GEPL – Many Firsts
 1st Independent Power Trading company in India, even before the first
electricity trade in the world
 Executed 1st inter – state contract for power trading in India in 1992
 1st to conceptualize and launch a power exchange in India – India Electron
Exchange (IEE) in 2004, in association with the Govt. of Goa, ICICI Bank
and TPT Inc, USA
 1st to successfully trade Wind Power under Open Access
 1st to sale Solar Energy to Third Party under Open Access mechanism
GEPL’s Energy Storage
Milestones/Objectives/Path
•
Extensive study of various energy
storage
technologies
and
applications

Regulatory
and
Policy
recommendations, (educating) to a
number of state agencies and
utilities on energy storage
•
Financial analysis of energy storage
solutions
•
Technology Agnostic with focus on
getting the best fit solution for
energy storage requirements
•
International Collaborations
Association with Younicos
Younicos provides integrated Energy Storage Systems combining
• Track record and experience: Large installation experience of more than
97 MW across the globe and MW-scale micro-grid test center
• Technology agnostic storage system design and cell-level battery
knowledge: Use the battery technology that fits best your application
• Advanced storage control software: Run several storage services
simultaneously and fully automated.

Renewable Energy Impact
• Infirm
• Unpredictable
• Unscheduled generation
• Grid instability – frequency and voltage variations
• Transmission constraints - excess generation needs additional
transmission capacity or else it needs to be curtailed resulting in waste of
renewable power. Else thermal power plants need to be laid off to
accommodate RE power.
• Inefficiency of power system, because of backing down of thermal power
plants
• Possibility of the California Duck Curve phenomena
