RWE

A battery doesn't store electricity. It stores chemical energy.   The picture most of us have in mind is roughly this: a battery is a tank, electricity flows in when we charge it, electricity flows out when we use it. That's actually not quite right. Electricity can’t really be stored in a battery. What a battery actually does is convert it. When we charge a cell, we convert electrical energy into chemical energy inside the battery materials. When we discharge it, we reverse this process.   Language shapes how we think. If we talk about batteries as containers, we underestimate what's happening inside them. If we talk about them as electrochemical assets, questions around materials, lifespan and recycling immediately change.

Impact beyond the workplace 🤝    The Hands-on Heroes Award at RWE Supply & Trading celebrates employees who go above and beyond to support their local communities through volunteering and personal initiative. It recognises the real impact they create outside of their day-to-day roles and highlights the importance of giving back in meaningful, practical ways.    Each winner’s chosen charity benefits from the wider spirit of this initiative, helping extend their impact even further.     Swipe through to discover the organisations being supported. 👉     Your energy has impact at #TeamRWE https://lnkd.in/epx4pFtN William Draper-Barr Jan Sporing #OurEnergyHasImpact #HandsOnHeroes #Volunteering 

Eight hours.   That's how long Australia's longest-duration battery can now deliver power at full output. Located next to our Limondale Solar Farm in New South Wales, the 50 MW Limondale battery storage system has just received the official sign-off from Australian Energy Market Operator (AEMO) and Transgrid to move from commissioning to full operations.   Eight-hour duration means the battery can help reduce network pressures during peak demand and support a more flexible, secure electricity system. In combination with our solar plant, it’s a great hybrid project: The sun produces, the battery holds, the grid receives.   Thank you to #TeamRWE, our other partners Tesla, Beon Energy Solutions, Lumea, as well as the Government of New South Wales (NSW Government) for delivering this project successfully together.

I am delighted to share we have secured a long-term Capacity Investment Scheme (CIS) contract for RWE’s 1.1 GW Theodore onshore wind development project, located in Central Queensland, Australia. The CIS underwrites the project with a set revenue floor and ceiling. The total investment volume to realise Theodore onshore wind farm amounts to AU$3 billion. The proposed project would incorporate a wind farm with up to 170 turbines as well as a battery storage facility and would generate enough electricity to power about 500,000 Queensland homes. The onshore wind development project is well positioned to deliver long-term value, contributing to energy security and stable, affordable electricity in Queensland. The CIS award underscores the project’s strong fundamentals, local backing, and scale, and it supports unlocking sound financing. With its state Development Application secured in June 2025, the site is working through the Federal Environment Protection and Biodiversity Conversation (EPBC) process. Construction is expected to start later this year, subject to EPBC approvals and final investment decision.

A solar field next to dairy cows is no coincidence. It’s a glimpse into Europe’s energy future: producing food and electricity on the same land.   Solar is now the world’s cheapest source of electrcity and powers the equivalent of half of all European homes. Across Europe, meeting solar and renewables targets can reduce energy price spikes by up to 20 percent, helping create a more stable and affordable system.   At RWE, we operate more than 100 solar projects across Europe, the Americas and Australia, and are continuously expanding our expertise in agrivoltaics, where renewable energy generation and agriculture work side by side. For more certainty and lower bills. Because stability matters. Be part of #abrighttoday. Pass it on: www.abright.today

The Age of Electricity is here. And it‘s been a long time coming.   The latest report from the International Energy Agency (IEA) makes the trend hard to miss: In 2025, global electricity demand grew more than twice as fast as overall energy demand. And the gap has been widening for over a decade.   The drivers are familiar: AI and data centres, heating and cooling, and the electrification of transport and a growing share of industrial processes are all pulling electricity demand upwards. What‘s new is the pace at which these forces are converging.   The more the energy supply shifts towards mostly homegrown electrons, the lower the dependence on fossil fuel imports. This underscores the structural case for electrification, and it gets stronger each year.   The trend is clear. For the momentum to hold, the supply side needs to keep up – and that means scaling renewables, grids, storage, and flexible capacity at the same speed as demand. That is where the framework conditions are decisive, and where we in the industry must deliver.   The Age of Electricity is no longer a forecast. Let’s build for it.

If you've ever stood near a wind turbine, you'll know the feeling. Viewed from below or from a distance, the blades look almost lazy from below. Slow, deliberate, calm.   Well, they're not!   The hub of a modern offshore turbine turns at just a handful of rotations per minute. But the blade attached to it stretches well past 100 metres. This means, that during each rotation, the outermost tip travels more than 600 metres through the air – reaching speeds of up to 300 km/h, which is roughly the top speed of a Formula 1 car on a long straight. The hub is the calm part. The tip is something else entirely.   At those speeds, a raindrop hits the blade's leading edge like a small projectile. Over years, that causes erosion – which has to be engineered against from the very first design sketch. Coatings, foils, protective shells: leading-edge protection is one of the most active fields of blade engineering today.   So what looks gentle from the coastline is, at the outermost point, one of the most extreme working environments in energy. Slow rotation, fast tips – offshore turbines are engineered for both.

Why do wind turbines have three blades? Not two. Not four. Not five. The answer is that it's a deliberate compromise between several things that don't naturally align with each other: how much energy a rotor can extract, how stable it remains while doing it, and how much it costs to build. Two blades would be cheaper, but louder, more uneven and less efficient. Four would add weight and cost, but almost no extra energy. Three is the point where physics, materials and economics meet.   It's one of those engineering decisions that becomes invisible as soon as it has been implemented. Every wind farm on the horizon and every turbine off our coastlines, every onshore site across our portfolio – they all share the same answer to the same question.   Three blades: Not by accident, but by optimisation.
