A groundbreaking new study, just released by the Fire Protection Research Foundation, reveals that potentially hazardous electrical conditions can exist and often remain hidden in older homes, and may only be identified during a thorough electrical inspection conducted by a qualified electrician.

The study also shows that the vast majority of potentially hazardous electrical conditions identified are a result of a failure to meet well recognized, proven safety code provisions and failure to properly install or maintain electrical equipment.

The first-of-its-kind study closely examined electrical systems and devices from 30 older homes in 10 states across the United States. The majority of homes in the study ranged in age from 25 years to more than 90 years. Two of the homes were more than 100 years old. This is the first such study to look within and "behind the walls" of older homes and assess the electrical risks and hazards present. Previous studies have shown the frequency of fires in home residential electrical systems has been disproportionately high in homes more than 40 years old.

"Electricity is one of the leading causes of home fires in the United States," said Jack Wells, Chair of the FoundationÂ’s Technical Advisory Committee that has been working on the study. "Every day we put more and more of a burden on the electrical systems in our homes. Because of poor installation or maintenance, some older homes just are not capable of handling that burden. We hope this study will show homeowners the importance of having older homes inspected and, if needed, repaired by qualified electricians."

The Fire Protection Research FoundationÂ’s study examined each homeÂ’s wiring and electrical systems, along with specific devices. After examining the homes, key electrical system elements (receptacles, service entrance panels, lighting fixtures, junction boxes, etc.) were collected and sent to Underwriters Laboratories (UL) where detailed laboratory analyses were conducted. These analyses examined how the elements performed after years of service in the field.

The findings of the study included:

· Some older equipment and wiring appeared well-maintained, performing effectively and safely, but other older homes had dangerous electrical conditions.

· Some older "knob-and-tube" and rubber insulated wiring failed testing that was conducted with high voltage levels, especially after being subject to bending.

· Service panels in most of the homes surveyed had one or more significant safety problems due to aging, improper installation, or misuse.

· Circuit breakers that were not properly installed in boxes for their intended application (e.g. outdoors) showed signs of corrosion, insect infestation, or other potentially serious problems.

· Some of the electrical receptacles examined in the lab failed an important test which measured how hot the receptacle may get under certain conditions.

· Lighting fixtures in several houses showed evidence of potentially dangerous conditions including: improper installation; frayed or damaged wire insulation; improperly grounded boxes; and use of improper wiring and bulbs.

· A large percentage of older homes had improperly installed or maintained wire splices and junction or outlet boxes.

· A small but significant number of ground fault circuit interrupters (GFCI) did not test and function properly. Most of those that did not function had been installed improperly.

· Many of the homes had potentially dangerous electrical conditions that did not comply with the current safety provisions of the National Electrical Code (NEC). In addition, many of the problems identified in this study did not comply with the NEC that was in effect at the time the homes were built or remodeled.

The study reveals that the vast majority of potentially hazardous electrical conditions in these older homes were caused by not only the failure to meet well recognized, proven safety code provisions found in the NEC, but by the failure to properly install and maintain important electrical equipment. In many of the homes, the problems were directly related to the poor quality of electrical system retrofits or changes made after the homes were originally constructed.

"Homeowners can take simple steps to protect their homes and their families from electrical hazards," said Wells. "Have your home inspected by a qualified electrician who is looking specifically at the electrical system. Always use a professional electrician when you have electrical work completed and make certain the work complies with proven safety code provisions."

Based on the study, the Foundation also recommends that communities ensure all electrical work done in homes meets the safety provisions in the current edition of the NEC. That code has been developed over time to provide the highest level of safety through practical, proven safety provisions.

UCP scraps electricity price cap, some will see $7 bill increase this month

Edmonton Electricity Rate Increase signals Alberta RRO changes as the UCP ends the NDP price cap; kilowatt-hour rises to 7.5 cents, raising energy bills for typical households by 3.9 percent in December.

 

Key Points

The end of Alberta’s RRO cap lifts kWh to 7.5 cents, raising an average Edmonton home’s bill about 3.9% in December.

✅ RRO price cap scrapped; kWh set at 7.5 cents in December.

✅ Average 600 kWh home pays about $7.37 more vs November.

✅ UCP ends NDP-era cap after stakeholder and consumer feedback.

