Requirement

This report is being provided to the Deputy Under Secretary of Defense for Installations and Environment in response to the Utility Meter Policy Memorandum dated April 16, 2013.

No later than 1 year after publication of this policy, Components shall develop a MDMP, to be approved by the Deputy Under Secretary of Defense for Installations and Environment DUSD(I&E), which describes how each Component plans to develop advance meters/AMS and intends to use their meter data to manage energy and water use. MDMPs shall be informed through a bottom-up review of installations and shall inexplicitly establish a Component-specific metering goal for electricity and natural gas, based on distinctive attributes of Component buildings and operations.

The Air Force meter program is based in several laws:

10 U.S. Code § 2911 42 U.S. Code § 8253

Department of Defense:

DoDI 4170.11

Air Force:

DAFI 90-1701

AFMAN 32-1061

Executive Summary

The Air Force Meter Data Management Plan (MDMP) provides a lasting framework supporting the enterprise execution of advanced meters, advanced meter reading systems, and meter data usage. This plan enables the Air Force to effectively meet Office of the Under Secretary of Defense (OSD) and Air Force metering policies. Metering utilities is foundational to installation management and mission sustainment across the Air Force. Metering was initially mandated targeting energy conservation. This changed over time, and it now targets providing near real time monitoring of utilities and enable Energy Assurance.

Through the Advanced Meter Reading System (AMRS) program, the Air Force will install a complete system to include the approved meters, server, laptop and software suite. The AMRS program will then work with your local Communications Squadron to reconfigure your approved control system base network to enable communications to the AMRS at all Department of the Air Force (DAF) Active, Space Force and Reserve Duty installations. The AMRS installation involves two funding programs. The first program provides funds through the AFCEC FSRM AFCAMP IPL process. The AFCAMP IPL is a centralized program where funds are centrally sourced to have meters installed on critical facilities and infrastructure nodes, have a server installed and the base network configured. The second program is where each installation further expands the system by installing meters over time within SRM resources on additional buildings, reimbursable clients, sub-metering needs and MILCON projects as noted in statute. The complete investment is an integrated system allowing base wide coverage of cyber secure advanced “smart” meters, meter reading system software, and a secure industrial control system.

A fully deployed AMRS will provide bases with the ability to capture electric, water, steam, and natural gas consumption, validate utility quality and model utility delivery condition on buildings where the system is installed. These same meters will form the backbone to a load management system critical for efforts to install microgrids or a full utility management and control system. Because of this, the AMRS system should be considered a mission critical system as noted in the latest AF draft guidance memo on CE Controls and DAF Information Technology Categorization and Selection Checklist (ITCSC) with appropriate overlays.

The first priority for the centralized program is on installations with critical missions as outlined by OSD and DAF policy. The Air Force will evaluate mission needs and potential energy savings associated with AMRS to determine if the scope of the centrally funded program is appropriate to expand or restrict. New missions are continuously being evaluated as it is recognized that mission critical designation is not static.

The AMRS program management office (PMO) is the AMRS system owner and leads system tool and metric development to analyze meter data. The goal is to set Air Force level standards and determine the best approaches to manage both facilities and associated energy use. These metrics, executed in the form of standardized AMRS software reports, will enable bases with and without AMRS to manage their energy use in accordance with statutes, OSD, and Air Force policy.

Background

Energy Policy Act of 2005 was passed by Congress on July 29, 2005. This law required metering of electric on all federal buildings. The law required the U.S. Department of Energy (DOE) to establish guidelines for agencies to meter their facilities. The Energy Independence and Security Act of 2007 further established that each agency shall provide equivalent metering of natural gas and steam on their facilities. It is further noted that all MILCON projects (to include MILCON, UMMC, and ERCIP) as well as O&M renovations over $200K must include advanced metering by statute. Also, clients with over $100K in annual energy bills are to have approved advanced meters installed. Laws passed in the FY20 and 21 NDAAs specifically noted the need to use cyber-secure, sampling rates, the need to mirror crucial energy needs, and need for advanced meters to monitor mission critical buildings and their systems. Recent statutory, energy policy guidance and mission owner directives continue to expand the AMRS requirement to include shadow metering for whole base consumption, metering and sub-metering for critical loads, grid modeling and transient voltage analysis.

