The Clean Energy Investment Accelerator

Harnessing private sector demand to scale clean energy deployment in emerging markets


The Clean Energy Investment Accelerator (CEIA) brings together large commercial and industrial users to demonstrate innovative renewable energy purchasing models and strengthen policy frameworks.


The CEIA Model is built on three essential pillars for mobilizing clean energy investment at scale: Purchasers, Pipeline, and Policies.
