Solar-Wind-Water West Africa integrates hydropower with solar and wind to boost grid flexibility, clean electricity, and decarbonization, leveraging the West African Power Pool and climate data modeling reported in Nature Sustainability.

Key Points

A strategy using hydropower to balance solar and wind, enabling reliable, low-carbon electricity across West Africa.

✅ Hydropower dispatch covers solar and wind shortfalls.

✅ Regional interconnection via West African Power Pool.

✅ Cuts CO2 versus gas while limiting new dam projects.

Hydropower plants can support solar and wind power, rather unpredictable by nature, in a climate-friendly manner. A new study in the scientific journal Nature Sustainability has now mapped the potential for such "solar-wind-water" strategies for West Africa: an important region where the power sector is still under development, amid IEA investment needs for universal access, and where generation capacity and power grids will be greatly expanded in the coming years. "Countries in West Africa therefore now have the opportunity to plan this expansion according to strategies that rely on modern, climate-friendly energy generation," says Sebastian Sterl, energy and climate scientist at Vrije Universiteit Brussel and KU Leuven and lead author of the study. "A completely different situation from Europe, where power supply has been dependent on polluting power plants for many decades - which many countries now want to rid themselves of."

Solar and wind power generation is increasing worldwide and becoming cheaper and cheaper. This helps to keep climate targets in sight, but also poses challenges. For instance, critics often argue that these energy sources are too unpredictable and variable to be part of a reliable electricity mix on a large scale, though combining multiple resources can enhance project performance.

"Indeed, our electricity systems will have to become much more flexible if we are to feed large amounts of solar and wind power into the grid. Flexibility is currently mostly provided by gas power plants. Unfortunately, these cause a lot of CO2 emissions," says Sebastian Sterl, energy and climate expert at Vrije Universiteit Brussel (VUB) and KU Leuven. "But in many countries, hydropower plants can be a fossil fuel-free alternative to support solar and wind energy. After all, hydropower plants can be dispatched at times when insufficient solar and wind power is available."

The research team, composed of experts from VUB, KU Leuven, the International Renewable Energy Agency (IRENA), and Climate Analytics, designed a new computer model for their study, running on detailed water, weather and climate data. They used this model to investigate how renewable power sources in West Africa could be exploited as effectively as possible for a reliable power supply, even without large-scale storage, in line with World Bank support for wind in developing countries. All this without losing sight of the environmental impact of large hydropower plants.

"This is far from trivial to calculate," says Prof. Wim Thiery, climate scientist at the VUB, who was also involved in the study. "Hydroelectric power stations in West Africa depend on the monsoon; in the dry season they run on their reserves. Both sun and wind, as well as power requirements, have their own typical hourly, daily and seasonal patterns. Solar, wind and hydropower all vary from year to year and may be impacted by climate change, including projections that wind resources shift southward in coming years. In addition, their potential is spatially very unevenly distributed."

West African Power Pool

The study demonstrates that it will be particularly important to create a "West African Power Pool", a regional interconnection of national power grids to serve as a path to universal electricity access across the region. Countries with a tropical climate, such as Ghana and the Ivory Coast, typically have a lot of potential for hydropower and quite high solar radiation, but hardly any wind. The drier and more desert-like countries, such as Senegal and Niger, hardly have any opportunities for hydropower, but receive more sunlight and more wind. The potential for reliable, clean power generation based on solar and wind power, supported by flexibly dispatched hydropower, increases by more than 30% when countries can share their potential regionally, the researchers discovered.

All measures taken together would allow roughly 60% of the current electricity demand in West Africa to be met with complementary renewable sources, despite concerns about slow greening of Africa's electricity, of which roughly half would be solar and wind power and the other half hydropower - without the need for large-scale battery or other storage plants. According to the study, within a few years, the cost of solar and wind power generation in West Africa is also expected to drop to such an extent that the proposed solar-wind-water strategies will provide cheaper electricity than gas-fired power plants, which currently still account for more than half of all electricity supply in West Africa.