The Office of the Under Secretary of Defense established policy in 2013 requiring service components to accurately capture a minimum of 60% of electrical and natural gas use with a goal of 85% thru use of an AMS (Advanced Meter System). Additionally, it outlined requirements for the metering of all steam systems, data centers, communication nodes, and water intensive facilities. Metering is required at the building level as well as sub-metering major sub-systems as needed to ensure monitoring for mission assurance. The Air Force further refined metering targets in AFPAM 32-1061 with compliance monitored under AFI 90-201 self-assessment checklists for each installation. OSD as well as DAF policy required the creation of this MDMP to codify explicitly how the Air Force will execute the program and meet both statutes and policy targets.

Statutes, policy and guidance continue to evolve with the program. Installation POCs are recommended to regularly validate this document to ensure they remain in line with DAF direction. The core goal is to use metering as the backbone for near real time monitoring of utility status and condition. The goal directly empowers the ability to assure energy supplies to key missions as outlined in the Air Force Energy Flight Plan.

Further policy changes are expected, and this document is reviewed 2x/year and updated appropriately by AFCEC based on statutory, OSD and Air Force direction. Revalidation of this directive by SAF/IEE is completed as needed. Designers of facilities are recommended to reference this document to ensure compliance not to exceed one year out of project award to ensure compliance. Guidance in this document goes well beyond existing UFC, UFGSs or similar guidance documents to ensure compliance with all requirements. Current Air Force position precludes value engineering meters out of MILCON or SRM projects over $200K unless an approved advanced meter already exists. Connecting these meters to existing approved CE Controls environment (CE COIN or IROC) network will fall into the cost-effective evaluation criteria as noted in DAF and OSD guidance

Shadow metering and facility metering, owned by the DAF but on privatized utility systems is also allowed under the above noted statutes. AFCEC/CIU and AFCEC/CNP actively work to deconflict potential issues if this is required. Installations with metering issues on privatized systems should contact AFCEC/CNP. Use of privatized meters or 3rd party meters is not allowed as per OSD guidance. Meters could not meet requirements for data collection, islanding, cybersecurity and cost effectiveness.

Currently, the advanced meter way forward is based on a centralized asset management approach executed by a PMO within the AFCEC Energy Directorate at Tyndall AFB, FL. The AMRS PMO requirement is to accomplish the initial system install of the Air Force’s advanced meters. The initial install centers on installation defined critical buildings, crucial infrastructure nodes, and real property systems supporting those missions and nodes. Installation leadership and mission owners validate the install scope. Where applicable, 3rd party controls systems operating on the approved CE enclave will use approved AMRS meters. AMRS in turn will ensure vendors meet system architecture standards and understand and comply with support agreements for oversight of the meters. The goal is that a single meter will support multiple vendors and controls systems thereby avoiding repeated procurement of devices for different systems. The AMRS team will track and oversee all of these to ensure an integrated DAF system.

The Air Force’s AMRS’ ability is the principal driver in data automation to better inform investments. The Installation Resilience Operations Center (IROC) uses AMRS as a cornerstone as the Air Force moves into the ability to use data to automate decisions and centrally manage the ocean of CE Control System data.

Current Status

AMRS is currently the Air Force standard for smart metering. The AMRS PMO centralized and standardized on this platform to ensure cyber security requirements, software maintenance, network standards, and proper personnel for execution are maintained. A critical component of the AMRS is the installation of the approved CE controls enclave, CE COIN. This independent communication path provides a cyber-secure backbone for the AMRS system. The Air Force installed this cyber secure network at all installations. Air Force is now testing the next generation of a secure environment under the IROC.

The central install program secures funding under the Air Force’s central SRM Integrated Priority List (IPL). Bases are prioritized then validated by AFCEC and SAF leadership.

