Tracey Duffy, infrastructure delivery manager in the desktop services team at the bank, recounts how an IT initiative contributed to a corporate target to reduce electricity consumption by 20% by 2015.
The "power down PC" project started in the second quarter of 2012, and the organisation selected 1E as the supplier for its NightWatchman Enterprise system.
"Initial phases covered supplier selection, implementation of the infrastructure and client software and extensive business engagement," says Duffy. "The final stage was the roll-out of power policies, which ran from the third quarter of 2013 and completed in the first quarter of 2014, at which point the project closed, transferring the power management service into a business as usual process."
The project won a Computer Weekly enterprise software user award in June 2014. The organisation stated, in its entry, that in "eight months, the initiative delivered savings of £2,268,337 in electricity costs and 9,836,487kg of CO2, equating to 260,288 seedlings that have grown for 10 years or saving 1.1 million gallons of petrol".
Duffy describes how the project changed the culture at Lloyds: "Initially, our perception was that it wasn't possible to shut down desktops overnight, while maintaining our overnight deployment capability. However, we implemented a system which can intuitively wake desktops to receive deployments of software updates and security patches.

"Colleagues also queried if switching off desktops would add time to the start of the business day, or be an inconvenience if they needed to work outside of normal core business hours. To assess this, the project undertook significant business engagement to understand each business area's working patterns and implemented a power policy which minimised the risk of any disruption. The end result is that power management is an accepted part of the daily routine.
"Power management has been able to raise awareness that something as simple as switching off a desktop overnight can bring about a significant reduction in environmental impact. We have also seen a trend of people actively shutting down desktops at the end of the business day before the power policy takes effect."
The desktop services team is part of group IT and supports the Lloyds Banking Group desktop estate. Duffy led the project, the delivery of which was a collaboration between desktop services and systems management, which supported the NightWatchman application and its associated infrastructure.
The project brought together 91,000 employees, says Lloyds, "to work collectively to support the group's environmental statement, which states it 'works continually to reduce its environmental impact and facilitate a more sustainable, low-carbon, resource-efficient economy'".
