Great job! I will recommend acceptance of this proposal by the HC. There's only one issue to be addressed:
The proposed IEEE plaque and the Milestone site are separated. Please consider adding words stating that the Milestone is actually away from the lobby at .... such and such. Currently the citation has 69 words. Take a look at the way other milestones have dealt with this. Or consider installing an additional dummy plaque at the site.
Attempt No. 5
Thank you, dear Gill Cooke, for being our Advocate and for your comments!
Below, please find our revised text proposal for the plaque.
"Built by SIEMENS and operated by Western Area Power Administration (US DOE) since 1987, the 200 MW HVDC Virginia Smith Converter Station (SCS) located near Sidney, Nebraska, connects the eastern and western US grids. The SCS core technology is an all solid state converter with integrated steady state, dynamic and transient voltage control up to its full rating. The SCS represents an important advance in HVDC technology and cost effectiveness."
