Akutan Project
Phase III Coordination Meeting
7 January 2014
L Green Notes and Commentary
Cost Estimate
The level of cost estimate for the plant and wellfield piping was discussed. During
the last coordination meeting it was decided that the estimate would be to a Class 3
Level. However, GRG and RMA considered that perhaps only Class 4 was
appropriate given that resource performance is not definitive. John Mathew (JM)
and I stated that we could probably do somewhat better than Class 4. We advised
that our estimates would identify the confidence interval(s).
Other cost estimate items:
• preliminary estimate due the end of February, final due mid-March
• materials and equipment should be estimated FOB Seattle or Tacoma
• aggregate will be assumed to be brought in and not generated from sources
on Akutan – one recent datapoint is $120 per cu yd delivered to Akutan
• we will assume rebar, sand in bags, and cement in bags are included in our
estimate – JM and GDA to coordinate and use similar pricing
GRG will coordinate for quantifying the cost to produce and transport concrete
using a batch plant.
Plant Size
The plant will need to net 7.5 MW corresponding to Trident’s electrical peak. GRG
will confirm in what season(s) this peak occurs so design ambient conditions can
be selected.
In addition to the electrical peak, it was decided that the plant would have extra
capacity to provide space heating for the Trident plant. According to Mannvit, this
load is 1.7 MW thermal, which is also 1.7 MW electrical assuming electric
resistance heating. JM will include as part of his scope the details of implementing
electric heat input into Trident’s existing space heating system and will provide
Class 4 costing in his scope.
Until more is known about the timing of peak loads, the size of the plant is still a
bit undefined. If the 7.5 MW peak is a summer peak, and the 1.7 MW spacing
heating load is a winter peak, the plant size would likely be smaller than if they are
both assumed to be winter peaks. Consideration must still be given to daytime
summer ambient and coincident load, particularly if the plant utilizes dry
condensing.
Plant Type
Although the screening study identified non-condensing as an attractive choice,
several factors are now making condensing more attractive:
• GRC has stated that at least one stakeholder is opposed to releasing
hydrogen sulfide.
• There is concern that Alaska’s permitting agencies will require mitigation of
hydrogen sulfide.
• Mitigating hydrogen sulfide from a non-condensing plant is not common
whereas mitigating hydrogen sulfide from a condensing plant is common.
• The cost of drilling will likely increase from the estimate in the screening
study – this makes non-condensing have a higher risk profile due to the
lower conversion efficiency compared to condensing.
Phase III will therefore assume a condensing plant.
GDA will consider several types of cooling systems including, but not necessarily
limited to, the following:
• a base case of conventional direct contact condensing with wet cooling
tower
• air-cooled condenser
• use of a surface condenser with closed loop dry heat rejection
Each system has advantages and disadvantages relating to cost, freeze potential,
wind resistance, NCG removal and treatment, condensate management, etc. GDA
will evaluate options and make a recommendation.
Number of Units
Given that most operating personnel would rather have one unit vs. multiple units,
GDA will evaluate this approach. However, it could be that the best choice is not a
single unit for these reasons:
• At low load a single unit might not be able to operate safely with the
amount of turndown required, which would mean either using a load bank
or shutting the unit down and operating a diesel unit.
• Very remote locations often lend themselves to a high degree of modularity
in the design of the plant in order to simplify installation.
GDA will evaluate these issues and others related to number of units and make a
recommendation.
Plant Location
JM has a concern that the cost of running piping from the high location where the
wells are located to the proposed plant location in the valley would be too costly.
GRG offered the following:
• There is no significant difference between the two locations in terms of
snow accumulation. If there was, then building the plant at the high
location might be less attractive.
• There is ample precedent for geothermal plants located in environments
typical of the high location so this does not introduce undue risk.
Mead and Hunt stated there is no difference in the road design from the harbor to
the valley location compared to the portion that continues up the ridge to the
wellfield location.
It was decided that the plant would either be co-located on a well pad, or would
be located nearby where some level of protection might be afforded due to a
“nook” in the terrain. GRG to advise.
For planning purposes at this time, the plant footprint was discussed as being about
2 football fields in area, with an aspect ratio that could be adjusted to fit terrain. It
could even have a terraced construction.
It was also decided to keep the location in the valley for a maintenance yard, the
size of which preliminarily is one football field in area.
Transmission and Interconnection
GDA will provide design and costing of the substation within the fence. JM will
design and cost the transmission system to Trident. Due to concerns about the
reliability of overhead transmission, JM is looking at cable tray. He will look at the
Mead and Hunt map(s) and determine a preliminary route for team consideration.
GRG will confirm if the interconnection at Trident is to be part of the Phase III
work. In all likelihood a stepdown transformer and switchgear would be required.
Perhaps this only be defined to a high level corresponding to a Class 4 or 5
estimate.
In line with the Mannvit study, GDA will assume a generator and transmission
voltage of 13.8 kV.
Wellfield
JM decided to base his design around wellhead separation rather than a single
separator at the plant. There will be brine pumps at the production wellheads to
deliver brine to the plant whereby the brine pressure will be increased by injection
pumps, initially sized at 500 hp of total load. JM and GDA will coordinate to
determine the total wellfield parasitic load.
It is not clear if the injection pumps are part of the plant (GDA scope) or part of the
wellfield (JM scope). GRG to confirm.
Removable shelters will be provided over wellheads.
Steam piping up to the demister(s) is JM scope.
GDA will include a rock muffler.
GDA will include a condensate handling system as part of its scope that will be
coordinated with JM’s wellfield scope. Condensate is assumed to be provided for
disposal at 60 psig.
Hydrogen Sulfide Mitigation
Given the uncertainty of the regulatory environment and statements made by a
stakeholder, it was decided to include hydrogen sulfide mitigation in the project.
GRG recommended a regenerative thermal oxider as the type of technology
appropriate for this application.
GRG will gather up all relevant information such as first cost, footprint, outside
energy requirements, chemical use, cost and storage requirements, freeze
protection, and waste stream parameters.
GDA will assume the outlet pressure of the gas extraction system needs to be 15
kpa g.
Other
Other basis of design parameters include a 130 mph design wind speed and a
lateral seismic design factor of 0.5g.
GDA is to provide GRG a list of deliverables by EOB Tuesday, 14 January. GRG
requested that GDA review our proposed scope and report if we feel there are any
significant variations given the discussions that took place 7 January.
Alan,
I think we should somehow back up the assumptions for the number of wells. I found this tantalizing article summary (one
would have to purchase it to get the whole thing) that has the type of information that would provide the back up I think we
need.
Drilling performance, injectivity and productivity of geothermal wells
Abstract
Drilling performance of 77 high-temperature production and reinjection wells in the Hengill Area in Iceland was
analyzed. The results demonstrate that the perceived high risk of drilling in a proven field is less than commonly
thought. No difference was found in the time required to drill holes of or production casing but the
wider wells delivered 30–40% more steam. The average power output per drilled well amounts to 5.9 MWe but 7.5
per productive well. To predict steam mass flow on the basis of the Injectivity Index one must consider reservoir
conditions and enthalpy of the expected inflow into wells.
Keywords
Drilling cost; Drilling performance; Drilling risk; Geothermal; Injectivity; Productivity
These are the figures from the article that I found interesting: steam flow at 8 bar discharge pressure and injectivity index.
Frugal people that don't buy the article only get very tiny versions.

