Renewable Energy

As part of our carbon management programme we continue to review opportunities to reduce carbon dioxide (CO₂) emissions by switching to no or low-carbon energy sources.

67.5% of the 22,527 tonnes of CO₂ emissions reported for the common (landlord-controlled) areas of our portfolio in 2005- 2006 was from energy that was 100% supplied from Climate Change Levy (CCL) exempt sources. We continue to engage with our energy suppliers to increase the proportion of electricity supplied from CCL exempt sources to the common areas of our portfolio.

In 2006 we also commissioned a wind feasibility study in conjunction with the Carbon Trust. This ongoing study aims to identify opportunities to achieve CO₂ savings by switching electricity supply for common areas from fossil fuels to wind-generated power. This may also enable us to release CCL exempt renewable electricity back to the National Grid.

As part of the wind feasibility study we outlined factors that would indicate whether a property had poor or good capacity potential for wind-generated power. We then reviewed our managed property portfolio and produced a short list of potentially good sites. For each of these properties we are reviewing the technical, commercial and operational feasibility of installing a wind turbine on-site to provide electricity for the common areas as a minimum.

At Broadgate we also commissioned an energy feasibility study to identify opportunities to reduce CO₂ emissions, for example by installing tri-generation technologies. Tri-generation technologies reduce emissions by simultaneously producing three useful energies: heat, power and chilled water for air conditioning.
