Record Wind Generation Tests Texas’s Transmission System

Wind power generation in Texas is growing so quickly that it is testing the limits of the state’s electrical grid.

The state set a record on March 5 when wind turbines generated 6,272 megawatts of energy, or about 19 percent of the electricity on the state’s main power grid.

That peak far exceeded the 6.2 percent average for wind power in Texas, whose 9,410 megawatts of total wind capacity make it the nation’s wind power leader.

But wind power’s growth poses a critical challenge for the state’s booming wind industry, which includes a 180-megawatt wind farm completed last fall near Corpus Christi in South Texas.

On some days wind turbines are slowed or shut down because the state doesn’t have enough transmission wires to send the energy from remote areas, where wind resources are great, to cities that need it, including Dallas and Houston.

The state is planning to spend more than $5 billion to expand and update its transmission system.
