System Offset Notes

Interconnecting Customers using Listed single-phase inverter-based Facilities with power ratings of 10 kW or less receiving single-phase service from a single-phase transformer, or using Listed three-phase inverter-based Facilities with power ratings 25 kW or less receiving three-phase service from a three-phase transformer configuration, and requesting an interconnection on a radial feeder where the aggregate Facility capacity on the circuit is less than 7.5% of the circuit annual peak load qualify for Simplified interconnection

SLD Reqs

Relay Meter Orientation = Over/Under

• A separate single direction meter that measures all generation produced by the Facility will be installed.
• 5 terminal PV meter required. Must be indicated as 5 jaw on plans. Wired top toward AC disconnect, bottom toward POI.
• Name the PV meter "Utility Production Meter". This utility does not participate in the SMART program, do not label the meter as SMART.

Electric Service Reqs

Transient Voltage Conditions

Because of unusual events on the HG&E EDS, there will be

transient voltage fluctuations that will result in voltages exceeding the limits of the stated ranges.

The Facility must be designed to handle these transient conditions.

Noise and Harmonics

Noise and harmonics levels shall not exceed those allowed in the most

current IEEE Standard 1547. 

Frequency

The HG&E EDS generally operates at 60 hertz. Instantaneous deviations from 60 hertz occur infrequently and may be as much as +/- two tenths of a cycle. The Facility should be designed to handle these transient conditions.

Machine Reactive Capability

Facilities < 1 megawatt (“MW”) will not be required to provide reactive capability. Facilities > 1 MW may be required to provide reactive capability to regulate and maintain distribution system voltage within an acceptable range.

Protection Requirements

In addition to any further HG&E requirements as part of the application process, any Facility to be interconnected with the HG&E distribution system must comply with the standards listed below.

• IEEE Standard 1547, Latest.
• UL Standard 1741.
• IEEE Standard 929-2000 

Supply Characteristics:

a. In general, only single-phase service will be supplied to residential loads.

b. The maximum single-phase service from an overhead distribution system is 400 amps, including the total rated capacity for multiple main switches. Under some circumstances, a 400 amp main disconnect is required ahead of the multiple sub-main switches whose total rated ampacity exceeds 400 amps (excluding the owners loop if it is rated at 60 amps). Please consult with a HG&E Engineer for all services over 400 amps.

c. Single-phase services over 400 amps and up to 800 amps maximum must be fed from a padmount transformer. The largestsingle-phase service allowed is 800 amps. Please consult with an HG&E Engineer for all services over 800 amps. HG&E does not provide instrument transformer rated single phase metering, therefore, load greater than 400 amps and up to 800 amps would require multiple self-contained meters or a three phase service feeding multiple single phase services.

Install Reqs

General

1. The Interconnecting Customer shall furnish, install and maintain all meter mounting equipment such as or including meter sockets, test switches, conduits and enclosures
2. It is the responsibility of the Interconnecting Customer to design, procure, install, operate and maintain all necessary equipment on its property for connection to HG&E’s EDS in accordance with Good Utility Practice

Production Meter

1. A separate single direction meter that measures all generation produced by the Facility will be installed

AC Disconnect

1. The HG&E shall have access to the disconnect switch of the Facility at all times.

Line Side Tap

1. Line-side conductors are always connected to the top terminals of meter sockets and the load-side conductors to the bottom terminals. Standard connections for single-phase and three-wire network socket meter installations are shown in Figure 17, page 67. (See attachment: Information & Requirements For Electric Service Below 600V)

Metering

1. Services to power supplies shall be metered with a demand meter, unless the service meets the requirements for unmetered services (i.e. street lighting).
2. Pad-mounted meter units shall not be installed below the five (5) foot level without the approval of the Meter Department.
3. All pole-mounted installations and the orientation of the meter socket must be approved prior to installation.
4. Meters shall not be installed on poles unless the control unit itself is also installed on the pole. The meter location for pole mounted control units shall be at the five (5) foot level.
5. An approved lever-operated manual bypass is required on sockets (except for Residential Customers). 100 amp sockets may be supplied with non-locking jaws. Sockets greater than 100 amps must be supplied with locking jaws.
6. Grounds shall not be installed in meter socket(s).
7. A minimum three (3) inch conduit with slip joint is required when the service is underground
8. The non-bypassed, in-service position of the operating mechanism must be visible when the meter is installed. Auxiliary straps or jumpers are not acceptable as bypass devices. It must not be possible to override the bypass by replacing the cover when the operating mechanism handle is in the bypassed position.
9. Meter sockets for use on single phase three-wire 120/240-volt and 208Y/120-volt networks must have a fifth terminal located at left in the 9 o’clock position, connected to neutral.
10. Horn-type, Sliding-type & Automatic Bypass are NOT PERMITTED.
11. UNDERGROUND SERVICE: All underground residential single position sockets must be a minimum 16”W x 22”H x 5”D, 200 amp, ringless with line side lugs capable of accepting 350 KCMIL conductors. Sockets will also have a minimum 3- inch knockout to accept a 3-inch slip joint. If a service run is greater than 200 feet contact them&E. The bottom left side knockout is for line conductors only. Line conductors are on the left side so they won’t interfere with the bypass handle.
12. The lever-operated manual bypass is required to be single-handle operated:

• 100 ampere may be supplied with non-jaw release
• 200 ampere and 320 ampere must be supplied with jaw release

Meter Location

1. HG&E WILL DESIGNATE METER LOCATIONS FOR NEW OR CHANGED INSTALLATIONS.

a. All residential meters shall be located outdoors on the front or front side corner of the house. The front of the house is considered to be the side adjacent to our distribution facilities. 

b. Meters shall be grouped so as to keep the number of metering points to a minimum.

c. Instrument transformer enclosures should be located indoors in a suitable area readily accessible to HG&E.

d. Other specific exceptions may be approved. For example, grouped metering may be located indoors, in a suitable area accessible to HG&E, only if there is no acceptable outside metering location.

e. If after a review by HG&E it is deemed outside meter trough(s) are not possible to install, then remote meter disconnect(s) will have to be installed on the inside meter trough(s) at an additional cost to the Customer. 

2. The Customer will maintain a clear, safe workspace directly in front of each meter location, and a suitable approach to it. Such work space shall be at least four (4) feet wide, shall extend out from the meter at least three (3) feet, and up to a height of at least (6) feet. In addition, the meter socket must be located at least three (3) feet measured horizontally from a gas meter, regulator or propane cylinder.

Placards

1. All meter sockets must have a UL label. Any modification of a meter socket will void the UL listing and the manufacturer’s warranty, making it non-compliant with our approved standards.
