Another tariff increase will come into effect as of 1 July 2010.  While tariffs have increased significantly over the past couple of years, as a result of soaring generation costs and unchanged tariffs from 1993 to 2007, Perth Energy can work with you to provide discounts to tariffs and offer fixed prices to help your business beat potential further rises. If your company spends more than $2000 per month on electricity, contact us. “
