2 Key Aspects of EPRI Independent Objective, scientifically based results address reliability, efficiency, affordability, health, safety and the environment Nonprofit Chartered to serve the public benefit Collaborative Bring together scientists, engineers, academic researchers, industry experts Independent Collaborative Nonprofit 450+ participants in more than 30 countries EPRI members generate approximately 90% of the electricity in the United States International funding of nearly 25% of EPRI s research, development and demonstrations 2

3 EPRI s Current Research Areas Power Delivery and Utilization Transmission Lines and Substations Grid Operations and Planning Distribution Energy Utilization Information & Communication Technology Nuclear Advanced Nuclear Technology Chemistry, Low-Level Waste, and Radiation Management Equipment Reliability Fuel Reliability Long-Term Operations Materials Degradation/Aging Risk and Safety Management Used Fuel &High-level Waste Management Generation Advanced Coal Plants, Carbon Capture and Storage Combustion Turbines Environmental Controls Major Component Reliability Materials and Chemistry Operations and Maintenance Power Plant Water Management Environment and Renewable Energy Air Quality Energy and Environmental Analysis Land and Groundwater Occupational Health and Safety Renewable Energy T&D Environmental Issues Water and Ecosystems 3

4 Natural Gas Pipeline Compression - Overview Natural Gas Pipeline compression is the process of using compression stations to move natural gas from one location from initial collection to end use distribution Typically these stations are utilized every 40 to 100 miles within the pipeline Three key spaces Upstream (Gathering & Processing) Midstream (Compression, Transmission, and Local Distribution) Downstream (End use) 4

5 Natural Gas Basins 5

6 Natural Gas Trends NG prices are currently around $2.90 MMBtu NG use is increasing in various sectors including power production Production is continuing to increase / expand Numerous companies are expanding and have plans to focus on the Marcellus / Utica reserve due to potential capacity and proximity to large population centers 6

7 Natural Gas Pipeline Compression - Summary Electric Powered Natural Gas Powered Advantages Disadvantages Advantages Disadvantages Minimal to No Local Emissions Requires High Voltage Electrical Infrastructure Operational Fuel Is Present at Station Local Emissions Reduced Long Term Maintenance / High Reliability Installation cost of electrical infrastructure Faster To Install IF Gas Infrastructure is present Slightly reduces gas in the pipeline (If electrical service not present and if no alternate billing policy can arranged) Source Fuel Only Has Generation Emissions Compression stations are typically remote so access to resources can be constrained Variance within local permitting Modern Drives create no problematic harmonics Minimal Electrical Service Required Routine Maintenance Reduced Permitting Time Potential Need For New Substations 7

8 Natural Gas Pipeline Compression Marketplace This lead time is typical for all surveyed equipment suppliers for normal configurations, some custom systems require 18 to 24 months for manufacturer Natural Gas Compression Systems and JW Energy both provide NG and Electric powered systems Stations are typically built with 3 online, 1 swing / spare drive to allow rotation of wear and maintenance Typical cycle is run three for 500 hours and then rotate the offline engine into work and swing one out to allow for maintenance and even wear Sometimes spare / swing is a smaller system just for emergencies Natural Gas powered engines are basically modified diesel engines Caterpillar is 85% of market / Waukesha is the other 15% / Cummings is <1% currently 8

9 Pipeline Compression Emissions The typical emissions from a NG powered system are as follows Natural Gas Powered Systems are typically selected when electric infrastructure does not exist Electric systems are typically selected when emissions are problematic or when sufficient infrastructure is already installed Electric systems have no local emissions Electric Motor Systems typically only require checking values and compressor oil regularly, but typically do not require over halls 9

10 Pipeline Compression Noise Northside 30 away Southside 30 away At Panel nearest compressor Electric 86 dba 82 dba 90dBA Motor NG Drive 89 dba 86 dba 93dBA FERC mandates that at the nearest noise sensitive area (homes, schools, etc) that the noise level not exceed 55dBA. This is viewed by some in the industry as the mandated level at the nearest fence post. Electric powered plants operate 2 to 3 dba lower then a NG powered station typically Even 1 or 2 dba can be noticeable in many environments The chart on the left is field collected data from a vendor Use of magnetic bearings, instead of lubricated bearings, in can further reduce noise by 2 to 3 dba 10

11 Pipeline Compression Expansion Plans There are numerous plans to expand lines already in place within the Marcellus / Utica (Appalachian Basin) Many of these new lines are in the AEP area 11
