General IntroductionFebruary 2016 1

Technology development by Ingersoll-Rand for broad distributed power market

1990s Ingersoll-Rand established R&D team to evaluate use of automotive turbomachinery in small gas turbines

2001 - 2004 Formed Energy Systems business and released 70kW turbine in 2001, followed by 250kW turbine in 2004 based heavily on very successful Dresser Rand KG2

2004-2011 Over 300 units of 70kW and 250kW units operating in field with over three million hours of operation in the full distributed power market (luxury hotels, hospitals, landfills, waste water treatment plants, local and remote oil fields

CORPORATE HISTORY

High uptime modular power solutions for the oil & gas industry

FlexEnergy: Shift to oil and gas focus

2011-2012 FlexEnergy acquired the IR Energy Systems business. Focus of business was on waste gas to energy green power initiatives.

2012 FlexEnergy identified oil and gas prime power market as best fit for the technology.

2013 Targeted technology application and business on oil and gas remote power providing reliable, low emissions electricity from well head and flare gas

Artificial lift (ESP, rod lift) Gas production facilities Compressor stations LNG facilities Offshore platforms

Continues to manufacture reliable, efficient small gas turbines FlexEnergy Headquarters, Portsmouth, NH

Gas Turbine Advantages Over Competition


Comparison to Competitors:Flex

Gas TurbinesDiesel

GensetsGas-Fired

Recip Engine

Low annual maintenance (Very few “Touches”)

Ability to consistently absorb and shed large power loads

Robust oil lubricated bearings

Rugged synchronous generator can start 100 HP (GT250S) & 125 HP (GT333S) loads

Utilizes resistive load bank to manage highly transient loads associated with artificial lift sites

Use of field gas vs. need to import more expensive fuel (Diesel, LNG + transportation) AND eliminates expensive and difficult fuel logistics in locations that have well/pipeline gas

Low emissions allows for easier permitting and ensures emissions limits are not exceeded

1. Increased production

• Low maintenance equals more uptime

• Better load handling means consistently higher uptime in real world applications

2. Decreased operating costs

• Eliminates need to buy expensive diesel fuel

• Fewer touches and less scheduled downtime than any recip engine

• Remote connectivity and monitoring enables data logging and diagnostics to be done offsite

3. Reduced emissions

• Reduce / eliminate flaring

• Patented, ultra-lean combustion system that produces low emissions and enables use in non-attainment areas

Process Flow Diagram (example)

Power from Tank Vapors (existing VRU at site)

Flex Turbine gas tolerance allows sites to use tank vapors as fuel


1) Existing VRU outlet becomes gas supply for Flex Turbine

2) VRU gas pressure regulated to ~550 kPa(g)

3) VRU gas used directly by Flex Turbine

4) Other site gas used as supplemental fuel to ensure continuous gas supply

Power from Tank Vapors (process compressor needed)

Flex Turbine gas tolerance allows sites to use tank vapors with process compressor


1) Tank vapors scrubbed and piped to process compressor

2) Process compressor (FLPS or client supplied) delivers 550 kPa(g)

3) Tank vapors used directly by Flex Turbine

4) Other site gas used as supplemental fuel to ensure continuous gas supply

Automatic Fuel Switching (primary gas to propane)

Flex Turbine gas tolerance allows sites to switch from field gas to propane


2) Propane is set up as back up when primary fuel shuts down

3) Primary gas pressure decrease to low level triggers switch to propane

1) Primary fuel is wellhead, casing, or other problem gas
