How power is generated, moved and priced.
Generation, demand, wholesale markets, transmission, distribution and grid reliability — explained with evidence.
Electricity covers the full chain from power station to meter: how generation is dispatched, how demand moves through the day and the seasons, and how wholesale prices are set in markets run by grid operators. These mechanics decide which plants run, which investments pay back and what households and businesses ultimately pay.
Coverage here focuses on reliability, capacity adequacy and price formation. We explain marginal pricing, scarcity events, capacity markets and the growing role of weather-dependent generation. When a market posts a record price or a reserve shortfall, we try to explain the cause rather than just the headline. Start with the guides below if terms such as megawatt, capacity market or demand response are new.
