According to The British Pump Manufacturers’ Association (BPMA), the UK’s big businesses are paying for five power stations worth of electricity that they do not need each year. By reducing their annual energy consumption by just 1%, these companies could collectively save over £250m on their energy bills.
A considerable amount of the BPMA’s workload has been focused on the Energy Savings Opportunity Scheme (ESOS), which is the government’s way of implementing Art.8(4-6) of the Energy Efficiency Directive (EED),which came into force on 17 July 2014.
The EED establishes a common framework of measures for the promotion of energy efficiency within the EEU in order to ensure its 20% headline target on energy efficiency by the year 2020, and to pave the way for further energy-efficiency improvements.
This means we must use energy more efficiently at all stages of the energy chain – from the transformation of energy and its distribution to its final consumption. The EED will help remove barriers and overcome market failures that impede efficiency in the supply and use of energy and provides for the establishment of indicative national efficiency targets for 2020.
ESOS is a mandatory energy assessment and energy-saving identification scheme for large organisations – defined as those that employ at least 250 people or have an annual turnover of above £40m and a balance sheet of £34m – and their corporate groups, as well as charities and universities.
It is estimated that some 9,400 organisations will be affected. The public sector is currently excluded.
Comprehensive “energy audits” will form an integral part of the scheme and must be carried out every four years, with the first due by the date on which energy audits become mandatory: 5 December.
These audits have the potential to increase commercial profit-ability and competitiveness by identifying cost-effective savings that, if implemented, will improve energy efficiency.
It is estimated that ESOS will deliver £1.6bn in net benefits to the UK, with the majority of these being directly felt by businesses.
Given the amount of energy consumed by pumps through their normal operation, the BPMA has worked to develop a Certified Pump System Auditor Scheme (CPSA).
Through the CPSA, pump engineers are being trained to correctly assess the efficiency of pump systems and to provide recommendations in order to improve their efficiency.
The CPSA accreditation is achieved by successfully completing a four-day residential course, followed by the satisfactory completion of a pump system audit.
The objective is to help improve the levels of professionalism by creating a universally recognised and respected industry “standard” for those assessing a pumping system’s performance.
In the full ESOS guidance document, the ISO/14414-Pump System Energy Assessment standard is referenced as an auditing method that can be accepted by “lead assessors” approved by the Environment Agency. Accordingly, it is hoped that CPSA-accredited persons – who are trained according to the IS0 14414 standard – will be recommended by lead assessors to undertake the pumping system elements of company-wide energy audits.
