California should have adequate power supplies this summer, even if the state experiences warmer-than-normal temperatures, the California Energy Commission said in a summer outlook.

In the forecast, the Commission said ample resources should be available to meet peak loads and operating reserves will be sufficient even with a very warm summer.

The Commission, however, urged consumers to continue conserving electricity on hot afternoons, noting air conditioners use about 30 percent of total consumption during peak summer hours.

The outlook showed reserve margins, or the level of electricity supplies above demand, are about 22 percent for average weather conditions and 14 percent under hotter-than-normal weather.

California however is divided into regions north and south of Path 26, a transmission line area that frequently has constraints during periods of high electricity demand. Under hotter-than-normal temperatures, the Commission said supplies could be tight in Southern California with reserve margins dipping below the 15 percent to 17 percent target.

Louisiana power grid needs 'complete rebuild' after Hurricane Laura, restoration to take weeks

Louisiana Grid Rebuild After Hurricane Laura will overhaul transmission lines and distribution networks in Lake Charles, as Entergy restores power after catastrophic outages, replacing poles, transformers, and spans to stabilize critical electric infrastructure.

 

Key Points

Entergy's project replacing transmission and distribution in Lake Charles to restore power after the Cat 4 storm

✅ 1,000+ transmission structures and 6,637 poles damaged

✅ Entergy targets first energized line into Lake Charles in 2 weeks

✅ Full rebuild of Calcasieu and Cameron lines will take weeks

 

The main power utility for southwest Louisiana will need to "rebuild" the region's grid after Hurricane Laura blasted the region with 150 mph winds last week, top officials said.

The Category 4 hurricane made landfall last Thursday just south of Lake Charles near Cameron, damaging or destroying thousands of electric poles as well as leaving "catastrophic damages" to the transmission system for southwest Louisiana, similar to impacts seen during Typhoon Mangkhut outages in Hong Kong that left many without electricity.

“This is not a restoration," Entergy Louisiana president and CEO Phillip May said in a statement. "It’s almost a complete rebuild of our transmission and distribution system that serves Calcasieu and Cameron parishes.”

According to Entergy, all nine transmission lines that deliver power into the Lake Charles area are currently out service due to storm damage to multiple structures and spans of wire.

The transmission system is a critical component in the delivery of power to customers’ homes, and failures at substations can trigger large outages, as seen in Los Angeles station fire outage reported recently, according to the company.

Of those structures impacted, many were damaged "beyond repair" and require complete replacement.

Entergy said the damage in southwest Louisiana includes 1,000 transmission structures, 6,637 broken poles, 2,926 transformers and 338 miles of downed distribution wire, highlighting why proactive reliability investments in Hamilton are being pursued by other utilities.

Some 8,300 workers are now in the area working to rebuild the transmission lines, but Entergy said that it will be about two to three weeks before power is available to customers in the Lake Charles area, a timeline similar to Tennessee outages after severe storms reported recently in other states.

"Restoring power will take longer to customers in inaccessible areas of the region," the company said. "While not impacting the expected restoration of service to residential customers, initial estimates are it will take weeks to rebuild all transmission lines in Calcasieu and Cameron parishes."

Entergy Louisiana expects to energize the first of its transmission lines into Lake Charles in two weeks.

“We understand going without power for this extended period will be challenging, and this is not the news customers want to hear. But we have thousands of workers dedicated to rebuilding our grid as quickly as they safely can to return some normalcy to our customers’ lives,” May said.

According to power outage tracking website poweroutage.us, over 164,000 customers remain without service in Louisiana as of Thursday morning, while a Carolinas outage update shows hundreds of thousands affected there as well.

On Wednesday, the Edison Electric Institute, the association of investor-owned electric companies in the U.S., said in a statement to FOX Business that electricity has been restored to approximately 737,000 customers, or 75% of those impacted by the storm across Louisiana, eastern Texas, Mississippi, and Arkansas, even as utilities adapt to climate change to improve resilience.

At least 29,000 workers from 29 states, the District of Columbia and Canada are working to restore power in the region, according to the Electricity Subsector Coordinating Council (ESCC), which is coordinating efforts from government and power industry.

“The transmission loss in Louisiana is significant, with more than 1,000 transmission structures damaged or destroyed by the storm," Department of Energy (DOE) Deputy Secretary Mark Menezes said in a statement. Rebuilding the transmission system is essential to the overall restoration effort and will take weeks given the massive scale and complexity of the work. We will continue to coordinate closely to ensure the full capabilities of the industry and government are marshaled to rebuild this critical infrastructure as quickly as possible.” 

At least 17 deaths in Louisiana have been attributed to the storm; more than half of those killed by carbon monoxide poisoning from the unsafe operation of generators, and residents are urged to follow generator safety tips to reduce these risks. Two additional deaths were verified on Wednesday in Beauregard Parish, which health officials said were due to heat-related illness following the storm.

Ontario's electricity 'recovery rate' could lead to higher hydro bills

Ontario Hydro Flat Rate sets a single electricity rate at 12.8 cents per kWh, replacing time-of-use pricing for Ontario ratepayers, affecting hydro bills this summer, alongside COVID-19 Energy Assistance Program support.

 

Key Points

A fixed 12.8 cents per kWh electricity price replacing time-of-use rates across Ontario from June to November.

✅ Single rate applies 24/7, replacing time-of-use pricing

✅ May slightly raise bills versus pre-pandemic usage patterns

✅ COVID-19 aid offers one-time credits for households, small firms

 

A new provincial COVID-19 measure, including a fixed COVID-19 hydro rate designed to give Ontario ratepayers "stability" on their hydro bills this summer, could result in slightly higher hydro costs over the next four months.

Ontario Premier Doug Ford's government announced over the weekend that consumers would be charged a single around-the-clock electricity rate between June and November, before a Nov. 1 rate increase takes effect, replacing the much-derided time-of-use model ratepayers have complained about for years.

Instead of being charged between 10 to 20 cents per kilowatt hour, depending on the time of day electricity is used, including ultra-low TOU rates during off-peak hours, hydro users will be charged a blanket rate of 12.8 cents per kWh.

"The new rate will simply show up on your bill," Premier Doug Ford said at a Monday afternoon news conference.

While the government said the new fixed rate would give customers "greater flexibility" to use their home appliances without having to wait for the cheapest rate -- and has tabled legislation to lower rates as part of its broader plan -- the new policy also effectively erases a pandemic-related hydro discount for millions of consumers.

For example, a pre-pandemic bill of $59.90 with time-of-use rates, will now cost $60.28 with the government's new recovery rate, as fixed pricing ends across the province, before delivery charges, rebates and taxes.

That same bill would have been much cheaper -- $47.57 -- if the government continued applying the lowest tier of time-of-use 24/7 under an off-peak price freeze as it had been doing since March 24.

The government also introduced support for electric bills with two new assistance programs to help customers struggling to pay their bills.

The COVID-19 Energy Assistance Program will provide a one-time payment consumers to help pay off electricity debt incurred during the pandemic -- which will cost the government $9 million.

The government will spend another $8 million to provide similar assistance to small businesses hit hard by the pandemic.

Cyprus can’t delay joining the electricity highway

Cyprus Electricity Interconnectors link the island to the EU grid via EuroAsia and EuroAfrica projects, enabling renewable energy trade, subsea transmission, market liberalization, and stronger energy security and diplomacy across the region.

 

Key Points

Subsea links connecting Cyprus to Greece, Israel and Egypt for EU grid integration, renewable trade and energy security.

✅ Connects EU, Israel, Egypt via EuroAsia and EuroAfrica

✅ Enables renewables integration and market liberalization

✅ Strengthens energy security, investment, and diplomacy

 

Electricity interconnectors bridging Cyprus with the broader geographical region, mirroring projects like the Ireland-France grid link already underway in Europe, are crucial for its diplomacy while improving its game to become a clean energy hub.

In an interview with Phileleftheros daily, Andreas Poullikkas, chairman of the Cyprus Energy Regulatory Authority (CERA), said electricity cables such as the EuroAsia Interconnector and the EuroAfrica Interconnector, could turn the island into an energy hub, creating investment opportunities.

“Cyprus, with proper planning, can make the most of its energy potential, turning Cyprus into an electricity producer-state and hub by establishing electrical interconnections, such as the EuroAsia Interconnector and the EuroAfrica Interconnector,” said Poullikkas.

He said these electricity interconnectors, “will enable the island to become a hub for electricity transmission between the European Union, Israel and Egypt, with developments such as the Israel Electric Corporation settlement highlighting regional dynamics, while increasing our energy security”.

Poullikkas argued it will have beneficial consequences in shaping healthy conditions for liberalising the country’s electricity market and economy, facilitating the production of electricity with Renewable Energy Sources and supporting broader efforts like the UK grid transformation toward net zero.