Projects are awarded thru the 772nd Enterprise Sourcing Squadron (ESS) at Tyndall AFB. A Contracting Officer Representative is needed for each install with technical reach back provided by the AMRS team. A base install effort averages 100-200 meters, shadow meters at sub-stations, server and laptop. The AMRS devices are considered Real Property Installed Equipment (RIPE) with servers and laptops considered Facility Operations Tech Investment (FO-TI) items. After install is accomplished, the system receives final commissioning and formal system training by the AMRS team.

The AMRS servers and laptops are transferred to each installation’s property books.

AFCEC/CNP will maintain the licenses as well as system ATO. They will also advocate for resources needed for server and laptop technical refresh. If centralized resources are not provided for server or laptop replacements, installations are expected to require needed resources thru AFIMSC/IZ under the FO-TI funding call.

System and network expansion beyond the initial installation is with the installation for funding.

Installation leadership is asked to contact the Energy Directorate (AFCEC/CN) if a follow-on installation project is needed due to mission change or some other factor. Each request is justified by that installation and evaluated against Air Force strategic priorities and available resources.

AMRS approved devices are capable of varying sampling rates and providing data to multiple CE Control Systems. The devices are specifically capable of validating effective delivery for high reliability requirements needing a 5 and 6 (a.k.a 5 and 6-9’s) level of service. The approved device listing and commissioning guides are under constant review and updating to ensure this can be meet.

Furthermore, the AMRS PMO in conjunction with the Measurements and Analysis division (AFCEC/CNA) will evaluate and analyze the energy data for trends, benchmarking, identifying anomalies, and other indicators enabling energy driven, asset management decisions for energy assurance, cost containment, and consumption reduction. Accomplishing these actions will greatly benefit the Air Force by increasing resiliency while managing valuable commodities.

Cyber Security Requirements

AMRS is centrally managed and controlled. This is unique in all Air Force control systems.

The AMRS system owner is AFCEC/CNP. The system’s Information Systems Security Manager (ISSM), and Information Systems Security Officer (ISSO), are also centrally located at Tyndall with AFCEC/CNP. The AMRS configuration and accreditation are also centrally managed. Installations are not responsible for these factors but any system risk, denial of service or interconnection should be forwarded to required authorities with a CC to AFCEC/CNP team.

Advanced Metering Infrastructure must maintain compliance with DoD Information Assurance and Cyber Security DoDI 8500 series requirements and Air Force Instruction 33210, The Risk Management Framework (RMF) for Air Force Information Technology (IT).

All AMRS components will utilize the CE COIN platform IT system for transmitting data from the advanced meter to a centralized server on the installation (Figure 1). As noted previously, the AMRS system is mission critical under ITCSC checklists, and will manage device configuration when connected to other CE-Control Systems.

Baseline configuration changes shall occur as events dictate, such as changes due to USCYBERCOM tactical orders / directives or cyber-attacks (Control Correlation Identifier (CCI) 000297). This policy shall be reviewed annually and updated as required (CCIs 000289, 000292).

Configurations will be strictly maintained for each AMRS core component (CCIs 001737, 001503). Currently, core AMRS components are comprised of the following items:

AMRS Host / Physical Machine AMRS Web Server Virtual Machine AMRS Laptop

The requirement for patches to the baseline system images for incorporation into the AMRS will be reviewed by the AMRS ISSM and/or the AMRS ISSO on at least a quarterly basis or within the timeframe required by the associated directive.

Patches that are minor in nature (such as those mandated by USCYBERCOM) and do not affect operation on the system should be promptly implemented under the direction of the ISSM or ISSO. The AMRS ISSM or ISSO will bring all remaining patches to the configuration control board (CCB) for evaluation and consideration for deployment. After CCB approval, patches shall be incorporated into AMRS, and an appropriate version number will be assigned according to CCB procedures. Baseline system images shall be patched at least every 12 months as required to sustain cybersecurity and functionality of AMRS.

The Air Force AMRS accreditation boundary is presented in Figure 1 of this document.

Meter Data Management and Use

The Air Force plan has two current tracks:

AMRS installed systems and bases Non-AMRS installed systems and bases.

