1) Silicon Energy was never publicly traded. It was acquired by the largest advanced metering and energy intelligence business; Itron. Itron is publicly traded: ITRI. The fact that it was acquired explains the “surrendered” status of the original corporation.

2) Northern Power was also an acquisition by Proton Energy Systems (later named Distributed Energy Systems). Proton itself was an early investment of Nth Power’s and was an IPO.

3) You missed a few other important deals we’ve backed:
a) We IPO’d and led a PIPE investment in Evergreen Solar, the first pure play solar stock;
b) We IPO’d Capstone Turbine, the first pure play microturbine stock and early leader in distributed generation; and,
c) We sold Nanogram Devices, a novel battery for medical devices to the worlds largest supplier of power systems to the medical device industry, Wilson Greatbatch.

Just wanted to set the record straight and expand on some of the information in your post.
