AES’ Rangeland and High Valley project is a proposed solar + battery energy storage facility to be located in Lancaster and unincorporated Los Angeles County, California.
This project will provide a critical and cost-effective source of clean, reliable power for the region’s electric grid and will also support California’s transition and commitment to achieving 100% carbon-free energy by 2045.
Project overview
110 MW solar + 55 MW battery energy storage
Enough solar energy to power 33,500 California homes and enough storage capacity to power 41,250 California homes for four hours
Lancaster and unincorporated Los Angeles County
Project details
- Located on eight sites totaling 720 acres of privately owned land
- Main project components are solar photovoltaic (PV) module arrays and a battery energy storage system, along with switchgear, communication lines, and generation-tie lines
- AES will be the long-term owner and operator of the facility
Expected project timeline
- Development – Siting – Permitting 2019 – 2025
- Construction 2025 – 2026
- Operations Late 2026
Economic and environmental benefits
We believe in being a good neighbor, ensuring responsible clean energy development that benefits both the environment and local communities without burdening existing infrastructure.
220,374 MWh
Carbon-free electricity generated each year, improving air quality and offsetting equivalent of 156,175 metric tons of CO2 emissions per year
Will provide local economic benefits such as tax revenue for the community and schools over the life of the project
Will provide jobs during construction and operations
Clean energy benefits local communities
- Long-term tax revenue to counties, towns and school districts
- Job creation during construction and operation
- Local economic stimulus during construction
- Affordable, reliable, locally produced clean energy
- Improved air quality and reduced CO2 emissions
- Non-permanent development and low-impact construction that ensures land can be sensitively restored to pre-project conditions at the end of the project’s life
Best practices in responsible and sustainable development
At AES, safety is our highest priority, and we’ve focused on improving lives and building stronger communities for more than 40 years. As a leading innovator in energy solutions, sustainability is core to both our strategy and our culture. We are committed to responsible land use and incorporating sustainable best practices into the entire project lifecycle, contributing to building a domestic circular renewables economy and reducing foreign dependence.
Environmental and technical studies
Because the sites for this project are in the city of Lancaster and Los Angeles County, a joint Environmental Impact Report (EIR) will be prepared. The EIR is a comprehensive analysis that will identify any significant environmental impacts and mitigation measures as required by the California Environmental Quality Act (CEQA). The project will be designed and built in accordance with the latest applicable codes and safety standards.
Partnering with communities for the future of energy
AES is committed to being a good neighbor and partner in the Antelope Valley community. This includes informing and engaging project stakeholders and the public throughout all phases of the project. AES also supports local contractors and has ongoing partnerships with community organizations and programs such as Antelope Valley College.
