Carbon Metrics Limited was formed in 2016 by Fintan Whelan and Doug Farrell in response to the demand for innovative funding solutions in the renewable energy sector. Having identified a significant disconnect between energy service companies and institutional funding models, Carbon Metrics acts as a bridge to gain access to these funds in a cost-efficient manner. This bridge in effect gives the institutional funders the scale they require whilst simultaneously giving smaller projects access to a market not previously open to them.

Fintan has been active in Renewables since joining the newly-formed Airtricity in 2000 as Corporate Finance Manager. In 2008, he co-founded Mainstream Renewable Power, along with ex Airtricity CEO Eddie O’Connor, focusing on development of SolarPV & onshore/offshore wind projects across a number of markets – US, Canada, Chile, South Africa, Ireland, UK and Germany.

He left Mainstream in 2014 to focus on the emerging opportunities for Corporates as technology and economics evolve, subsidies for large scale renewables fall away and the business model of utilities becomes increasingly challenged by these forces.

At Carbon Metrics, Fintan is deploying his knowledge of funding mechanisms & providers to source the best shaped funding solutions for the needs of Energy Consultants and their clients for their investment in business infrastructure and sustainable profitability.

Fintan is actively involved across the sector –

  • He works with Amarenco on the expansion of their European business into wind and innovative routes to market for electricity.
  • Emerging Markets Power ltd – Fintan is a Co-Founder & Director of this greenfield wind developer, currently working on Utility scale projects in Ghana and Tanzania. This is a Joint Venture with Vestas and is backed by Belltown Power.
  • Fintan is a Non-Executive director of SolarPV specialist developer BNRG Renewables.
  • He is a regular speaker at Industry Conferences.

Doug has considerable experience within the real estate, finance and renewable energy sectors since 2003.

He co-founded the real estate company Caelum Development in 2003 in Poland, which grew to become one of Ireland’s largest private commercial portfolios operating in the country. The group also operated in Germany, Hungary and Romania.

In 2007, whilst still at Caelum, Doug was the founding shareholder of Power21 and Propower, two regulated energy companies operating in the Polish market. The principal activities were energy distribution and transmission respectively and gave Doug a good perspective of how large retail clients operate in terms of energy management. As management board member of both companies Doug has a good understanding of how utilities operate and how their clients react to those operations in the commercial market.

Spending more time in Ireland since 2014, Doug became actively involved in the Solar PV industry advising corporate clients on the potential to generate on site electricity. The single most important take away from these interactions was that there is no single answer to either efficiency or generation and that multi technology solutions work best. This has been borne out through his interactions with engineering and energy service companies who see the importance of having a funding facility that supports and matches the successive aspects of the technologies – a multi-stage incremental program as technology and economics evolve.
