Construction Service Guidelines
New Construction/Change of Service
For all new construction or existing construction in the YVEA system please call Emma Mortenson at 970-871-2242.
For existing construction in the YVEA system please have your service order number available.
All new construction requires the following documentation prior to a field service representative being assigned to an applicants project:
Additional documentation that may be required for your application:
Electric Service Requirements Manual:
YVEA's Electric Service Requirement Manual provides applicants, electricians and existing members with a guide to the expectations for new construction, temporary service and change of service in YVEA territory. The document should be referenced prior to submitting the New Construction/Change of Service Form.
YVEA provides a Maximum Available Fault Current Table that satisfies the requirements of the 2017 NEC, Section 110.24. Please reference this table for all engineering design requirements. This table uses the “Infinite Bus” method for calculations with impedances determined by the mean value of YVEA equipment in inventory. These values may be used to determine a conservative AIC rating for service equipment. YVEA does not recommend or condone using this value for any other electrical purpose, including arc flash analysis. Injury to personnel, including death, and damage to equipment may result. The data is for standard back configurations only, non-standard configuration fault data may be requested through YVEA Engineering.
Arc Flash Analysis:
Members may request fault current data to be used for arc flash analysis from YVEA Engineering, which may be subject to an Engineering fee. Analysis required a fault current study to be performed by YVEA Engineering. The data provided from this request is only valid for the system that existed at the time of analysis and during normal system conditions. The user acknowledges, by acceptance of the data, that the data may change depending on system condition, future construction and changes to the members service. YVEA does not assume any responsibility for events resulting from the use of this data by the member or any agent of the member.
Distributed Generation Interconnection:
New and existing installations that will be installing Renewable Energy and/or parallel net metered generators require additional documentation to be submitted to YVEA. Please see the YVEA Renewable Energy Interconnection web page for documents required.
Standby Generator Interconnection:
YVEA has a new Standby Generator Program which can be found at:
If a member wishes to install their own stand-by generator a permit must be acquired from the county. All installations must meet NEC Article 705 and additional YVEA requirements including the installation of a UL Listed break-before-make automatic transfer switch. An additional service entrance disconnect that is visible, accessible and lockable is recommended. The member must provide YVEA with a copy of the electrical permit and inspection and must notify YVEA of the generator size for our records.
Joint Use Applications:
All new requests for joint use attachments require a Joint Use Application to be submitted and the appropriate fee paid prior to any work being performed on the project. If the joint use customer does not have a YVEA Joint Use License Agreement then they must request an agreement from YVEA Engineering. The schedule of fee’s for joint use can be found below:
