Paragraph 4 Interpretation: generalF1

In this schedule—

• “cogeneration” means the simultaneous generation in one process of thermal energy and electrical or mechanical energy,

• “cogeneration unit” means a unit that is able to operate in cogeneration mode,

• “cost-benefit analysis” means a cost-benefit analysis carried out in accordance with paragraph 7 of this schedule,

• “economically justifiable demand” means a demand that does not exceed the needs for heating or cooling and which would otherwise be satisfied at market conditions by energy generation processes other than cogeneration,

• “electricity from cogeneration” means electricity generated in a process linked to the production of useful heat and calculated in accordance with the methodology in this schedule,

• “energy” means all forms of energy products, combustible fuels, heat, renewable energy, electricity, or any other form of energy,

• “energy savings” means an amount of saved energy determined by measuring and/or estimating consumption before and after implementation of an energy efficiency improvement measure, whilst ensuring normalisation for external conditions that affect energy consumption,

• “micro-cogeneration unit” means a cogeneration unit with a maximum capacity below 50 kW_e,

• “overall efficiency” means the annual sum of electricity and mechanical energy production and useful heat output divided by the fuel input used for heat produced in a cogeneration process and gross electricity and mechanical energy production,

• “power to heat ratio” means the ratio of electricity from cogeneration to useful heat when operating in full cogeneration mode using operational data of the specific unit,

• “refurbishment” does not include the fitting of equipment to capture carbon dioxide produced by a combustion installation for the purposes of geological storage,

• “small-scale cogeneration unit” means a cogeneration unit with installed capacity below 1 MW_,

• “unit” means any boilers, furnaces, turbines or compression ignition engines forming part of an installation which added together have a rated thermal input of more than 20 megawatts.
