Both the 250 kVA and 300 kVA versions of the NXE now feature on the exclusive list after meeting the scheme’s strict energy efficiency thresholds across a series of load levels.
This means customers can claim back the cost of buying and installing the super-efficient NXE against their company’s profits (Corporation or Income Tax), making them an even better value for money option.
Manufactured with the latest transformerless technology, the three-phase NXE offers exceptional efficiency up to 97% in standard double conversion online mode, which can be increased to 99% in ECO operating mode.
The NextEnergy range, which has recently been expanded with a higher power 400 kVA model, also incorporates an innovative Efficiency Control System that minimises waste even at partial loads.
It joins other Riello UPS products that have already secured a spot on the list – the Multi Power (MPW) modular systems (both standard and combo cabinets) and the 30, 40, 125, and 200 kVA versions of the versatile and smart grid-ready Multi Sentry (MST).
What Is The Energy Technology List?
The ETL is part of the wider Enhanced Capital Allowance (ECAs) tax scheme, which enables companies to offset 100% of the cost of buying new equipment against their taxable profits. That’s more than five times the rate of standard tax relief on equipment purchases.
It aims to encourage businesses to take a long-term approach to their infrastructure by investing in ‘best in class’ technologies that reduce power consumption and carbon emissions.
The tax relief helps mitigate any higher initial purchase costs to persuade firms to buy quality, efficient products rather than cheaper, energy-intensive equipment. Companies benefit in the long-run from lower energy bills and greater control over the Total Cost of Ownership, while it can also help them meet stringent environmental legislation and regulations.
Around 17,000 products currently feature on the directory, ranging from boilers, lighting, and refrigerators, to hand dryers and heating, ventilation and air conditioning (HVAC) equipment.
Uninterruptible power supplies are also on the list to incentivise data centre operators, IT directors, and facilities managers to upgrade to the most efficient power protection equipment.
To be eligible for the ETL scheme, a UPS must meet strict energy efficiency thresholds at load ratings of 25%, 50%, 75% and 100%. Manufacturers must submit product data and test results for rigorous independent evaluation and auditing in order to qualify.
ETL Minimum Efficiency Thresholds For UPS
| Product | Power Range (kVA) | 25% load | 50% load | 75% load | 100% load |
| Static UPS | >=10 | >=94.0 | >=95.5 | >=95.5 | >=95.5 |
| Rotary UPS | >=200 | >=91.0 | >=95.0 | >=95.5 | >=96.0 |
The ETL efficiency threshold has been updated recently to reflect the continued advances in UPS technology, such as the development of transformerless-based systems.
Analysis suggests that newer, more efficient types of UPS such as those featured on the ETL deliver energy savings of 4% compared to the market average.