For bases scheduled for AMRS, this system comes complete with software that enables the base to effectively see critical information about utility status, facility issues, and energy quality.

This includes, but is not limited to determining power factor, peak power, total consumption over time, and energy use. Sampling rate is initially set for 15-minute intervals but may go as low as 0.1 seconds for electrical meters to meet mission needs. The system also allows for additional reports and analysis as determined by AFCEC Subject Matter Specialists or the installation. This basic information allows for bases to perform:

Utility quality and status Microgrid operation and load shedding Anomaly and outage reporting Demand management programs Benchmarking of facility and facility system health Facility Energy intensity comparison Unit energy use comparison

Islanded microgrid management, demand side management and utility monitoring for mission assurance is core for meter data. Metering data is often the initial or only indicator of a facility with an issue which culminates in mission impact. This system identifies problems for Civil Engineers where equipment may require tune ups or load management. It will allow them to focus diminishing resources on maintenance, repair, or equipment replacement on those areas using excessive energy having the savings potential 5-15% of utility costs, as well as countless man hours troubleshooting utility system issues. It also provides critical data for facility retro-commissioning and implementation of other energy conservation opportunities.

The meter data is owned wholly by the Air Force and is a valuable asset for potential vendors.

Sharing of any AMRS data with outside organizations or vendors should include data restrictions and retirement requirements. Final disposition of AMRS data is under review, along with all other CE control system data, for applicability under AF PD 33-3 and AFI 33-322. No classification guide exists for AMRS data, but it should be considered Sensitive, and for limited distribution. AMRS data will follow any mission owner’s classification guide until such time the DAF develops and publishes its own CE-Control Systems classification guide.

The AMRS system is for real property assets and benefit of Civil Engineers. Industrial processes, mission systems, and privatized entities could benefit from the meter data also.

These users should work thru AFCEC/CNP to validate if a cost sharing model is required before data is provided. For larger potential uses of AMRS data, AFCEC/OEA, AFCEC/CO and AF/A4P are actively looking at potential uses. AMRS is actively able to provide the BLADE family data from its system.

Non-AMRS Bases

For bases that are not currently scheduled to receive AMRS there are two levels of action that need to be addressed:

1-5 years 6-10 years

For the one-to-five-year outlook, bases not currently projected for AMRS must comply with OSD and Air Force metering policies for renovation and new construction. See CE Dash and AFMAN 32-1061 for criteria. All new meter acquisitions should be approved by the AMRS PMO to ensure compliance with cyber security, software and hardware requirements. The AMRS PMO will continue to be the Air Force center of excellence for metering standards and deployment.

During the six-to-ten-year outlook, the AMRS PMO will validate scope for that installation based on mission needs and gain a vector if the centralized install will support the install at that base. The AMRS PMO will in turn brief this expected plan to AFCEC as well as SAF/IEE leadership as requested.

Bases with metering systems that are non-AMRS compliant shall look for opportunities to bring their metering system into compliance. This should include but not be limited to installing CE COIN or appropriate systems, repair by replacement of all non-compliant meters with AMRS compliant meters, coverage of the Air Force Network on key infrastructure nodes and ensure all new facilities and major renovations install AMRS compliant meters consistent with Air Force requirements. Expansion of the network to support CE COIN installation is done under the FO-TI program as part of AFIMSC/IZ’s portfolio. Installations should look at having pre-priced options in their SABER or other MATOC contracts approved meters to simplify installation.

AMRS Sustainment

The AMRS initial installation is centralized to generate an enterprise solution for metering software, hardware, and cyber security. Beyond the initial install, a long-term sustainment plan was necessary to ensure proper funding and personnel for the support.

Current Air Force position is centralized Air Force funding of the initial system to include needed servers, laptops and devices. All items are signed over to the installation upon system commissioning. The initial system install does not meet all statutory and policy directives but is done based on current Air Force position for cost effective metering.

The system is monitored day to day by installation Civil Engineer and Communications personnel.

This is done under the same MOU for all CE Control Systems. The local communications squadron is responsible for local network trouble shooting, Civil Engineers are responsible for trouble shooting when a meter or system device is not communicating. AFCEC/CNP will act as deep reach back and provide in person field support, as resources allow, only when all local troubleshooting efforts fail.

