## Highlights from the FEMP Advanced Metering Workshop

**September 25, 2003**
**Golden, Colorado**

## Overview

- Discuss guidance development process and structure
- Describe Advanced Metering technology
- Build a business case
- Discuss costs, strategies, and savings
- Consider government case studies

## Guidance Development Process

- Form an Ad Hoc Meeting Committee (AHMC)
- Composed of attendees at the workshop
- Gather input from agencies and private sector regarding
- Potential benefits
- Better energy management
- Improved O&M, cost savings
- Improved security
- Resources
- Constraints on appropriated funds
- Limitations on personnel
- Use of Alternative Financing
- AHMC will present Draft Guidance to the Interagency Energy Task Force (IAETF)
- IAETF develops Consensus Guidance
- Consensus Guidance reviewed by 656 Committee
- DOE Secretary issues Guidance

- Carr, 2003

## Guidance Development: Structure

- Produce a flexible framework that helps  guide agencies when they develop specific implementation plans.
- Agency implementation plans should consider
- Specific constraints
- Opportunities
- Energy program management benefits

- Produce a screening process that identifies the cost- effective application of metered data, such as:
- Energy unit costs
- Ability to respond to demand and charges
- Bill aggregation
- Total annual costs
- Energy intensity per square foot
- Potential energy savings projects

- Ream, 2003

## Guidance Development: Structure

- Exemptions granted on the basis of security or economic justification based on the lack of savings to cover the costs.
- Metering program reporting should be made through a simple change to the existing annual agency energy report.

- Metering should eventually include all energy sources (and water as economically appropriate) for which data use could result in better resource management.

- Ream, 2003

## Guidance Development: Structure

- Sub-metering can include any meters on a multi-building facility beyond the utility revenue meter, or metering of large energy users in an individual building

- Initial phases
- Access to existing utility revenue meter pulse data
- Metering of obviously significant buildings using rules of thumb, e.g. annual energy use over $X0,000

- Ream, 2003

## Guidance Development: Structure

- Guidance should outline a phased effort to start with easily implemented, cost-effective projects, and the use of early experience to refine follow-up efforts.

- Follow-up phases
- Identify and prioritize additional meter installation through a cost -benefit analysis based on assessment of the specific metering costs and related potential savings.

- Ream, 2003

## Purposes of Advanced Metering

- Utility
- Time-of-use billing
- Demand response
- Automated meter reading
- Distribution load management
- Energy management

- Analyze loads
- Manage peak demand
- Measurement & Verification

- Facility management
- Power quality
- Emergency / condition alerts
- Maintenance diagnostics
- Combine multiple BMS
- Financial management
- Load aggregation
- Cost allocation
- Budgeting, forecasting and reporting

- Burns, 2003

## Advanced Metering Technology

- Hardware
- Advanced “smart” meter
- Interval measurements
- Communication ability
- Sub-meter
- Separate loads by buildings, floors, etc.
- What to meter
- Electricity, natural gas, water, steam

- Software
- Data presentation
- Data analysis
- Gateways
- Data collection
- Communication
- Data format
- Transmission
- System
- Security, data storage and management

- Burns, 2003

## Building a Business Case

- Costs, benefits, issues, what-if’s
- Comes before RFP
- Yet needs feedback from RFP for cost calculation
- Determine needs
- Satisfy whom?
- Facility manager
- Energy manager
- Financial manager
- Determine goals
- Identify data sources

- Burns, 2003

## Building a Business Case

- Costs easy to underestimate
- Hardware
- Who owns, inventory
- Software (presentation)
- Data collection (communication)
- Data storage, system management
- Internal IT, outsourced ASP, SLA

- Burns, 2003

## Building a Business Case

- Costs, continued
- Installation, integration, project management
- Turnkey solution, internal team costs, onsite labor
- Training, evaluation
- Ongoing
- Data collection (communication)
- Maintenance, updates, upgrades, additions
- Re-training, re-integrating
- Labor

- Burns, 2003

## Building a Business Case

- Energy bill reduction, event avoidance, O&M improvement
- Facility management
- Load management, distribution
- Power quality
- Combined BMS
- Maintenance diagnostics
- Process scheduling
- Financial management
- Benchmark, target
- Budget forecast
- Cost allocation, aggregation

- Burns, 2003

## Building a Business Case

- Benefits, continued
- Energy management
- Fuel cost analysis, tariff / contract alternatives, on-site generation
- Demand response
- Measurement & Verification
- Administrative efficiency
- Automatic collection and reporting of energy usage, emissions, whatever monitored

- Burns, 2003

## Building a Business Case

- Issues
- Don’t underestimate deployment costs
- Project management
- Installation
- Integration
- Training
- Quantifying benefits tends to be conservative
- Begin with energy audit
- Prioritize projects according to payback

- What-ifs
- Pilots
- Scaled or segmented deployments
- Hardware alternatives
- Multiple goals
- Alternative energy contracts, providers

- Burns, 2003

## Deployment Issues

- Critical: identify members of team
- Critical: identify goals
- Type of report
- Source of data
- Installation site walk-through checklist
- One-line drawings
- CTs, PTs, enclosures
- Contact information for all entities
- On-site labor
- Responsibility for updates

- Burns, 2003

## Deployment Issues

- Getting the data is hard
- Integration
- MV-90, EDI, gateways
- Interruptions
- VEE
- Systematizing use is hard
- Advanced meter / energy information system is only a tool, not a result
- Expectations

- Burns, 2003

## Sub-Metering Costs

- _Item_					_Low_		_High_
- Electrical sub-meter		$400		 $600
- Data acquisition and              $600		$1000
- 	communications
- Wiring				$100		 $200
- Miscellaneous			$_100_		 $_200_
- Totals				$1200	$2000

- Lewis, 2003

## Sub-Metering Sample Strategies

- Install meters only with software for collecting data
- Metering with cost allocation software
- Metering with cost allocation and operational analysis and fine-tuning (Building Tune Up)
- Metering with cost allocation, intensive monitoring of major energy consuming equipment using specialized software and outside review of operations and verification of savings (continuous commissioning)

- Lewis, 2003
