About Us

Investment Strategy

BIG is differentiated from other investors in the biomass and W2E sector by our long-term investment approach and our focus on mid-scale plants throughout the development cycle, from new greenfield sites to facilities already in operation.

We have achieved a leading position in the UK’s biomass and waste to energy sectors by establishing a portfolio of assets with the scale, diversification and operational synergies required to attract institutional investors such as pension funds and sovereign wealth funds.

Following a transaction with the Green Investment Group, formerly the UK Green Investment Bank, in August 2017, BIG added 20 assets to its portfolio. BIG is one of the largest investors in the sector with over 20 biomass and WtE facilities in the UK. Together BIG’s projects will provide enough renewable energy to power the equivalent of over 300,000 homes each year.

With over 100MW of operational and late-stage construction assets and a further 200MW in the pipeline, BIG is on course to make a significant contribution to the development of the UK’s low-carbon economy, by diverting over 1 million tonnes of waste from landfill and generating enough electricity for half a million homes.
