3 About Nidec Corporation FY15 sales by product group The genisys of an industrial player 2009, Nidec Techno Motors has been incoporated for small motors for commercial and industrial applications 2012, Nidec acquires US motors from Emerson (USA), motors and controls for industrial, residential and commercial applications 2013, Nidec acquires Ansaldo Sistemi Industriali SpA (Europe), generators, drives, power quality, and industrial automation 2013, Nidec acquires Avtron Automation (USA), automation equipment for heavy industry 2015, Nidec assigns ASI role as leader of the Industrial Systems platform: NIS February 2017, Nidec acquires Leroy Somer (France) and Control Techniques (UK) Workforce: 140,000 Market capitalization: $25B USD Goal: become the number one brand in industrial motors & drive solutions 3/16

4 Nidec ASI is a one-stop-shop Based on our proprietary technology in LV/MV Drives, PMS, EMS 4/16

5 Leading edge technology for renewable energy Brand new 1500V Power Conversion Systems with more than 1GWp for PV, microgrid and battery energy storage solutions worldwide PV Plant Hybrid/electric propulsion 5/16

6 World Leader in Battery Energy Storage & smart microgrid solutions Norway 1,6 MWh Mexico 238 MW UK* 59 MWh France 24.5 MWh France 24.5 MWh Germany 140 MWh Italy 216 MWh** Japan 6 MWh F. Guiana 5 MWh Marocco 30 kwh Maldive 1.5 MWh Chile 752 kwh Mayotte 50 kwh 450MWh of Battery Energy Storage solutions (BESS) installed *41 MWh under construction ** In some projects the SoW was PCS supply 6/16

7 STEAG PROJECT Germany: Steag project The challenge Primary frequency regulation (PFR) to the grid to ensure stability Scope of supply: EPC for 6 BESS for 15 MW/ 23MWh Net Voltage: 10 KV Total Peak Power: 90 MW Total Capacity: 138 MWh Technology Optimized configuration: 1.5 MW/2.3 MWh in 40 container Li Ion Batteries 7/16

8 PFR a simple concept Each week the German national grid issues a tender for PFR services with 1 MW min size. With 52 bids/year the service provider must be fast and competitive.that s why STEAG chose BESS and NIDEC 8/16

9 Project Challenges Meeting the stringent German Grid Codes Minimizing losses to maximize profit Meeting Health & Safety regulations Deliver the entire project 6 sites in less than 12 months 9/16

10 Performance Project Challenges The German Grid Code requirements Automatic and complete activation within 30 sec in case of frequency deviations Proportional regulation with droop (Statik) as proportional gain Typical value 0,4% with 200mHz / -200mHz Frequency band to be covered 49,8 Hz.50,2 Hz Deadband 50 Hz ± 10 mhz (49,99 Hz. 50,01 Hz) Time period to be covered per single fault at least 15 min Continuous full call of primary control in prequalified technical units with capacity limitation for at least 30 minutes The primary control must be provided throughout the entire offer period (one week) 10/16

11 Minimizing losses from auxiliaries Our challenge a) Heat mitigation Vs Guaranteed PeGu b) Cooling systems cons Further heat generation Energy consumption The solutions 1. External cooling device(chillers) w free cooling mode by fans 2. External and sealed oil trafo(natural cooling) 3. Trafo designed for no load losses 4. Smart State of Charge(SoC) and State of Health (SoH) management through algoritm to optimize performance of the system 5. Simulation of SoC during eng phase 11/16

12 Health & Safety OUR CHALLENGE: Being the first often means having to find solutions to problems that have never been faced before. On the market today there are no containers that are fully compliant with fire safety regulations Working with safety experts we identified a reliable innovative solution to solve the problem installing cement fire containment walls between the trafo and containers. 12/16
