METERING & MONITORING

Streamlined energy reporting for energy optimisation
The government launched its Streamlined Energy and Carbon Reporng policy in April. Its purpose is to encourage large businesses to become more energy ecient by reporng energy use and GHG emissions. Will Darby, managing director of controls and automaon specialist Carlo Gavazzi UK, explains how the installaon of energy meters and a monitoring system can help businesses opmise energy usage and simplify their annual reporng requirement
The SECR replaces the Carbon Reduction Commitment (CRC) Energy Efficiency Scheme for large quoted companies. However, in addition to the large quoted companies that were the focus of the CRC, the new scheme has been extended to include large unquoted companies and limited liability partnerships (LLPs) in an effort to encourage more businesses to implement energy efficiency measures. The government estimates that following the SECR's introduction 11,900 UK businesses will now need to disclose their energy and carbon emissions from 1 April 2019.

The extension of the scheme means that charities, not-for- profit companies and organisations undertaking public activities, such as companies owned by universities or NHS Trusts, may now fall under the expanded qualifying criteria. In addition, private sector organisations which fall outside of the scope of the new regulations are encouraged to voluntarily report in a similar manner.
Companies that use less than 40MWh of energy in a year will generally be exempt from reporting.
It is worth noting that all businesses that come under the SECR will need to report energy use and GHG emissions along with a description of measures taken to improve energy efficiency over the reporting year. The government expects companies to be more likely to take action on climate-related risks if more information is in the public domain. In addition, the information gathered from the SECR will enable policy makers and analysts to build a clearer picture of carbon emissions and energy usage across businesses, creating a more realistic picture of the real climate change risks within the UK. And, having more inclusive and transparent disclosures will allow investors to benchmark businesses based on their emissions in order to take investment decisions.
In order to report their energy use, businesses need to meter energy use, and in order to improve energy efficiency, businesses need to analyse energy use. The old adage - you cannot manage what you don’t measure - is certainly true when it comes to compliance with the SECR. The simple function of installing metering on all of a company's primary energy-consuming plant will provide a huge amount of useful reporting data. And, once collected, the data can be used to optimise the way a facility is run to help save energy. Meters such as Carlo Gavazzi’s EM330 and EM340 3-phase energy analyser are perfectly suited to both active and reactive energy metering of individual items of machinery with a high power consumption, particularly for applications such as manufacturing plants.
In addition, single phase applications such as HVAC equipment, lighting circuits, computer servers and other power-consuming auxiliary equipment can all be monitored using 1-phase energy analysers, such as Carlo Gavazzi’s EM111 and EM112 units.
To monitor the system, record and transmit data, the energy analysers can be connected to Carlo Gavazzi’s UWP universal web platform. This is a micro-PC which is pre- installed with a customisable web server. This smart energy monitoring solution makes it a simple task to determine energy usage of both individual items of equipment and a facility’s overall energy usage, either in the facility or remotely, to see how much power is being used, where and when, both as real time consumption and as historical data. In addition to reporting, using these simple metering and monitoring tools will enable a manufacturing business to analyse and trend electricity usage and to proactively and predictively manage electricity use in a single facility or even across multiple sites.
Having detailed power consumption data, for example, will also help managers realise savings by making it easier to see when and where power is being consumed. It may even provide sufficient information for large power consuming businesses to consider shifting the timing of power intensive operations to take advantage of cheaper electricity tariffs; or to consider off-grid options, such as battery back-up or running stand-by generators.
Of course, energy consuming systems evolve over time as equipment is added or replaced or building usage or manufacturing processes change. Metering and monitoring should not be seen as a ‘nice to have’ but as a fundamental tool in enabling a facility to be running efficiently. By continuously and actively monitoring energy consumption a manager will be able to ensure that systems are working efficiently and effectively to help deliver benefits to the bottom line.

he UK government’s Streamlined Energy and Carbon Reporting (SECR) policy came into force in April. It was introduced because the government wants large businesses to become more energy efficient in order to reduce their carbon emissions.
