AES — Energy Portfolio Analysis

Key Finding: AES operates a substantial and geographically diverse power generation portfolio in the US, heavily weighted towards natural gas and solar, with a notable concentration of capacity in California and Indiana.

Geographic Concentration and Diversity

AES maintains a presence across 14 US states, demonstrating a broad operational footprint, though significant capacity is concentrated in a few key regions.

• California (CA): 18 plants totaling 5.7 GW, representing the highest plant count and capacity concentration for AES.
• Indiana (IN): 7 plants totaling 3.9 GW, indicating a strategic focus with fewer, larger facilities.
• New York (NY): 8 plants totaling 812 MW, showcasing a dispersed set of assets within the state.
• Virginia (VA): 6 plants totaling 831 MW.
• Hawaii (HI): 5 plants totaling 308 MW, reflecting a smaller, potentially niche market presence.
• Michigan (MI): 2 plants totaling 40 MW, indicating a minimal footprint in the state.
• Louisiana (LA), Mississippi (MS), and Texas (TX): Each with 1 plant, suggesting highly localized or single-asset operations in these states.

Fuel Mix and Capacity Dominance

AES's US portfolio of 13.1 GW is primarily composed of natural gas and solar assets, reflecting a dual strategy encompassing both conventional and renewable generation.

1. Natural Gas: Accounts for the largest share of capacity with 8 plants totaling 4.8 GW.
2. Solar: Represents the highest number of facilities with 24 plants totaling 2.3 GW.
3. Battery Storage: Comprises **8

Key Finding: Recent news signals indicate AES is actively advancing solar and battery storage projects while navigating environmental challenges associated with legacy fossil fuel assets.

Commitment Signals: Accelerated Renewable Deployment

Recent announcements highlight AES's strategic focus on renewable energy development, particularly in solar and battery storage, demonstrating clear execution on their clean energy commitments.

• Solar Farm COD: The energization of a 250-MW solar farm with 180-MWh BESS by AES Indiana and a new desert solar project feeding Las Vegas casinos indicate successful project completion and grid integration.
• California Solar-Storage: The finalization of the first phase of a large solar-storage plant in California further underscores progress in hybrid project deployment.

Constraint Signals: Navigating Environmental and Permitting Hurdles

Despite renewable advancements, AES faces notable challenges related to environmental legacy issues and emerging regulatory constraints in specific regions.

• Moratorium on Storage: Van Zandt Commissioners' moratorium on lithium storage poses a potential impediment to future battery energy storage system (BESS) development in that locality.
• Coal Ash Contamination: AES Indiana is addressing public and regulatory scrutiny regarding coal ash contamination corrective measures at Harding Street Station, indicating ongoing environmental remediation efforts.
• Elevated Arsenic Concerns: Continued reporting on "decades of pollution and elevated arsenic" associated with coal ash ponds suggests persistent environmental liabilities requiring attention and investment.

These signals collectively portray an entity aggressively pursuing growth in renewables, particularly solar and storage, but simultaneously managing environmental legacy issues and emerging regulatory resistance in specific areas.

AES's development pipeline is exclusively focused on battery storage and solar-plus-storage projects, with a significant concentration of large-scale projects in Texas.

AES's Queue Pipeline Dominated by Storage in Texas

• AES has 5 projects in its interconnection queue, all of which are currently active.

• The total capacity across these 5 projects is 1,354 MW.

• A substantial 967 MW across 3 projects are dedicated solely to Battery storage technology.

• Another 387 MW across 2 projects are Solar+Battery hybrid developments.

Largest Queue Projects Concentrated in Texas

• The largest project, Beacon Storage (TX), is a 408.7 MW Battery storage facility.

• Following closely is Sigma Storage (TX), another Battery project with 408.4 MW.

• The Caesar Storage (TX) project contributes 205.5 MW as part of a Solar+Battery hybrid.

• The associated Caesar Solar (TX) project adds 181.6 MW.

• A single project in New Mexico accounts for 150 MW of Battery storage, named null (NM).