AFCEC/CNP is centrally troubleshooting and updating using remote methods. Installations should understand this to ensure maximize system up time for installations.

Additional training for new personnel is available on a first come/first served basis at other bases formal training. TDY fees are the responsibility of the requesting organization. AFCEC does offer some familiarization training and will continue to offer phone support as resources allowed. Virtual or computer-based training will be investigated for future educational opportunities.

AFCEC/CNP also retains system experts on a support contract. Requests for specialized configurations, reports or unknown issues may be referenced to these vendors. Installations may request support from these experts, but final allotment of resources is designated by AFCEC/CNP.

Summary

The Air Force MDMP is a comprehensive plan to bring the Air Force into compliance with OSD and congressional direction. This plan encompasses a systematic enterprise approach that provides a pathway for compliance with energy and cyber security policy. This plan should be reviewed, updated and approved at least annually to ensure the program is tracking towards the intended goals.

Meter Installation Guidelines Contractor shall assume all existing equipment is working properly. If, during the post award survey portion of the SOW, an existing piece of equipment is found to be malfunctioning, then the contractor shall bring it to the government's attention via the submittal of an RFI to determine how to proceed. This may require a contract change to delete this meter from the scope or to add a new meter.

All due diligence to survey the existing site conditions is the responsibility of the contractor.

New electric meter enclosures shall be installed in interior locations, located 5 feet above finished floor level, and as close to the main distribution panel as possible.

All metering device labels shall be white on black phenolic no smaller than 1” x 3” New meter installations shall include the installation of new, properly sized, split or solid core CTs as deemed to physically fit upon inspection by the contractor. It is part of due diligence of the contractor to design and install appropriately sized CTs into the space offered within the system. Rope-style or Rogowski CTs are not authorized.

Existing nonfunctional CTs are to be removed if possible. If removal is not possible, existing nonfunctional CTs must be shorted out.

If CT or voltage tap installation method includes disturbing the bonds of existing cables or wiring within the gear, before and after IR scans shall be performed before removing and after torquing the connections to ensure the integrity of the conductor bonds.

CTs shall be insulated. It is the responsibility of the contractor to design and install CTs of the appropriate amperage and size to accommodate the full load of existing gear. If the contractor intends to size the CTs from the breaker size, rather than the gear size, a RFI must be submitted requesting review and approval of said deviation.

Meter enclosures shall include fused, finger safe voltage disconnects and CT shorting blocks. Instructions explaining how to operate the CT shorting blocks must be visible inside each meter enclosure.

The meter must not require utility outages for servicing.

The CT shorting block ground wires must be installed on the load side.

Meters shall have control power regardless of breaker position.

All meter enclosures shall be fed by a load break 3-pole fusible disconnect switch that is external of the meter assembly. This safety disconnect switch shall be marked as follows “Meter Disconnect NOT Service Equipment” and any additional NEC labeling requirements.

New electric meter supply voltages shall be acquired by means of voltage taps from the bus or system breakers for the voltage system that the AMRS meter is monitoring.

Insulation piercing connectors are not an approved method and energized electrical work will not be permitted.

Electric meters with connected gas or water meter inputs shall have two internal registers configured - one for a raw pulse count and one for a weighted pulse count based on the scaling of the connected gas or water meter. It is the responsibility of the contractor to ensure that scaling ratios configured into the electric meter/device are accurate.

U.S. Air Force Page 17 of 19

All new communications equipment and metering devices are required to be enclosed in a lockable NEMA 4 or NEMA 4X enclosure. No other enclosure types are approvable for this project regardless of installation location.

Communications equipment must be installed in a separate enclosure than the meter enclosure.

Communication equipment and metering equipment should never be installed in an exterior location. In the event the contractor would like the government to consider communications equipment and/or a metering device to be located in an exterior location, a RFI must be submitted for review. If approved, the exterior meter enclosure must be a lockable NEMA 4X, stainless steel enclosure with panel that can completely cover the face of the meter and protect it from all environmental elements.

