The product, dubbed SSE Green, intends to support large industrial and commercial operations in the UK to manage greenhouse gas emissions (GHG).

The company will deliver renewable energy equal to Renewable Energy Guarantee of Origins (REGOs). This certifies that the purchased electricity has been guaranteed exclusively viaa portfolio of wind and hydro assets.

From October 2013, it is mandatory for Financial Times Stock Exchange (FTSE) 100 companies to unveil their GHG emissions report in their annual reports.

SSE said the latest amendment to the GHG Protocol Corporate Standard, Scope 2 Guidance was introduced in January 2015 and made changes to the way in which organizations should report their GHG emissions.

SSE Green does not take into account biomass and only includes REGOs from wind and hydro assets.

SSE business energy director Terry Tippell said: "We are delighted to offer this new contract to business customers which allows them to demonstrate their commitment to renewable and sustainable goals, as well as enhancing their environmental reputation and commitment to customers and other stakeholders.

"Equally, large organisations can benefit greatly by being able to report zero emissions for their purchased electricity."

SSE has invested more than £4bn in renewable energy sources since April 2007. and has over 2500MW of operating wind and hydro assets. A further 400MW of onshore wind projects are under construction.
