My company has worked on a lot of Department of Energy #SolarPower research projects in the past via the "Sunshot" grant program.
This year there were 3 research funding opportunities related to our work, so we spent a lot of time crafting proposals for each one. The DOE abruptly canceled the opportunities *after* everybody submitted proposals. Big waste of our time. Never seen anything so unprofessional from the DOE before.