Cabling Installation Guidelines

New meter installations shall be connected via CAT6 cable from the meter to a wall outlet in the electrical room, to a patch panel in the communications room, and then to the AFnet switch in the communications room (base communication squadron will make the last connection to the AFnet switch).

All CAT6 cable runs must be continuous from the wall outlet to the patch panel with no intermediate patches or cross connects and are not to exceed 328 linear feet including patch cords.

The contractor shall verify the CAT6 cable termination standard, T568A or T568B, with the base comm squadron prior to cable installation.

Required technical approach to network communication cabling more than 328 feet is:

fiber optic cable and fiber media converters with lockable enclosures and dedicated power outlets.

When fiber is required, a minimum of two (2) strands are required per device connection.

TIAA compliant fiber media converter shall be installed in the communications room as close as possible to the network switch and as close as possible to the electric meter enclosure.

All cabling not installed above ceilings or behind walls shall be protected by conduit Communication receptacles accessible to the general public must be installed in lockable enclosures.

Cable labels shall be permanent, wrap-around and self-laminating with text generated by a mechanical device. Labels shall be applied at both ends of the cable, visible during normal maintenance of the infrastructure and resistant to environmental conditions.

All data cable test results (including fiber) shall be completed only after the cable has been terminated in its permanent location, temporary cable test results will not be accepted.

Surge protection is required on all communication cabling extending from the exterior to the interior of a facility. This includes gas and water meter communication cables from the exterior to the interior of the building.

Surge suppression devices shall be installed w/in 3 feet of the building entrance inside the facility. Devices shall be easily accessible and labeled to aide in location during future troubleshooting efforts.

U.S. Air Force Page 18 of 19

Surge protection devices shall be Power over Ethernet (PoE) compatible and housed within a lockable enclosure that allows space for a proper cable bend radius.

Fiber optic cable strands shall be terminated on patch panel bulkheads or within a fiber optic wall outlet assembly; unsecured connectors are not acceptable.

Fiber optic cable runs must use continuous fiber with no intermediate patches or cross connects and must not use mechanical splices or end terminations; all splices and terminations shall be fusion spliced.

Wireless Communication

As a general rule, wired communication utilizing the base network is preferred due to life cycle costs and ability to move data. Only by exception should wireless be considered for connecting of devices to the base network.

Any wireless communication protocol is considered sub-optimal. Wireless systems have proven to be cost prohibitive when trying to secure accreditation as well as long term sustainment. Any wireless communication for metering must meet all criteria in the AF Guidance Memo on CE Controls and be part of the AMRS ATO. In addition, any wireless communication must be approved by that installation’s frequency manager.

Wireless systems will need to comply with requirement for controls and be able to operate in an islanded installation. Collapse of systems or disconnecting wireless communication protocols shall also be part of an incident response plan for the specific devices on each base.

AMRS Compatible Gas Meter Specifications AMRS compatible gas metering solutions rely on accurately scaled output pulses, properly sized components according to peak demand, and peak pulse rates to eliminate the risk of saturating the receiving device ensuring the loss-less delivery of accurate gas pulse data into the AMRS system. The due diligence of the contractor shall be to coordinate with the appropriate base personnel to obtain all necessary information to effectively design and build a system that satisfies these requirements and conforms to the following specifications:

Pulse kit must be able to produce a two-wire (Form A) pulse output via exterior rated RS485 cable in conduit

Gas meter or attached pulse kit must include a visual register or dial All new gas meter assemblies shall include upstream gasket strainers All meter labels shall be white on black phenolic All cabling not installed above ceilings or behind walls shall be protected by conduit

AMRS Compatible Water Meter Specifications AMRS compatible water metering solutions rely on accurately scaled output pulses, properly sized components according to peak demand, and peak pulse rates to eliminate the risk of saturating the receiving device ensuring the loss-less delivery of accurate water pulse data into the AMRS system. The due diligence of the contractor shall be to coordinate with the appropriate base personnel to obtain all necessary information to effectively design and build a system that satisfies these requirements and conforms to the following specifications:
