| One point absorber design tested at commercial scale by [[CorPower Ocean|CorPower]] features a negative spring that improves performance and protects the buoy in very large waves. It also has an internal pneumatic cylinder that keeps the buoy at a fixed distance from the seabed regardless of the state of the tide. Under normal operating conditions, the buoy bobs up and down at double the wave amplitude by adjusting the phase of its movements. It rises with a slight delay from the wave, which allows it to extract more energy. The firm claimed a 300% increase (600 kW) in power generation compared to a buoy without phase adjustments in tests completed in 2024.<ref>{{Cite web |last=Blain |first=Loz |date=2024-03-07 |title=Video: Wave-amplifying generator bounces twice as high as the swells |url=https://newatlas.com/energy/corpower-wavespring/ |access-date=2024-04-12 |website=New Atlas |language=en-US}}</ref> | One point absorber design tested at commercial scale by [[CorPower Ocean|CorPower]] features a negative spring that improves performance and protects the buoy in very large waves.

| A wave farm (wave power farm or wave energy park) is a group of colocated wave energy devices. The devices interact hydrodynamically and electrically, according to the number of machines, spacing and layout, wave climate, coastal and benthic geometry, and control strategies. The design process is a multi-[[optimization problem]] seeking high power production, low costs and limited power fluctuations.<ref>{{Cite journal|last1=Giassi|first1=Marianna|last2=Göteman|first2=Malin|date=April 2018|title=Layout design of wave energy parks by a genetic algorithm|journal=Ocean Engineering|volume=154|pages=252–261|doi=10.1016/j.oceaneng.2018.01.096|s2cid=96429721 |issn=0029-8018|url=http://urn.kb.se/resolve?urn=urn:nbn:se:uu:diva-346695}}</ref> Nearshore wave farms have substantial impact on beach dynamics.
