Problem

100\,\text{MW}

of electrical power is transmitted through lines having an effective resistance of

10\,\Omega

. Find the annual energy saved (in \text{MWh}) when the transmission voltage is raised from

33\,\text{kV}

132\,\text{kV}

. Assume continuous full-load operation for

365

days. a)

3.8\times10^{5}\,\text{MWh}

1.5\times10^{5}\,\text{MWh}

7.5\times10^{5}\,\text{MWh}

6.0\times10^{5}\,\text{MWh}