I have no idea if these 77 wells could be considered representative, but picking mid-range values from something like this
could be our basis.
For instance, we need about 150,000 lbs per hour total to get 7.5 MW net if condensing and about 260,000 lbs per hour if
non-condensing. We would be looking at injecting 800,000 lbs per hour and 1.4 million lbs per hour, respectively.
From the information in this paper, the assumption that two production wells are required for a non-condensing plant is OK,
but it appears equally likely that 4 production wells could be required.
Assuming a slightly optimistic injectivity index of 10 kg/s per bar, one injection well could take 635,000 lbs per hour without
needing an injection pump. To inject the 1.4 million lbs per hour for non-condensing, and using one well, we would need to
add 9 additional bar of pressure or so, which would take 250 kW of parasitic load and an expensive pump. And you might
want two for redundancy.
These are the kinds of things that need to get into a Basis of Design for the power plant.
So, is there some body of work out there that we can used to develop a basis for well performance?
Best, L Green
Akutan Phase III GDA BOD Comments - 30 December 2013
Reference: 30 December 2013 Basis of Design by GRG
1. The basis of design is going to be a bit broader as it should include more
areas than just the resource, such as:
a. seismic design factor
b. design wind speed and direction
c. design temperatures including wet bulb and minimum dry bulb
d. geotech parameters like soil bearing pressures
So perhaps the Project needs a BOD where all assumptions exist, and this
BOD is just resource related.
2. The basis for the required injection capacity will be reviewed by GDA.
There are a few items of note:
a. The DiPippo information includes assumptions that may not be
appropriate for Akutan. A separation pressure of 3.6 bar a may not be
practical due to the relatively large specific volume of the steam. In
other words, turbines may not be available that will accept enough
steam at this pressure and still meet other requirements, like number
of units desired. If the resource can be considered large compared to
the load, a higher separation pressure may be more attractive.
b. The specific output of 86 kW/kg/s probably reflects gross output, not
net output. Once the well performance is defined, GDA will
determine mass flows required to meet the design net power at the
design wet bulb (assuming condensing).
3. The production well performance assumptions should be set so they are
justifiable based on well performance at other similar projects. The two that
are mentioned are perfect. Assuming a performance at, say, 75% of the
average should be defendable, which likely means that two production
wells will do nicely, and it can be stated that only one might be required.
Seems like including four full-sized wells in the budget makes sense (one
duster!)
4. It almost seems like there is a rationale in the BOD for condensing vs. non-
condensing in the context of H2S, but if so, it is a bit weak as both are in the
same permitting category. Also:
a. Treating for H2S is a significant issue that has yet to be addressed by
any team member.
b. Assuming a condensing plant, is it possible to compress the NCG and
reinject it without introducing a corrosion risk to the injection well?

