As the example shows, in some cases peak shaving makes sense to avoid peak loads and to keep grid usage costs low.
When it comes to managing peak loads, there are a few different approaches. 'Peak load monitors' track and regulate a pre-defined peak load every quarter of an hour. If the monitor predicts that the accumulated peak load will exceed a certain threshold in the next quarter-hour interval, certain power consumption processes are reduced. This allows a company to determine and influence its maximum power consumption.
If reducing load is not desired or possible, a company can provide its own supplemental power to avoid peak loads. Additional power could come from sources such as the company’s own electricity storage facilities or CHP plants. This creates a time-limited provision of power from the electricity storage facilities and/or a generator within the company’s grid, which absorbs the additional peak load at the transfer station before it reaches the public grid.
For distribution network operators, peak shaving is a good way to keep the costs of network expansion low. An efficiently-operating network requires less copper installation in the form of power lines and distribution points. Uniform power generation and consumption is the ideal scenario, leading grid operators to create an incentive for reducing peak loads, especially in light of increasingly volatile feed-in from wind and photovoltaics.
