Combined Heat and Power Plants

7. New Strategy with Well-head Units (WHU)
Conventional Centralized Plants
 Pros
▪ Geothermal fluid mix averaging
▪ Easier to deal with well/field decline
▪ One electrical substation for connection
▪ Higher unit efficiency—traditionally the case, but not
always true now
 Cons
▪ One pressure system
▪ Long lead times for tendering, equipment delivery
and project development
▪ Large fluid gathering piping systems across the field
▪ More challenging to finance
Well Head Units (WHU)
 Pros
▪ Early power generation
▪ Multi pressure system option
▪ Simple construction
▪ Permanent or portable options
▪ Limited gathering system piping
▪ Superior overall plant availability
▪ Easier to finance
▪ Greater ability to utilize entire resource
 Cons
▪ Distributed operation / maintenance
▪ Medium Voltage collection system
▪ Make-up well allocations
• Plant on very well pad in high enthalpy areas
• A row of combined heat- and power plants in medium enthalpy areas

8. • Output 0.2 – 20 MW
• Delivery time after
engineering: 4 months
• Manufacturing
financing
• O&M available
Well-head Units

9. • Sorik Marapi 240 MW
• Sokoria 30 MW
• Samosir 110 MW
Portfolio Asia: Indonesia

10. • Shares aquired April 2016
• Commencing with Drilling
Works in November 2016
• Commissioning of first
phase April 2018
• In 18 months from Spud-In
to Commissioning of first 15
MW
Sorik Marapi Indonesia 240 MW

11. • Maximum temperature measured
is 290°C at A-103
• Temperature increases towards
the western section of the field
into Mt. Sorik Marapi volcano
• Outflow appears to exist to the
southern sector of the field
where Pad C wells were
targeted; outflow the northern
sector has yet to be drilled and
confirmed.
Sorik Marapi Indonesia 240 MW

12. • Mobile testing units for
enabling testing during
drilling works
Sorik Marapi Indonesia 240 MW
