Purpose:

To achieve meter equipment compatibility with the Army Metering Program pursuant to Public Law 109-58, Section 103 of the Energy Policy Act of 2005. The intent is for all advanced meters to report their data to the installation energy reporting and management system Advanced Metering Data Management System (MDMS) Installation Level front end. This approach is consistent with UFC 1-200-02, High Performance and Sustainable Building Requirements, Paragraphs 2-4.4 and 3-4.3, Measurement, states: “All meters must be connected to a base wide energy and utility monitoring and control system using the installation’s advanced metering protocols. The installation of meters is required per DoDI 4170.11.” The advanced meters must provide data at least daily and measure at least hourly consumption of electricity in fifteen minute intervals.

1.0 All metering equipment shall be provided to allow full integration into the Niagara Supervisor Gateway which shall be referred to as EEDRS, and to allow the system to manage, store, manipulate, trend, and graphically present the data. The installation is not considered to be accepted until validation of the configuration in accordance with (IAW) site connectivity requirements. BPOCs (FPOC) and meters or current transformer(s) will be installed IAW the applicable device Security Configuration Guide, UFGS 25.05.11.

1.1 The Contractor shall include the BPOC/FPOC and all disconnects, mounting hardware, enclosures, wiring and conduit, and safety equipment as required and appropriate to complete the task and provide fully functioning meters with connectivity to the EEDRS for metering. Integration into the EEDRS system shall be accomplished with/by the base maintenance contractor, if needed any software and software updates/upgrades shall be approved by the Government prior to installation, and in accordance with site connectivity requirements. The Contractor shall provide a hardware and software list will be provided for all new equipment installed under this contract. The contractor will provide a complete network diagram that includes existing and new devices, to include clients, BLDs, meters, and networking equipment to provide a complete picture of the BCS system.

1.2 Utility Meters shall be installed to monitor electricity, gas, and water usage. Meters will be connected to a field control network utilizing either LonTalk (ANSI 709.1-C) over TP/FT-10, Modbus RTU over EIA 485, or BACnet over EIA 485. Generally, meters communicate over a local building-level network to a building/facility point of connection (BPOC/FPOC) which then communicates via the installation’s Network Enterprise Center (NEC) IP network to an "Installation Level Front End", existing EEDRS Gateway. Meter data is provided to the graphical user interface for display and to any associated EEDRS applications programmed to optimize operations. The data is then stored in a Structured Query Language (SQL) database. The SQL database may be the database regularly used by the EEDRS applications or a separate SQL database installed specifically for meter data. On a regular basis the MDMS Gateway, located in the DMZ (demilitarized zone) of the installation (outside the inner firewall), or RCC (Regional Cyber Center), retrieves data from the SQL database and sends it to the MDMS Enterprise Server.

Notes: At this time electric meters may not be connected directly to an IP network, as this is considered a non-standard approach.

1.2.1 The means for meter data transmission using open-protocols such as ANSI/CEA 709.1-C, Modbus RTU, and BACnet over Government owned transport media (LAN, telephone carrier, wireless, radio, microwave, or power line carrier, etc.) will be site specific and subject to the approval of the Network Enterprise Center (NEC). This guidance provides the flexibility needed to support the various data transmission system alternatives in addition to meeting the minimum standards for energy consumption data recording and reporting. A key element for success will be integrating these systems with the Army’s Information Technology (IT) networks supported by Network Enterprise Centers (NEC).

1.3 These requirements apply to all Army meters for use on facilities that meet the size and energy-consumption selection criteria regardless of the funding source and method of procurement (i.e. Military Construction Army (MCA) projects, Utility Privatization contracts, Energy Savings and Performance Contracts, or Sustainment Modernization and Repair projects).

Definitions:

a. Advanced Metering Data Management System Installation Level front end. This term as used in the guidance refers to the system that will collect, manage, and display the meter data for the local energy manager. The intent of the Army Metering Program is to provide the metering data to the local engineering staff first within the building automation system that can execute application programs to affect savings, and then transmit to the Enterprise Meter Data Management System, when activated.

b. Advanced Meters. For this guidance, Advanced Meters are those that have the capability to measure and record interval data (at least hourly for electricity), and communicate the data to a remote location in a format that can be easily integrated into an advanced meter data management system. EPAct Section 103 requires at least daily data collection capability; and although the policy requires at least hourly, to best analyze rate data, a 15 minute recording interval is recommended. Most advanced meters offer additional features which may be attractive to system owners. Advanced meters do not offer two way communications or a kill switch for power to the facility. These functions are normally associated with smart meters.

1.4 INSTALLATION LEVEL FRONT END COMPUTER

Open Protocol. The Installations Advanced Metering Data Management System Installation Level utilizes a Niagara Framework (Tridium) based Open System Host for the front end data management system. The Open System Host is installed in accordance with UFGS 25 10 10, Utility Monitoring and Control System (UMCS) Front End and Integration.

