Renewable Energy Portfolio Compliance
The Energy Independence Act, known as Initiative 937, was approved by voters in 2006. It requires state electric utilities serving 25,000 or more customers to obtain at least 15 percent of their electricity from new renewable resources by 2020 and undertake all cost-effective energy conservation.
For energy conservation, I-937 requires each covered utility to identify its achievable, cost-effective conservation potential over a 10-year period, starting in 2010-2011. Utilities must update those assessments at least every two years.
Seattle City Light is meeting or exceeding each of these requirements.
For 2010-2011, City Light's energy conservation target was 172,397 megawatt-hours. City Light achieved 267,813 megawatt-hours of energy savings, exceeding the target by 55 percent.
On the new renewable energy front, City Light has contracts in place to meet I-937's escalating requirements through 2019, measured in terms of renewable energy credits. One credit is created for every megawatt-hour of new, renewable energy produced. In 2020, City Light's target rises to 1,609,000 renewable energy credits. City Light has 836,000 renewable energy credits in place for 2020 and has eight years before that deadline to acquire the rest.
