The Government Energy Technology List

Energy Technology List

The Energy Technology List (ETL) is managed by the Depot for Business, Energy and Industrial Strategy (BEIS). The ETL includes energy saving technologies that qualify for Enhance Capital Allowances (ECA), whose purchase price can be claimed against tax relief 

The inclusion of UPS systems on the ECA scheme and ETL is designed to incentivise the adoption of the high efficiency uninterruptible power supplies. Uninterruptible power supplies eligible for inclusion on the list must meet certain threshold energy efficiency values. The ECA scheme includes static UPS that meet BS EN 62040-3:2011 (IEC 62040-3:2011) and covers the range 10-200kVA and from 200kVA upwards. The efficiency level thresholds include load ratings at 25%, 50%, 75% and 100% load.

UPS Size25%50%75%100%
>10kVA <= 200kVA>=94.0%>=95.5%>=95.5%>=95.5%

To apply for inclusion on the Energy Technology List, UPS manufacturers have to provide test results and documentation which may be audited by the ETL. Failure to pass audit can lead to UPS systems being delisted. Rotary UPS are also listed with their own set of energy performance thresholds from 100kVA upwards.

Further benefits from purchasing ETL qualifying energy efficient technologies can include: lower energy bills, reduced Climate Change Levy or CRC payment, and improved cash flow. To be included on the Energy Technology List a manufacturer has to submit their product data for examination against a number of load and operational related criteria. If a system is not included on the Energy Technology List it may have not been submitted or be going through assessment.
