Natividad said.

"Having the support of the largest utility in the world gives us comfort that this program is designed and implemented by the best in the power industry," he said. Under the program, high performing personnel participating will be prepared for bigger roles later on in their careers at NGCP.

Business ( Article MRec ), pagematch: 1, sectionmatch: 1 "The advantage of such a pool is that it provides flexibility and, eventually, organizational self-sufficiency around the current and future talent needs of NGCP," Natividad said. Now on its third edition, the Trailblazers Program has already sent 76 personnel since it started in November 2016. Natividad said more than 16 of those who previously attended similar programs have already assumed higher roles in NGCP.

Apart from technical skills development, NGCP's partnership with SGCC also provides technical development to improve on the physical transmission assets. "If you will compare the facilities being handled by SGCC with other countries, in terms of handling high voltage capability, SGCC is way ahead.

The higher the voltage it's going to be more difficult to handle," Natividad said, adding they can handle more power to distribute to power distributors. As an example, SGCC's transmission facilities can handle high voltage to as much as 1,000 kiloVolts (kV), whereas the Philippines only has one high voltage facility, the interconnection between Luzon and Visayas, which can handle 500 kV, echoing proposals for macrogrids in Canada to improve reliability.

Natividad said NGCP was the first and biggest investment of SGCC outside of China before it made investments in other parts of the world, even as cybersecurity concerns in Britain have influenced supplier choices. A consortium among businessmen Henry Sy Jr., Robert Coyuito Jr., and SGCC as technical partner, NGCP holds a 25-year concession contract to operate and maintain the country's transmission grid.

Earlier, Sy, NGCP president and CEO, said the company is targeting to become the best utility firm in Southeast Asia. Since it took over the operations and maintenance of the country's power transmission network in 2009, the grid operator has introduced major physical and technological upgrades to ageing state-owned lines and facilities, while in Great Britain an independent operator model is being advanced to reshape system operations.

Sudbury Hydro crews aim to reconnect service after storm

Sudbury Microburst Power Outage strains hydro crews after straight-line winds; New Sudbury faces downed power lines, tree damage, and hazardous access as restoration efforts, mutual aid, and safety protocols aim to reconnect customers by weekend.

 

Key Points

A microburst downed lines in New Sudbury, cutting power as crews tackle hazardous access and complex repairs.

✅ Straight-line winds downed poles, trees, and service lines

✅ Crews face backyard access hazards, complex reconnections

✅ Mutual aid linemen, arborists, and crane work speed restoration

 

About 300 Sudbury Hydro customers are still without power Thursday after Monday's powerful microburst storm, part of a series of damaging storms in Ontario seen across the province.

The utility's spokesperson, Wendy Watson, says the power in the affected New Sudbury neighbourhoods should be back on by the weekend, even as Toronto power outages persisted in a recent storm.

The storm, which Environment Canada said was classified as a microburst or straight line wind damage, similar to a severe windstorm in Quebec, downed a number of power lines in the city.

Now crews are struggling with access to the lines, a challenge that BC Hydro's atypical storm response also highlighted, as they work to reconnect service in the area.

"In some cases, you can't get to someone's back yard, or you have to go through the neighbour's yard," Watson said.

"We have one case where [we had] equipment working over a swimming pool. It's dicey, it's really dirty and it's dangerous."

Veteran arborist Jim Allsop told CBC News he hasn't seen damage like this in his 30-plus years in the business.

"I don't know how many we've done up to date, but I have another 35 trees on houses," Allsop said. "We'll be probably another week."

"We've rented a crane to help speed up the process, and increase safety, and we're getting five or six done in our 12-hour days."

Scott Aultman, a lineman with North Bay Hydro, said he has seen a few storms in his career, and isn't usually surprised by extensive damage a storm can cause.

"When you see a trailer on its side, you know, you don't see that every day," Aultman said.

But during the clean up, Aultman said the spirit of camaraderie runs high with crews from different areas, as seen when Canadian crews helped Florida during Hurricane Irma.

"We were pumped. It's part of the trade, everybody gets together," Aultman said. "We had a big storm in 2006 and the Sudbury guys were up helping us, so it's great, it's nice to be able to return the favour and help them out."

Europe's largest shore power plant opens

AIDAsol shore power Rostock-Warnemfcnde delivers cold ironing for cruise ships, up to 20 MVA at berths P7 and P8, cutting port emissions during berthing and advancing AIDA's green cruising strategy across European ports.

 

Key Points

Rostock-Warnemfcnde shore power supplies two cruise ships up to 20 MVA, enabling cold ironing and cutting emissions.

