( 1 ) "owned and leased capability" is the dependable load carrying capability as demonstrated under actual operating conditions based on the primary fuel ( assuming no curtailments ) that each station was designed to utilize .
entergy's load and capacity projections are reviewed periodically to assess the need and timing for additional generating capacity and interconnections .
these reviews consider existing and projected demand , the availability and price of power , the location of new loads , and economy .
peak load in the u.s .
utility service territory is typically around 21000 mw , with minimum load typically around 9000 mw .
allowing for an adequate reserve margin , entergy has been short approximately 3000 mw during the summer peak load period .
in addition to its net short position at summer peak , entergy considers its generation in three categories : ( 1 ) baseload ( e.g .
coal and nuclear ) ; ( 2 ) load-following ( e.g .
combined cycle gas-fired ) ; and ( 3 ) peaking .
the relative supply and demand for these categories of generation vary by region of the entergy system .
for example , the north end of its system has more baseload coal and nuclear generation than regional demand requires , but is short load-following or intermediate generation .
in the south end of the entergy system , load would be more effectively served if gas- fired intermediate resources already in place were supplemented with additional solid fuel baseload generation. .
