3. Who We Are
 TERI was established in 1974, with the initial focus on documentation and
information dissemination. Research activities were initiated towards the end of
1982.
 TERI, being the largest developing-country institution working towards
sustainability, is devoted to formulating local, national, and global-level strategies to
address critical issues.
 Towards this end, regional centres have been established in Bengaluru, Goa,
Guwahati, Mumbai, and the Himalayas. Affiliate institutes were also set up globally:
 TERI-NA, Washington, DC, USA,
 TERI Europe, London, UK,
 Japan,
 Malaysia,
 The UAE.
 A research base has been established in Africa to provide technical assistance and
facilitate exchange of knowledge amongst the communities in various states and
countries.
 TERI is now poised for future growth driven by a philosophy that assigns primacy to
enterprise in government, industry, and individual actions.

India’s Pledge: Intended Nationally Determined
Contribution(INDC) post 2020
Highlights
 To reduce the emissions intensity of GDP by 33% to 35% by 2030
below 2005 levels
 To create an additional (cumulative) carbon sink of 2.5-3 GtCO2e
through additional forest and tree cover by 2030
Renewable energy
 Greater use of renewables mainly through solar and wind power and shifting towards
supercritical technologies for coal based power plants.
 To achieve about 40% cumulative electric power installed capacity from non-fossil
fuel based energy resources by 2030 with the help of transfer of technology and low
cost international finance including from Green Climate Fund (GCF).

o Electricity produced through solar is directly consumed
o Extra electricity generated on holidays can be feed back
to grid
o Cost of Electricity is increasing year-on-year
o Subsidy is available from central government
o Payback period is very less i.e. around 5-7 years

Self Owned- CAPEX Model
 Consumer is the owner of the solar plant
 Consumer need to pay up-front cost for the solar plant
 In CAPEX mode the consumer get the payback of the
investment in 5–7 year
 Profit making industrial and commercial consumers
are eligible to avail accelerated depreciation benefits

 No upfront investment is required for installation of
solar plant in RESCO model
 Consumer will sign a long-term contract (25 years
PPA) with the solar developer
 The ownership of the solar plant will remain with the
power plant developer
 Consumer is not eligible to avail accelerated
depreciation benefits
 In Surat the developers can offer for a RESCO price of
around 5.8–6.8/kWh for next 25 years (SECI/GEDA
will discover the price)
