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.

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.

⚡ 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.

⚡ 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.

🇵🇭 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.

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.

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.

🔄 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.

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.

🏭 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 👇

🛰️ 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.

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...
👁️ We applied our rooftop solar estimation methodology to Thailand, and found ~3.60 GWac installed nationwide... notably higher than official 2023 figures.
Get all the details here 👉🏻 www.transitionzero.org/insights/a-n...
🇹🇭 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...
We have big ambitions, and we're very proud of this milestone and grateful to be building it with Google.

⚡ By bringing Gemini into the product, we’re aiming to go further: helping users move from questions to structured scenarios even more quickly, making it easier to navigate complex assumptions, and speeding up the most challenging planning decisions...
During Singapore International Energy Week last year, we shared the exciting news that we are integrating Google’s Gemini into Scenario Builder.
❓ Scenario Builder is simple, accessible, and no-code — so that anyone, not just energy specialists, can explore and compare possible energy futures...
Scenario Builder allows users to explore the many potential pathways to meet these challenges, using a capacity expansion model at the grid zone level.

🏭 Despite this, coal remains the primary generation source, with over 30GW of coal plants already in the pipeline.
📈 In addition, India’s electricity demand is set to be one of the fastest-growing amongst major economies, possibly tripling by 2050 compared to current levels...
🎯 last July, India announced that it had met the target of 50% of installed electricity capacity from non fossil fuel sources.
How? Competitive bidding, strong policy support, and generous solar and wind resources...
🇮🇳 India is now live on our Scenario Builder platform!

☀️ One of the most striking recent developments is the rapid growth of distributed solar. But at the same time, Pakistan has added large volumes of LNG and imported coal capacity over the past decade, locking in fixed costs that are increasingly misaligned with actual demand and fuel affordability...
Pakistan's power sector is a major contributor to the country's macroeconomic and fiscal stress. It's a story of weakened grid demand, high capacity payments, persistent circular debt, and a generation mix that has evolved very differently from what policymakers originally envisaged...
🇵🇰 We're excited to announce the addition of Pakistan to our Scenario Builder platform!