“Electricity interconnections are an excellent opportunity for greater business flexibility in Cyprus, ushering new investment opportunities, as seen with the Lake Erie Connector investment across North America, either in electricity generation or other sectors. Especially at a time when any investment or financial opportunity is welcomed.”

He said Cyprus’ energy resources are a combination of hydrocarbon deposits and renewable energy sources, such as solar.

This combination offers the country a comparative advantage in the energy sector.

Cyprus can take advantage of the development of alternative supply routes of the EU, as more links such as new UK interconnectors come online.

Poullikkas argued that as energy networks are developing rapidly throughout the bloc, serving the ever-increasing needs for electricity, and aligning with the global energy interconnection vision highlighted in recent assessments, the need to connect Cyprus with its wider geographical area is a matter of urgency.

He argues the development of important energy infrastructure, especially electricity interconnections, is an important catalyst in the implementation of Cyprus goals, while recognising how rule changes like Australia's big battery market shift can affect storage strategies.

“It should also be a national political priority, as this will help strengthen diplomatic relations,” added Poullikkas.

Implementing the electricity interconnectors between Israel, Cyprus and Greece through Crete and Attica (EuroAsia Interconnector) has been delayed by two years.

He said the delay was brought about after Greece decided to separate the Crete-Attica section of the interconnection and treat as a national project.

Poullikkas stressed the Greek authorities are committed to ensuring the connection of Cyprus with the electricity market of the EU.

“All the required permits have been obtained from the competent authorities in Cyprus and upon the completion of the procedures with the preferred manufacturers, construction of the Cyprus-Crete electrical interconnection will begin before the end of this year. Based on current data, the entire interconnection is expected to be implemented in 2023”.

“The EuroAfrica Interconnector is in the pre-works stage, all project implementation studies have already been completed and submitted to the competent authorities, including cost and benefit studies”.

EuroAsia Interconnector is a leading EU project of common interest (PCI), also labelled as an “electricity highway” by the European Commission.

It connects the national grids of Israel, Cyprus and Greece, creating a reliable energy bridge between the continents of Asia and Europe allowing bi-directional transmission of electricity.

The cost of the entire subsea cable system, at 1,208km, the longest in the world and the deepest at 3,000m below sea level, is estimated at €2.5 bln.

Construction costs for the first phase of the Egypt-Cyprus interconnection (EuroAfrica) with a Stage 1 transmission capacity of 1,000MW is estimated at €1bln.

The Cyprus-Greece (Crete) interconnection, as well as the Egypt-Cyprus electricity interconnector, will both be commissioned by December 2023.

A new material made from carbon nanotubes can generate electricity by scavenging energy from its environment

Carbon Nanotube Solvent Electricity enables wire-free electrochemistry as organic solvents like acetonitrile pull electrons, powering alcohol oxidation and packed bed reactors, energy harvesting, and micro- and nanoscale robots via redox-driven current.

 

Key Points

Solvent-driven electron extraction from carbon nanotube particles generates current for electrochemistry.

✅ 0.7 V per particle via solvent-induced electron flow

✅ Packed bed reactors drive alcohol oxidation without wires

✅ Scalable for micro- and nanoscale robots; energy harvesting

 

MIT engineers have discovered a new way of generating electricity, alongside advances in renewable power at night that broaden what's possible, using tiny carbon particles that can create a current simply by interacting with liquid surrounding them.

The liquid, an organic solvent, draws electrons out of the particles, generating a current, unlike devices based on a cheap thermoelectric material that rely on heat, that could be used to drive chemical reactions or to power micro- or nanoscale robots, the researchers say.

"This mechanism is new, and this way of generating energy is completely new," says Michael Strano, the Carbon P. Dubbs Professor of Chemical Engineering at MIT. "This technology is intriguing because all you have to do is flow a solvent through a bed of these particles. This allows you to do electrochemistry, but with no wires."

In a new study describing this phenomenon, the researchers showed that they could use this electric current to drive a reaction known as alcohol oxidation—an organic chemical reaction that is important in the chemical industry.

Strano is the senior author of the paper, which appears today in Nature Communications. The lead authors of the study are MIT graduate student Albert Tianxiang Liu and former MIT researcher Yuichiro Kunai. Other authors include former graduate student Anton Cottrill, postdocs Amir Kaplan and Hyunah Kim, graduate student Ge Zhang, and recent MIT graduates Rafid Mollah and Yannick Eatmon.