1.4.1 UFGS 23 09 00, Instrumentation and Control for HVAC;

1.4.2 UFGS 23 09 23.01, LonWorks Direct Digital Control for HVAC and Other Building Control Systems; and

1.4.3 UFGS 23 09 23.02, BACnet Direct Digital Control for HVAC and Other Building Control Systems.

These will all provide guidance on other specific communication media used on the bus side.

1.4.1 Perform minor ancillary work required to support equipment installation.

1.5 Meter Data Storage and Point Naming Conventions. The meter data shall be stored per the defined convention shown below in a full version Microsoft SQL data base for future retrieval by others. The Meter Data Management System (MDMS) Gateway will retrieve and re- transmit the meter data to an Enterprise Army Meter Data Management System. The government supplied Microsoft SQL database may be native to the Host Metering Front-End or an entirely separate SQL database dedicated to SQL data storage.

1.5.1 Existing UMCS systems point names vary by system capabilities and site conventions. The site naming convention must be followed where possible. Approval is required from HNC prior to alternative point name creation. This is to ensure there are no conflicts with the MDMS gateway requirements.

1.5.2 Primary equipment names:

1.5.2.1 Servers are named EEDRS. However, the local data center server naming convention takes priority.

1.5.2.2 Building/Facility Point of Connection (BPOC/FPOC). Name is by site and building. Use no space, period or dash unless system constraints dictate otherwise: SiteBuilding#. Example: FLW2200B

1.5.2.3 LON TP/FT10 channel names. Name in this order: Protocol Site Building#. Example: LON Wood 100. Note that here a space is used to separate.

1.5.3 The following point naming conventions are approved for new system installations: SiteName is the Post/Installation name.

Building# - is the building number containing the meter; it is always the number of the building, although that building number may include a letter.

Meter - is the meter type within the building: electric, gas, water, steam; use the word METER for electric meters and the words GAS, WATER, STEAM, BTU for the other types of meters.

Meter # - is the meter number (the nth number) within the building. Parameter - is the name of the measured variable

For single site systems: Building#_Meter_Meter#_Parameter Building#.Meter_Meter#.Parameter

BLDG_2315_METER_2_VOLTS_A_B BLDG_2315.METER_2.VOLTS_A_B

For multi-site systems, where a regional host exists: SiteName_Building#_Meter_Meter#_Parameter Sitename.Building#.Meter_Meter#.Parameter

Example: WOOD_2315_METER_2_KW WOOD_2315.METER_2.KW

Where a site area designator is required: SiteName_Area_Building#_METER_Meter#_Parameter

Example: WOOD_A_2315_METER_2_KW WOOD_A.2315.METER_2.KW

2.1 Cybersecurity Requirements

a. The process and related requirements to attain authorization for metering systems have been revised to Risk Management Framework. DoDI 8500.01, Cybersecurity and DoDI 8510.01, Risk Management Framework (RMF) for DoD Information Technology (IT) were published in March of 2014 and outline the Risk Management Framework processes. Commands should coordinate with their local NEC to ensure compliance with the assess and authorize approach outlined in RMF. Additionally, the MCX offers guidance to shape architectural templates and influence the design process for Army installations. This document is Technical Criteria for the Installation Information Infrastructure Architecture and is available upon request from the POC.

b. The Information Systems Engineering Command’s (ISEC) Military Engineering Directorate (MED, formerly IASED) in Fort Huachuca, AZ, has conducted testing and hardening for a limited number of metering host configurations that may assist in the development of documentation towards favorable authorization decisions. As the documentation is created for individual systems there exist opportunities to leverage this knowledge to engineer a metering system that will more easily be approved by the NEC. Coordinate with the installation Public Works on its approved to operate (ATO).

c. Networthiness: As of July 2, 2018 this process is superseded by the RMF Access Only proves. The use of a Certificate of Networthiness (CoN) if preexisting is allowed until its expiration date.. The selection of system and network components from the Defense Information Systems Agency (DISA) Approved Products List (APL) is encouraged, when available. There is also a list of preapproved software that identifies those that have CoNs. The Contractor shall coordinate all efforts with the appropriate installation NEC as well as higher NETCOM headquarters. When issued and certified, the Contractor shall comply with the applicable IATO (Interim Authority to Operate) Security Configuration Guide.

5.0 TESTING AND CHECKOUT

[Note: This section is not all inclusive of specific testing requirements. Additional testing requirements for proper installation of water, gas, and steam meters are above (piping test, pressure tests, etc.]

