The Puerto Rico utility’s favored generation plan, in a report prepared by Siemens, involves an LNG terminal at San Juan and would achieve only 55% renewables by 2038. A scenario without LNG would reach 79% renewables by 2038 at comparable cost, based on undisclosed cost assumptions.
The new governors favor policies such as a higher renewables mandate, community solar, increased use of storage, and expanding the Western grid, reports the nonprofit Advanced Energy Economy.
A new web tool lets consumers in six Southern states see how their utility is embracing solar or blocking it; the tool could help consumers promote improved solar policy.
A solar plant can increase its output by starting from a curtailment status and then reducing curtailment. If grid operators schedule in advance both solar curtailment and increased solar output, the cost-saving level of solar increases substantially.
The platform will be designed to enable tracking and peer-to-peer trading of certificates at the kilowatt-hour scale, at low cost and with improved ease of use.
The island would transition from 2% renewables now to 100% by 2050, in a plan collaboratively developed and endorsed by industry groups and city mayors.
As a further sign that solar is going mainstream across the United States, a new report by Lawrence Berkeley National Labs finds that southeastern states hosted 40% of the utility-scale solar installed nationally in 2017. Interconnection queues have swelled to 188.5 GW of utility solar capacity, eight times more than installed capacity.
With Minnesota’s utilities set to exceed the state’s Renewable Energy Standard, a statewide clean energy association is talking with candidates for governor to promote a higher mandate, to help attract renewables investment and jobs. Similar efforts are underway in eight other states.
