Colombian power company Empresas Publicas de Medellin (EPM) plans to build a 200-megawatt (MW) windfarm in Guajira, near the north coast of the country.

Since 2006, EPM has been conducting wind measurements in a 5,000-kilometer area for feasibility studies. EPM plans to complete wind studies by the end of 2010, then select the location of the windfarm and start with equipment specifications and preliminary design.

The bidding process is scheduled to start in 2011. Three types of contracts are being considered, depending on financing. The options at present, from most to least favorable for EPM, are: a turn-key contract; the supply of equipment, with technical assistance, during a year after commissioning; and a build, operate and transfer contract.

Construction kickoff is scheduled for 2012, and the 70 planned wind turbines to be installed would be operational by about 2014, since construction is expected to last 18 months.

The project, which will have a total investment of about $300 million, will include the construction of the 80-kilometer transmission line that needs to be built to connect the windfarm to the grid.

EPM plans to perform the operation and maintenance of the 200-MW facility with its own personnel since they have been performing these activities with Jepirachi Wind Park, which has been generating power to the grid since 2003. Jepirachi was the first windfarm commissioned in Colombia, with a total power output of 19.5 MW.

Texas Utilities back out of deal to create smart home electricity networks

Smart Meter Texas real-time pricing faces rollback as utilities limit on-demand reads, impacting demand response, home area networks, ERCOT wholesale tracking, and thermostat automation, reducing efficiency gains promised through deregulation and smart meter investments.

 

Key Points

A plan linking smart meters to ERCOT prices, enabling near real-time usage alignment and automated demand response.

✅ Twice-hourly reads miss 15-minute ERCOT price spikes.

✅ Less than 1% of 7.3M meters use HAN real-time features.

✅ Limits hinder automation for HVAC, EV charging, and pool pumps.

 

Utilities made a promise several years ago when they built Smart Meter Texas that they’d come up with a way for consumers to monitor their electricity use in real time. But now they’re backing out of the deal with the approval of state regulators, leaving in the lurch retail power companies that are building their business model on the promise of real time pricing and denying consumers another option for managing their electricity costs.

Texas utilities collected higher rates to finance the building of a statewide smart meter network that would allow customers to track their electricity use and the quickly changing prices on wholesale power markets almost as they happened. Some retailers are building electricity plans around this promise, providing customers with in-home devices that would eventually track pricing minute-by-minute and allow them to automatically turn down or shut off air conditioners, pool pumps and energy sucking appliances when prices spiked on hot summer afternoons and turn them back on when they prices fell again.

The idea is to help save consumers money by allowing them to shift their electricity consumption to periods when power is cheaper, typically nights and weekends, even as utility revenue in a free-power era remains a debated topic.

“We’re throwing away a large part of (what) ratepayers paid for,” said John Werner, CEO of GridPlus Texas, one of the companies offering consumers a real-time pricing plan that is scheduled to begin testing next month. “They made the smart meters dumb meters.”

When Smart Meter Texas was launched a decade ago by a consortium of the state’s biggest utilities, it was considered an important part of deregulation. The competitive market for electricity held the promise that consumers would eventually have the technology to control their electricity use through a home area network and cut their power bills.

Regulators and legislators also were enticed by the possibility of making the electric system more efficient and relieving pressure on the power grid as consumers responded to high prices and cut consumption when temperatures soared, with ongoing discussions about Texas grid reliability informing policy choices.

One study found that smart meters coupled with smart real time consumption monitors could reduce electricity use between 3 percent and 5 percent, according to Call Me Power, a website sponsored by the European electricity price shopping service Selectra.

But utilities complained that the home area network devices were expensive to install and not used very often, and, with flat electricity demand weighing on growth, they questioned further investment. CenterPoint manager Esther Floyd Kent filed an affidavit with the commission in May that it costs the utility about $30,000 annually to support the network devices, plus maintenance.

Over a six-year period, CenterPoint paid $124,500, or about $20,000 a year, to maintain the system. As of April, there were only 4,067 network devices in CenterPoint’s service area, meaning the utility pays about $30.70 each year to maintain each device.

Centerpoint last year generated $9.6 billion in revenues and earned a $1.8 billion profit, according to its financial filings. CenterPoint officials did not respond to requests for comment.

Other utilities that are part of the Smart Meter consortium also complained to the Public Utility Commission that, up to now, the system hasn’t developed. All told, Texas has 7.3 million meters connected to Smart Meter Texas, but less than 1 percent are using the networking functions to track real-time prices and consumption, according to the testimony of Donny R. Helm, director of technology strategy and architecture for the state’s largest utility Oncor Electric Delivery Co. in Dallas.

The isssue was resolved recently through a settlement agreement that limits on-demand readings to twice an hour that Smart Meter Texas must provide customers. The price of power changes every 15 minutes, so a twice an hour reading may miss some price spikes.

The Public Utility Commission signed off on the deal, and so did several other groups including several retail electricity providers and the Office of Public Utility Counsel which represents residential customers and small businesses.

Michele Gregg, spokeswoman for the Public Utility Counsel, testified in December that the consumer advocate supported the change because widespread use of the networks never materialized. Catherine Webking, an Austin lawyer who represents the Texas Energy Association for Marketers, a group of retail electric providers, said she believes the deal was a reasonable resolution of providing the benefits of Smart Meter Texas while not incurring too much cost.

But Griddy, an electricity provider that offers customers the opportunity to pay wholesale power prices, which also issued a plea to customers during a price surge, said the state hasn’t given the smart-meter networks a chance and could miss out on its potential. Griddy was counting on the continued adoption of real time pricing as the next step for customers wanting to control their electricity costs.

Right now, Griddy sends out price alerts from the grid operator Electric Reliability Council of Texas so businesses like hotels can run washers and dryers when electricity prices are cheapest. But the company was counting on a smart-meter program that would allow customers to track wholesale prices and manage consumption themselves, making Griddy’s offerings attractive to more people.

Wholesale prices are generally cheaper than retail prices, but they can fluctuate widely, especially when the Texas power grid faces another crisis during extreme weather. Last year, wholesale prices averaged less than 3 cents per kilowatt hour, much lower than than retail rates that now are running above 11 cents, but they can spike at times of high demand to as much as $9 a kilowatt hour.

What customers want is to be able to use energy when it’s cheapest, said Greg Craig, Griddy’s CEO, and they want to do it automatically. They want to be able to program their thermostat so that if the price rises they can shut off their air conditioning and if the price falls, they can charge their electric-powered vehicle.

Griddy customers may still save money even without real time data, he said. But they won’t be able to see their usage in real time or see how much they’re spending.

“The big utilities have big investments in the existing way and going to real time and more transparency isn’t really in their best interest,” said Craig.

Canada Finalizes Clean Electricity Regulations for 2050

Canada Clean Electricity Regulations align climate policy with grid reliability, scaling renewables, energy storage, and low-carbon power to reach net-zero by 2050 while maintaining affordability through federal incentives, provincial flexibility, and investment.

 

Key Points

Nationwide rules to decarbonize power by 2050, capping emissions and protecting grid reliability and affordability.

✅ Net-zero electricity by 2050 with strict emissions limits

✅ Provincial flexibility and federal investments to cut costs

✅ Scales renewables, storage, and clean firm power for reliability

 

Canada's final Clean Electricity Regulations, unveiled in December 2024, alongside complementary provincial frameworks such as Ontario's clean electricity regulations that guide provincial implementation, represent a critical step toward ensuring a sustainable and reliable energy future. With electricity demand set to rise as the country’s population and economy grow, the Canadian government has put forward a robust plan that balances climate goals with the need for reliable, affordable power.

The regulations are designed to reduce greenhouse gas emissions from the electricity sector, which is already one of Canada's cleanest, with 85% of its electricity sourced from renewable energies like hydro, wind, and solar, and growing attention to clean grids and batteries nationwide. The target is to achieve net-zero emissions in electricity generation by 2050, a goal that will support the country’s broader climate ambitions.

