CenterPoint Energy, Inc.

Domestic energy delivery company in the continential U.S.

� Headquarters – Houston, TX

�Electric Transmission & Distribution - serves approximately 5,000 square-

mile electric service territory in the Houston metropolitan area.

�Natural Gas Distribution – sells and delivers natural gas to more than 3

million homes and businesses in Arkansas, Louisiana, Minnesota, Mississippi,

Oklahoma and Texas.

� Interstate Pipelines – operates two interstate natural gas pipeline systems

that together have 8,200 miles of pipe and handle approximately 1.5 trillion

cubic feet of natural gas each year; provides transportation and storage.

�Field Services – operates 3,700 miles of gathering pipeline and handles 426

billion cubic feet of gas each year; gathers, treats and processes natural gas

moving it from the wellheads to pipelines.

�Natural Gas Sales and Services – sells non rate-regulated gas and related

services to commercial, industrial and wholesale customers.


Pipelines & Field Services’ Situation

Corporate direction is to move applications off of

mainframes

� Mainframe software license & support costs are extremely high

and continue to rise

� Mainframe skill sets are becoming harder to find

Pipelines and Field Services’ core applications built on

Adabas and Natural on the mainframe� Need to assess the feasibility of migrating the Pipeline Gas

Information System and Gathering Gas Information System to the

open systems environment (Unix)

Get There Faster.

Pipeline & Field Services Applications Overview

6/29/2010 | Process World 2010 | 4

The Pipeline Gas Information System is a fully integrated interstate gas

pipeline gas management system for the Interstate Pipelines (CenterPoint

Energy Gas Transmission and Mississippi River Transmission). This gas

management system is made up of twenty-eight (28) applications. The system

provides all of the integrated applications from Business Associates (Customer

numbers, names, addresses, etc.) through Invoicing (Customer Invoice billing).

The system supports CenterPoint Energy Gas Transmission’s Tariff and

Mississippi River Transmission Company’s Tariff that is filed and approved by

the Federal Energy Regulatory Communication (FERC). The system supports

the standards of NAESB (North America Energy Standards Board), which are

mandated by FERC.

The Gathering Gas Information System is a fully integrated gas gathering

management system for the Gathering company (CenterPoint Energy Field

Services). This gas gathering management system is made up of fifteen (15)

applications. The system provides all of the integrated applications from

Business Associates (Customer numbers, names, addresses, etc.) through

Invoicing (Customer Invoice billing).

Migration Approach

Process

� Create Baseline Environment

� Copy Code from Mainframe baseline to Unix environment

� Continue Working on Mainframe Environment

� Copy Changes to Baseline Environment and Unix Environment

� Execute Acceptance Process on the Unix Environment

� Push Changes from Original Mainframe Environment to the

Baseline and to Unix

Pre-migration tasks

� Set up of open systems environment

� Preliminary Activities

� System Preparation for Migration


Migration Approach continued

Migration tasks

� Qualitative Analysis of the Application System

� Conversion of Data

� Conversion of the Application Systems

Testing

� Unit Testing

� System and Integration Testing

� Performance and Stress Testing

� Client Acceptance Testing


Mainframe and Unix Differences

Data

� Mainframe data type EBCDIC convert to ASCii (Unix)

� Adabas Hyperdescriptors converted to Superdescriptors

Natural

� Sort Sequence; numbers on Unix are less than alphas.

� Hex values have to be translated from EBCDIC to ASCii

� Case conversion lower to upper (EBCDIC, ASCii)

� Process statement not available in Unix environment

� External calls convert to CALLNAT or other

� JCL converted to Unix scripts or Cronus SCL

Conclusion

Very Successful Project

� Completed on time and on budget

� Programming Staff adapted quickly, successfully

Unix Responsiveness

� Online processes as fast or faster than the mainframe

� Batch processess remarkably faster than the mainframe

Internal & External Customer Experience

� Transition from mainframe to Unix was transparent

� ServiceLynx, ServiceNow!, AccuNom (web interfaces) remained

the same (backend was the only change)

� Internal users transitioned from Rumba to Hummingbird Exceed