✅ Up to 20 MVA; powers two cruise ships at berths P7 and P8

✅ Enables cold ironing for AIDA fleet to reduce berth emissions

✅ Part of AIDA green cruising with fuel cells and batteries

 

In a ceremony held in Rostock-Warnemünde yesterday during Germany’s 12th National Maritime Conference, the 2,174-passenger cruise ship AIDAsol inaugurated Europe’s largest shore power plants for ships.

The power plant has been established under a joint agreement between AIDA Cruises, a unit of Carnival Corporation & plc (NYSE/LSE: CCL; NYSE: CUK), the state government of Mecklenburg-Western Pomerania, the city of Rostock and the Port of Rostock.

“With our green cruising strategy, we have been investing in a sustainable cruise market for many years,” said AIDA Cruises President Felix Eichhorn. “The shore power plant in Rostock-Warnemünde is another important step — after the facility in Hamburg — on our way to an emission-neutral cruise that we want to achieve with our fleet. I would like to thank the state government of Mecklenburg-Western Pomerania and all partners involved for the good and trusting cooperation. Together, we are sending out an important signal, not just in Germany, but throughout Europe.”

CAN POWER TWO CRUISE SHIPS AT A TIME
The shore power plant, which was completed in summer 2020, is currently the largest in Europe and aligns with port electrification efforts such as the all-electric berth at London Gateway in the UK. With an output of up to 20 megavolt amperes (MVA), two cruise ships can be supplied with electricity at the same time at berths P7 and P8 in Warnemünde.

In regular passenger operation AIDAsol needs up to 4.5 megawatts per hour (MWh) of electricity.

The use of shore power to supply ships with energy is a decisive step in AIDA Cruises’ plans to reduce local emissions to zero during berthing, complementing recent progress with electric ships on the B.C. coast, as a cruise ship typically stays in port around 40% of its operating time.

As early as 2004, when the order for the construction of AIDAdiva was placed, and for all other ships put into service in subsequent years, the company has considered the use of shore power as an option for environmentally friendly ship operation.

Since 2017, AIDA Cruises has been using Europe’s first shore power plant in Hamburg-Altona, where AIDAsol is in regular operation, while operators like BC Ferries add hybrid ferries to expand low-emission service in Canada. Currently, 10 ships in the AIDA fleet can either use shore power where available or are technically prepared for it.

The aim is to convert all ships built from 2000 onwards, supporting future solutions like offshore charging with wind power.

With AIDA Cruises starting a cruise season from Kiel, Germany, on May 22, AIDAsol will also be the first cruise ship to complete the final tests on a newly built shore power plant there, as innovations such as Berlin’s electric flying ferry highlight the broader shift toward electrified waterways. Construction of that plant is the result of a joint initiative by the state government of Schleswig-Holstein, the city and the port of Kiel and AIDA Cruises. AIDAsol is scheduled to arrive in Kiel on the afternoon of May 13.

As part of its green cruising strategy, AIDA Cruises has been investing in a sustainable cruise operation for many years, paralleling urban shifts toward zero-emission bus fleets in Berlin. Other steps on the path to the zero emission ship of the future are already in preparation. This year, AIDAnova will receive the first fuel cell to be used on an ocean-going cruise ship. In 2022, the largest battery storage system to date in cruise shipping will go into operation on board an AIDA ship, similar to advances in battery-electric ferries in the U.S. In addition, the company is already addressing the question of how renewable fuels can be used on board cruise ships in the future.

Solar Plus Battery Storage Cheaper Than Conventional Power in Germany

Germany Solar-Plus-Storage Cost Parity signals grid parity as solar power with battery storage undercuts conventional electricity. Falling LCOE, policy incentives, and economies of scale accelerate the energy transition and decarbonization across Germany's power market.

 

Key Points

The point at which solar power with battery storage is cheaper than conventional grid electricity across Germany.

✅ Lower LCOE from tech advances and economies of scale

✅ EEG incentives and streamlined installs cut total costs

✅ Enhances energy security, reduces fossil fuel dependence

 

Germany, a global leader in renewable energy adoption, with clean energy supplying about half of its electricity in recent years, has reached a significant milestone: the cost of solar power combined with battery storage has now fallen below that of conventional electricity sources. This development marks a transformative shift in the energy landscape, showcasing the increasing affordability and competitiveness of renewable energy technologies and reinforcing Germany’s position as a pioneer in the transition to sustainable energy.

The decline in costs for solar power paired with battery storage represents a breakthrough in Germany’s energy sector, especially amid the recent solar power boost during the energy crisis, where the transition from traditional fossil fuels to cleaner alternatives has been a central focus. Historically, conventional power sources such as coal, natural gas, and nuclear energy have dominated electricity markets due to their established infrastructure and relatively stable pricing. However, the rapid advancements in solar technology and energy storage solutions are altering this dynamic, making renewable energy not only environmentally preferable but also economically advantageous.

