I submitted a request for the power spot at my village because I’m living in a rural village and nearest power spot that available for me is around 10km far from me
Welcome to the forums 
it is not possible to submit a request for a powerspot explicitly. What you can submit is wayspot requests, which - if accepted - might get used in Pokemon Go as a pokestop, gy,m or powerspot.
Every wayspot must meet criteria and follow eligibility rules.
Please have a look at these for understanding what makes a good wayspot.

Acceptance https://wayfarer.nianticlabs.com/new/criteria/acceptance
Rejection https://wayfarer.nianticlabs.com/new/criteria/rejection
Also Wayspot Criteria — Wayfarer Help Center
Generally, a shop will not meet criteria as its purpose is not social, exercise or exploration.
