A workshop on “Market Assessment and Characterization of Energy Battery Storage Technology” was conducted by the IGEF-SO on 13th January, 2017 in Mumbai. The special session was part of a conference event under Energy Storage India 2017 which took place at Nehru Centre, Mumbai, India from 12 – 13, January 2017. The workshop was attended by 50 participants and stakeholders from sectors like policy-makers, implementation agencies, consulting firms, financing institutions, project developers etc. The speakers at the Workshop were from companies/ institutions like IGEF-SO, KFW, Fraunhofer ISE, SECI, Steag, Qinous, Autarsys, SMA, and BVES.
The major discussion points were
The workshop started with an introduction about IGEF-SO and Subgroup-2- Renewable Energies. KFW shared its German experience of financing two programs in energy storage and role in India with updates of Indo German Solar Energy Partnership and Access to Energy line with IREDA. Fraunhofer ISE from Germany explained the global price development curve of Lithium-ion battery and its combination with PV solar systems to achieve high net present value. Another case of PV diesel hybrid system for Uganda was discussed where reduction in massive diesel cost through reduction in consumption were noticed. SECI presented the upcoming solar parks capacity approved by the government and the need for storage systems to smoothen the fluctuations. SECI also mentioned about the upcoming pilot tenders for storage solutions.
Steag shared German experience of 90 MW battery storage installations for Primary Frequency Control. Currently there are no similar requirements in India, but these kinds of requirements are expected in future when the share of Renewable Energy injection will increase in the grid. Quinous and Autarsys shared their installation experience and the need for energy storage systems in container sizes.
The major discussion points during panel discussions were on the upcoming demonstration projects especially in India, viability of battery storage, life cycle of batteries, disposal mechanism and its integration with diesel set to offset diesel consumption. The life tenor of Lithium ion battery was mentioned to be around 7-8 years. SMA mentioned that they have installed 10-15 hybrid systems with PV Solar integrated with diesel Genset and the factory grid connection in Southern India. When there is a power failure, then this system synchronises with Diesel Genset load and reduces the diesel consumption and during grid connection, they synchronize with grid and reduce the peak consumption from grid. It was also mentioned that once the forecasting and scheduling penalties for renewable energy developers are imposed on strictly, the battery storage projects will grow in size.
