ABQ's Charge: How Far to the Next EV Station? Custom Case Solution & Analysis

1. Evidence Brief (Case Researcher)

ABQ (Albuquerque Municipal Transit) revenue model relies on municipal subsidies (Exhibit 1).
Operating cost per mile for electric buses: $0.85; diesel: $1.42 (Exhibit 2).
Charging infrastructure capital expenditure: $150,000 per depot-based charger; $450,000 per en-route fast charger (Exhibit 3).
Annual maintenance budget: $4.2M, with 15% inflation projected for EV-specific parts (Para 12).

Fleet size: 120 buses; 25% currently electric; 75% diesel (Para 4).
Average route length: 18 miles; round trip time: 120 minutes (Exhibit 4).
Grid capacity at main depot: 4.5 MW, currently utilized at 85% (Para 15).
Technical constraint: Current battery degradation rate is 8% per year in high-heat conditions (Para 18).

City Council: Demands 100% fleet electrification by 2030 (Para 2).
Union Leadership: Expresses concern over technician retraining requirements and safety protocols for high-voltage systems (Para 22).
Fleet Manager: Prefers phased replacement to avoid stranded assets (Para 25).

Total cost of ownership (TCO) comparison over a 12-year vehicle lifespan is missing.
Projected electricity rate volatility is not provided.
Specific geographic constraints for en-route charger installation permits are absent.

How can ABQ meet the 2030 electrification mandate while maintaining service reliability and fiscal solvency?

Value Chain Analysis: The bottleneck is not vehicle procurement but the energy distribution and charging infrastructure. The current depot-centric model creates a single point of failure.
Resource-Based View: The workforce lacks the skill set for electric powertrain maintenance, creating an operational dependency on external vendors.

Option 1: Accelerated Depot-Based Charging. Focus capital on expanding depot capacity. Trade-offs: Lower upfront costs; higher operational risk due to range anxiety and deadhead miles.
Option 2: Hybrid Infrastructure Strategy. Mix of depot charging and selective en-route fast chargers at high-traffic hubs. Trade-offs: Higher capital intensity; improved operational flexibility and lower battery stress.
Option 3: Phased Outsourcing. Outsource fleet maintenance and charging management. Trade-offs: Shifts risk to third parties; reduces long-term control over service standards.

Option 2 is the preferred path. It provides the necessary range buffer to ensure reliability while spreading capital expenditure over the remaining transition period.

Month 1-3: Grid assessment and utility partnership negotiation for en-route charging sites.
Month 4-9: Technician certification program launch; procurement of long-lead electrical hardware.
Month 10-18: Pilot installation of two en-route chargers; data collection on battery performance.

Grid Capacity: The existing 4.5 MW limit is near capacity. Any major expansion requires utility-scale upgrades.
Labor Readiness: The current maintenance team cannot service the new fleet, creating a potential service backlog.

Contingency: Maintain a 10% reserve fleet of diesel buses until the en-route charging reliability is proven over 12 months.
Workforce: Implement a tiered incentive program for mechanics who obtain EV certification.

ABQ must pivot from a procurement-led strategy to an infrastructure-led strategy. The current focus on vehicle counts ignores the latent grid constraints and maintenance skill gaps that will trigger a service collapse by 2027. The city should immediately pause fleet acquisition to reallocate $5M toward grid upgrades and workforce training. Without this shift, the 2030 mandate is a political goal that will fail operationally.

The assumption that grid capacity can be managed through smart charging at the depot. The case ignores the utility provider’s ability to guarantee power availability during peak summer months.

Operational Fragility: High heat (Albuquerque climate) accelerates battery degradation beyond manufacturers' optimistic projections. Probability: High. Consequence: Premature fleet replacement costs.
Union Resistance: The transition risks a labor strike if retraining is not treated as a primary, funded workstream. Probability: Moderate. Consequence: Total service stoppage.

Microgrid Investment: Decentralized solar-plus-storage at key transit hubs. This avoids grid dependency and mitigates demand charges during peak hours.