 

Electricity will be more expensive for some Edmontonians in December after the UCP government scrapped a program that capped rates amid prices spiking in Alberta this year.

Effective Nov. 30, the province got rid of the consumer price cap program for Regulated Rate Option customers.

In 2017, the NDP government capped the kilowatt per hour price at 6.8 cents under a consumer price cap policy, meaning Edmontonians would pay the market rate and not more than the capped price.

In December, kWh will cost 7.5 cents amid expert warnings to lock in rates across Alberta. Typical Edmonton homes use an average of 600 kWh, increasing bills by $7.37, or 3.9 per cent, compared to November.

In Calgary, electricity bills have been rising as well, reflecting similar market pressures.

The NDP created the capacity system to bring price stability to Albertans, though a Calgary retailer urged scrapping the market overhaul at the time.

Energy Minister Sonya Savage said the UCP decided to scrap it after "overwhelming" feedback from consumers and industry stakeholders, as the province introduced new electricity rules earlier this year.

Website Providing Electricity Purchase Options Offered Fewer Choices For Spanish-speakers

Texas PUC Spanish Power to Choose mandates bilingual parity in deregulated electricity markets, ensuring equal access to plans, transparent pricing, consumer protection, and provider listings for Spanish speakers, mirroring the English site offerings statewide.

 

Key Points

PUC mandate requiring identical Spanish and English plan listings for fair access in the deregulated power market.

✅ Orders parity across English and Spanish plan listings

✅ Increases transparency in a deregulated electricity market

✅ Deadline set for providers to post on both sites

 

The state’s Public Utility Commission has ordered that the Spanish-language version of the Power to Choose website provide the same options available on the English version of the site, a move that comes as shopping for electricity is getting cheaper statewide.

Texas is one of a handful of states with a deregulated electricity market, with ongoing market reforms under consideration to avoid blackouts. The idea is to give consumers the option to pick power plans that they think best fit their needs. Customers can find available plans on the state’s Power To Choose website, or its Spanish-language counterpart, Poder de Escoger. In theory, those two sites should have the exact same offerings, so no one is disadvantaged. But the Texas Public Utility Commission found that wasn’t the case.

Houston Chronicle business reporter Lynn Sixel has been covering this story. She says the Power to Choose website is important for consumers facing the difficult task of choosing an electric provider in a deregulated state, where electricity complaints have recently reached a three-year high for Texans.

“There are about 57 providers listed on the [English] Power to Choose website, and news about retailers like Griddy underscores how varied the offerings can be across providers. [Last week] there were only 23 plans on the Spanish Power to Choose site,” Sixel says. “If you speak Spanish and you’re looking for a low-cost plan, as of last week, it would have been difficult to find some of the really great offers.”

Mustafa Tameez, managing director of Outreach Strategists, a Houston firm that consults with companies and nonprofits on diversity, described this issue as a type of redlining.

“He’s referring to a practice that banks would use to circle areas on maps in which the bank decided they did not want to lend money or would charge higher rates,” Sixel says. “Typically it was poor minority neighborhoods. Those folks would not get the same great deals that their Anglo neighbors would get.”

DeAnn Walker, chairman of the Public Utility Commission, said she was not at all happy about the plans listings in a meeting Friday, against a backdrop where Texas utilities have recently backed out of a plan to create smart home electricity networks.

“She gave a deadline of 8 a.m. Monday morning for any providers who wanted to put their plans on the Power to Choose website, must put them on both the Spanish language and the English language versions,” Sixel says. “All the folks that I talked to really had no idea that there were different plans on both sites and I think that there was sort of an assumption.”

Covid-19 puts brake on Turkey’s solar sector

Turkey Net Metering Suspension freezes regulator reviews, stalling rooftop solar permits and grid interconnections amid COVID-19, pausing licensing workflows, EPC pipelines, and electricity bill credits that drive commercial and household prosumer adoption.

 

Key Points

A pause on technical reviews freezing net metering applications and slowing rooftop solar deployment in Turkey.

✅ Monthly technical committee meetings suspended indefinitely

✅ Rooftop solar permits and grid interconnections on hold

✅ EPC firms urge remote evaluations for transparency

 

The decision by the Turkish Energy Market Regulatory Authority to halt part of the system of processing net metering applications risks bringing the only vibrant segment of the nation’s solar industry to a grinding halt, a risk amplified as global renewables face Covid-19 disruptions across markets.

