Electricity consumption dropping
Energy Consumer use of electricity is dropping due to wider adoption of energy conservation practices. Chugach Electric Association said usage of electricity per residential member has dropped 14 percent since 2004. While weather and the trend toward warmer winters accounts for some of this, the primary driver is energy efficiency.
While this has the effect of reducing natural gas demand, and conserving regional gas supplies, it increases the percentage of renewable energy from hydro and wind in Chugach’s supply portfolio. In 2017 Chugach’s energy supply was 80 percent gas; 16 percent hydro and 4 percent wind. In 2011 the ratio was 92 percent gas and 8 percent hydro (wind did not come into Chugach’s mix until 2012).
