Building trust and bridging the gap to commercial scale
The case for LDES is clear. The next challenge is delivery.
- Rising electricity demand, renewable growth, and the need for reliable clean power are creating a stronger case for LDES.
- Scaling it will require clear use cases, customer confidence, investable projects, and the right market conditions.
- The 2026 Annual Member Meeting will bring LDES Council members face to face with the organisations asking what is ready, what is bankable, and where LDES can meet real needs today.
