Welcome to the Locational Value Maps (LVM) for Oahu, Maui and Hawaii Island
Locational Value Maps can help when planning customer-sited generation, also called Distributed Generation (DG). The maps provide an indication of the percentage of DG on the utilities’ distribution circuits.
DG may include:
•
Solar, wind, hydro or biomass renewable generation for Net Energy Metering (NEM), Feed-In Tariff (FIT) or a Standard Interconnection Agreement (SIA), or
•
Conventional generation for a Standard Interconnection Agreement (SIA).
IMPORTANT:
•
DG percentages on the LVM shown are based on installed systems and accepted interconnections.
•
LVMs are rough guides, updated regularly, but can quickly get out of date.
You may also ask your utility for a preliminary circuit check that may provide more up-to-date information. Please note this check does not reserve a place in line for your system nor does it guarantee that no further studies may be needed when you submit your application for utility review.
In almost all cases, small home or business systems (10kV or smaller single phase systems) will not require an interconnection requirements study.
For larger systems, an LVM address search or a preliminary circuit check from your utility does NOT guarantee that an interconnection requirements study will not be needed when you submit your application for utility review. If you are new to solar power and have questions, please contact the Solar Support Specialist at c-nmcint@heco.com (preferred) or by calling 808-543-4721 during business hours.
For customers with questions on solar power or contracts, please send email requests to:
Our goal is to help get as much customer-sited generation, especially renewable energy, as possible while maintaining reliable service to all customers. Reliable service may be impacted if a circuit has too much DG interconnected without proper protection equipment.
No limits are set on the amount of DG on a circuit. However, all interconnection applications go through an initial review process. Generally, if DG penetration on a circuit is less than 15% of peak load, your system may qualify for Simplified Interconnection. If penetration is 15% or greater, your application may need further review.
