A framework to identify marginal electricity production technologies for consequential life cycle assessment: A case study of the electricity sector • A novel framework was developed to identify long-term marginal energy suppliers.
• 9 scenarios were formulated to assess the effects of policy decisions on the energy system.
• Wind energy generation shows significant penetration in all scenarios.
• Renewable energy penetration could lower the grid emissions up to 74.6 kg CO2 eq/MWh.
• Combined cycle and wind are the long-term marginal suppliers in Alberta’s grid transition. University of Alberta | Publication | 2021-07-15 | Tanveer Mehedi, Eskinder Gemechu, Matthew Davis, Kumar, A. |
Developing a framework to assess the long-term adoption of renewable energy technologies in the electric power sector: the effects of carbon price and economic incentivesLarge-scale deployment of renewable energy can play an immense role in transforming the global energy system and mitigating emissions. This paper describes the development of a novel framework called MArket Penetration ModeLing of Renewable Energy Technologies in Electric Power Sector (MAPLET-PS). MAPLET-PS assesses the impacts of policy measures such as carbon price and financial incentives on the adoption of renewable energy technologies. The framework was used to develop a case study for the electric power sector ofAlberta, a fossil-dominated province in Western Canada. The results show that implementing a carbon price on
fossil fuel electric power sources and incentives for renewable energy, along with the phase-out of coal-firedelectricity generation, can mitigate 29% of Alberta’s electricity sector 2020 GHG emissions by 2050 and reduce GHG emissions from 46.5 Mt of CO2 eq. in 2020 to 23.6 and 29.1 Mt of CO2 eq. per year in 2030 and2050, respectively, in Alberta. Moreover, these changes can increase the share of renewable energies from 12.5% in 2018 to 30% in 2050. These rates can be achieved by implementing a carbon price along with a 1000 $ incentive per kW new capacity development and 70 $ incentive per MWh electric power generation from renewable sources, from 2021 to 2025, primarily from wind turbines.