Unique properties
The new discovery grew out of Strano's research on carbon nanotubes—hollow tubes made of a lattice of carbon atoms, which have unique electrical properties. In 2010, Strano demonstrated, for the first time, that carbon nanotubes can generate "thermopower waves." When a carbon nanotube is coated with layer of fuel, moving pulses of heat, or thermopower waves, travel along the tube, creating an electrical current that exemplifies turning thermal energy into electricity in nanoscale systems.

That work led Strano and his students to uncover a related feature of carbon nanotubes. They found that when part of a nanotube is coated with a Teflon-like polymer, it creates an asymmetry, distinct from conventional thermoelectric materials approaches, that makes it possible for electrons to flow from the coated to the uncoated part of the tube, generating an electrical current. Those electrons can be drawn out by submerging the particles in a solvent that is hungry for electrons.

To harness this special capability, the researchers created electricity-generating particles by grinding up carbon nanotubes and forming them into a sheet of paper-like material. One side of each sheet was coated with a Teflon-like polymer, and the researchers then cut out small particles, which can be any shape or size. For this study, they made particles that were 250 microns by 250 microns.

When these particles are submerged in an organic solvent such as acetonitrile, the solvent adheres to the uncoated surface of the particles and begins pulling electrons out of them.

"The solvent takes electrons away, and the system tries to equilibrate by moving electrons," Strano says. "There's no sophisticated battery chemistry inside. It's just a particle and you put it into solvent and it starts generating an electric field."

Particle power
The current version of the particles can generate about 0.7 volts of electricity per particle. In this study, the researchers also showed that they can form arrays of hundreds of particles in a small test tube. This "packed bed" reactor, unlike thin-film waste-heat harvesters for electronics, generates enough energy to power a chemical reaction called an alcohol oxidation, in which an alcohol is converted to an aldehyde or a ketone. Usually, this reaction is not performed using electrochemistry because it would require too much external current.

"Because the packed bed reactor is compact, it has more flexibility in terms of applications than a large electrochemical reactor," Zhang says. "The particles can be made very small, and they don't require any external wires in order to drive the electrochemical reaction."

In future work, Strano hopes to use this kind of energy generation to build polymers using only carbon dioxide as a starting material. In a related project, he has already created polymers that can regenerate themselves using carbon dioxide as a building material, in a process powered by solar energy and informed by devices that generate electricity at night as a complement. This work is inspired by carbon fixation, the set of chemical reactions that plants use to build sugars from carbon dioxide, using energy from the sun.

In the longer term, this approach could also be used to power micro- or nanoscale robots. Strano's lab has already begun building robots at that scale, which could one day be used as diagnostic or environmental sensors. The idea of being able to scavenge energy from the environment, including approaches that produce electricity 'out of thin air' in ambient conditions, to power these kinds of robots is appealing, he says.

"It means you don't have to put the energy storage on board," he says. "What we like about this mechanism is that you can take the energy, at least in part, from the environment."

Revenue from Energy Storage for Microgrids to Total More Than $22 Billion in the Next Decade

Energy Storage for Microgrids enables renewables integration via ESS, boosting resilience and reliability while supporting solar PV and wind, innovative financing, and business models, with strong growth forecast across Asia-Pacific and North America.

 

Key Points

Systems that store energy in microgrids to integrate renewables, boost resilience, and optimize distributed power.

✅ Integrates solar PV and wind with stable, dispatchable output

✅ Reduces costs via new financing and service business models

✅ Expands reliable power for remote, grid-constrained regions

 

A new report from Navigant Research examines the global market for energy storage for microgrids (ESMG), providing an analysis of trends and market dynamics in the context of the evolving digital grid landscape, with forecasts for capacity and revenue that extend through 2026.

Interest in energy storage-enabled microgrids is growing alongside an increase in solar PV and wind deployments. Although not required for microgrids to operate, energy storage systems (ESSs) have emerged as an increasingly valuable component of distributed energy networks, including virtual power plants that coordinate distributed assets, because of their ability to effectively integrate renewable generation.

“There are several key drivers resulting in the growth of energy storage-enabled microgrids globally, including the desire to improve the resilience of power supply both for individual customers and the entire grid, the need to expand reliable electricity service to new areas, rising electricity prices, and innovations in business models and financing,” says Alex Eller, research analyst with Navigant Research. “Innovations in business models and financing will likely play a key role in the expansion of the ESMG market during the coming years.”

One example of microgrid deployment for resilience is the SDG&E microgrid in Ramona built to help communities prepare for peak wildfire season.

