Why JEA Chose MDMS?
•Key recommendation from SLB study
•AMI vendor was just a data provider
•JEA’s new Customer Information System (CIS) had not fully stabilized and adding complex interfaces to it was not feasible
•JEA built its own MDM system to store data, interface with vendor data base and eliminate/reduce new CIS interfaces
•Complexity and lack of internal SMEs in AMR lead to external vendor
Metering, Billing/CIS America 2008, San Diego, CA
• Single repository for all meter sources
• Easier access to meter data for analysis and business intelligence
• Interfaces to other essential systems (Outage management, System Planning, Data Warehouse, etc.)
• MDMS will be easier to change for BPL, mesh RF and other NMR technologies
• Easier to develop new exception processing in MDMS
Why JEA Chose MDMS?

• Network Asset Management
• Data Collection Service Upgrade
• Virtual Move In/Out, Service Risk
• Customer Service Enhancement (leak detection, excessive consumption, etc.)
• Recovering lost revenue by identifying meter resets
Scope of Initial AMS MDMS Project
Metering, Billing/CIS America 2008, San Diego, CA

Load ResearchHow Much Data is it REALLY?
Metering, Billing/CIS America 2008, San Diego, CA
• Aqua Lines – Missing 15 Min Data from Data Warehouse ‘stuck’ in MDM System
• ~13% of Total Intervals Missing
• ~30% Nov ’07 and ~40% Dec ‘07 15 Minute Intervals Missing from DW
• Intervals in Week Dec 21-28 Missing from MDM and DW….Why?
• Missing DW Data is Widespread Among All Rate Classes

Business Enablement
Metering, Billing/CIS America 2008, San Diego, CA
• Purpose• Provide formal structure and process for planning, decision making and policy recommendations to support JEA AMS.
• Scope• Monthly review of submittals from stakeholders
• Deliverables• Timely responses to submittals requiring action within jurisdiction. Capital funding approval issues will require additional approvals.
• Critical Dependencies• Involvement from all affected work areas• Affected areas must submit documents to AMSSC for due diligence review
• Constructive interaction among members and stakeholders

• Must have the highest level of sponsorship and buy-in
• Internal resistance will manifest itself in many different forms. Strong executive leadership is required with frequent reminders to the company that this is an important project.
• Have a vision/plan to use data beyond billing
• Develop separate system to house data and interface with other systems
• CIS is not the right system
Lessons Learned
Metering, Billing/CIS America 2008, San Diego, CA
• Deal with the organizational inertia to changes
• Don’t underestimate the scope of the process changes
• Use MDMS as the catalyst (and not a be all and end all system)
• Identify short and long term owners
• New method of doing business
• Identify the right ‘change agent’/early adopter
• Jobs will not necessarily be eliminated but they will change
• Partner with the right vendor
• AMR/MDMS is a new field for most utilities and so, finding internal resources with right skills/experience will be difficult
Lessons Learned
Metering, Billing/CIS America 2008, San Diego, CA
• Manage stakeholder expectation
• Requirements will be fuzzy at best. New requirements will be surfacing as you deliver basic functionality. You must have a process to enhance the functionally delivered at the same time as you are adding new functionality.
• Spend as much time as necessary crafting
the contractual relationship with your
vendors (You will be glad you did!)
• Use Six Sigma or other quality tools during
the project to run things smoothly

JEA Electric System• JEA owns and operates three generating plants and all transmission and distribution facilities.
• A fourth power plant, the St. Johns River Power Park (SJRPP), is owned jointly by JEA and the Florida Power & Light Company (FPL) and operated by JEA. JEA and FPL are also joint owners of Unit 4 at Georgia Power Company's coal-fired Robert W. Scherer Plant (Plant Scherer), which is located in Macon, Georgia.
• JEA produces 3.2 MW from a methane-fueled generating facility at the Girvin Road Landfill.
• JEA's System Installed Capacity is 3,213 MW, with a Peak Demand of 2919 MW at a 55% Load Factor.

• Outage Processing – MDMS will receive outage data within 6 to 11 minutes of outage and pass the data to FMS for processing similar to customer calls
• Restoration Processing – MDMS will receive restoration data within 6 to 11 minutes of restoration and pass the data to FMS; FMS will flag the outage as NMR verified restored
• Restoration Verification – FMS will send a list of meters to Cellnet (thru MDMS) to verify restoration status of each meter. Cellnet (thru MDMS) will send FMS status of each meter whether the service is restored, or is still out or other applicable status. OCC will use this process to perform
• Transformer restoration verification, Single lights out verification
• Call-back verification - FMS will now validate restoration status thru the NMR to eliminate/reduce requests to customer’for a callback when power is restored.
• Bellwether/Commercial Meters- better quality and more reliable outage and restoration data for bellwether meters (JEA specified) or commercial meters.
