According to Wired UK:
Today is set to be the start of a new era of cheap power, as a new type of low-cost nuclear reactor goes live in front of an audience of scientists and media representatives in Bologna. Once the mystery customer who commissioned the device has confirmed that it really is producing one megawatt, they’ll pay the developer, Andrea Rossi.
Unless, of course, it all goes horribly wrong. […]
And that’s the important thing about the 28 October test: for the first time it will be carried out by the customer’s consultants, not by Rossi himself. The customer, apparently a large US company which has declined to be identified, will be measuring for itself whether the E-Cat does what it says before it will pay for it. Rossi has claimed that the device will output six times as much energy as it consumes. If it fails to perform, Rossi will not get paid and the customer will doubtless remain anonymous to avoid the inevitable bad publicity. If it succeeds, the customer might reveal itself to take credit for financing the biggest breakthrough in energy production of the modern era.
You can find notes and video from the test here. The Pure Energy Systems Twitter account claims the same was made to the customer:
