Dholera Solar Park is a 5GW solar power project being developed in two phases in Dholera village, approximately 80km from Ahmedabad, Gujarat, India.
Dholera solar
park is a 5GW solar power project being developed in two phases in Dholera
village, approximately 80km from Ahmedabad, Gujarat, India.
Gujarat Urja
Nigam Limited (GUVN) has been developing the project through public-private
partnership (PPP).
The company is
working with Gujarat Power Corporation (GPCL), Gujarat Electric Transmission
Corporation (GETCO), Solar Energy Corporation (SECI) and Power Grid Corporation
of India (POWERGRID) for the implementation of the project.
The first
1GW-phase is being developed with an investment of Rs5bn ($695m) by GPCL, while
the second 4GW-phase will be developed by SECI with an estimated investment of
Rs20bn ($2.7bn).
The solar park
is a part of the government’s plan for establishing India’s first world-class
greenfield Dholera smart city project
announced in 2009. It also supports the government’s aim to produce 175GW of
clean energy by 2022.
The Ministry of
New and Renewable Energy approved the project in May 2018, while conditional
approval for the first phase of development was received in February 2019.
Dholera solar park location
Dholera solar
park will be located at a Coastal Regulation Zone (CRZ) type 1B land within the
Dholera Special Investment
Region (DSIR), situated along the Gulf of Khambhat region, Gujarat.
Spanning 920km²,
DSIR encompasses 22 Gujarat villages and will be developed by the
government-constituted body Dholera
Special Investment Regional Development Authority (DSIRDA).
It is
well-connected by road, rail, airport and seaport and lies close to the
megacities of Gujarat, including Ahmedabad, Bhavnagar and Vadodara.
The site has a
high coastal vulnerability index as it is situated in a low-lying area at the
delta of five rivers, Padaliyo, Lilka, Utavali, Sukhbhadar and Ker. It is an
inter-tidal and highly eroding area with corrosive air.
Dholera solar park details
The solar park
will cover a total area of 8,595ha, which has been divided into 11 blocks with
27 plots in each block.
Each plot will
have 100MW, 160MW and 200MW capacity blocks.
Solar
photovoltaic modules based on poly-crystalline silicon technology will be
installed at the solar park.
The modules will
be mounted on fixed and grouted plain cement concrete (PCC) foundation and
installed at a pedestal height between 380mm and 450mm due to the tidal and
flood effect. The silicon rubber edge sealing will protect and support the
module.
The maximum
module power rating will reach just under 280Wp, while the photoelectric
conversion module efficiency will be more than 15%. The junction boxes will be
made of thermoplastic.
Power Transmission from Dholera Solar
Park
The power
generated by the Dholera solar park will be transmitted through a 49km-long,
33kV underground cable network, including high and low-voltage lines. The cable
network will be built across the park to transport the generated power from the
solar panels to pooling substations and into a 33kV / 400kV substation.
The power will
step-up twice from 33kV to 200kV at the pooling substation and then to 400kV at
Power Grid Corporation of India Limited (PGCIL) grid substation. The substation
and pooling station will be constructed at an elevated height to avoid flood damage.
GETCO will
evacuate the power generated in phase one, while the power generated in phase
two will be evacuated by POWERGRID.
Infrastructure Details
Radio masts and
towers will be installed for holding the telecommunication antennas that will
provide integrated telecommunication services.
Canals will be
developed to off-take water from the Narmada River to the power plant. An
underground water pumping facility, ground service reservoir and water
transmission pipeline will be constructed to distribute the water through the
site.
