In the US, Tucson Electric Power (TEP) filed its smart grid infrastructure upgrade and development plan with the Arizona Corporation Commission (ACC).In a press statement, TEP said its 2017 Integrated Resource Plan (IRP) includes the company’s current resource portfolio and strategies to help the utility meet its energy demand over the next 15 years.
David G. Hutchens, CEO of TEP, said: “We’re evolving from a traditional utility to a more technology- and consumer-focused provider of energy products and services while maintaining reliability, convenience and affordability for our customers.”
TEP is planning to improve its energy mix by expanding its portfolio of renewable energy resources including solar and wind to 30% of its total energy capacity by 2030. The utility said it will add up to 800MW of renewable energy capacity by 2030.
The Arizona-based energy company plans to increase its investments in gas-fired energy generation to reduce its reliance on coal-fired energy generation and achieve grid reliability during times when renewable energy generation fluctuates.
The utility plans to increase its deployment of energy efficiency and demand response programmes to sustain the reliability of its network during peak periods and reduce energy bills for its customers.
The energy plan will increase TEP's energy storage portfolio by adding up to 100MW of storage capacity. Recently, TEP completed three energy storage projects with a total capacity of 22MW.
The successful implementation of TEP's 2017 energy plan will allow the utility to retire up to 508MW of coal-fired energy generation by 2022.
Meanwhile, the city of Wapato in the US state of Washington has announced its plans to use $300,000 grant received from the Washington state department last year to reduce its energy bills by deploying energy efficiency measures.
The city said it will implement an energy efficiency project which includes installation of some energy efficient appliances in eight buildings owned by the city.
The city is replacing existing air conditioners, lights, thermostats and gas furnaces with energy efficient models.
The project is expected to energy bills in city-owned buildings by 50%.
Mario Guzman, the mayor of Wapato city, said: "It costs a little over $18,000 a month for the lighting in the City of Wapato, which included the street lights,,. I mean it will cut that down to under 9,000 a month."
