Arizona Energy Conservation Alert urges APS and TEP customers to curb usage during a heatwave, preventing rolling blackouts, easing peak demand, and supporting grid reliability by raising thermostats, delaying appliances, and pausing pool pumps.

 

Key Points

A utility request during extreme heat to cut demand and protect grid reliability, helping prevent outages.

✅ Raise thermostats to 80 F or higher during peak hours

✅ Delay washers, dryers, dishwashers until after 8 p.m.

✅ Pause pool pumps; switch off nonessential lights and devices

 

After excessive heat forced rolling blackouts for thousands of people across California Friday and Saturday, Arizona Public Service Electric is asking customers to conserve energy this afternoon and evening.

“Given the extended heat wave in the western United States and climate-related grid risks that utilities are monitoring, APS is asking customers to conserve energy due to extreme energy demand that is driving usage higher throughout the region with today’s high temperatures,” APS said in a statement.

Tucson Electric Power has made a similar request of customers in its coverage area.


APS is asking customers to conserve energy in the following ways Tuesday until 8 p.m.:

  • Raise thermostat settings to no lower than 80 degrees.
  • Turn off extra lights and avoid use of discretionary major appliances such as clothes washers, dryers and dishwashers.
  • Avoid operation of pool pumps.

The request from APS also came just hours after Arizona Corporation Commission Chairman Bob Burns sent a letter to electric utilities under the commission's umbrella, like APS, to see if they are in good shape or anticipate any problems given looming shortages in California. He requested the companies respond by noon Friday.


"The whole plan is to take a look at the system early in the Summer," Burns said. "Early May we look at the system, make sure we're ready and able to serve the public throughout the entire heat cycle."

Burns told ABC15 the Summer Preparedness workshop with utilities took place in May and the regulated utilities reported they were well equipped to meet the anticipated peaks of the Summer, even as supply-chain pressures mount across the industry. Tuesday's letter to the electric companies seeks to see if they are still able to "adequately, safely and reliably" serve customers through the heatwave, or if what happened in California could take place here.

"With the activities that are occurring over in California, including tight grid conditions that have repeatedly tested operators, we just want to double check," Burns said.

An APS representative told ABC15 they have adequate supply and reserve and don't anticipate any problems.

However, the rolling blackouts in California also caught the attention of Commissioner Lea Marquez Peterson. She is calling on the chairman to hold an emergency meeting amid wildfire concerns across California and the region.

"The risk to Arizonans and the fact that energy could be interrupted, that we had some kind of rolling blackout like California would have, would be really a public health issue," Peterson said. "It could be life and death in some cases for vulnerable populations."

UK's Energy Transition Stalled by Supply Delays

UK Clean Energy Supply Chain Delays are slowing decarbonization as transformer lead times, grid infrastructure bottlenecks, and battery storage contractors raise costs and risk 2030 targets despite manufacturing expansions by Siemens Energy and GE Vernova.

 

Key Points

Labor and equipment bottlenecks delay transformers and grid upgrades, risking the UK's 2030 clean power target.

✅ Transformer lead times doubled or tripled, raising project costs

✅ Grid infrastructure and battery storage contractors in short supply

✅ Firms expand capacity cautiously amid uncertain demand signals

 

The United Kingdom's ambitious plans to transition to clean energy are encountering significant obstacles due to prolonged delays in obtaining essential equipment such as transformers and other electrical components. These supply chain challenges are impeding the nation's progress toward decarbonizing its power sector by 2030, even as wind leads the power mix in key periods.

Supply Chain Challenges

The global surge in demand for renewable energy infrastructure, including large-scale storage solutions, has led to extended lead times for critical components. For example, Statera Energy's storage plant in Thurrock experienced a 16-month delay for transformers from Siemens Energy. Such delays threaten the UK's goal to decarbonize power supplies by 2030.

Economic Implications

These supply chain constraints have doubled or tripled lead times over the past decade, resulting in increased costs and straining the energy transition as wind became the main source of UK electricity in a recent milestone. Despite efforts to expand manufacturing capacity by companies like GE Vernova, Hitachi Energy, and Siemens Energy, the sector remains cautious about overinvesting without predictable demand, and setbacks at Hinkley Point C have reinforced concerns about delivery risks.

Workforce and Manufacturing Capacity

Additionally, there is a limited number of companies capable of constructing and maintaining battery sites, adding to the challenges. These issues underscore the necessity for new factories and a trained workforce to support the electrification plans and meet the 2030 targets.

Government Initiatives

In response to these challenges, the UK government is exploring various strategies to bolster domestic manufacturing capabilities and streamline supply chains while supporting grid reform efforts underway to improve system resilience. Investments in infrastructure and workforce development are being considered to mitigate the impact of global supply chain disruptions and advance the UK's green industrial revolution for next-generation reactors.

