ABOUT

Green Rock Enterprises, LLC  (“Green Rock”) is an Energy & Infrastructure advisory and consulting boutique specializing in the South East Asia & Pacific Regions with offices and representatives in Indonesia and Singapore.

​

Green Rock was founded in 2015 by energy, infrastructure and financial industry veterans with technical engineers who have been successfully consulting, advising, raising capital and investing since the mid-1990s. Green Rock principals have a long history of successfully assisting clients with their strategic, technical evaluation and financing needs.  Additionally, Green Rock’s team have built-up over the years long-standing and extensive relationships with clients and other stakeholders in the Energy and Infrastructure sectors.

​

A challenge for larger mainstream financial institutions is building the expertise to assist viable, fundable, medium scale energy and infrastructure projects or companies, and matching them with investors and capital providers who have an appetite for small to medium size deals. These needs continue to dominate the energy space.

​

Green Rock’s expertise is targeted at filling this gap in the value chain by connecting capital with energy investment opportunities available today in South East Asia & Pacific Regions. Green Rock is able to assist clients in the analysis of opportunities, technical reviews, and corporate due diligence to develop appropriate financial or company structures, to complete mergers & acquisitions activities, and to raise debt or equity capital.

​

Built on the foundation of long standing relationships across the Energy industry spectrum, including Energy companies, capital raising and financial institutions, legal and insurance providers, and technical parties, Green Rock’s team is able to bring together a full complement of skills and know-how.
