The following article is the fruit of a thorough reflection in the field of power productive plants on the objectives to achieve for fitting with the best criteria of sustainable development. It is obvious that the Total Cost of Ownership (TCO) of energy production plants would soon become the standard.
L'article ci-après est le fruit d'une réflexion approfondie sur les objectifs à atteindre dans le domaine des centrales de production d'énergie pour répondre parfaitement aux meilleurs critères du développement durable. Il est évident que le coût total de possession des centrales de production d'énergie deviendra bientôt le standard.

SPP = 1 / MDP
MDE = MDP / ( 8.766 * AVF * DUR )
Exemple:DEF = (280 - 0.030) / 280 = 100 %
These economies of scale began to fail in the late 1960s and, by the start of the 21st century, central plants could arguably no longer deliver competitively cheap and reliable electricity to more remote customers through the grid, because the plants had come to cost less than the grid and had become so reliable that nearly all power failures originated in the grid. Thus, the grid had become the main driver of remote customers power costs and power quality problems, which became more acute as digital equipment required extremely reliable electricity. Efficiency gains no longer come from increasing generating capacity, but from smaller units located closer to sites of demand. For example, coal power plants are built away from cities to prevent their heavy air pollution from affecting the populace. In addition, such plants are often built near collieries to minimize the cost of transporting coal. Hydroelectric plants are by their nature limited to operating at sites with sufficient water flow. Low pollution is a crucial advantage of combined cycle plants that burn natural gas. The low pollution permits the plants to be near enough to a city to be used for district heating and cooling.SFC = ( 1 - REN ) / ( LHV * EFF )
avec LHV (low calorific value - kWh/kg)
Pour le pétrole: LHV = 11,628 kWh/kg. Avec un rendement de 37% et un pourcentage d'énergie renouvelable de 70%, il vient: SFC = (1 - 0,7) / (11.628 * 0,37) = 0.07 kg/kWh
MDF = MRF * MDE
Exemple :SEF = SPF * 8766 * AVF
Repayment period = DUR / EDF
