My Lords, the energy efficiency directive updates the EU’s legal framework for energy efficiency, with a target of saving 20% of the EU’s primary energy consumption by 2020 and of making further energy efficiency improvements after that date. The directive establishes a common framework of measures for the promotion of energy efficiency within the EU
and lays down rules to remove barriers in the energy market and overcome market failures that impede efficiency.
My department has responsibility for the aspects relating to increasing the uptake of cost-beneficial cogeneration, usually known as combined heat and power, and waste heat recovery systems in the UK. The Environmental Permitting (England and Wales) (Amendment) Regulations 2015 that we are debating today transpose in England and Wales Articles 14.5 to 14.9 of the energy efficiency directive.
The amending regulations require operators of new or substantially refurbished combustion installations of more than 20 megawatts in size to carry out a cost-benefit analysis and therefore consider whether the installation of combined heat and power, or waste heat recovery systems and the use of waste heat, could be cost-beneficial, with the aim of increasing energy efficiency.
Where cogeneration or waste heat recovery and use options are shown to be cost-beneficial, operators will have to install such systems, and this will be a requirement of their environmental permit. By installing such systems, operators will achieve cost savings. There will also be social benefits from reduced carbon emissions and improved security of energy supply. The amending regulations are consistent with our aim of protecting the environment for future generations, making our economy more environmentally sustainable and improving our quality of life and well-being.
The choice to transpose the requirement for a cost-benefit analysis by amending the existing environmental permitting regime has clear benefits for operators and regulators alike. Environmental permitting is an established process for regulating the development, operation and refurbishment of industrial installations in England and Wales. Nearly all the installations subject to the requirements of Article 14(5) of the directive are already subject to the Environmental Permitting (England and Wales) Regulations 2010, as amended. Use of this existing system therefore allows implementation of the requirements of these articles in a manner which limits burdens on operators and regulators.
My department conducted a public consultation exercise between February and April 2014. There were 20 responses to the consultation. All supported the use of the Environmental Permitting (England and Wales) Regulations to transpose the requirements of the directive. A number of concerns were raised by respondents regarding the suitability and practicality of the thresholds applied in the instrument. These concerns have been taken on board and changes have been made to the regulations to reflect this.
An impact assessment was prepared for the implementation of these amending regulations which showed an estimated net cost of £12.4 million over the 10-year appraisal period. The costs to regulators are included in this figure and may be recouped through environmental permitting fees and charges.
There will clearly be benefits to improving energy efficiency for both the operator and society. The impact assessment was not able to quantify these benefits overall as it is unclear how many operators would introduce changes. However, the impact assessment
included a number of case studies which, for example, suggest that if combined heat and power were installed instead of an industrial boiler, depending on the size and configuration of the boiler, the operator could see annual savings of between £1 million and £7 million, paying back their upfront investment within six years.
These amending regulations will help to ensure that operators install energy efficient systems and reduce the carbon emissions where they are cost beneficial. I therefore commend the regulations to the Committee.
