The United Kingdom's Four Rivers BioEnergy, Inc. has recently been certified as "100% Biomass" by energy state regulator Office of Gas and Electricity Markets (Ofgem) and is now entitled to receive renewable obligation certificates.

In a letter issued to shareholders, Four Rivers chief executive Stephen Padgett said the company, which is developing a waste-to-energy plant in North east England under the trade name Verta Energy and is planning to start business in the United States and other European states, has acquired its new status.

R.O.C.'s are green certificates issued by Ofgem to operators of accredited renewable generating stations for the eligible renewable electricity they generate. These R.O.C.'s can be sold to other parties, and are used by suppliers to demonstrate that they have met their renewable electricity obligation.

In the case that suppliers are unable to meet their renewable energy obligation, they must pay an equivalent amount in a "buy-out" fund. – (Jhoanna Frances S. Valdez)