5.1 Performance Verification Test (PVT)

a. Perform all Testing, Adjusting, and Commissioning in accordance with UFGS 25 08 10, manufacturer’s recommendations, and referenced contract specifications and requirements. Provide certification of compliance. Prepare testing procedures as defined by product manufacturer’s standard published written testing procedures and in accordance with UFGS 25 08 10. All electrical meter product certifications shall be performed in accordance with the certification tests described in ANSI C12.20 for 0.5% accuracy class meters, unless noted otherwise below.

b. The Contractor shall complete a Performance Verification Test (PVT). The PVT shall demonstrate to the Government that the actual power utilized by the electrical service being metered is calculated and displayed on the meter display and/or software accurately. The services being verified will be a random sample selected by the Government. The PVT shall utilize suitable test equipment connected to the electrical service being metered that is capable of displaying instantaneous 3-Phase values of Voltage, Current, Phase Power Factor / Phase Angle, Volt Amperes, Watts, and Vars.

c. All safety measures for connectivity to an energized source shall be followed as outlined in Safety Manual EM 385-1-1, Section 11B (latest version). Connectivity to an energized source is contingent on approval from the Government Safety Officer and Government approval of PVT plan. Additionally, a compliance validation assessment will be completed by the Government at its discretion as part of the test and checkout process. Any deviations from the required configurations will require resolution or correction by the Contractor at no additional cost to the Government.

d. The PVT procedures shall encompass testing of the entire system: meter installation, operation, conduit and wiring, data collection at front end, etc. All meters (100%) may not be completely tested in the PVT; however, procedures should take into account the entire system for the meters that are tested.

e. Pre-determined electric meters will be chosen (based on the CFT data) to be fully tested during the PVT. The Contractor will dress out in protective clothing (as appropriate), connect power analyzer with rope or clamp on CTs to the feeds and compare the meter readings between the frontend and the power analyzer.

5.2 Contractor’s Field Tests (CFT):

a. Contractor shall test 100% of the meters, verify the accuracy, correct any problems, and submit a report to the Government for review. Testing shall include the front-end server and associated workstation. The CFT report shall only be submitted for approval after all issues have been addressed and corrected.

b. Provide the screen shots to display the following parameters, as applicable: Front-End:

· Screen shot showing all connected meters along with data values listed below

Electric Meters: (all values shall be per phase where applicable)

· Line to Line voltages (volts)

· Line-to-neutral voltages (volts)

· Voltage phasor angles (degrees)

· Currents magnitudes (amps)

· Current phase angles (degrees)

· Power: Apparent (kVA), Reactive (kVAr), Real (kW)

· Phase Power Factors (pf)

· CT ratio (i.e. 400:5)

· Electrical Service rating and type (i.e. 277/480-volt, 3Ph, 4-wire, 3CTs, 3PTs,Wye Connected)

· Phasor Diagrams

Pulse Meters (Gas/Water):

· Initial reading of actual physical meter dial to obtain baseline data

· Initial screen shots of front end values for the meter for the same date/time the dials were read.

· Second reading of actual physical meter dial to obtain baseline data

· Second screen shot of front end values for the meter for the same date/time the dials were read.

· Pulse multiplier values (1 pulse = 100 cubic ft)

· Pulses per revolution

· Accumulator baseline or offset values (if applicable)

· BPOC (Building Point of Connection) information or BLC (Building Level Controller)

· The initial (or baseline readings) shall be compared against the second reading for verification of the pulse meter. The difference between the gas meter dial readings will be compared against the difference between the front end readings. The differences shall be within the resolution of 1 pulse count.

c. The data which is accumulated (pulses) should have baseline data to compare for the CFT and during the PVT. The values at the meter dial (e.g. gas, water, steam) and the front end shall be recorded and compared to the values at another point in time. The delta between the meter readings shall be compared to the delta between the front end values to insure the proper multiplier, Lon address mapping, and programming are all correct.

d. CFT Submittals will be rejected if they do not contain enough information to properly verify meter installation and operation. If there is sufficient data in the CFT that supports a properly installed and functioning meter, only a visual inspection of the meter may be necessary during the PVT instead of requiring the Contractor to suit up and connect a power analyzer; however, the Government reserves the right to test any and all meters during the PVT as deemed necessary.

1.1.8 Provide all required Operations and Maintenance Manuals.

1.1.10 Provide a System Warranty. The systems, all ancillary components, mechanical equipment, electrical equipment, subsystems, data transmission systems, and all Contractor-furnished software shall be covered by warranty. The Contractor shall warrant all products and services provided under this task order (material and labor) for a period of one year from the date of Government acceptance or the offeror's standard commercial warranty period, whichever is greater. Upon any product/service failure during the warranty period, Contractor’s response time to restore system service shall be within the timeframes indicated herein. “Mission Critical Outages” will require a maximum of 4-hour response time during normal working hours and maximum of 16-hour response time for after hours (defined as outside 0700-1600) and one day to restore system operation. All other outages will require a maximum of three working days response time and seven working days to restore system operation. System outages assessed as “Mission Critical” will be at the discretion of the Contracting Officer or Contracting Officer’s Representative.