The UK's energy transition is at a critical juncture, with supply chain delays posing substantial risks to achieving decarbonization goals, including the planned end of coal power after 142 years for the UK. Addressing these challenges will require coordinated efforts between the government, industry stakeholders, and international partners to ensure a sustainable and timely shift to clean energy.

India Electricity Prices are Spiking

India spot electricity prices surged on Q3 demand, lifting power tariffs in the spot market as discoms scrambled for supply; Sembcorp SGPL boosted PLF and short-term PPA realizations, benefiting from INR per kWh peaks.

 

Key Points

India spot electricity prices hit Q3 records amid demand spikes, lifting tariffs and aiding Sembcorp SGPL via PLF gains.

✅ Record 10.6 cents/kWh average; 15-minute peak 20.7 cents/kWh

✅ SGPL shifted output to short-term PPA at 7.3 cents/kWh

✅ PLF ramped above 90%, cutting core losses by 30-40%

 

Electricity prices in India, now the third-largest electricity producer globally, bolted to a record high of 10.6 cents/kWh (INR5.1/kWh) in Q3.

A jolt in Indian spot electricity prices could save Sembcorp Industries' Indian business from further losses, even though demand has occasionally slumped in recent years, UOB Kay Hian said.

The firm said spot electricity prices in India bolted to a record high of 10.6 cents/kWh (INR5.1/kWh) in Q3 and even hit a 15-minute peak of 20.7 cents/kWh (9.9/kWh). The spike was due to a power supply crunch on higher electricity demand from power distribution companies, alongside higher imported coal volumes as domestic supplies shrank.

As an effect, Sembcorp Industries' Sembcorp Gayatri Power Limited's (SGPL) losses of $26m in Q1 and $29m in Q2 could narrow down by as much as 30-40%.

On a net basis, SGPL will recognise a significantly higher electricity tariff in 3Q17. By tactically shutting down its Unit #3 for maintenance, Unit #4 effectively had its generation contracted out at the higher short-term PPA tariff of around 7.3 cents/kWh (Rs3.5/kWh).

SGPL also capitalised on the price spike in 3Q17 as it ramped up its plant load factor (PLF) to more than 90%.

“On the back of this, coupled with the effects of reduced finance costs, we expect SGPL’s 3Q17 quarterly core loss to shrink by 30-40% from previous quarters,” UOB Kay Hian said.

Whilst electricity prices have corrected to 7.1 cents/kWh (INR3.4/kWh), the firm said it could still remain elevated on structural factors, even as coal and electricity shortages ease nationwide.

Sembcorp Industries' India operations brought in a robust performance for Q3. PLF for Thermal Powertech Corporation India Limited (TPCIL) hit 91%, whilst it reached 73% for SGPL, echoing the broader trend of thermal PLF up across the sector.

Utility giant Electricite de France acquired 50pc stake in Irish offshore wind farm

Codling Bank Offshore Wind Project will deliver a 1.1 GW offshore wind farm off the Wicklow coast, as EDF Renewables and Fred Olsen Renewables invest billions to support Ireland's CAP 2030 and cut carbon emissions.

 

Key Points

A 1.1 GW offshore wind farm off Co Wicklow, led by EDF and Fred Olsen, advancing Ireland's CAP 2030 targets.

✅ Up to 1.1 GW capacity; hundreds of turbines off Co Wicklow

✅ EDF Renewables partners with Fred Olsen Renewables

✅ Investment well over €2bn, supporting 70% electricity by 2030

 

It’s been previously estimated that the entire Codling Bank project, which will eventually see hundreds of wind turbines, such as a huge offshore wind turbine now coming to market, erected about 13km off the Co Wicklow coast, could be worth as much as €100m. The site is set to generate up to 1.1 gigawatts of electricity when it’s eventually operational.

It’s likely to cost well over €2bn to develop, and with new pipelines abroad where Long Island offshore turbine proposals are advancing, scale economies are increasingly relevant.

The other half of the project is owned by Norway’s Fred Olsen Renewables, with tens of millions of euro already reportedly spent on surveys and other works associated with the scheme. Initial development work started in 2003.

Mr Barrett will now continue to focus on his non-Irish renewable projects, at a time when World Bank wind power support is accelerating in developing countries, said Hazel Shore, the company that sold the stake. It added that Johnny Ronan and Conor Ronan, the developer’s brother, will retain an equity interest in the Codling project.

“The Hazel Shore shareholders remain committed to continuing their renewable and forestry businesses,” noted the firm, whose directors include Paddy Teahon, a former secretary of the Department of the Taoiseach and chairman of the National Offshore Wind Association of Ireland.

The French group’s EDF Renewables subsidiary will now partner with the Norwegian firm to develop and build the Codling Bank project, in a sector widely projected to become a $1 trillion business over the coming decades.