Several factors contribute to the cost reduction of solar power with battery storage:

  1. Technological Advancements: The technology behind solar panels and battery storage systems has evolved significantly over recent years. Solar panel efficiency has improved, allowing for greater energy generation from smaller installations. Similarly, cheaper batteries have advanced, with reductions in cost and increases in energy density and lifespan. These improvements mean that solar installations can produce more electricity and store it more effectively, enhancing their economic viability.

  2. Economies of Scale: As demand for solar and battery storage systems has grown, manufacturers have scaled up production, leading to economies of scale. This scaling has driven down the cost of both solar panels and batteries, making them more affordable for consumers. As the market for these technologies expands, prices are expected to continue decreasing, further enhancing their competitiveness.

  3. Government Incentives and Policies: Germany’s commitment to renewable energy has been supported by robust government policies and incentives. The country’s Renewable Energy Sources Act (EEG) and other supportive measures, alongside efforts to remove barriers to PV in Berlin that could accelerate adoption, have provided financial incentives for the adoption of solar power and battery storage. These policies have encouraged investment in renewable technologies and facilitated their integration into the energy market, contributing to the overall reduction in costs.

  4. Falling Installation Costs: The cost of installing solar power systems and battery storage has decreased as the industry has matured. Advances in installation techniques, increased competition among service providers, and streamlined permitting processes have all contributed to lower installation costs. This reduction in upfront expenses has made solar with battery storage more accessible and financially attractive to both residential and commercial consumers.

The economic benefits of solar power with battery storage becoming cheaper than conventional power are substantial. For consumers, this shift translates into lower electricity bills and reduced reliance on fossil fuels. Solar installations with battery storage allow households and businesses to generate their own electricity, store it for use during times of low sunlight, and even sell excess power back to the grid, reflecting how solar is reshaping electricity prices in Northern Europe as markets adapt. This self-sufficiency reduces exposure to fluctuating energy prices and enhances energy security.

For the broader energy market, the decreasing cost of solar power with battery storage challenges the dominance of conventional power sources. As renewable energy becomes more cost-effective, it creates pressure on traditional energy providers to adapt and invest in cleaner technologies, including responses to instances of negative electricity prices during renewable surpluses. This shift can accelerate the transition to a low-carbon energy system and contribute to the reduction of greenhouse gas emissions.

Germany’s achievement also has implications for global energy markets. The country’s success in making solar with battery storage cheaper than conventional power serves as a model for other nations pursuing similar energy transitions. As the cost of renewable technologies continues to decline, other countries can leverage these advancements to enhance their own energy systems, reduce carbon emissions, and achieve energy independence amid over 30% of global electricity now from renewables trends worldwide.

The impact of this development extends beyond economics. It represents a significant step forward in addressing climate change and promoting sustainability. By reducing the cost of renewable energy technologies, Germany is accelerating the shift towards a cleaner and more resilient energy system. This progress aligns with the country’s ambitious climate goals and reinforces its role as a leader in global efforts to combat climate change.

Looking ahead, several challenges remain. The integration of renewable energy into existing energy infrastructure, grid stability, and the management of energy storage are all areas that require continued innovation and investment. However, the decreasing cost of solar power with battery storage provides a strong foundation for addressing these challenges and advancing the transition to a sustainable energy future.

In conclusion, the fact that solar power with battery storage in Germany has become cheaper than conventional power is a groundbreaking development with wide-ranging implications. It underscores the technological advancements, economic benefits, and environmental gains associated with renewable energy technologies. As Germany continues to lead the way in clean energy adoption, this achievement highlights the potential for renewable energy to drive global change and reshape the future of energy.

PG&E restoring power after intentional shut-offs affect 20,500 customers

PG&E power restoration continues across Butte and Yuba counties after PSPS shut-offs from high winds and dry weather, with crews patrolling overhead lines, repairing damage, and reopening community resource centers near Lake Berryessa.

 

Key Points

PG&E power restoration safely re-energizes lines after PSPS, using inspections and repairs to restore service.

✅ Crews patrolled 800 miles of overhead lines for hazards

✅ Repairs followed wind damage; gradual re-energization

✅ Resource centers offered water, outlets, air conditioning

 

Pacific Gas and Electric Co. field crews have begun restoring power to approximately 20,500 customers in Butte and Yuba counties after the utility shut off electricity to reduce wildfire risk because of gusty winds and dry weather conditions.

