  1. 1. ESS SAMSUNG SDI | ENERGY STORAGE SYSTEM Copyright © 2013 Samsung SDI. All rights reserved
  2. 2. Samsung SDI Energy Storage System | What is ESS? Copyright © 2013 Samsung SDI. All rights reserved ESS is short for Energy Storage System, meaning that it can actually store energy and use the stored energy whenever the need arises
  3. 3. Samsung SDI Energy Storage System | What is ESS? As the need for clean energy arises, the need to replace current existing power plants have become a global issue Copyright © 2013 Samsung SDI. All rights reserved
  4. 4. Copyright © 2013 Samsung SDI. All rights reserved What is ESS?
  5. 5. 1 Samsung SDI Energy Storage System | What is ESS? Copyright © 2013 Samsung SDI. All rights reserved ESS compensates for intermittency of renewable energy, such as wind and solar To compensate for wind and sunshine’s variability, energy storage provides stored electricity to the grid and stable power output from renewable energy sources. • Reduces output variability • Improves power quality Frequency ESS Time
  6. 6. 2 Samsung SDI Energy Storage System | What is ESS? Copyright © 2013 Samsung SDI. All rights reserved ESS helps grid system operators maintain constant frequency Energy storage based on Lithium-Ion Battery (LIB) provides reliable and fast frequency response without being subject to fuel prices and with zero emissions. • Fast frequency regulation & ancillary service Frequency Time
  7. 7. 3 Samsung SDI Energy Storage System | What is ESS? Copyright © 2013 Samsung SDI. All rights reserved ESS can be used for curtailment of electricity from renewable energy sources Due to transmission constraints, currently, ever-increasing portion of wind generation is being curtailed. Energy storage is the best option for reducing renewable power curtailment, relieving transmission congestion, and achieving full utilization of renewable energy sources. ESS
  8. 8. 4 Samsung SDI Energy Storage System | What is ESS? Copyright © 2013 Samsung SDI. All rights reserved ESS can be used to defer transmission and distribution network (T&D) upgrades and investment Using energy storage, upgrade to transmission and distribution networks can be deferred by smart management of the local peak demands. • Transmission support • Transmission congestion relief • Area/frequency regulation ESS
  9. 9. 5 Samsung SDI Energy Storage System | What is ESS? Copyright © 2013 Samsung SDI. All rights reserved ESS enables commercial & residential owners to cut energy costs Electricity stored during off-peak time can be used during on-peak hours so that home/ commercial owners can cut peak demand and electricity cost. ESS integrated with PV can maximize consumption of solar energy by using electricity stored off-peak. • Energy cost saving • Demand management • Self consumption of solar power Energy Consumption Day Night
  10. 10. Samsung SDI Energy Storage System | Types of ESS? Copyright © 2013 Samsung SDI. All rights reserved Types of ESS? ESS is a technology that has been adopted for many years. The technology used behind ESS includes Compressed Air Energy Storage (CAES), Flywheel, Pumped Hydro and batteries. Category BATTERY PUMPED HYDRO FLYWHEEL CAES High Energy Density, larger operating temp. range Hight Capacity, Long Lifespan Short Charge Time High Capacity, Long Lifespan Significant Negative Effect on Environment Highly Inflammable Geographical Constraint Type characteristic
  11. 11. Samsung SDI Energy Storage System | Types of ESS? Copyright © 2013 Samsung SDI. All rights reserved Types of BATTERIES? Currently battery has become mainstream as technologies such as NaS, Lithium-ion, Lead-acid and flow batteries have begun to participate in various worldwide projects. Samsung SDI specializes in manufacturing Lithium-Ion Battery (LIB) which is high in energy density, voltage, discharge rate and lifespan. In addition, LIB is eco-friendly and has no memory effect, making it optimal for long term use. Category LITHIUM-ION BATTERY (LIB) LEAD-ACID NATRIUM-SULFUR BATTERY(NaS) High Capacity, Long lifespan Low Cost Low Cost Low Capacity, Not eco-friendly Not eco-friendly, Highly Inflammable Type characteristic
