# Locational Marginal Prices (LMPs)

LMPs are the marginal cost of serving one additional MW of load at each bus. In optimization terms, they are the **dual values** (shadow prices) of the nodal power balance constraints.

## LMP Extraction from CVXPY

To extract LMPs, you must:
1. Store references to the balance constraints
2. Solve the problem
3. Read the dual values after solving

```python
import cvxpy as cp
