In August, the Massachusetts legislature passed a bill, titled “An Act to Promote Energy Diversity,” that gives the Massachusetts Department of Energy Resources (DOER) the ability to mandate what the energy storage targets.

Electric power stationPower plants in 22 states will be required to further reduce nitrogen oxides (NOx) emissions under a new regulation finalized by the Environmental Protection Agency (EPA) on September 7. The final Cross-State Air Pollution Rule (CSAPR) Update establishes new statewide emissions budgets intended to address pollution that affects the ability of downwind states to meet and maintain the 2008 ozone standard of 75 parts per billion. This is the first time that the EPA has updated an existing program to address interstate transport of air pollution under a new air quality standard. The rule takes effect in May 2017.