Better ecological footprint

Hydropower plants can have a considerable negative impact on local ecology. In many developing countries, piles of controversial plans for new hydropower plants have been proposed. The study can help to make future investments in hydropower more sustainable. "By using existing and planned hydropower plants as optimally as possible to massively support solar and wind energy, one can at the same time make certain new dams superfluous," says Sterl. "This way two birds can be caught with one stone. Simultaneously, one avoids CO2 emissions from gas-fired power stations and the environmental impact of hydropower overexploitation."

Global relevance

The methods developed for the study are easily transferable to other regions, and the research has worldwide relevance, as shown by a US 80% study on high variable renewable shares. Sterl: "Nearly all regions with a lot of hydropower, or hydropower potential, could use it to compensate shortfalls in solar and wind power." Various European countries, with Norway at the front, have shown increased interest in recent years to deploy their hydropower to support solar and wind power in EU countries. Exporting Norwegian hydropower during times when other countries undergo solar and wind power shortfalls, the European energy transition can be advanced.

EU Gas Price Cap Strategies aim to curb inflation during an energy crisis by capping wholesale gas and electricity generation costs, balancing supply and demand, mitigating subsidies, and safeguarding supply security amid Russia-Ukraine shocks.

Key Points

Temporary EU measures to cap gas and power prices, curb inflation, manage demand, and protect supply security.

✅ Flexible temporary price limits to secure gas supplies

✅ Framework cap on gas for electricity generation with demand checks

✅ Risk: subsidies, higher demand, and market distortions

The European Commission has outlined possible strategies to cap gas prices as the bloc faces a looming energy crisis this winter. 

Member states are divided over the emergency measures designed to pull down soaring inflation amid Russia's war in Ukraine. 

One proposal is a temporary "flexible" limit on gas prices to ensure that Europe can continue to secure enough gas, EU energy commissioner Kadri Simson said on Tuesday. 

Another option could be an EU-wide "framework" for a price cap on gas used to generate electricity, which would be combined with measures to ensure gas demand does not rise as a result, she said.

EU leaders are meeting on Friday to debate gas price cap strategies amid warnings that Europe's energy nightmare could worsen this winter.

Last week, France, Italy, Poland and 12 other EU countries urged the Commission to propose a broader price cap targeting all wholesale gas trade. 

But Germany -- Europe's biggest gas buyer -- and the Netherlands are among those opposing electricity market reforms within the bloc.

Russia has slashed gas deliveries to Europe since its February invasion of Ukraine, with Moscow blaming the cuts on Western sanctions imposed in response to the invasion, as the EU advances a plan to dump Russian energy across the bloc.

Since then, the EU has agreed on emergency laws to fill gas storage and windfall profit levies to raise money to help consumers with bills. 

Price cap critics
One energy analyst told Euronews that an energy price cap was an "unchartered territory" for the European Union. 

The EU's energy sector is largely liberalised and operates under the fundamental rules of supply and demand, making rolling back electricity prices complex in practice.

"My impression is that member states are looking at prices and quantities in isolation and that's difficult because of economics," said Elisabetta Cornago, a senior energy researcher at the Centre for European Reform.

"It's hard to picture such a level of market intervention This is uncharted territory."

The energy price cap would "quickly start costing billions" because it would force governments to continually subsidise the difference between the real market price and the artificially capped price, another expert said. 

"If you are successful and prices are low and you still get gas, consumers will increase their demand: low price means high demand. Especially now that winter is coming," said Bram Claeys, a senior advisor at the Regulatory Assistance Project.

Texas Power Grid Blackouts loom as ERCOT forecasts record air conditioning load, tight reserve margins, peak demand spikes, and rising natural gas prices; heatwaves could trigger brownouts without added solar, storage, and demand response.

Key Points

Texas Power Grid Blackouts are outages when AC-driven peak demand and ERCOT reserves outstrip supply during heatwaves.

✅ ERCOT forecasts record AC load and tight reserve margins.

✅ Coal retirements cut capacity; gas and solar additions lag.

✅ Peak prices, brownouts likely without storage and demand response.

U.S. Air conditioning related electricity usage will break records and may cause blackouts across the U.S. and in Texas this summer. Power grid operators are forecasting that electricity supplies will exceed demands during the summer months.

