What changes in equipment or operation did you make to reduce the peak demand?
The primary change was retiring 60 1000W fixtures in favour of 600 100W LED fixtures
Yeah, I meant 60 (typo fixed) and yes it saves us about $7000 per year on our hydro per year, almost entirely attributable to not paying delivery charge premium and not the piddling few cents per kWh charge. I am well aware that demand charges alone would never provide any payback. The ROI is about a decade but we are absolutely achieving the ROI. We did this several years back before LED profiles were a thing. That said, our primary motivator was not energy savings, it was to get colour mixing and not have to double and triple hang conventionals.

Sorry for the belated response. The lighting was temporarily in that configuration between quick activities. Normally they are aimed in more appropriate and interesting directions!
I'm late to the party here, but I'd also bring up the funding issue for fixture replacement. If the Powers That Be are approving conversion in drips and drabs, it makes sense to me to replace things behind the scenes first, then move onstage. If you've done the hallways and dressing rooms, but have the stage and house still left, you may be able to leverage funding that drys up when the highly visible changes have been made. Not that most folks would visually notice a good conversion, especially in non-dimmed applications. They'll sure notice a sloppy color temp change, though.
This has been my strategy on a gig that I PM every summer. I started by converting the exterior lights on the tent, as well as the work lights backstage and in concessions and ticket sales. This year I'm moving on to the house lights, and possibly starting the conversion over the stage. It's worked out well, because the funding hasn't dried up yet, though it does trickle instead of flow in. I'm still hoping for a donor that wants to "name" the new lighting rig.

You have a good base in the strand rack - because it has relay modules available for you to start distributing power for LED’s.
Choose a few circuits at ends and in middle of your plug strips, replace the existing dimmer modules with relays - change out the plugs on the strips to Edison so it’s clear they are supplied from the relays.
