Best practice project
| Information on reference projects available | yes |
|---|
| Best practice project - ongrid | Santa Rita Jail, – Located in San Francisco, USA. One of the most complex microgrids in the US consisting of 5 MW of wind, fuel cell, solar and diesel generation with one point of common coupling to Pacific Gas & Electric grid. Also, includes a dynamic load shedding system for the 1 million square foot campus, see attached slides for more details |
|---|
| Best practice project - offgrid | Xaranna Lodge, Botswana. Offgrid Microgrid consists of solar, battery and diesel generation. Objective of the project is to ensure power availability to he load while maximizing the PV as source of energy, thus minimizing diesel usage. The contorl system orchestrates the PV, BESS and diesel generators to best obtain project goals. System commissioing was in March 2017 |
