Powell’s family had long been associated with county politics: his great-uncle Thomas Powell had represented the boroughs in 1725 and Cardiganshire in the Parliament of 1741, and both his grandfather and his father pulled their weight in elections, the latter allying himself in 1788 and 1796 with Edward Loveden Loveden of Gogerddan against Lord Lisburne.
Powell also obtained the lord lieutenancy. At his election he was reminded by one of the senior gentry, Gwynne of Monachty, that he had yet to prove his worth and he sought to gain approval. In February 1817 he chaired the county meeting for a petition against the sea coal duties and earned thanks for his part in securing their reduction in September.
