AECL + RTAC Running Controls on Multiple POIs

Dan Sweeney's summary from meeting wit Attila, kyle, Pete, abd Keith:

Here is the link to the workbook for Jarrett that Keith worked with Attila to quote a single on site SCADA and controller for a multiple POI site.

In general, Engineering believes we can use this technique to reduce costs on a multiple POI site if:

• A 3555 or 3560 RTAC is specified
• Total POI capacity is below 50MVA
• Total number of control points doesn’t exceed the controller’s max guideline with additional headroom for multiple control loops running (50%?). This is limited to 100 devices (including relays, meters, etc) or 100,000 tags.
• Stem makes is very clear in the proposals that the site cannot share ownership now or in the future
• Should have a special review with engineering
• Unknown the effects of more than 4 separate sites above 10MW/each.
