Global sustainable funds are back. In the first quarter of 2026 they recorded estimated net inflows of US$ 3.5bn, reversing the US$ 27bn of outflows seen in the fourth quarter of 2025. Beyond the rebound, the findings of Morningstar’s Global Sustainable Fund Flows: Q1 2026 point to a turning point: the revival of European funds.
European sustainable funds returned to positive territory for the first time since the second quarter of 2024, with US$ 9.1bn in net inflows. Morningstar is not specific about our renewable energy market, but signals coming out of the US point to fresh interest in the sector.
There, standouts such as the First Trust Nasdaq Clean Edge Smart Grid Infrastructure fund, which gathered US$ 2.1bn, and the Invesco Solar ETF feature in the top 10 of sustainable flows. Morningstar reads especially the Smart Grid inflows as driven largely by the energy race to power AI systems.
That dry powder could convert into deals before long, so it is worth staying with Teaser Energy Europe to follow how this momentum develops.
Our highlighted deals this week are:
- Kyivstar acquires six Lviv-region solar plants totalling 105 MW for US$ 808m, lifting its solar capacity to 118 MW and adding generation equivalent to around 30% of its annual telecom electricity consumption.
- Sumitomo enters Gresham House‘s 694 MW BESS platform via Summit Transition Partners, taking initial exposure to 397 MW of near-term projects and securing exclusivity over a further 297 MW in GB grid-scale storage.
- Gresham House also moved on a conditional SPA to acquire the 480 MW, minimum 960 MWh Rayleigh BESS project in Essex, expanding its new-build pipeline to 1.17 GW and adding a storage asset nearly five times larger than its current biggest operational battery. Busy week for its dealmakers.
