DG customers must know:
how long the steps in the process over which utility has control will take, &
what technical standards will be.
And those expectations must be reliably adhered to by utility.
Utilities, to reliably adhere to those expectations, must be given sufficient time & resources to process all applications.
Customers need to respond quickly to utility information needs to keep the process moving
Enforce timelines on both utility & customer sides,
which cannot be done without tracking performance against timelines;
Include more transparent technical standards with non-utility parties process for input
Have specific ways to deal with projects that are not moving forward, but holding a space in the interconnection queue
Implementation of strategies
Additional process changes
1) DTT and anti-islanding,
2) Limit of 3 MW/MVA on 13-15 kV feeders and related capacity limits,
4) External disconnect switches for small generators,
5) Interconnection practices in other states,
6) Witness testing protocols
Peak Load Threshold (Screen #2)
For “spot” networks, remove size screen (< 15 kW) for simplified process, if:
Extend the simplified network screen also to “area” networks, if:
Continue to monitor & track IEEE 1547 & national best practices, and incorporate IEEE guidance on networks into the new TSM Manual
Continue to study & experiment on Massachusetts area networks (e.g., NSTAR’s current Boston pilot project)
