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...

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

⚡ 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

🇹🇼 In 2024, the Taiwanese government raised its 2030 emissions reduction target from 24% to 28% below 2005 levels. The country faces both opportunities and obstacles in shifting to a grid powered by low-cost, variable renewable energy.

🇹🇼 How could a subset of commercial and industrial consumers using 24/7 carbon free energy help Taiwan achieve their emissions reduction goals? Our report will be released tomorrow. 🔎 Meanwhile, now is a great time to read our explainer on 24/7 CFE 👉 www.transitionzero.org/insights/wha...

🇲🇾 Malaysia intends to peak emissions around 2040 and reach net zero by 2050. With a rapidly industrialising economy and a grid powered largely by coal and gas, the move toward greater solar, storage and other renewables marks both a challenge and an opportunity for the clean energy transition. ☀️🔋

🇲🇾 Coming soon: our report on how 24/7 carbon free energy could help Malaysia (with its untapped renewable potential and improving regulatory landscape) strengthen its position as a regional energy transition leader. Meanwhile, check out our explainer 👉 www.transitionzero.org/insights/wha...

🚀 Scenario Builder now features multi-node models for Malaysia and the Philippines! We’re excited to expand Scenario Builder’s coverage to two of Southeast Asia’s most dynamic and fast-evolving power markets.

🇸🇬 Singapore has committed to reducing emissions to 45–50 MtCO₂e by 2035. 🏝️ As a small island city-state with limited domestic clean energy resources, Singapore requires careful planning to decarbonise its power system.

🇸🇬 Singapore has big emissions reductions goals. But with limited wind and solar resources and a current dependence on gas, this will require a major transformation of its power system. ⚡ We explored how 24/7 carbon free energy (CFE) could help. Stay tuned, the full report drops next week.