More than half of the affected customers had electricity again as of 1:47 p.m. Sunday, according to PG&E, and by 4 p.m. all of Yuba County power had been restored.

The utility also cut electricity for about 1,600 customers in parts of Napa, Solano and Yolo counties, primarily in the Lake Berryessa area, in a PSPS event separate from statewide grid conservation alerts that can trigger rolling blackouts. Power to those areas was switched off at 6:15 a.m. Saturday but was restored by the evening.

As the danger subsided Sunday, utility workers, as part of PG&E's local response planning for winter storms, worked throughout Butte and Yuba counties to re-energize power lines. The shut-offs affected areas including eastern Chico, Oroville and fire-ravaged Paradise.

Technicians checked lines for damage or fire hazards, like vegetation that could interfere with live wires, Pasion said, as part of broader pandemic grid preparedness that informed utility protocols.

PG&E “patrolled approximately 800 miles of overhead power lines,” the company said in a statement. “Crews found instances of damage to de-energized equipment caused by the extreme weather event and are making necessary repairs.”

While the shut-offs inconvenienced businesses and homeowners, they also highlighted energy inequality across impacted neighborhoods, and some called 911 with emergencies and confusion.

A half hour into the shut-off Saturday night, Butte County sheriff’s dispatchers received a call from a person requesting a welfare check on an individual whose care required electricity, according to department call logs. Two calls overnight from the Magalia area requested medical assistance because residents had oxygen concerns for medically sensitive spouses.

One woman requested an ambulance because her “husband was running out of oxygen,” according to the logs.

Around 4:11 a.m. Sunday, a resident of Hidden Valley Mobile Home Park in Oroville called about a tree falling into a trailer, causing a power line to fall, but noted that the electricity was off.

In a comparable storm-related outage, Sudbury Hydro crews worked to reconnect service after severe weather in Ontario.

And there were multiple calls asking for information about the shut-off, including one caller around midnight who was “demanding PG&E turn his power back on.”

The calls led the Butte County Sheriff’s Office to tweet a reminder Sunday afternoon that 911 is reserved for emergencies and requests for information about the power shutdown should be done through PG&E.

The utility opened a community resource center at Harrison Stadium in Oroville (Butte County) on Sunday morning to provide restrooms, bottled water, power outlets and air conditioning to residents. About 40 people showed up at the center in the first few hours, officials said.

“It’s a small but steady stream,” Pasion said.

Power was being restored to parts of Oroville as of 11 a.m. Sunday.

PG&E officials said it could take up to 48 hours for power to be restored in some areas.

For perspective, during severe storms in Ontario, Hydro One crews restored power to more than 277,000 customers within days.

Kenya on Course for $5 Billion Nuclear Plant to Power Industry

Kenya Nuclear Power Plant Project advances with environmental impact assessment, selecting Tana River County under a build-operate-transfer model to boost grid capacity, support manufacturing growth, and assess reactor technology for reliable baseload energy.

 

Key Points

A $5B BOT nuclear facility in Tana River to expand Kenya's grid, aiming to start operations in about seven years.

✅ Environmental impact study published for public review by NEMA

✅ Preferred site: Tana River County near coast; grid integration

✅ BOT concession; reactor tech under evaluation for baseload

 

Kenya’s nuclear agency submitted impact studies for a $5 billion power plant, and said it’s on course to build and start operating the facility in about seven years, as markets like China's nuclear program continue steady expansion.

The government plans to expand its nuclear-power capacity fourfold by 2035, mirroring policy steps in India to revive the sector, the Nuclear Power and Energy Agency said in a report on the National Environment Management Authority’s website. The document is set for public scrutiny before the environmental watchdog can approve it, aligning with global green industrial strategies that weigh nuclear in decarbonization, and pave the way for the project to continue.

President Uhuru Kenyatta wants to ramp up installed generation capacity from 2,712 megawatts as of April to boost manufacturing in East Africa’s largest economy, noting milestones such as Barakah Unit 1 reaching 100% power as indicators of nuclear readiness. Kenya expects peak demand to top 22,000 megawatts by 2031, and other jurisdictions, such as Ontario's exploration of new nuclear, are weighing similar large-scale options, partly due to industrial expansion, a component in Kenyatta’s Big Four Agenda. The other three are improving farming, health care and housing.

The nuclear agency is assessing technologies “to identify the ideal reactor for the country,” it said in the report, including next-gen nuclear designs now being evaluated.

A site in Tana River County, near the Kenyan coast was preferred after studies across three regions, according to the report. The plant will be developed with a concessionaire under a build, operate and transfer model, with innovators such as mini-reactor concepts informing vendor options.
