About CEIG


Investing for Australia's Clean Energy Future

About Clean Energy Investor Group 

The Clean Energy Investor Group (CEIG) was formed in July 2019 by a group of institutional investors in utility-scale renewable energy projects. The Group was originally a sole-purpose advocacy group engaging with market stakeholders on the increasing volatility and risks being experienced by investors arising from ‘Marginal (transmission) Loss Factors’ in the National Electricity Market (NEM).

The CEIG has since extended its advocacy, education, and stakeholder engagement across a number of other areas continuing to impact institutional investors in utility-scale renewable energy projects.

The CEIG represents institutional investors who have funded Australian renewable energy projects worth over AUD$9billion. Collectively the Group currently expects to deliver over 6GW of Australian renewable energy projects in the near future. Our members include superannuation/ pension funds, infrastructure fund managers, project developers, and Independent Power Producers.

The importance of the CEIG

The CEIG's membership base represents the most prevalent category of investor in the global renewable energy market – institutional investors.

Institutional investors represent the largest pools of global capital, ready to deliver the megawatt capacity needed to secure Australia’s required future electricity supply. Their investment hurdles are the lowest globally, ultimately leading to lower wholesale power prices in the NEM.

Institutional investors bring competition to the NEM “gentailer” oligopoly (for the first time since vertical integration re-commenced in the 2000s), ultimately leading to lower wholesale power prices in the NEM.

We use our unique "voice of capital" for coordinated and targeted advocacy and market engagement in the best interests of
institutional investors.

Advocacy and initiatives

The Australian National Electricity Market is and will continue to rapidly decarbonise, needing to transition to a more technology-flexible power system. With rapid change can come new risks and costs which need to be allocated to those best able to manage them.


On behalf of our members we develop and execute targeted stakeholder consultation and advocacy programs to engage with:

  • Federal and State Energy Ministers and energy departments;

  • The Australian Energy Markets Commission Commissioners & staff;

  • The Australian Energy Market Operator management & staff;

  • The Australian Energy Regulator & staff;

  • The Energy Security Board;

  • Industry Associations; and

  • Media


Across regulation and policy arenas we initiate, investigate, and respond to consultations and national electricity rule changes that impact institutional investors.