One of the central goals of the Clean Electricity Regulations is to make sure that Canada’s power grid can accommodate future demand in light of a critical electrical supply crunch identified by analysts, while ensuring that emissions are cut effectively. The regulations set strict pollution limits but allow flexibility for provinces and territories to meet these goals in ways that suit their local circumstances. This approach recognizes the diverse energy resources across Canada, from the large-scale hydroelectric capacity in Quebec to the growing wind and solar projects in the West.

A key benefit of these regulations is the assurance that they will not result in higher electricity rates for most Canadians. In fact, according to government analyses, and resources like the online CER bill tool that explain how fees and usage affect charges, the regulations are expected to have a neutral or even slightly positive impact on electricity costs. This is due in part to significant federal investments in the electricity sector, totaling over $60 billion. These investments are intended to support the transition to clean electricity while minimizing costs for consumers.

The shift to clean electricity is also expected to generate significant savings for Canadian households. As energy prices continue to fluctuate, clean electricity, especially from renewable sources, is becoming more cost-competitive compared to fossil fuels. Over the next decade, this transition is expected to result in $15 billion in total savings for Canadians, with 84% of households projected to benefit from lower energy bills. The savings are a result of federal incentives aimed at encouraging the adoption of efficient electric appliances, vehicles, and heating systems.

Moreover, reducing emissions from the electricity sector will play a major role in cutting Canada’s overall greenhouse gas pollution. By 2050, it’s estimated that these regulations will reduce nearly 181 megatonnes of emissions, which is equivalent to removing over 55 million cars from the road. This is a crucial step in meeting Canada’s climate targets and mitigating the impacts of climate change, such as extreme weather events, which have already led to significant economic losses.

The economic benefits extend beyond savings on energy bills. The regulations and the broader clean electricity strategy will create substantial job opportunities. The clean energy sector, which includes jobs in wind, solar, and nuclear power, is poised for massive growth, and provinces like Alberta have outlined a path to clean electricity to support that momentum. It’s estimated that by 2030, the transition to clean electricity could create 400,000 new jobs, with further job growth projected for the years to come. These jobs are expected to include roles in both the construction and operation of new energy infrastructure, many of which will be unionized positions offering good wages and benefits.

To help meet the rising demand for clean energy, the government’s strategy emphasizes technological innovation and the integration of new energy sources, including market design updates such as proposed market changes that can enable investment. Renewable energy technologies such as wind and solar power have become increasingly cost-competitive, and their continued development is expected to reduce the overall cost of electricity generation. The regulations also encourage the adoption of energy storage solutions, which are essential for managing the intermittent nature of renewable energy sources.

In addition to the environmental and economic benefits, the Clean Electricity Regulations will help improve public health. Air pollution from fossil fuel power generation is a major contributor to respiratory illnesses and other health issues. By transitioning to clean energy sources, Canada can reduce harmful air pollutants, leading to better health outcomes and a lower burden on the healthcare system.

As Canada moves toward a net-zero electricity grid, including the federal 2035 target that some have criticized as changing goalposts in Saskatchewan, the Clean Electricity Regulations represent a comprehensive and flexible approach to managing the energy transition. With significant investments in clean energy technologies and the adoption of policies that ensure affordable electricity for all Canadians, the government is setting the stage for a cleaner, more sustainable future. These efforts will not only help Canada meet its climate goals but also create a thriving clean energy economy that benefits workers, businesses, and families across the country.

Hydro One delivery rates go up

Hydro One Rate Hike reflects Ontario Energy Board approval for higher delivery charges, impacting seasonal customers more than residential classes, funding infrastructure upgrades like wood pole and transformer replacements across Ontario's medium-density service areas.

 

Key Points

The Hydro One rate hike is an OEB-approved delivery charge increase to fund upgrades, with impacts on seasonal users.

✅ OEB-approved delivery rate increases retroactive to 2018

✅ Seasonal customers see larger monthly bill impacts than residential

✅ Funds pole, transformer replacements and tree trimming work

 

Hydro One seasonal customers will face bigger increases in their bills than the utility's residential customers as a result of an Ontario Energy Board approval of a rate hike, a topic drawing attention from a utilities watchdog in other provinces as well.