If you’d like the benefits of efficient and safe
overhead material handling, but don’t think your
building is structurally or financially suited for an
overhead crane, check out the NOMAD from EMH.
Buildings like those listed below may not work well
with standard overhead cranes, but the NOMAD will
adapt for the following reasons:
NOMAD
finds a home in:
Precast Concrete Buildings
The NOMAD can often be installed without footers,
eliminating the need for digging through and
damaging existing floors.
All of the NOMAD’s connections are bolted for easy
disassembly and relocation. If you think you may
move sometime in the future, you can easily take
the NOMAD to a new site.
The NOMAD’s free standing structure supports
loads your building’s steel might not handle. And the
low overhead design allows it to fit into sites where
headroom might otherwise be a problem.
Think again if you’ve ruled out an overhead crane.
NOMAD can give you the material handling you
need at a price you’ll like. Call EMH today for
details.
Leased Buildings
Buildings not designed specifically for
overhead cranes.

Sprung Structures for Power Plant Application
Geothermal Development Associates is designing a small geothermal power plant
for a project located in Akutan Alaska. The project is in the final phase of feasibility
study, which includes detailed cost estimates of road construction and drilling, and
a somewhat less detailed cost estimate of the plant proper. As such, budgetary
estimates to the ±15% level are acceptable.
Wellhead Shelters
The design team feels that having shelters at each wellhead would be advantageous
as the wellheads will have certain infrastructure that should be out of the extreme
weather. There are currently three wells envisioned for the project, so three
wellhead shelters are required.
A typical wellhead structure should have the following features:
• ability to be removed in one day and replaced in one day – sometimes a rig
will have to be brought in and located over the wellhead to do remedial
drilling
• footprint as indicated below:
• no insulation
• ridge-mounted or sidewall mounted spun aluminum exhaust fan with
corresponding motorized low-mounted intake louver sized for 5-minute air-
change
• roll-up door, not insulated
• mounting to concrete foundation by others

Powerhouse and Road Maintenance Building
The power generation equipment, electrical gear, control room, and certain
auxiliary equipment are anticipated to be located inside an insulated powerhouse.
A similar structure will be required for a road maintenance facility – the only
difference from the powerhouse is that this building will not be insulated.
The powerhouse and maintenance facility should have the overall dimensions and
features shown below:
The powerhouse should have the following features:
• Assume (4) piping penetrations will be required, each 20” in diameter and
12’ AFF.
• Assume insulation to R30 level, with insulated mandoors and roll-up doors.

Common Features
All structures should have the following additional features:
• The design wind speed is 130 mph and the design lateral seismic
acceleration is 0.5 g.
• The structures do not have to have the exact dimensions shown –
dimensions can be changed to meet standard lengths as required.
• Heating, plumbing, and electrical are by others at this time.
• Provide engineering for permit, drawings for approval, and erection
supervisor for remote Alaskan location.
• Quote erection manhours, crew size, and crane requirements.
• Provide simple plans and elevations of similar buildings provided by Sprung
in the past.
• Assume all materials are to be transportable in standard 40’ sea containers.
• Estimate the number of shipping containers for all three wellfield structures
together. Estimate the number of shipping containers for both the
powerhouse and for the maintenance facility.
