The satellite has a mass of 3,460 kilograms, and a planned service life of 15 years. On 28 January 2009, Eutelsat announced that it would not accept delivery of the satellite due to what was described as a "major anomaly affecting the satellite's power subsystem".
Commenting on these decisions, Eutelsat Communications Chairman and CEO Giuliano Berretta said: "The situation affecting W2M is a serious disappointment for Eutelsat. However, for many years we have pursued a strategy based on securing and expanding our in-orbit resources in order to mitigate this type of risk. Our current investment programme consequently combines early renewal of operating satellites, together with securing the fleet through readily available back-up resources, and expansion of services with larger satellites. This policy puts us in a position to absorb the unavailability of W2M without impact on the continuity of service we provide our customers."
On the same day Eutelsat also confirmed that the unavailability of W2M does not impact on the Group’s guidance for revenues in excess of 900 million euros for the 2008-2009 financial year since the W2M satellite programme is fully insured.
Although Eutelsat had originally declared that, due to the power system partial failure, W2M would not be integrated into Eutelsat’s satellite fleet; after the in-orbit failure of Eutelsat W2 in January 2010, Eutelsat decided to redeploy W2M at 16°E to provide limited back-up services for the failed W2 satellite.
