A notable project includes optimizing an 800 MW wind portfolio for Renovatio in Eastern Romania through customized measurement campaigns (source: 3e.eu). For Opdenergy in Spain, 3E provided regulatory and technical guidance for hybridizing existing installations with BESS and renewable energy (source: 3e.eu).

Recent Developments

In 2023, 3E achieved milestones of 20 GW of connected capacity in SynaptiQ and 90 GW of advised assets, and opened an office in Spain (source: 3e.eu).
