9. Bowman Target Market(s)
Primary
Cogeneration
Applications where combined thermal and electrical power generated on site, is the most economic and environmentally sound solution to meet the sites energy needs. This includes chiller applications and boiler re-powering.
Power Quality/Secure Power
Where customers cannot tolerate power supply interruptions or transients that would interrupt their business. Traditionally this market has been met by investing in configurations of standby diesel generating sets and Uninterruptible Power Supply (UPS). A MTG solution can offer similar levels of protection but also provides an operating payback.
Secondary
Strategic mobile power, military and commercial, and Auxiliary Power Units
Peak shaving
Resource recovery; flare gas, land fill gas etc.
Mechanical (HVAC, Air and Refrigeration compression)

10. Market Strategy Global
BOWMAN will plan to serve the global market, focussing on applications and countries where demand for distributed power generation is strong (Japan, USA, Europe). BOWMAN has offices in Japan and California in addition to the UK.
Partners
Benefiting from early mover advantage, BOWMAN will partner with lead companies capable of high volume distribution in their specific territories and sectors. BOWMAN will not offer exclusivity to any one organisation, but may to a group e.g. (NTT, MITSUI, KUBOTA).
Target High Value Applications
BOWMAN will initially focus on niches, such as co-generation and secure power, rather than driving for the low cost / high volume needs of basic electricity only systems.

16. BOWMAN Product Status Power conditioners High speed alternators
Commercial sales commenced in 1999, more than 200 units at 50kW to 100kW have been shipped.
High speed alternators
Commercial sales commenced in 2000 and more than 150 units have been supplied to MTG customers at nominal ratings of 70kW, 90kW and 115kW. The first 165kW unit is currently being developed, and design studies have been completed up to 2MW.
MTG Cogeneration systems
Bowman is currently shipping a limited number of 50 kW and
80 kW systems on commercial terms to selected sites. Once this initial fleet has proven durability and performance BPS plans to release units for unrestricted commercial sales. The first commercial unit will be the 80kW, targeted for the end of 2001
MTG mobile units
The first nominal 30kW units for military use are currently commencing Beta site trials. Commercial production of the unit is planned for late 2002.

17. Business Challenges for the MTG Industry
Durable Systems. To provide robust durable Micro Turbine based systems with proven life of over 30,000 hours (before refurbishment).
Low Cost. By design and process achieve the cost targets (capital & operating) necessary to achieve the high volume sales
Channels to market. To establish distribution & support channels capable of supplying sustainable volumes and servicing the mass global market.
Continuous product development. To continuously advance the technology to improve systems efficiency, emissions and operational life.
Regulations and Standards. To access to grid, interconnectivity, common standards.