The regulator has suspended monthly meetings of the committee which makes technical evaluations of net metering applications, citing concerns about the spread of Covid-19, which has already seen U.S. utility-scale solar face delays this year.

The availability of electricity bill credits for net-metering-approved households which inject surplus power into the grid, similar to how British households can sell power back to energy firms, has seen the rooftop projects the scheme is typically associated with remain the only source of new solar generation capacity in Turkey of late.

However the energy regulator’s decision to suspend technical evaluation committee meetings until further notice has seen the largely online licensing process for new solar systems practically cease; by contrast, Berlin is being urged to remove PV barriers to keep projects moving.

The Turkish solar industry has claimed the move is unnecessary, with solar engineering, procurement and construction services businesses pointing out the committee could meet to evaluate projects remotely. It has been argued such a move would streamline the application process and make it more transparent, regardless of the current public health crisis.

 

Net metering 

Turkey introduced net metering for rooftop installations last May and pv magazine has reported the specifics of the scheme, amid debates like New England's grid upgrade costs over who pays.

National grid operator Teias confirmed recently the country added 109 MW of new solar capacity in the first quarter, most of it net-metered rooftop systems, even as Australian distributors warn excess solar can strain local networks.

Net metering has been particularly attractive to commercial electricity users because the owners of small and medium-sized businesses pay more for power, as solar reshapes electricity prices in Northern Europe, than either households or large scale industrial consumers.

Until the recent technical committee decision by the regulator, the chief obstacle to net metering adoption had been the nation’s economic travails. The Turkish lira has lost 14% of its value since January and around 36% over the last two years. The central bank has been using its foreign reserves to support state lenders and the lira but the national currency slipped near an all-time low on Friday and foreign analysts predict the central bank reserves could run dry in July.

The level of exports shipped last month was down 41% on April last year and imports fell 28% by the same comparison, further depressing the willingness of companies to make capital investments such as rooftop solar.

Ontario introduces new fixed COVID-19 hydro rate

Ontario Electricity COVID-19 Recovery Rate sets a fixed price of 12.8 cents/kWh, replacing time-of-use billing and aligning costs across off-peak, mid-peak, and on-peak periods per Ontario Energy Board guidance through Oct. 31.

 

Key Points

A flat 12.8 cents/kWh electricity price in Ontario that temporarily replaces time-of-use rates from June 1 to Oct. 31.

✅ Fixed 12.8 cents/kWh, all hours, June 1 to Oct. 31

✅ Higher than off-peak 10.1, lower than mid/on-peak

✅ Based on Ontario Energy Board average cost

 

Ontario residents will now have to pay a fixed electricity price that is higher than the off-peak hydro rate many in the province have been allowed to pay so far due to the pandemic. 

The announcement, which was made in a news release on Saturday, comes after the Ontario government suspended the normal “time-of-use” billing system on March 24 and as electricity rates are about to change across Ontario. 

The government moved all customers onto the lowest winter rate in response to the pandemic as emergency measures meant more people would be at home during the middle of the day when electricity costs are the highest. 

Now, the government has introduced a new “COVID-19 recovery rate” of 12.8 cents per kilowatt hour at all times of the day. The fixed price will be in place from June 1 to Oct. 31. 

The fixed price is higher than the winter off-peak price, which stood at 10.1 per kilowatt hour. However, it is lower than the mid-peak rate of 14.4 per kilowatt hour and the high-peak rate of 20.8 per kilowatt hour, even though typical bills may rise as fixed pricing ends for many households. 

“Since March 24, 2020, we have invested just over $175 million to deliver emergency rate relief to residential, farm and small business electricity consumers by suspending time-of-use electricity pricing,” Greg Rickford, the minister of energy, northern development and mines, said in a news release. 

“This investment was made to protect the people of Ontario from a marked increase in electricity rates as they did their part by staying home to prevent the further spread of the virus.”

Rickford said that the COVID-19 recovery rate is based on the average cost of electricity set by the Ontario Energy Board. 

“This fixed rate will continue to suspend time-of-use prices in a fiscally responsible manner,” he said. "Consumers will have greater flexibility to use electricity when they need it without paying on-peak and mid-peak prices, and some may benefit from ultra-low electricity rates under new time-of-use options."

