Global energy think tank accelerating the clean energy transition with data and policy #CleanPower info@ember-energy.org
@ember-energy.orgWatch our explainer on how batteries added this year could shift over a third of new solar generation daily 🎥

@ember-energy.org@ember-energy.orgAs solar meets a growing share of global electricity, batteries are key to shifting clean power to non-sunny hours ☀️
Catch-up with Ember's Kostantsa Rangelova at the World Energy Storage Conference to learn how batteries can accelerate solar growth.
@ember-energy.org🗣 "Tailored interventions to the asset class and market would be the most effective way to close the bankability gap in ASEAN's renewable and grid projects," emphasises Ember's Dr Dinita Setyawati.
Clear offtake and storage revenue streams are vital ⚡
@ember-energy.orgEmber assessed the storage market readiness across Southeast Asian countries. The index scores found a divergence:
🇵🇭🇸🇬 ~80%
🇮🇩🇻🇳 ~50%
🇲🇾 35%
A dedicated capacity market in the region would enable battery storage bankability.
@ember-energy.org#ASEAN's announced storage projects total just 7 GW – less than a THIRD of required capacity (23-26 GW) 🔋
Without dedicated capacity markets and revenue stacking, battery deployment will lag behind regional renewable targets.
@ember-energy.orgCheaper borrowing alone cannot enable distributed solar to scale in Southeast Asia – as project size determines bankability ☀️
Closing the bankability gap requires portfolio aggregation, standardised contracts, and revenue enhancements.
@ember-energy.orgThe bottom line: 🏭 Importing fossil fuels = paying volatile prices every year to generate power ☀️ Investing in renewables = paying once to generate for decades
@ember-energy.orgBut a system built on renewables is far more resilient to disruptions – making it a key component in achieving energy sovereignty. 4/5
@ember-energy.orgDependency on imported fossil fuels is a risky choice for countries. The recurring expense leaves them exposed to global price shocks, which can trigger inflation and higher household bills. 3/5
@ember-energy.orgAnd in Great Exuma, the Bahamas, the state utility contracted 3 MW of solar at less than HALF the price of gas per kilowatt-hour 🇧🇸 Policy – not cost – is delaying the Caribbean’s shift from imported fossil fuels to clean, homegrown power. 2/5
@ember-energy.orgRenewables are already cheaper than fossil power, and the Caribbean has two case studies to prove it This year the Dominican Republic, host of OLACDE Energy Week 2026, awarded 326 MW of renewables + batteries at 28% cheaper than the average cost of electricity generation in 2025 🧵 1/5
@ember-energy.orgThe distributed solar power boom in Pakistan and the Philippines is driving down the need for fossil-powered electricity.
Solar is "gradually reducing the market share and operating hours of fossil fuel plants” says Ember's Alnie Demoral via Bloomberg.
@ember-energy.org🚨 NEW | The bottleneck to scaling clean energy in Southeast Asia has shifted from raising capital to creating bankable projects ⚡
Utility-scale solar attracts commercial finance at competitive tariffs – but distributed solar, storage and grids face major financing gaps.
@ember-energy.orgOnly 10% of global hard coal production has ever had a methane plume attributed to it. Japan’s 2nd-largest coal supplier, Indonesia, has almost none.
Without clear disclosure, Japan’s steelmakers could miss the full extent of methane their coal carries.
@ember-energy.orgEn “La era del poder”, sostenemos que la revolución electrotecnológica y la digital están profundamente entrelazadas: las renovables han abaratado los electrones, la digitalización y la IA los han vuelto inteligentes, y las baterías los han hecho móviles.
@ember-energy.orgIn "The Age of Power", we argue that the electrotech and digital revolutions are deeply intertwined: renewables have made electrons cheap, digitalisation and AI have made them smart, and batteries have made them mobile.
@ember-energy.orgThe good news? 🇮🇩's government is currently developing Tier-2 emission factors and emissions reporting guidelines for companies. But the key challenge still remains: how do we translate this data into accountability? Learn more ⬇️
@ember-energy.orgEmber’s previous research also revealed that only five Indonesian coal companies included coal mine methane emissions in their sustainability reports – a major risk for buyers that initiatives like CLEAN could help address 🚩
@ember-energy.orgIndonesia’s measurement of coal mine methane is rated at just 1 out of 6 by Ember due to default emissions factors being used and significant reporting gaps making official figures 6-14x lower than international estimates such as @GlobalEnergyMon and @IEA 📊
@ember-energy.orgTracking emissions from imported energy is crucial for Japan – in 2023, Japan launched the CLEAN initiative to promote methane disclosure in the oil and gas sector. This framework should now be expanded to also cover coal imports ⏩
