Winter Look Back (‘15/’16)

• Projects Placed In-Service(11/1/15):

– Horsepower Replacement at 245

– Broad Run Flex Project (~590K/d Capacity)

– Niagara Expansion (~158k/d Capacity)

• Peak Day was ~10.3 Bcfd on Jan 19, 2016 - Deliveries

• Peak Day was ~1.3 Bcfd on Jan 22, 2016 – Storage (withdrawal)

• Peak Day was ~1.9 Bcfd on Feb 9, 2016 – Power Plant Load

• Storage Inventories remained at high levels

– 29% higher than the levels for 2014/15 and 45% higher than 2013/14.

• System Challenges

– Short Term Unit/Pipeline Issues

Summer Look back Summary

• System Demand relatively flat compared to previous year

– Power Loads Increased / LDC Loads Decreased

• Storage Inventories remained at high levels for 2016

– 49% higher going into summer compared to 2015

– 58% higher going into summer compared to 2014

• System Challenges

– Maintenance • Pipeline Hydrotests / Spike Tests

• Station Reversals

• ILI Pig Runs / Pipeline Remediation

– High Storage Inventory in Northern Storage Fields

WINTER READINESS

Winter Readiness - Operations

• Scheduled Maintenance – All routine compressor station maintenance in the Market Area shall be completed by

early November. Examples include: • Station/Unit Protective Devices

• Compressor maintenance

• Borescope Inspections

• Device Calibration/Testing

• Test run units (as applicable)

– All routine pipeline and meter station maintenance in the Market Area shall be completed by early November. Examples include: • Annual Valve Maintenance

• Auto Closure Checks

• Boiler Maintenance

• Device Calibration/Meter Tests (Ongoing)

• Winter Event Preparation – Check/Test run emergency equipment (i.e. generators, heaters, etc)

– Field Operations will be on site at key compressor stations during significant winter events.

14

Winter 2016/2017

• Anticipate Colder Weather than last winter across the system

• Strong Market Demand

– 100 Line (South Texas)

– 500 Line (Station 87 to Station 527)

– 200/300 Line (Station 200 to New England Area)

• Exports to Mexico and Canada to remain strong

• High Storage Utilization

• Southbound Capacity Utilization to remain high through OH and KY
