Load Reduction through Solar & Batteries could lower the need for large upfront capital investment for large extra power plants
This whole area of development is just getting started with some exciting possibilities !

Properly incentivised, the utilities could begin to aggregate neighbourhoods of solar + batteries to behave as a single source of load reduction. Batteries could be dispatched as needed to reduce peak demand across the system. In a high grid penetration scenario, this could reasonably lower the necessary capacity from conventional generation sources. In turn, we think it is reasonable to hypothesize that lowered capacity needs from lowered peak demand would simultaneously lower the need for large upfront capital investment in High operating cost peaker plants. This in return will reduce the Tariff for Electricity.
Sri Lanka will definitely need this to reduce the night peak, and postpone new large investment for extra peaking power plants.
CEB must go for very high evening peak Tariff people will soon move to storage batteries, with very low payback period for the battery.
CEB will benefit with no investment building behind the meter Storage. This will be a win win situation.
There's no doubt renewable power generation has made great leaps and bounds lately bringing the cost of power per kW down to competitive levels but what about storing all that energy so as to be available on demand, or even better yet, during peak hours when energy is at it's most expensive. This whole area of development is just getting started with some exciting possibilities !
