Offsite Renewables contributing to the energy model

Hi, Curious if there are any updates or lessons learned on this? My interpretation is that through the v4.1 approach,  on-site can now be used to contribute to the pre-requisite, and off-site can now contribute to the points (not to the pre-req theshold) but not seen many projects pursure yet. 

Thanks! 

From the BD+C Guide: 

Renewable Energy in the Energy Model
 Energy costs and greenhouse gas emissions offset by on-site or on-campus renewable energy systems count towards energy savings for compliance with the prerequisite when these systems are included on the building permit or on a master site permit including the building for a contiguous campus consistent with ASHRAE Standard 90.1-2016 Section G2.4.1 requirements, and associated environmental attributes are retained by the building owner. ASHRAE 90.1-2016 defines on-site renewable energy as “energy generated from renewable sources produced at the building site”, which includes on-site photovoltaics systems, wind generators, or thermal or electric generation from methane capture or qualifying biofuel sourced from the project or campus site, but does not include electric generation or thermal generation from off-site renewable sources.
 Greenhouse gas emissions offset by Tier 2 off-site renewable energy systems qualifying under EA credit Renewable Energy may be included in the model for achievement of points using the greenhouse gas emissions calculation under EA credit Optimize Energy Performance, but may not be included in the model for prerequisite compliance. Modeled building GHG emissions and avoided GHG emissions from Tier 2 off-site renewable energy can be modeled using the hourly generation profile from the project’s grid region and the renewable generation grid region in locations where hourly emissions factors are available.
