3 TW of clean energy is stuck in grid queues - more than the entire global coal fleet. Planning systems are the bottleneck. Matt Gray and Fiona Howarth on why electricity planning needs a software upgrade now: www.transitionzero.org/insights/pla...

Energy planning tools haven't kept pace with the energy transition.💡 TransitionZero CEO Matt Gray and Chair Fiona Howarth make the case for why the electricity planning system needs a software upgrade - and what it would take to fix it. Read the op-ed: www.transitionzero.org/insights/pla...

We've open-sourced our 24/7 carbon-free energy modelling work across five Asian markets, built with support from Google.org using the PyPSA framework. 🔗 Code, data, and results on GitHub: github.com/transition-zero/tza-google-cfe

An analysis from @transitionzero.org shows that, for Pakistan, investing US$500m in batteries and renewables could save up to US$2.87b in RLNG costs and avoid #emissions spikes tied to global fuel shocks. Read more: www.transitionzero.org/insights/bat...

108,346 solar facilities. 1,331 GW detected globally. Capacity up 6.8% in one quarter. Spain leads Europe at 46 GW, and its solar-heavy grid is proving far more resilient to the Iran crisis than fossil-dependent neighbours. Q1 2026 data is live: www.transitionzero.org/insights/spa...

The Philippines could incur US$90.5bn in fossil system costs through 2040. 81% of that is fuel and variable costs. New modelling shows solar grows eightfold and 12 GW of battery gets built. But contract lock-in keeps coal and gas running. 🔗 bit.ly/4e8ITJ9

Grids will do the heavy lifting in the energy transition. They enable renewables, reduce costs, and create clean power trade routes. ⚡ But expansion is complex. How much? Where? What are the trade-offs? We explored these questions: www.transitionzero.org/insights/cab...

It's #EarthDay2026. Progress happens when people show up. For energy modelling, that means showing up with evidence.🌍 But modelling software is expensive. This is one reason we built Scenario Builder: a free, no-code energy system modelling platform. ➡️ bit.ly/46C5iKi

New Scenario Builder modelling shows the Java-Sumatra interconnection could push renewables to 48% by 2040, exceeding national targets.🔌 🔗 Read the full analysis: www.transitionzero.org/insights/jav...

TransitionZero turns 5 today. 🎂 5 years ago: a simple question Today: a platform helping to drive energy decisions across 3 continents Thank you to everyone who's been part of this journey. The best is ahead. transitionzero.org

Coal outages in the Philippines surged 200% in 2025. ⚠️ The worst performers are the most contracted. When these plants go offline, supply tightens, potentially pushing up consumer prices through higher-cost alternatives. 📊 New TZ-CAT analysis: bit.ly/4svoq4E

Pakistan’s evening peak in 2026 reveals just how fragile a fossil fuel–dependent grid really is. New modelling by Renewables First using TransitionZero’s Scenario Builder shows what happens when fuel prices spike. 📊 Full analysis: www.transitionzero.org/insights/bat...

The Philippines signed 75 emergency coal contracts since 2022. Some cost 32 to 68% more than long-term deals. Without firm alternatives, supply gaps get filled with expensive short-term coal. New TZ-CAT analysis: www.transitionzero.org/insights/phi...

Japan can reach 50% renewable electricity with very little clean energy going to waste. But going further — towards a fully clean power system — will require something more: flexibility. 🔗 Read the full blog: www.transitionzero.org/insights/jap... @clientearth.bsky.social

Passionate about the energy transition? Good news, we're currently hiring for the following roles to join our friendly team: ⚡ Software Engineer ⚡ Engineering Manager ⚡ Product Manager ⚡ Operations Manager Find out more and apply: www.transitionzero.org/careers?utm_...

⚡ Can Japan reach 50% renewable electricity without wasting power? TransitionZero and ClientEarth’s updated analysis of OCCTO’s 2021 modelling of Japan’s 2040 power system suggests it can. 📖 Read the full analysis: www.transitionzero.org/insights/jap...

⚡ Cutting coal doesn’t always mean more renewables. In Peninsular Malaysia, coal reductions could mostly shift to gas instead — up to 69–90% in our analysis. But Sarawak shows a cleaner pathway, where coal cuts could be replaced by hydropower. www.transitionzero.org/insights/coa...

🇵🇭 Could the Philippines exceed its renewable energy targets? Our modelling suggests renewables could reach ~54% of electricity generation by 2040, surpassing the 50% policy target, with solar driving most of the growth. Read more: www.transitionzero.org/insights/the...

Agentic modelling is here, but getting it right is hard. AI agents are probabilistic. Energy system models are deterministic. Our Head of Machine Learning explains how and why we built AMP, our AI modelling assistant. 🔗 bit.ly/4r4PEOP

Bangladesh’s rooftop solar push is gaining momentum, but progress remains modest. 🛰 Our satellite analysis estimates ~370 MWp installed as of Jan 2026, far below the 3,000 MWp target. 🔗 Full analysis → bit.ly/4ub1aLp

Meet AMP — TransitionZero’s AI modelling assistant. Understand scenarios, diagnose infeasibilities, and interpret results faster. Now in beta in Scenario Builder, our no-code power system modelling platform. 🔗 bit.ly/46C5iKi

🔄 Most energy models don’t talk to each other. Long-term planning ≠ hourly dispatch. Built in isolation, they don’t align. We built an interoperable data model linking TZ-OSeMOSYS and PyPSA — one common language for capacity expansion and dispatch. Read more: bit.ly/4rMhuAJ

Malaysia’s data centres now use 3% of Peninsular electricity — triple the year before. Coal retirements after 2029 create a turning point. If clean energy and imports don’t scale fast enough, gas fills the gap, but will stay on for decades. Read more 👇 www.transitionzero.org/insights/mal...

🏭 Can coal plants in Southeast Asia run more flexibly? Technically, sometimes. Commercially? Much harder. Long-term PPAs, two-part tariffs & must-run clauses lock coal into baseload — even as solar and wind grow. Part II of our coal flexibility series explores why 👇 🔗 bit.ly/4aAHLut

🛰️ Indonesia's rooftop solar puzzle: plenty of sunshine, but minimal scale. Our satellite analysis found ~600 MWp installed - well short of the national target. The catch? 87% is concentrated in Java. The rest of the archipelago? Essentially zero. 🔗 Find out more: bit.ly/40eEoV2

Our Co-head of Modelling Abhishek Shivakumar will be in Delhi this week for the Google.org Impact Summit APAC 2026 (17-18 February) to share our work on building a no-code energy modelling platform. 💡 If you’ll be around, please reach out to Abhi directly — He’d love to connect!

🎉 2025 was a huge year for our Solar Asset Mapper, TZ-SAM. 📈 We are now tracking over 106k individual solar PV assets all around the globe, covering 31,456km with a combined capacity of 1,246 GW. ☀️ Dive into the latest release 👉🏻  www.transitionzero.org/insights/a-y...

🇹🇭 Thailand was once a solar energy pioneer of Southeast Asia, but in recent years, capacity growth has remained fairly flat. 🔍 Now, the rooftop solar market is back in focus as the government pushes a ‘Quick Big Win’ package to accelerate deployment, especially of residential systems...
