Wind, healthy gas, and solar done adult roughly all new electric era ability in 2015, accounting for 41%, 30%, and 26% of sum additions, respectively, according to rough data. The information also uncover a record volume of distributed solar photovoltaic (PV) ability was combined on rooftops via a nation in 2015. The trend of wind, healthy gas, and solar additions creation adult many new ability is expected to continue in 2016.
Wind. Wind installations usually increasing in 2014 and 2015 from reduction than 1,000 megawatts (MW) combined in 2013. Uncertainty surrounding a extensions and modifications of a sovereign prolongation taxation credit (PTC) over a past several years led to vast fluctuations in annual breeze additions. The record volume of additions in 2012 was followed by a steep drop-off in 2013 and a successive miscarry in 2014 and 2015—a settlement also manifest with prior years’ PTC death and renovation cycles.
Texas combined a many breeze ability (42% of sum breeze additions), followed by Oklahoma, Kansas, Iowa, and North Dakota. All of these states are located in a executive partial of a country, where breeze resources are a strongest. In Texas, new breeze appetite annals are invariably being set as a breeze swift continues to grow.
Natural gas. Natural gas additions, especially combined-cycle plants, were reduce in 2015 than in new years. New Jersey and Texas together done adult half of all healthy gas additions.
In New Jersey, many of a new ability came from dual combined-cycle plants, a Newark Energy Center (685 MW) and a Woodbridge Energy Center (795 MW). Both plants will be granted by a Transco healthy gas pipeline, that recently finished expansions to move incomparable volumes of Marcellus healthy gas to marketplace areas.
In Texas, a second proviso of a combined-cycle Panda Temple Power Station (734 MW) and 3 explosion turbine plants totaling 716 MW (Ector County Energy Center, Montana Power Station, and Elk Station) came online.
Utility-scale solar. California combined some-more than 1,000 MW any of utility-scale and distributed solar PV capacity, accounting for 42% of altogether solar additions in 2015. North Carolina combined 720 MW of utility-scale PV, some-more than double a volume combined in a state in a prior year. In Nevada, a 110 MW Crescent Dunes concentrating solar thermal plant with appetite storage came online in 2015 along with several solar PV plants totaling 236 MW.
Distributed solar PV. Distributed PV saw poignant expansion in 2015, quite in a residential sector, where sum commissioned ability rose most faster over a year than in a industrial or blurb sectors. While still distant behind tip distributed solar PV states, several states saw important expansion in 2015, including Nevada, where distributed PV ability some-more than doubled from 49 MW to 129 MW. Further expansion of Nevada’s distributed PV sector, however, is capricious since Nevada’s Public Utility Commission recently authorized several changes to a net-metering tariffs, including phasing in reduce net-metering remuneration rates and aloft monthly bound charges for distributed PV customers. These changes are an bid to residence concerns about grid upkeep costs being shifted disproportionately from business with solar systems to non-solar customers.
