Electricity generation 1. The power plant 2. Three phase power p = (3/V 3. Transmission substation where transformers step up voltage for long- distance transmission. Typical stepped up values 155kv to 765kv. 4. Stepping down in stages at transmission station to about 7200V for  residential. 5. At the house, a transformer transforms one phase power to 240v for home  use. Obstacles to transmission lines 1. Aesthetics 2. Possible health issues 3.  Water bodies and other geographical things to go around 4. Right of way eg through Indian land. Reducing the 10% losses. 1. Putting generators closer to load. 2. Distributed generation eg using fuel cells. Distributed generation is energy  generation from many different sources eg fuel cells. Low maintenance,  low pollution, high efficiencies. Demand response  (DR) is a ‘when-called’ resource to reduce highest system  peaks and add reliability in times of system emergencies. Eg, laundry during off- peak hours, turning off AC during peaks, with incentives. This is different from