China to build 525-MW hydropower station on Yangtze tributary

Baima Hydropower Station advances China renewable energy on the Wujiang River, a Yangtze tributary in Chongqing; a 525 MW cascade project approved by NDRC, delivering 1.76 billion kWh and improving river shipping.

 

Key Points

An NDRC-approved 525 MW project on Chongqing's Wujiang River, producing 1.76 billion kWh and improving navigation.

✅ 10.2 billion yuan investment; final cascade plant on Wujiang in Chongqing

✅ Expected output: 1.76 billion kWh; capacity 525 MW; NDRC approval

✅ Improves river shipping; relocation of 5,000 residents in Wulong

 

China plans to build a 525-MW hydropower station on the Wujiang River, a tributary of the Yangtze River, in Southwest China's Chongqing municipality, aligning with projects like the Lawa hydropower station elsewhere in the Yangtze basin.

The Baima project, the last of a cascade of hydropower stations on the section of the Wujiang River in Chongqing, has gotten the green light from the National Development and Reform Commission, China's state planning agency, even as some independent power projects elsewhere face uncertainty, such as the Siwash Creek project in British Columbia, the Chongqing Municipal Commission of Development and Reform said Monday.

The project, in Baima township of Wulong district, is expected to involve an investment of 10.2 billion yuan ($1.6 billion), as China explores compressed air generation to bolster grid flexibility, it said.

With a power-generating capacity of 525 MW, it is expected to generate 1.76 billion kwh of electricity a year, supporting efforts to reduce coal power production nationwide, and help improve the shipping service along the Wujiang River.

More than 5,000 local residents will be relocated to make room for the project, which forms part of a broader energy mix alongside advances in nuclear energy in China.

New rules give British households right to sell solar power back to energy firms

UK Smart Export Guarantee enables households to sell surplus solar energy to suppliers, with dynamic export tariffs, grid payments, and battery-friendly incentives, boosting local renewable generation, microgeneration uptake, and decarbonisation across Britain.

 

Key Points

UK Smart Export Guarantee pays homes for exporting surplus solar power to the grid via supplier tariffs.

✅ Suppliers must pay households for exported kWh.

✅ Dynamic tariffs incentivize daytime solar generation.

✅ Batteries boost self-consumption and grid flexibility.

 

Britain’s biggest energy companies will have to buy renewable energy from their own customers through community-generated green electricity models under new laws to be introduced this week.

Homeowners who install new rooftop solar panels from 1 January 2020 will be able to lower their bills as many seek to cut soaring bills by selling the energy they do not need to their supplier.

A record was set at noon on a Friday in May 2017, when solar energy supplied around a quarter of the UK’s electricity, and a recent award that adds 10 GW of renewables indicates further growth.

However, solar panel owners are not always at home on sunny days to reap the benefit. The new rules will allow them to make money if they generate electricity for the grid.

Some 800,000 householders with solar panels already benefit from payments under a previous scheme. However, the subsidies were controversially scrapped by the government in April, with similar reduced credits for solar owners seen in other regions, causing the number of new installations to fall by 94% in May from the month before.

Labour accused the government last week of “actively dismantling” the solar industry. The sector will still struggle this summer as the change does not come in for another seven months, so homeowners have no incentive to buy panels this year.

Chris Skidmore, the minister for energy and clean growth, said the government wanted to increase the number of small-scale generators without adding the cost of subsidies to energy bills. “The future of energy is local and the new smart export guarantee will ensure households that choose to become green energy generators will be guaranteed a payment for electricity supplied to the grid,” he said. The government also hopes to encourage homes with solar panels to install batteries to help manage excess solar power on networks.

Greg Jackson, the founder of Octopus Energy, said: “These smart export tariffs are game-changing when it comes to harnessing the power of citizens to tackle climate change”.

A few suppliers, including Octopus, already offer to buy solar power from their customers, often setting terms for how solar owners are paid that reflect market conditions.

“They mean homes and businesses can be paid for producing clean electricity just like traditional generators, replacing old dirty power stations and pumping more renewable energy into the grid. This will help bring down prices for everyone as we use cheaper power generated locally by our neighbours,” Jackson said.

Léonie Greene, a director at the Solar Trade Association, said it was “vital” that even “very small players” were paid a fair price. “We will be watching the market like a hawk to see if competitive offers come forward that properly value the power that smart solar homes can contribute to the decarbonising electricity grid,” she said.
