Dynamic growth under the umbrella of a stable parent company Turnover 2017 EBIT 2017 Employees €16.1 billion Euro €171.3 million Euro 17,550 Founded Core segment Locations Agriculture, energy, More than 3,000 1923 construction locations in 40 countries 5

The way ahead lies in a sound energy mix Solar energy Bioenergy Wind energy We have brought solar farms with We have already developed and set up We provide experience in an output of more than 600 MWp 34 biogas and biomethane plants with the development and realization of wind farms with an installed capacity to the grid. We have supplied our a total biogas output of approx. of over 1,300 MW . installers with solar modules with 110 MW . a total output of 1,500 MWp . In excess of 3,000 MW under our operations management 6

Adding global experience to local knowledge in Asia Pacific BayWa r.e. is joined by one of the most experienced teams in the Asia Pacific region. BayWa r.e. presence Markets under development · With offices in Singapore, Bangkok, Tokyo and Perth, BayWa r.e. has significant local market experience · Full on-the-ground technical, commercial and financial capabilities · Combined with the financial support of a strong parent company, BayWa r.e. becomes the most complete platform to deliver results across the Asia Pacific region 8

Our services for successful energy projects In addition to the development and implementation of our own projects, we also build turnkey projects as a third party service  Green field project planning  Turnkey construction  Site analysis and assessment  Project management  Securing land and planning  Project finance permissions 2,000 MW We have already set up and commissioned 34 biogas and biomethane plants with a biogas output In further project rights have of about already been secured in Europe, 110 MW. America, Asia and Australia. To date, we have developed and realized wind We have successfully put farms with an installed output of 600 MWp 1,300 MW. of solar energy into the grid. 9

Why Energy Storage? 10

Why energy storage? Worldwide renewable and non-renewable power capacity additions The global trend is towards much more PV and wind Source: IRENA (2017), REthinking Energy 2017: Accelerating the global energy transformation. International Renewable Energy Agency, Abu Dhabi . 11

Why energy storage? With wind and solar, new power system will be based on two technologies that completely change the picture Gross electricity generation of Electricity generation and consumption renewable energies 2000 - 2035 in a sample week 2023 G Specific W characteristics of Wind and Solar PV 1 Variable High 2 capital costs Very low 3 variable cost AGEB (2015a), BNetzA (2014), BNetzA (2015b), own Fraunhofer IWES (2013) calculations 12

Why energy storage? Flexibility is the paradigm of the new power system – baseload capacities are hardly needed in longer future => New coal power plants need to get flexible! Electricity generation and consumption in a sample week with 50% RES share Key flexibility options Flexible fossil and bioenergy power plants (incl. CHP) Grids and transmission capacities for exports/imports Demand Side Management Storage technologies (Batteries, Power-to-Gas) Integration of the power, heat and transport sectors (power-to-heat, electric cars) Own calculations on basis of Agora Energiewende (2015b) Source: AGORA Dr. Patrick Graichen; Insights from Germany’s Energiewende, Berlin 2016 13

Why energy storage? Future of energy systems – towards a new paradigm? Smart local grids, linking a diverse set of distributed resources across different sectors. Why energy storage? • increased distributed energy resources increases grid variability. • Baseload capacities needed for grid flexibility.  sustainable solution to emerging energy problems! 15
