Limit The Financial Impact Of Exporting Surplus Solar Energy To The Public Grid

Curtailment with Pulsen A.I

As the transition to renewable energy accelerates, it brings not only environmental benefits but also new operational challenges. One of the most prominent is ensuring stability across the electricity grid. This shift has led to periods of negative energy pricing—an issue that can substantially impact the profitability of power generation assets. Implementing curtailment strategies has become an effective way to mitigate these risks.

What is curtailment ?

Curtailment refers to the controlled reduction of energy production to keep supply and demand in equilibrium. When solar or wind generation surges beyond what the grid can absorb, the system risks becoming unstable. Such situations frequently trigger negative electricity prices, meaning producers may end up paying to deliver their power. To prevent this, renewable energy operators—like solar parks and wind farms—can intentionally scale back their output, protecting both grid stability and their own financial performance.

Solpulsen is at the forefront of implementing advanced curtailment solutions. With real-time forecasting, we can predict production peaks and dynamically adjust output to avoid overgeneration. To enable this, Solpulsen developed Plusen AI a smart designed to enhance grid stability while improving efficiency for energy producers.

Plusen AI connects directly to a wide range of energy systems, including inverters, battery packs, heat pumps, EV chargers, and energy meters. As an on-site controller, it manages these assets intelligently based on selected control strategies, one of which is curtailment. When negative electricity prices occur and excess power would otherwise be fed into the grid, Plusen AI automatically reduces the solar installation’s output—partially or fully—helping producers minimize financial losses while supporting overall grid stability.

Avoid imbalance market costs.

With access to the imbalance market, curtailment can also be applied beyond standard grid conditions. Operating in this market provides even greater financial advantages, as producers can respond to real-time grid needs and price signals, maximizing returns while contributing to overall system stability.
