Fitch Ratings has given Taiwan Power's NT$13.3 billion senior unsecured bonds an AAA(twn) national long-term rating, according to a recent release.

The proposed bonds' rating is equivalent to the company's national long-term rating as they serve as its direct, unconditional, unsecured and unsubordinated obligations.

The company's rating is similar to that of Taiwan, stemming from an extremely strong potential of government support.

The similar ratings also reflect the company's leading position in Taiwan's power market and its strategic role for energy security.

The company's rating is at the highest end of Fitch's national rating scale, given its status as one of Taiwan's top issuers and implying a low default risk compared to other Taiwanese issuers.