Most of Texas will face severe electricity shortages because of hot temperatures, air conditioning, and a strong economy, with millions at risk of electricity shut-offs during extreme heat, Bill Magness the president of the Electric Reliability Council of Texas (ERCOT) told the Associated Press. Magness thinks the large numbers people moving to Texas for retirement will increase the demand for air conditioning and electricity use. Retired people are more likely to be home during the day when temperatures are high – so they are more likely to turn up the air conditioner.

Around 50% of all electricity in Texas is used for air conditioning and 100% of homes in Texas have air conditioners, Forbes reported. That means just a few hot days can strain the grid and a heatwave can trigger brownouts and blackouts, in a system with more blackouts than other developed countries on average.

The situation was made worse by Vistra Energy’s decision to close more coal-fired power plants last year, The Austin American Statesman reported. The closed plants; Big Brown, Sadow, and Monticello, generated around 4,100 megawatts (4.1 million watts) of electricity, enough generation capacity to power two million homes, The Waco Herald-Tribune reported.

Texas Electric Grid Might Not Meet Demand

Texas’s grid has never operated without those plants will make this summer a test of its capacity. Texas only has a 6% reserve of electricity that might fall will because of problems like downed lines or a power plant going offline.

A Vistra subsidiary called Luminant has added around 8,000 megawatts of generation capacity from natural-gas burning plants, The Herald-Tribune reported. Luminant also plans to open a giant solar power plant in Texas to increase grid capacity.

The Texas grid already reached peak capacity in May because of unexpectedly high demand and technical problems that reflect more frequent outages in many states, Houston Public Media reported. Grid capacity fell because portions of the system were offline for maintenance.

Some analysts have suggested starting schools after Labor Day to shift peak August demand, potentially easing stress on the grid.

Electricity Reserves are Tight in Texas

Electricity reserves will be very tight on hot summer days in Texas this summer, Magness predicted. When the thermometer rises, people crank up the air conditioner which burns more electricity.

The grid operator ERCOT anticipates that Texas will need an additional 1,600 megawatts of electricity this summer, but record-high temperatures can significantly increase the demand. If everything is running correctly, Texas’s grid can produce up to 78,184 megawatts of electricity.

“The margin between absolute peak power usage and available peak supply is tighter than in years past,” Andrew Barlow, a spokesman for Texas’s Public Utility Commission admitted.

Around 90% of Texas’s grid has enough generating capacity, ERCOT estimated. That means 10% of Texas’s power grid lacks sufficient generating capacity which increases the possibility of blackouts.

Even if the electricity supply is adequate electricity prices can go up in Texas because of higher natural gas prices, Forbes reported. Natural gas prices might go up over the summer because of increased electricity demands. Texas uses between 8% and 9% of America’s natural gas supply to generate electricity for air conditioning in the summer.

Be Prepared For Blackouts This Summer.

Texas’s problems might affect other regions including neighboring states such as Oklahoma, Arkansas, Louisiana, and New Mexico and parts of Mexico, as lawmakers push to connect Texas’s grid to the rest of the nation to improve resilience because those areas are connected to the same grid. Electricity from states like Colorado might be diverted to Texas in case of power shortages there.

Beyond the U.S., Canadian electricity grids are increasingly exposed to harsh weather that can ripple across markets as well.

Home and business owners can avoid summer blackouts by tapping sources of Off-Grid electricity. The two best sources are backup battery storage and solar panels which can run your home or business if the grid runs dry.

If you have family members with health problems who need air conditioning, or you rely on a business or freelance work that requires electricity for income, backup power is vital. Those who need backup electricity for their business should be able to use the expense of installing it as a tax deduction.

Having backup electricity available might be the only way for Texans to keep cool this summer.

GE Wind Turbine Collapse Brazil raises safety concerns at Omega Energia's Delta VI wind farm in Maranhe3o, with GE Renewable Energy probing root-cause of turbine failure after a worker injury and similar incidents in 2024.

Key Points

An SEO focus on the Brazil GE turbine collapse, its causes, safety investigation, and related 2024 incidents.

✅ Incident at Omega Energia's Delta VI, Maranhao; one worker injured

✅ GE Renewable Energy conducts root-cause investigation and containment

✅ Fifth GE turbine collapse in 2024 across Brazil and the United States

A GE Renewable Energy turbine collapsed at a wind farm in north-east Brazil, injuring a worker and sparking a probe into the fifth such incident this year, the manufacturer confirmed.

