Optima's electromagnetic shield
Optima Service is one of the main electricity providers on Hillys. Optima also generates the giant electromagnetic defence shields that protect Hillys' infrastructure from DomZ attacks. They are presumably a wind-power company, as windmills and turbines are the most prominent energy sources on the planet. Service costs 350 Units, though it is unknown upon which time plan this payment is required.
Beyond Good & Evil[]
Optima is the the electricity company used by Jade and Pey'j to power the Lighthouse Shelter and its shield and charge their Hovercraft. During their first DomZ attack, the shield fails because Jade had not paid the service charge which causes a power-cut, and a DomZ meteor breach. Later on, the bill is payed and electricity restored because Secundo introduces Jade to a job with the national Science Center, to pay her for photographs of the local fauna.
