This is not to say that the US market has stalled: ReliOn, IdaTech and Altergy all found an early market there and, while expanding their global reach, continue to supply systems for domestic customers who reap the benefi ts of reliable power. Altergy in particular has recently announced some very large US orders, including a total of 22 MW of its 10 kW and 15 kW Freedom Power fuel cell systems for mobile phone company MetroPCS for which deployments are underway. According to Altergy, MetroPCS tested batteries, generators and fuel cells and found fuel cells to be more convenient, more.
