Duke Energy says it's expanding its plan to help its customers in need. The utility announced Tuesday it will contribute $700,000 annually over the next five years for low-income energy assistance as part of Duke Energy’s Edwardsport plant regulatory settlement. In addition, Duke Energy Indiana customers and employees have contributed an additional $100,000 in assistance, raising this year’s total to $800,000. Previously Duke customers were eligible for up to $100 in assistance on their energy bill, but under the new plan, those who need help paying their electricity bills can receive up to $300, if their local Energy Assistance Program agency determines they are eligible based on need and other criteria.