One of the manufacturer’s GE 2.72-116 turbines collapsed at Omega Energia’s Delta VI project in Maranhão, which was commissioned in 2018.

Three GE employees were on site at the time of the collapse on Tuesday (3 September), the US manufacturer confirmed, even as U.S. offshore wind developers signal growing competitiveness with gas. 

One worker was injured and is currently receiving medical treatment, GE added.

"We are working to determine the root cause of this incident and to provide proper support as needed," it said

The turbine collapse in Brazil is the fifth such incident involving GE turbines this year, even as the UK's biggest offshore windfarm begins power supply this week, underscoring broader sector momentum.

On 16 February, a turbine collapsed at NextEra Energy Resources’ Casa Mesa wind farm in New Mexico, US, while giant wind components were being transported to a project in Saskatchewan, Canada. The site uses GE’s 2.3-116 and 2.5-127 models.

The New Mexico incident was followed by another collapse in the US — as a Scottish North Sea wind farm resumed construction after Covid-19 — this time a GE 2.4-107 unit at Tradewind Energy’s Chisholm View 2 project in Oklahoma on 21 May.

Two GE turbines then collapsed at projects in July: a 2.5-116 unit at Invenergy’s Upstreamwind farm in Nebraska on 5 July, followed by a 1.7-103 model at the Actis Group-owned Ventos de São Clemente complex in Pernambuco, north-eastern Brazil, even as tidal power in Scotland generated enough electricity to power nearly 4,000 homes.

No employees were injured in the first four turbine collapses of the year, in contrast with concerns at a Hawaii geothermal plant over potential meltdown risk.

In response to the latest incident, GE Renewable Energy added: "It is too early to speculate about the root cause of this week’s turbine collapse.

"Based on our learnings from the previous turbine collapses, we have teams in place focused on containing and resolving these issues quickly, to ensure the safe and reliable operation of our turbines."

UK Electricity-Gas Price Decoupling aims to reform wholesale electricity pricing under the Energy Security Bill, shielding households from gas price spikes, supporting renewables, and easing the cost-of-living crisis through market redesign and transparent tariffs.

Key Points

Policy to decouple power prices from gas via the Energy Security Bill, stabilizing bills and reflecting renewables

✅ Breaks gas-to-power pricing link to cut electricity costs

✅ Reduces volatility; shields households from global gas shocks

✅ Highlights benefits of renewables and market transparency

Britons could be handed relief on rocketing household bills under Government plans to sever the link between the prices of gas and electricity, including proposals to restrict energy prices in the market, it has emerged.

Ministers are set to bring forward new laws under the Energy Security Bill to overhaul the UK's energy market in the face of the current cost-of-living crisis.

They have promised to provide greater protection for Britons against global fluctuations in energy prices, through a price cap on bills among other measures.

The current worldwide crisis has been exacerbated by the Ukraine war, which has sent gas prices spiralling higher.

Under the current make-up of Britain's energy market, soaring natural gas prices have had a knock-on effect on electricity costs.

But it has now been reported the new legislation will seek to prevent future shocks in the global gas market having a similar impact on electricity prices.

Yet the overhaul might not come in time to ease high winter energy costs for households ahead of this winter.

According to The Times, Business Secretary Kwasi Kwarteng will outline proposals for reforms in the coming weeks.

These will then form part of the Energy Security Bill to be introduced in the autumn, with officials anticipating a decrease in energy bills by April.

The newspaper said the plans will end the current system under which the wholesale cost of gas effectively determines the price of electricity for households.

Although more than a quarter of Britain's electricity comes from renewable sources, under current market rules it is the most expensive megawatt needed to meet demand that determines the price for all electricity generation.

This means that soaring gas prices have driven up all electricity costs in recent months, even though only around 40% of UK electricity comes from gas power stations.

Energy experts have compared the current market to train passengers having to pay the peak-period price for every journey they make.

One Government source told The Times: 'In the past it didn’t really matter because the price of gas was reasonably stable.

'Now it seems completely crazy that the price of electricity is based on the price of gas when a large amount of our generation is from renewables.'

It was also claimed ministers hope the reforms will make the market more transparent and emphasise to consumers the benefits of decarbonisation, amid an ongoing industry debate over free electricity for consumers.