According to the report, the most successful companies in this industry will be those that can unlock the potential of new business models to reduce the risk and upfront costs to customers. This is particularly true in Asia Pacific and North America, which are projected to be the largest regional markets for new ESMG capacity by far, a trend underscored by California's push for grid-scale batteries to stabilize the grid.

The report, “Market Data: Energy Storage for Microgrids,” outlines the key market drivers and barriers within the global ESMG market. The study provides an analysis of specific trends, including evolving grid edge trends, and market dynamics for each major world region to illustrate how different markets are taking shape. Global ESMG forecasts for capacity and revenue, segmented by region, technology, and market segment, extend through 2026. The report also briefly examines the major technology issues related to ESSs for microgrids.

Google made energy storage news recently when its parent company Alphabet announced it is hoping to revolutionize renewable energy storage using vats of salt and antifreeze. Alphabet’s secretive research lab, simply named “X,” is developing a system for storing renewable energy that would otherwise be wasted. The project, named “Malta,” is hoping its energy storage systems “has the potential to last longer than lithium-ion batteries and compete on price with new hydroelectric plants and other existing clean energy storage methods, according to X executives and researchers,” reports Bloomberg.

Manitoba Hydro scales back rate increase next year

Manitoba Hydro 3.5 Percent Rate Increase proposes a smaller electricity rate hike under Public Utilities Board oversight to bolster financial reserves, address debt and Bipole III costs, amid shifting export sales and water flow conditions.

 

Key Points

It is Manitoba Hydro's proposed 3.5% electricity rate hike for 2019-20 to shore up finances under PUB oversight.

✅ PUB review sought without lengthy hearing

✅ Revenue boost forecast at 59 million dollars

✅ Natural gas rates flat; class shifts adjust bills

 

Manitoba Hydro is scaling back its rate hike request for next year, instead of the annual 7.9 per cent hikes the Crown corporation previously said it would need until 2023-24 to address debt. 

Hydro is asking the Public Utilities Board for a 3.5 per cent rate increase next year, which would take effect on April 1.

In last week's application, Hydro said its new board is reviewing the corporation's financial picture. Once that is complete, the utility expects to submit a new multi-year rate plan in late 2019 that addresses the organization's long-term future.

"It's too speculative at this point to discuss any possible future rate increases," spokesperson Bruce Owen said in an email.

The proposed increase next year is similar to other jurisdictions and nearly in line with the Public Utilities Board's decision to allow an average 3.6 per cent jump in electricity rates in 2018-19, which began this summer.

"The requested 3.5 per cent rate increase … generates a modest level of net income under average water flow conditions that will assist in gradually building the revenue base and reduce the risk of the corporation incurring a loss" in 2019-20, the rate application said.

If approved, consumers would face their second rate increase from Hydro in under a year.

Crown Services Minister Colleen Mayer said she's sympathetic to customers bracing for another rate increase amid NL rate hike concerns that far exceeds the rate of inflation.

"I hear that, very clearly," she said. "The NDP left us with an insurmountable problem — we're trying to fix that."

Hydro goes to court over special rate class for First Nations residents in Manitoba

National Energy Board OK's Manitoba-Minnesota Transmission Project

Next year's rate increase is projected to bring in $59 million of revenue, boosting the Crown corporation's financial reserves by $31 million.

Without it, the utility would deal with a net loss, it said.

This time, Hydro officials are asking PUB to forgo a rate hearing, suggesting neither itself nor the board has the resources for a lengthy six- to nine-month process to review an application where not much has changed financially and would generate a "minimum level of net income," Hydro said in a letter to the board.

The short-term rate relief, the letter recommends, should be "awarded in a timely and cost-effective manner, recognizing that the corporation's long-term financial forecasts will be finalized and available for review" in late 2019.

Hydro's net income next year will be lower than projected, the rate application said, due to a reduction in export sales and increases in depreciation and financing costs from Bipole III.

"Even though they had a total implosion of their previous board, on this very issue, they haven't learned lessons and they continue to be cheerleaders for these rapid rate increases," Kinew said, referring to the exodus of every board member but one earlier this year.

Manitoba Hydro's burgeoning debt surpasses $19 billion

On natural gas, Manitoba Hydro is asking PUB for no rate increase for the next two years.

There will, however, be some changes in rates in different customer classes, Owen said, resulting in modest rate reductions for mainly residential customers and increases for customers who use a lot of natural gas.

The corporation also wants to stop collecting fees to support the furnace replacement program. The initiative will continue with existing fees.
