4. Northern Power Systems: Global Footprint

Over 400 NPS Systems Installed Worldwide Including
2.1 MW Turbines With Our Brazilian Partner WEG
 Strong installed base in western countries
 Poised to take distributed wind to emerging markets
Several regions across the globe are facing difficult conditions:
 High power costs
 Weak grid infrastructure
 Desire for more sustainability and independence
Distributed Generation should be part of the Solution

5. Why Choose Wind for Water Treatment?
Why choose wind:
 Electricity demand for water desalination is said to
raise by...
 300% btw. 2007 and 2030 in the MENA region (IRENA)
 9% globally p.a. during the next years (IRENA)
 Main regions for water desalination are MENA, USA,
with India and China increasing in importance. All of
these regions have RES-E targets, many rely on
electricity or Diesel import.
 1 m3 classically requires 2-2,5 kWh (in case of
reverse osmosis) or 1-2 l Diesel. If at a cost of 1 USD
per liter as in many geographies, 1 m3 costs 1-1.5
USD in energy vs. 0.3-0.5 USD if ran by NPS 100 (@
wind speed of 6m/s, before financing and taxes)
 If combined with Solar PV, wind power allows for
constant power supply both day and night, summer
and winter
 Desalination can substitute costly storage often
required with fluctuating RES-E: Desalinated water
itself can be stored (i.e. produced in alignment with
RES-E fluctuation)
 On-site distributed wind brings significant value to an
on-site energy mix, and can complimented with
energy storage to help absorb excess electricity to be
dispatched on site during times of high demand when
wind may not be blowing.

6. Why Choose Northern Power Systems?
 Proven wind turbine solutions - leading permanent
magnet, direct-drive technology provider in the distributed
energy market driving niche-penetration in the multi-MW
utility scale industry
 Grid integration technology for today’s needs.
Advanced grid modeling and systems integration
experience lead to cost efficient sustainable energy
solutions
 Introducing NPS 100, the optimal sized wind turbine
 Ease of Integration – our wind turbines are designed to be
“inverter-connected” and easily integrated through advanced
power electronics into the overall balance of system
architecture
 Increased Annual Energy Production (AEP) – Our PMDD
technology maximizes energy capture, outperforms
conventional gearbox designs, and reduces maintenance
costs
 Perfect Size – the NPS 100 wind turbine requires a small
footprint in order to be integrated into any desalination or
water treatment project. Its low height profile (< 50 m) and
quiet operation ease permitting processes
 Easy transportation: 2 12m containers include all parts of a
NPS 100 and are thus easily transported and installed to and
at most sites

7. Case Study: Water Treatment and Wind in Germany
7
 100 kW size allows for modular sizing of the power plant in dependence of local power prices,
capital situation of the operator and risk appetite
 Up to 95% of self-consumed wind power can be consumed directly for this specific researched
case if 2 turbines are installed. This does not require any storage nor controls and offers for
each kWh the value of the retail price / kWh incl. all taxes and charges, in Germany above 20
EUR-cents / kWh. Depending the country, the excess power can be fed into the grid either for
a Feed-in tariff OR for a Premium Feed-in OR for the normal wholesale power price
 While 1-3 x NPS 100 «only» cover 20%-50% of total power consumption at the investigated
site during the course of a year, a larger project would yield more excess power to the grid
having lower value than offset power demand from the grid
 Adding Solar could increase the share of RES-E as part of the complete load dramatically

8. Wind + Solar = Constant Power Supply
Reliable Power Supply – by combining wind and solar PV allows for
constant power supply both day and night, summer and winter
Increased System Capacity Factor – the overall water treatment
facility’s capacity factor is increased to meet overall site requirements and
maximize site performance
Increased System Annual Energy Production (AEP) – together wind
and solar complement each other by reducing times of intermittency and
maximizing AEP

13. NPS 100 PM/DD TurbineTraditional Geared Turbine
 Complex, high-speed drivetrain problematic:
5-7% downtime. (Gearbox replacements/7-9years)
High scheduled and unscheduled maintenance
cost – oil, filter, bearing replacements
 Failures of large components require expensive
crane & significant downtime
 Economically infeasible in distributed wind due to
significant downtime and high O&M costs
13
 Simple, low speed drivetrain extremely reliable:
1-2% Downtime
No high-speed wear & tear or gearbox
replacement
 Very high-efficiency … no friction losses and
permanent magnets supply magnetic field
 Direct drive empowers wind generation by
delivering more power, more of the time, at lower
cost
Fundamentally Better than Geared

We would be interested in calculating the business case for your water
treatment or desalination project when reducing power demand from the
and/or Diesel consumption
To help you, we need the following information:
1. GPS coordinates of the site for a first wind assessment using a global database of wind
speeds at any given height OR: Wind measurement data
2. Load profile (ideal: 15 minute values over the course of a complete year)
3. kWh price for power sourced from the grid (or e.g. provided via Diesel GenSets) and yearly
increase expected over 20 years lifetime
4. kWh price for each kWh exported to the grid (if applicable) and yearly change expected over
20 years lifetime
5. Share of equity and debt, with expected interest % for each
6. Other public incentives
7. Profit tax for your project
8. Permitting restrictions (e.g. max. hub height or kW rating for avoiding costly or cumbersome
applications incl. value of savings if hub height or kW rating are met)
