1 Keeping your Automated Devices Alive
CenterPoint Energy’s IG Deployment - Lessons Learned John Rush CenterPoint Energy Crew Leader- Intelligent Grid Deployment SWEDE Austin, TX May 1-3, 2013        

2 Automation History CenterPoint Energy (CNP) has had automation in place for over 40 years 1970’s - Substation relays - SCADA 1980’s - Remote Control Reclosers & Pole Top Switches - Distribution Automated Control System (DACS) 1990’s - Loop Sectionalizing - DACS 2010 – Department of Energy/CNP IG construction project begins IGSDs installed IGSDs installed; year end = 201 IGSDs installed; year end = 384 DACS converted to Distribution Supervisory Control and Data Acquisition (DSCADA) IGSDs installed to date, 4/11/2013

3 Legacy DACS Maintenance Program
Legacy DACS Maintenance Improvements DSCADA equipment monitored by Telecommunication & Control Systems Orgs SAP Notifications Intelligent Distribution Device (IDD) work orders dispatched via Mobile Data Distribution techs are DSCADA first responders System oversight and 30 day restoration metric Speaking points Legacy and IGSDs are monitored by a variety of groups; NOC, DSCADA Control, Distribution Control, IG project team The D2 FUW notifications are created by the NOC and allows for individual device tracking and restoration matrix history Work orders can be sent immediately to DSP tech (cap crew) and if necessary be referred Service centers are responsible for their devices and the reporting makes there efforts transparent

4 Intelligent Grid Deployment
≈ 31 Substation Upgrades ≈ 180 Distribution Circuits ≈ 600 Intelligent Grid Switching Devices (IGSD) ≈ 420K Customers Construction Schedule 14-19 installations per week 67% Complete YE 2012 100% by YE 2013 12kV & 35kV installations Site are fully commissioned upon completion of construction Minimizes out of service duration of manual switch upgrade to IGSD Allows for high volume of switch replacements in a small geographic area 7 crews working out of 6 service centers 5,000 Square Miles 2.3M Customers 16.4 GW Peak

5 Challenges and Opportunities
New Technology Firmware Dual communication requirements Distribution SCADA (DSCADA) Multiple Vendors (5 IGSD combinations) Failures & Material Issues Volume of installations demanded higher expectations Documentation of issues into a multi-departmental log Training Distribution Operations techs required training on new installations and maintenance of devices None of the vendor’s FW was ready for dual comms Telecommunications was required to preform a site survey and assist with commissioning New control system (DSCADA) templates had to be prepared for site specific devices and comms ESM historically has utilized multiple vendors for the following advantages hold cost down improve supply restrictions Typical yearly installs ranged devices per year, IG project installed 162 devices in a 2 month period Operation crews now needed to know how to commission and maintain the new devices, this was provided by ESM, Telecom, and Operations

6 QA/QC Vendors Vendor Audits Audit Reports Issue Resolution
Factory visits Audit Reports CNP provided feedback Good/Best practices Gaps and improvement recommendations Issue Resolution Return Material Authorization (RMA) Reports CNP encourages transparency with ALL issues Encourage synergy between CNP and Vendors during acceptance and installation CNP sent a team (operations, engineers, electricians) to each vendor (switch & controller) After the visit CNP would document the factory visit and reply back to each vendor with our observations and recommendations Failures fully investigated and CNP reviews and accepts report prior to resuming receiving or installing devices CNP expects the vendors to be candid and timely on any issue they or other customers identify Speak to some examples of vendor support; application engineers flying in to CNP, weekly conference calls, dedicated resources

7 QA/QC CNP Logistics Shops
New Pallet design (Facilitates Testing and Shipping) Shops Itemized checklist (Tester’s signature) Hi-Pot, Current Injection, and Relay Testing Communication & DSCADA Testing Kit (Distribution material palletized with IGSD)

8 QA/QC CNP (Cont.) Field Installation and Commissioning
DPD crew and Telecom tech onsite DPD crew and Distribution Controller partner to commission IGSD IGSD Commissioning Document QC Each site is independently inspected IGSD QC report Issue Log & Documentation All issues are documented into a central issue log Risk Management provides oversight

9 IGSD Test Farm IGSD Test Farm

10 Availability Report 4-11-13

11 Operational Opportunities
Improved System Reliability Critical Infrastructure is only out of service for short periods of time Existing Manual Switch replaced by IGSD within 2 days Existing IGSDs are out of service less than 14 days Efficiencies Gained IGSDs are fully tested prior to installation IGSDs are communicating upon construction completion (87%) Kits require less hot shot deliveries Early issue/problem detection Defined, Repeatable, and Scalable Processes