Hydro One received permission to increase its delivery charge, as large projects like the Meaford hydro generation proposal are considered across Ontario, retroactive to last year.

It says it needs the money to maintain and upgrade its infrastructure, including efforts to adapt to climate change, much of which was installed in the 1950s.

The utility is notifying customers that new statements reflect higher delivery rates which were not charged in 2018 and the first half of this year, due to delay in receiving the OEB's permission, similar to delays that can follow an energy board recommendation in other jurisdictions.

The amount that customers' bills will increase by depends not only on how much electricity they use, but also on which rate class they belong to, as well as policy decisions affecting remote connections such as the First Nations electricity line in northern Ontario.

For seasonal customers such as summer cottage owners, the impact on a typical user's bill will be 2.9 per cent more per month for 2018, and 1.7 per cent per month for 2019.

There will be further increases of 1.0 per cent, 1.4 per cent and 1.1 per cent per month in 2020, 2021 and 2022 respectively. 

Typical residential customers will experience smaller increases or rate freezes over the same period.

In the residential medium density class, the rate changes are a 2.0 per cent increase for last year, a decrease of 0.5 per cent this year, and an increase of 0.5 per cent in 2021. There will be no increases in 2020 and 2022.

 

Seasonal Rate Class — Estimated bill impact per month

2018 - 2.9 %

2019 - 1.7%

2020 - 1.0%

2021 - 1.4%

2022 - 1.1%

 

Residential Medium Density Rate Class — Estimated bill impact per month

2018 - 2.0%

2019 - -0.5% decrease

2020 - 0.0%

2021 - 0.5%

2022 - 0.0%

A Hydro One spokesperson told tbnewswatch.com that over the next three years, the utility's upgrading plan includes reliability investments such as replacing more than 24,000 wood poles across the province as well as numerous transformers.

In the Thunder Bay area, the spokesperson said, some of the revenue generated by the higher delivery rates will cover the cost of replacing more than 180 poles and trimming hazardous trees around 3,200 kilometres of overhead power lines while sharing electrical safety tips with customers.

Africa must quadruple power investment to supply electricity for all, IEA says

Africa Energy Investment must quadruple, says IEA, to deliver electricity access via grids, mini-grids, and stand-alone solar PV, wind, hydropower, natural gas, and geothermal, targeting $120 billion annually and 2.5% of GDP.

 

Key Points

Africa Energy Investment funds reliable, low-carbon electricity via grids, mini-grids, and renewables.

✅ Requires about $120B per year, or 2.5% of GDP

✅ Mix: grids, mini-grids, stand-alone solar PV and wind

✅ Targets reliability, economic growth, and electricity access

 

African countries will need to quadruple their rate of investment in their power sectors for the next two decades to bring reliable electricity to all Africans, as outlined in the IEA’s path to universal access analysis, an International Energy Agency (IEA) study published on Friday said.

If African countries continue on their policy trajectories, 530 million Africans will still lack electricity in 2030, the IEA report said. It said bringing reliable electricity to all Africans would require annual investment of around $120 billion and a global push for clean, affordable power to mobilize solutions.

“We’re talking about 2.5% of GDP that should go into the power sector,” Laura Cozzi, the IEA’s Chief Energy Modeller, told journalists ahead of the report’s launch. “India’s done it over the past 20 years. China has done it, with solar PV growth outpacing any other fuel, too. So it’s something that is doable.”

Taking advantage of technological advances and optimizing natural resources, as highlighted in a renewables roadmap, could help Africa’s economy grow four-fold by 2040 while requiring just 50% more energy, the agency said.

Africa’s population is currently growing at more than twice the global average rate. By 2040, it will be home to more than 2 billion people. Its cities are forecast to expand by 580 million people, a historically unprecedented pace of urbanization.

