Renew Energy (www.renewenergy.dk ) is a
Danish biogas engineering/operations
company. Renew has successfully designed and
operated several silage biogas projects across
Europe and the United States.
The following selected references were
executed by Renew Energy A/S and/or by
Renew’s principals. Renew has 20 years of
experience in international biogas projects with
organic feedstock. In all projects, Renew was
responsible for start-up operations, running-in
and training of operators as well as ongoing
services for optimization of plant operation,
new feedstock etc.
5. EPC Contractor
5
Tibbar has retained Layne as its EPC contractor for the anaerobic
digestion (biogas) and power generation components of the project
Layne-Christensen is a $1 billion global construction company with over
6,000 employees www.layne.com
Layne’s European partner, Entec, an Austrian biogas engineering
company, has built over 200 commercially operating silage AD power
plants. www.entec-biogas.com/en/
Layne has extensive experience with biogas projects and provides a full
wrap guarantee with one year of operation.
6. Diversification of Renewable Energy Portfolio
6
Biogas generation from anaerobic digestion creates
permanent jobs
Wind and Solar provide intermittent power based on
meteorological conditions while biomass provides continuous
prime power.
Tibbar’s Biomass project diversifies USVI’s renewable energy
portfolio
7. Three components of a Biogas Operation
7
Biomass projects require three components:
(1) Organic Feedstock
(2)
(3)
Anaerobic Digestion Facility (to create biogas from
the feedstock)
Power Generation (converting biogas to electricity)
10. What is Anaerobic Digestion and how
does it produce power?
10
In the absence of oxygen, naturally occurring bacteria breakdown organic
material (such as agricultural energy crops like Giant King Grass).
This results in the creation of methane and carbon dioxide, which
make up biogas. This process, called anaerobic digestion, occurs in
large enclosed tanks. The biogas is collected from the anaerobic
digestion tanks and is processed through a generator to produce
renewable electricity.
11. Is Anaerobic Digestion currently being used
as a Renewable Energy Source?
11
For the last 30 years, Anaerobic Digestion
technology has commercially produced base load
renewable energy (primarily in Europe)
In Germany alone 3.8 million homes are fed
power from organic feed Anaerobic Digesters
Today over 10,000 plants operate in Europe in
small towns and agricultural based communities
The USVI’s fertile agricultural land and tropical
climate make it an ideal location for a biomass
project using agricultural energy crops.
19. USDA listed GKG as one of the Top 10 energy crops in 2012
19
Tibbar has the 20 year exclusive license for this product in the USVI
The fresh cut silage would be cut on the farm and transported to and fed into the
AD tanks daily
Characteristics of Giant King Grass
• High crop yield (90-150 tons/acre/year)
• Drought resistant crop
• Sustainably grown, not a food crop
• Perennial grass
• Not genetically modified
• Not an invasive species
• Needs sunshine, warm weather & rain or irrigation-no freezing
• Fertilizer use is modest
• No pesticide
• Extensive bioenergy test data (2.7 cubic feet biogas/lb GKG)

29. Four 3 MW Generators
29
Biogas generated through anaerobic
digestion will be flow to four 3 MW
Jenbaucher (GE) biogas generators.
(Four generators allows for rotation with
one spare available at all times.)
Generators will produce 3.9 kW per 1
cubic foot per minute of biogas at 42%
efficiency, 57% methane, and 550
BTU/ft3
Approximately 2,100 cubic feet per
minute (cfm) of biogas will produce 8.5
MW to cover WAPA power and parasitic
load
The Generators contain carbon filter gas
treatment, dehumidification system for
moisture removal of biogas, and H2S
filter media.
Jacket water will be used to heat
feedstock prior to anaerobic digestion
Emissions from the generator will be less
than 250 tons/year for all constituents.
30. Power Purchase Agreement (PPA)
30
Tibbar’s PPA/Interconnection Agreement was fully executed by the USVI
WAPA on 7/24/13
The PPA is for 7 MW over 25 years with a 5 year option
The Commencement of Operations is June 30, 2015
Tibbar’s project is the only proposed biomass renewable energy project in
the U.S. Virgin Islands.
Tibbar has also obtained Qualified Facility (for Small Power Generation)
approval from the USVI Public Services Commission.
32. Project Benefits for the VI Department of Agriculture
32
Tibbar will develop a water harvesting program with
multiple ponds on VIDOA land managing nearly 60
million gallons of run-off water.
The community gardening program will reap the
benefits from Tibbar farming operation through
shared irrigation water and organic fertilizer leading
to more consistent and higher yields at community
farms.
In addition, Tibbar will provide tillage services to
local farmers eliminating the current back log.
33. Additional Benefits to the Dept. of Agriculture
33
The USDA cut the DOA hay program grants in 2012. Today it
is challenging for the DOA to produce hay for all 3 islands and
the program is at risk.
Tibbar will take over this commitment and supply the 1000
round hay bales per year for distribution through the DOA
34. Project benefits for VI Waste Management
Authority (WMA)
34
Tibbar’s biogas facility provides an alternative outlet to
landfilling for several of WMA’s waste streams including:
Fats Oils, and Greases (FOG)
Food Waste
Bio-solids
Using these streams as a feedstock for anaerobic
digestion is common practice in Europe
Tibbar’s agricultural operations provides a sustainable
outlet for the WWTP effluent as irrigation water.
35. USVI Governor’s Visit to Denmark
35
On March 13, 2013 Governor John P. de Jongh, Jr.
met with Tibbar’s partner, Renew Energy, to discuss the
biogas project. The visit was part of the Governor’s
Economic Development Tour to promote business
opportunities in the USVI.
37. Overall Project Sustainability and Economic Benefits
