Marriott International

Industrial & Commercial DSR, UK


Marriott is one of the world’s leading hotel chains, operating over 7,000 properties across 130 countries and territories globally.

As part of its Serve 360 Doing Good In Every Direction sustainability and social impact strategy Marriott has ambitious goals to build, fit-out and manage Marriott properties sustainably and include targets to reduce carbon intensity by 30% as well as achieving a minimum of 30% renewable electricity use by 2025.

Kiwi Power has been working with Marriott since 2012 to help it use Demand Side Response (DSR) to improve its energy efficiency, relieve stress on the grid and generate additional revenues for future sustainability projects.

We have focused on large pieces of electrical equipment such as the chillers that are used for air conditioning and refrigeration. Turning these down for short periods of time within agreed parameters can be done with little or no effect on Marriott’s operations, and there’s been no adverse reaction from guests.

We are working together at ten of the chain’s hotels across the UK. Small reductions in demand at individual hotels can be aggregated into a significant overall reduction. Kiwi Power uses this aggregated capacity to help National Grid balance electricity supply and demand across the UK at times of high demand or when additional flexibility is called for.

Marriott receives a payment for being available for DSR and again whenever they are asked to turn down equipment. At the same time their participation demonstrates their commitment to sustainable energy use and enables them to play an active role in helping to create the smarter, more flexible energy system we need to integrate renewable generation at scale.

Marriott’s guests rightly expect us to be doing everything we can to protect the environment and Demand Side Response is an important part of that –but it also makes commercial sense. We’re very proud to have been the first UK hotel company to embrace Demand Side Response and we want to expand our work with Kiwi Power to make sure we maximise the benefits.
