ELECTRICITY GEN,T&D - TREND MIGRATION FROM CENTRALIZED TO DISTRIBUTED.( MAIN FRAME TO PC)

UTILITY GRID UNSTABLE, SURGY, NOISY- FR OF ELECTRONIC DEVICE MAINLY ATTRIBUTABLE TO GRID INSTABILITY.

GRID INSTABILITY POINTS TO ENERGY SHORTFALL.

CONCEPT OF THIS PROJECT - ROOF TOP NANO PLANTS

EVERY ROOF – SELF SUFFICIENT TO ITS ELECTRIC NEEDS. 24X7.VIABLE,RELIABLE,RENEWABLE _ EXCESS ENERGY PUMP BACK TO UTILITY ,WHILE GRID IS ON _ WHILE GRID IS OFF, SERVE INTERNAL NEEDS THRO' SOLAR ; EXCESS TO NEIGHBORHOOD THRO' MICRO GRID, BATTERY CHARGE, HEATING_ IN NIGHT, SERVE THRO' SOLAR ENERGY CHARGED BATTERY INVERTERS



Customer Wishes

UNINTERRUPED 24X7 ELECTRICITY

NO FLUCTUATIONS

EXPENSIVE DEVICES LIKE APPLIANCES, TV , MULTI MEDIA GADGETS TO BE PROTECTED AGAINST GRID SURGE

GREEN SAVVY

INCREASINGLY ITCHY ,INTOLERANT WITH UNRELIABLE, UNSTABLE UTILITY GRID.

SOLARSAN–NRT- NANO ROOF TOP – WAY FORWARD

RENEWABLE ENERGY POLICIES ARE IN PLACE. GOOD STARTING POINT.

NANO ROOF TOP LENDS ITSELF FOR QUICK MASS IMPLEMENTATION.

- ALL ASPECTS TECHNICAL, FUNDING, ...NEED TO DRAW UP PROCEDURES TO KEEP PACE. NO NEED FOR LAND APPROVAL,FOREST DEPT etc... ONLY OWNER, BESCOM PPA .

NEED FOR AGENCY LEVEL COMMON UNDERSTANDING. BESCOM, KERC, KREDL,MNRE ESPESCIALLY FOR CATEGORY 2 GRID CONNECTIVITY., FUNDING TYPES

HOW DO WE UPSCALE TO MASS IMPLEMENTATION?

BESCOM ONE POINT WINDOW . RENEWABLE ENERGY DEPARTMENT?

PPA PROCESS - IN PUBLIC DOMAIN.

ENERGY MONITORING POINTS, SAFETY AUDIT,CODE COMPLIANCE etc..

PPA PROCESS- CENTRAL FUNDING/ STATE FUNDING/ PRIVATE FUNDING

NEED FOR SEPARATE PPA PROCESS FOR EACH ROUTE TO ACCELERATE IMPLEMENTATION
