He [K Sivan] said the first test-launch of Small Satellite Launch Vehicle (SSLV) or mini-PSLV and a technology demonstrator test of the reusable launch vehicle (RLV) will also happen next year.
Not sure, but maybe this is for the SSLV launch:
Also, FLP may not be occupied by SSLV as this rocket is on-demand and can be stacked up at the very end. I believe, they will use the new buildings developed as part of PIF project.

I believe, they will use the new buildings developed as part of PIF project.What is the PIF project?My assumption was that FLP needed substantial alterations to perform the first SSLV launch campaign, as well as extensive testing. I also assumed that this work would preclude other launches until after the first launch.What is the status of this work?
Multiple sources in ISRO said on Thursday SSLV-D1 is targeted to be launched towards the end of March or early April -- most likely in the first month of the financial year -- though no firm date has been set so far.
According to sources, GISAT-1 will be followed by the maiden flight of Small Satellite Launch Vehicle, ISRO's compact launcher, likely in April.
Did the static fire occur?
S85 (First stage motor) static test failed due to design issuesQuoteThe static test of first stage solid motor (SS1) of ISRO's Small Satellite Launch Vehicle (SSLV) -- a new-generation compact rocket -- was not successful, according to sources in ISRO. "Oscillation was noticed after 60 seconds into the test and nozzle was blown out near the bucket flange where it's attached with the motor at around 95 seconds", sources in the Bengaluru-headquartered space agency said.QuoteIt was supposed to be tested for a total duration of about 110 seconds, officials said.QuoteNew motor has to be static tested on the ground to prove its performance. If it is successful, one more of the same configuration is tested again for acceptance.If both are successful, no more ground test is required and third motor of the same configuration will be accepted for flight", an ISRO official said.Source: https://economictimes.indiatimes.com/news/science/static-test-of-first-stage-solid-motor-of-indias-mini-rocket-sslv-unsuccessful/articleshow/81653164.cms

The Indian Space Research Organisation is gearing up for its first developmental flight, a new-generation compact rocket which is scheduled to be launched in the fourth quarter of the year 2021. Hence, according to the officials, the Indian space agency is all set to test the solid-fuel motor of the small rocket which is under development.
The official also said the space agency is planning to fly the small rocket -- Small Satellite Launch Vehicle (SSLV) -- before the end of this year itself with an Indian earth observation satellite.

As many arterial roads in Nellore have to be closed due to the floods, Isro is not able to finalise its launches.Isro chairman K Sivan told TOI, "We have been working on three launches, including the small satellite launch vehicle (mini-PSLV) launch, before the year ends. But due to heavy rain and floods in Andhra, we have to reassess the situation... We can decide on the three launches only when the flood situation improves."

SSLV launch soonThe new launch vehicle, SSLV, is designed to reduce the cost of small satellites weighing up to 500 kilograms. This is a launch vehicle with a lot of commercial potential. All three stages use solid fuel. The latter also has a speed control engine that uses liquid fuel. All important experiments are done. The first test launch of the rocket will take place from Sriharikota in the first half of this year.
