Lessons Learned from IG Pilots
Cross-cutting utility teams are needed in every step of the process for successful procurement and integrationNo procurement specifications exist for community scale PV
plantsConsistent application of existing standards enables more
seamless integration between manufacturers and utilitiesStandards for performance is critical to ensuring
technologies can be relied on in the field– Example: +/- 5% voltage accuracy with smart inverters is not enough
when using for grid support
DER communication and control is not yet utility-gradeUtility hands-on experience is vital to technology readiness
for the Integrated Grid