While that growth will lead to economic expansion, it will pile pressure on power sectors that have already failed to keep up with demand, with the sub-Saharan electricity challenge intensifying across the region. Nearly half of Africans - around 600 million people - do not have access to electricity. Last year, Africa accounted for nearly 70% of the global population lacking power, a proportion that has almost doubled since 2000, the IEA found.

Some 80% of companies in sub-Saharan Africa suffered frequent power disruptions in 2018, leading to financial losses that curbed economic growth.

The IEA recommended changing how power is distributed, with mini-grids and stand-alone systems like household solar playing a larger role in complementing traditional grids as targeted efforts to accelerate access funding gain momentum.

According to IEA Executive Director Fatih Birol, with the right government policies and energy strategies, Africa has an opportunity to pursue a less carbon-intensive development path than other regions.

“To achieve this, it has to take advantage of the huge potential that solar, wind, hydropower, natural gas and energy efficiency offer,” he said.

Despite possessing the world’s greatest solar potential, Africa boasts just 5 gigawatts of solar photovoltaics (PV), or less than 1% of global installed capacity, a slow green transition that underscores the scale of the challenge, the report stated.

To meet demand, African nations should add nearly 15 gigawatts of PV each year through 2040. Wind power should also expand rapidly, particularly in Ethiopia, Kenya, Senegal and South Africa. And Kenya should develop its geothermal resources.

Wasteful air conditioning adds $200 to summer energy bills, reveals BC Hydro

BC Hydro Air Conditioning Efficiency Tips help cut energy bills as HVAC use rises. Avoid inefficient portable AC units, set thermostats near 25 C, use fans and window shading, and turn systems off when unoccupied.

 

Key Points

BC Hydro's guidelines to lower summer power bills by optimizing A/C settings, fans, shading, and usage habits at home.

✅ Set thermostats to 25 C; switch off A/C when away

✅ Prefer fans and window shading; close doors/windows in heat

✅ Avoid multiple portable A/C units; choose efficient HVAC

 

BC Hydro is scolding British Columbians for their ineffective, wasteful and costly use of home air conditioners.

In what the electric utility calls “not-so-savvy” behaviour, it says many people are over-spending on air conditioning units that are poorly installed or used incorrectly.

"The majority of British Columbians will spend more time at home this summer because of the COVID-19 pandemic," BC Hydro says in a news release about an August survey of customers.

"With A/C use on the rise, there is evidence British Columbians are not cooling down efficiently, leading to higher summer electricity bills, as extreme heat boosts U.S. bills too this summer."

BC Hydro estimates some customers are shelling out $200 more on their summer energy bills than they need to during a record-breaking 2021 demand year for electricity.

The pandemic is compounding the demand for cool, comfortable air at home. Roughly two in five British Columbians between the ages of 25 and 50 are working from home five days a week.

However, it’s not just COVID-19 that is putting a strain on energy consumption and monthly bills, with drought affecting generation as well today.

About 90 per cent of people who use an air conditioner set it to a temperature below the recommended 25 Celsius, according to BC Hydro.

In fact, one in three people have set their A/C to the determinedly unseasonable temperature of 19 C.

Another 30 per cent are using more than one portable air conditioning unit, which the utility says is considered the most inefficient model on the market, and questions remain about crypto mining electricity use in B.C. today.

The use of air conditioners is steadily increasing in B.C. and has more than tripled since 2001, according to BC Hydro, with all-time high demand also reported in B.C. during recent heat waves. The demand for climate control is particularly high among condo-dwellers since apartments tend to trap heat and stay warmer.

This may explain why one in 10 residents of the Lower Mainland has three portable air conditioning units, and elsewhere Calgary's frigid February surge according to Enmax.

In addition, 30 per cent of people keep the air conditioning on for the sake of their pets while no one is home.

BC Hydro makes these recommendations to save energy and money on monthly bills while still keeping homes cooled during summer’s hottest days, and it also offers a winter payment plan to help manage costs:

Cool homes to 25 C in summer months when home; air conditioning should be turned off when homes are unoccupied.
In place of air conditioning, running a fan for nine hours a day over the summer costs $7.
Shading windows with drapes and blinds can help insulate a home by keeping out 65 per cent of the heat.
If the temperature outside a home is warmer than inside, keep doors and windows closed to keep cooler air inside.
Use a microwave, crockpot or toaster oven to avoid the extra heat produced by larger appliances, such as an oven, when cooking. Hang clothes to dry instead of using a dryer on hot days.