EDF pointed out that the acquisition of the Codling Bank stake comes after the government committed to reducing carbon emissions. A Climate Action Plan launched last year will see renewable projects generating 70pc of Ireland’s electricity by 2030, with more than a third of Irish electricity to be green within four years according to recent analysis. Offshore wind is expected to deliver at least 3.5GW of power in support of the objective.

Bruno Bensasson, EDF Group senior executive vice-president of renewable energies and the CEO of EDF Renewables said the French group is “committed to contributing to the Irish government’s renewables goals”.

“This important project clearly strengthens our strong ambition to be a leading global player in the offshore wind industry,” he added. “This is consistent with the CAP 2030 strategy that aims to double EDF’s renewable energy generation by 2030 and increase it to 50GW net.”

Matthieu Hue, the CEO of EDF Renewables UK and Ireland said the firm already has an office in Dublin and is looking for further renewable projects, as New York's biggest offshore wind farm moves ahead, underscoring momentum.

Last November, the ESB teamed up with EDF in Scotland, reflecting how UK offshore wind is powering up, with the Irish utility buying a 50pc stake in the Neart na Gaoithe offshore wind project. The massive wind farm is expected to generate up to 450MW of electricity and will cost about €2.1bn to develop.

EDF said work on that project is “well under way”.

Experiment Shows We Can Actually Generate Electricity From The Night Sky

Nighttime thermoradiative power converts outgoing infrared radiation into electricity using semiconductor photodiodes, leveraging negative illumination and sky cooling to harvest renewable energy from Earth-to-space heat flow when solar panels rest, regardless of weather.

 

Key Points

Nighttime thermoradiative power converts Earth's outgoing infrared heat into electricity using semiconductor diodes.

✅ Uses negative illumination to tap Earth-to-space heat flow

✅ Infrared semiconductor photodiodes generate small nighttime current

✅ Theoretical output ~4 W/m^2; lab demo reached 64 nW/m^2

 

There's a stark contrast between the freezing temperatures of space and the relatively balmy atmosphere of Earth, and that contrast could help generate electricity, scientists say – and alongside concepts such as space-based solar power, utilizing the same optoelectronic physics used in solar panels. The obvious difference this would have compared with solar energy is that it would work during the night time, a potential source of renewable power that could keep on going round the clock and regardless of weather conditions.

Solar panels are basically large-scale photodiodes - devices made out of a semiconducting material that converts the photons (light particles) coming from the Sun into electricity by exciting electrons in a material such as silicon, while concepts like space solar beaming could complement them during adverse weather.

In this experiment, the photodiodes work 'backwards': as photons in the form of infrared radiation - also known as heat radiation - leave the system, a small amount of energy is produced, similar to how raindrop electricity harvesting taps ambient fluxes in other experiments.

This way, the experimental system takes advantage of what researchers call the "negative illumination effect" – that is, the flow of outgoing radiation as heat escapes from Earth back into space. The setup explained in the new study uses an infrared semiconductor facing into the sky to convert this flow into electrical current.

"The vastness of the Universe is a thermodynamic resource," says one of the researchers, Shanhui Fan from Stanford University in California.

"In terms of optoelectronic physics, there is really this very beautiful symmetry between harvesting incoming radiation and harvesting outgoing radiation."

It's an interesting follow-up to a research project Fan participated in last year: a solar panel that can capture sunlight while also allowing excess heat in the form of infrared radiation to escape into space.

In the new study, this "energy harvesting from the sky" process can produce a measurable amount of electricity, the researchers have shown – though for the time being it's a long way from being efficient enough to contribute to our power grids, but advances in peer-to-peer energy sharing could still make niche deployments valuable.

In the team's experiments they were able to produce 64 nanowatts per square metre (10.8 square feet) of power – only a trickle, but an amazing proof of concept nevertheless. In theory, the right materials and conditions could produce a million times more than that, and analyses of cheap abundant electricity show how rapidly such advances compound, reaching about 4 watts per square metre.

"The amount of power that we can generate with this experiment, at the moment, is far below what the theoretical limit is," says one of the team, Masashi Ono from Stanford.

When you consider today's solar panels are able to generate up to 100-200 watts per square metre, and in China solar is cheaper than grid power across every city, this is obviously a long way behind. Even in its earliest form, though, it could be helpful for keeping low-power devices and machines running at night: not every renewable energy device needs to power up a city.

Now that the researchers have proved this can work, the challenge is to improve the performance of the experimental device. If it continues to show promise, the same idea could be applied to capture energy from waste heat given off by machinery, and results in humidity-powered generation suggest ambient sources are plentiful.

"Such a demonstration of direct power generation of a diode facing the sky has not been previously reported," explain the researchers in their published paper.

"Our results point to a pathway for energy harvesting during the night time directly using the coldness of outer space."

The research has been published in Applied Physics Letters.
