Uhlelo lokulawula ukuziqalela lulawula ngokuzenzakalelayo ukusebenza/ukuma kwesethi ye-generator, futhi futhi inomsebenzi wezandla; Esimeni sokulinda, isistimu yokulawula ithola ngokuzenzakalelayo isimo se-mains, iqala ngokuzenzakalelayo ukukhiqiza amandla lapho igridi yamandla ilahlekelwa amandla, futhi iphuma ngokuzenzakalelayo futhi ime lapho igridi yamandla ithola amandla kagesi. Yonke le nqubo iqala ngokulahleka kwamandla kusuka kugridi kuya kugesi kusuka ku-generator ingaphansi kwamasekhondi angu-12, okuqinisekisa ukuqhubeka kokusetshenziswa kwamandla.
Isistimu yokulawula ikhethiwe i-Benini (BE), i-Comay (MRS), i-deep sea (DSE) namanye amamojula okulawula ahamba phambili emhlabeni.