Climate change: Greenhouse gas concentrations again break records

Rising Greenhouse Gas Concentrations drive climate change, with CO2, methane, and nitrous oxide surging; WMO data show higher radiative forcing, elevated pre-industrial baselines, and persistent atmospheric concentrations despite Paris Agreement emissions pledges.

 

Key Points

Increasing atmospheric CO2, methane, and nitrous oxide levels that raise radiative forcing and drive warming.

✅ WMO data show CO2 at 407.8 ppm in 2018, above decade average

✅ Methane and nitrous oxide surged, elevating total radiative forcing

✅ Concentrations differ from emissions; sinks absorb about half

 

The World Meteorological Organization (WMO) says the increase in CO2 was just above the average rise recorded over the last decade.

Levels of other warming gases, such as methane and nitrous oxide, have also surged by above average amounts.

Since 1990 there's been an increase of 43% in the warming effect on the climate of long lived greenhouse gases.

The WMO report looks at concentrations of warming gases in the atmosphere rather than just emissions.

The difference between the two is that emissions refer to the amount of gases that go up into the atmosphere from the use of fossil fuels, such as burning coal for coal-fired electricity generation and from deforestation.

Concentrations are what's left in the air after a complex series of interactions between the atmosphere, the oceans, the forests and the land. About a quarter of all carbon emissions are absorbed by the seas, and a similar amount by land and trees, while technologies like carbon capture are being explored to remove CO2.

Using data from monitoring stations in the Arctic and all over the world, researchers say that in 2018 concentrations of CO2 reached 407.8 parts per million (ppm), up from 405.5ppm a year previously.

This increase was above the average for the last 10 years and is 147% of the "pre-industrial" level in 1750.

The WMO also records concentrations of other warming gases, including methane and nitrous oxide, and some countries have reported declines in certain potent gases, as noted in US greenhouse gas controls reports, though global levels remain elevated. About 40% of the methane emitted into the air comes from natural sources, such as wetlands, with 60% from human activities, including cattle farming, rice cultivation and landfill dumps.

Methane is now at 259% of the pre-industrial level and the increase seen over the past year was higher than both the previous annual rate and the average over the past 10 years.

Nitrous oxide is emitted from natural and human sources, including from the oceans and from fertiliser-use in farming. According to the WMO, it is now at 123% of the levels that existed in 1750.

Last year's increase in concentrations of the gas, which can also harm the ozone layer, was bigger than the previous 12 months and higher than the average of the past decade.

What concerns scientists is the overall warming impact of all these increasing concentrations. Known as total radiative forcing, this effect has increased by 43% since 1990, and is not showing any indication of stopping.

There is no sign of a slowdown, let alone a decline, in greenhouse gases concentration in the atmosphere despite all the commitments under the Paris agreement on climate change and the ongoing global energy transition efforts," said WMO Secretary-General Petteri Taalas.

"We need to translate the commitments into action and increase the level of ambition for the sake of the future welfare of mankind," he added.

"It is worth recalling that the last time the Earth experienced a comparable concentration of CO2 was three to five million years ago. Back then, the temperature was 2-3C warmer, sea level was 10-20m higher than now," said Mr Taalas.

The UN Environment Programme will report shortly on the gap between what actions countries are taking to cut carbon, for example where Australia's emissions rose 2% recently, and what needs to be done to keep under the temperature targets agreed in the Paris climate pact.

Preliminary findings from this study, published during the UN Secretary General's special climate summit last September, indicated that emissions continued to rise during 2018, although global emissions flatlined in 2019 according to the IEA.

Both reports will help inform delegates from almost 200 countries who will meet in Madrid next week for COP25, following COP24 in Katowice the previous year, the annual round of international climate talks.
