KAPASITI SOLAR BOLEH MELANGIT DENGAN PENGANGKUTAN ELEKTRIK DAN PEMANASAN
With wide adoption of electric vehicles and heat pumps, Grid termurah Colorado akan sampai 21 GW kapasiti suria, 12 GW angin, dan 7 GW storan oleh 2040, manakala kadar elektrik akan menurun. Hasil pemodelan ini digunakan untuk negeri lain juga.
Membekalkan kebanyakan pengangkutan dan pemanasan di Colorado akan membolehkan lebih banyak tenaga boleh diperbaharui kos rendah pada grid, sekali gus mengurangkan kos setiap kilowatt-jam untuk semua pengguna di negeri ini, and accelerating achievement of Colorado’s carbon reduction goals.
Solar capacity in Colorado (shown in red above) would soar to about 15 GW by 2030 dan 21 GW by 2040, in an “electrification and decarbonization” scenario modeled by Vibrant Clean Energy, using its WIS:dom energy grid model. Also by 2040, storage with 8 hour duration would reach 7.4 GW (shown in yellow), and wind power would reach 12 GW (shown in green). The study was commissioned by Community Energy.
High levels of solar, wind and storage were facilitated in the model by flexible scheduling of both electric vehicle charging and heat pump operation. Flexible charging for vehicles was constrained to maintain round-trip commuting range, while flexible heat pump operation was constrained to keep building indoor temperatures within 1 degree of 72ºF. The modeling assumed that owners of electric vehicles and heat pumps would participate in flexible scheduling for a compensation of six cents per kWh.
Buildings were also modeled as having backup heating—either supplemental gas or electric heating—because air-source heat pumps lose efficiency on the very coldest days.