A Government spokesperson said: 'The high global gas prices and linked high electricity prices that we are currently facing have given added urgency to the need to consider electricity market reform.

SDG&E Ramona Microgrid delivers renewable energy and battery storage for wildfire mitigation, grid resilience, and PSPS support, powering the Cal Fire Air Attack Base with a 500 kW, 2,000 kWh lithium-ion system during outages.

Key Points

A renewable, battery-backed microgrid powering Ramona's Air Attack Base, boosting wildfire response and PSPS resilience.

✅ 500 kW, 2,000 kWh lithium-ion storage replaces diesel

✅ Keeps Cal Fire and USFS aircraft operations powered

✅ Supports PSPS continuity and rural water reliability

It figures to be another dry year — with the potential to spark wildfires in the region. But San Diego Gas & Electric just completed a renewable energy upgrade to a microgrid in Ramona that will help firefighters and reduce the effects of power shutoffs to backcountry residents.

The microgrid will provide backup power to the Ramona Air Attack Base, helping keep the lights on during outages, home to Cal Fire and the U.S. Forest Service's fleet of aircrafts that can quickly douse fires before they get out of hand.

"It gives us peace of mind to have backup power for a critical facility like the Ramona Air Attack Base, especially given the fact that fire season in California has become year-round," Cal Fire/San Diego County Fire Chief Tony Mecham said in a statement.

The air attack base serves as a hub for fixed-wing aircraft assigned to put out fires. Cal Fire staffs the base throughout the year with one two airtankers and one tactical aircraft. The base also houses the Forest Service's Bell 205 A++ helicopter and crew to protect the Cleveland National Forest. Aircraft for both CalFire and the Forest Service can also be mobilized to help fight fires throughout the state.

This summer, the Ramona microgrid won't have to rely on diesel generation. Instead, the facility next to the town's airport will be powered by a 500 kilowatt and 2,000 kilowatt-hour lithium-ion battery storage system that won't generate any greenhouse gas emissions.

"What's great about it, besides that it's a renewable resource, is that it's a permanent installation," said Jonathan Woldemariam, SDG&E's director of wildfire mitigation and vegetation management. "In other words, we don't have to roll a portable generator out there. It's something that can be leveraged right there because it's already installed and ready to go."

Microgrids have taken on a larger profile across the state because they can operate independently of the larger electric grid, where repairing California's grid is an ongoing challenge, thus allowing small areas or communities to keep the power flowing for hours at a time during emergencies.

That can be crucial in wildfire-prone areas affected by Public Safety Power Shutoffs, or PSPS, the practice in which investor-owned utilities in California de-energize electrical power lines in a defined area when conditions are dry and windy in order to reduce the risk of a power line falling and igniting a wildfire, while power grid upgrades move forward statewide.

Rural and backcountry communities are particularly hard hit when the power is pre-emptively cut off because many homes rely on water from wells powered by electricity for their homes, horses and livestock.

In addition to Ramona, SDG&E has established microgrids in three other areas in High Fire Threat Districts:

The microgrids in Butterfield Ranch and Shelter Valley run on diesel power but the utility plans to complete solar and battery storage systems for each locale by the end of next year, as other regions develop new microgrid rules to guide deployment.

SDG&E has a fifth microgrid in operation — in Borrego Springs, which in 2013 became the first utility-scale microgrid in the country. It provides grid resiliency to the roughly 2,700 residents of the desert town and serves as a model for integrated microgrid projects elsewhere in delivering local electricity. While the Borrego Springs microgrid is not located in a High Fire Threat District, "when and if any power is turned off, especially the power transmission feed that goes to Borrego, we can support the customers using the microgrid out there," Woldemariam said.

Microgrid costs can be higher than conventional energy systems, even as projected energy storage revenue grows over the next decade, and the costs of the SDG&E projects are passed on to ratepayers. As per California Public Utilities Commission rules, the financial details for each of microgrid are kept confidential for at least three years.

SDG&E's microgrids are part of the utility's larger plan to reduce wildfire risk that SDG&E files with the utilities commission. In its wildfire plan for 2020 through 2022, SDG&E expected to spend $1.89 billion on mitigation measures.
