The Kerala State Electricity Board Limited (KSEB) has announced plans to set up a minimum of about 500 MW of solar PV capacity by the year 2021 under the state’s Soura Project.
Under the project three different schemes will be offered to the consumers. In the first two schemes, KSEB will bear the expenses related to solar panel installation and maintenance. As per first scheme, consumer will get 10 per cent of the total produced electricity free of cost whereas in the second scheme consumer will get any quantity of electricity produced at a fixed rate. The third scheme involves consumers investing into the solar power systems. Such consumers would be able to use the entire energy generated at their roof tops and will be entitled to sell the generated solar power completely or partially to the KSEBL. KSEB plans to complete the installation of the panels between January 2019 and March 2021.
Three models of roof top solar projects are planned as part of Soura for achieving 500MW solar capacity addition:
- MODEL-1: Kerala State Electricity Board Limited & ANERT will utilize the rooftop and land of willing consumers for installing solar plant. The energy generated will be fed into the grid for a period of 25 years and a fixed percentage of generation will be given as the incentive/lease rent to the premises owner for his own use. His monthly/ bi-monthly electricity bill will be reduced to that extent. Example: Consider monthly usage of the premises owner as 100 units and the monthly generation from the solar plant installed by KSEBL as 200 units. If the percentage allotted for own consumption of premises owner is 10%, he is entitled to use 20 units (10% of 200) at no charge and his electricity bill will be for 80 units only (100 – 20). In this model premises owner does not incur any cost of solar plant installation.
- MODEL – 2: In this model also the consumer does not have to incur any cost of solar plant installation. Instead KSEBL/ANERT will install rooftop or ground mounted plant in consumer premises and the energy generated will be sold to the consumer for 25 years through PPA, as per his requirement at a fixed tariff. The O & M will be done by KSEBL. Example: Consider the monthly consumption of the consumer as 300 units and the solar generation as 200 units. If the tariff for solar power is fixed as say, Rs. 5 per units, it will remain same for 25 years without any escalation. The monthly bill of the consumer will be = 200 x 5 + 100 x tariff applicable on the date of billing.
- MODEL -3: The consumer will be the investor and KSEBL/ANERT will setup the solar plant for the consumer and excess energy if any after the consumption of consumer/ plant owner/ will be fed into KSEB’s grid at predetermined unit rate. If such surplus energy is available, KSEB will pay for such energy at a pre-determined tariff. KSEB can take up maintenance of the plant during the operation period, based on requirement of consumer.
