Advance Electrical Design & Engineering Institute Electric power transmission is the bulk transfer of electrical energy, a process in the delivery of electricity to consumers. A power transmission network typically connects power plants to multiple substations near a populated area. The wiring from substations to customers is referred to as electricity distribution, following the historic business model separating the wholesale electricity transmission business from distributors who deliver the electricity to the homes.

Advance Electrical Design & Engineering Institute Potential of solar energy What is Photovoltaic (PV)? Photovoltaic means turning daylight directly into dc electricity Done by photovoltaic cells (PV cells), assembled into PV modules There are no moving parts
There is no 'fuel', apart from daylight The modules need no maintenance In principle, almost indefinite lifetime
Central power plant Offices PV power plant
PV works with both direct sunlight and indirect daylight (more light = more power)
Houses
Storage
CHP
Microturbines Fuel cells
