The US electricity grid is one of the most complex engineered systems in the world, serving over 330 million people and countless businesses. Behind the scenes, a sophisticated regulatory framework ensures this critical infrastructure operates reliably, affordably, and sustainably. For energy professionals, understanding this regulatory landscape—and having access to the right documents—isn't just helpful. It's essential.
01 The Regulatory Structure
Key Insight: US electricity regulation operates on a dual federal-state system, creating a complex web of overlapping jurisdictions and regulatory requirements.
Federal vs. State Jurisdiction
The regulatory landscape is fundamentally shaped by the Federal Power Act of 1935, which established a crucial distinction:
Federal Regulation (FERC)
- Interstate transmission of electricity
- Wholesale electricity sales
- Interstate natural gas pipelines
- Hydroelectric licensing
- Reliability standards enforcement
State Regulation (PUCs)
- Retail electricity rates
- Local distribution systems
- Resource planning and procurement
- Utility franchises and service territories
- Renewable energy standards
This division creates a regulatory environment where a single electricity transaction can touch multiple jurisdictions. A renewable energy project, for example, might face:
- FERC oversight for interconnection to the transmission grid
- State PUC approval for power purchase agreements
- ISO/RTO market participation requirements
- NERC reliability standards compliance
- EPA environmental regulations
- Local zoning and permitting requirements
02 Key Players and Their Roles
FERC
Federal Energy Regulatory Commission
The primary federal regulator overseeing interstate electricity transmission and wholesale markets. FERC ensures just and reasonable rates, approves major transmission projects, and enforces market rules.
ISOs/RTOs
Grid Operators
Seven regional grid operators manage electricity markets and ensure grid reliability across two-thirds of the US. They operate wholesale markets, manage transmission, and coordinate system operations.
NERC
North American Electric Reliability Corporation
The electric reliability organization responsible for developing and enforcing reliability standards. NERC oversees the bulk power system across North America.
State PUCs
Public Utility Commissions
State regulators overseeing retail electricity markets, distribution utilities, and local resource planning. Each state has unique rules, processes, and priorities.
Important Context
Unlike many countries with centralized energy regulation, the US system reflects its federal structure. This creates opportunities for state-level innovation (like California's renewable energy leadership) but also challenges for interstate projects and market coordination.
03 How Electricity Markets Work
Understanding electricity markets is crucial because market design fundamentally shapes how the grid operates and how regulatory decisions impact stakeholders.
The Two-Settlement System
Day-Ahead Market
Generators submit supply offers and load entities submit demand bids for the next day. The ISO clears the market, establishing schedules and prices for each hour.
- Runs approximately 36 hours before delivery
- Provides financial certainty and scheduling
- Optimizes system-wide efficiency
Real-Time Market
As actual conditions deviate from day-ahead schedules, the real-time market balances supply and demand every 5 minutes.
- Handles forecast errors and unexpected outages
- Sets real-time prices (LMPs)
- Ensures instantaneous grid balance
Settlement
Market participants are settled based on differences between their day-ahead schedules and real-time performance.
- Day-ahead settlements provide baseline revenue
- Real-time deviations result in additional charges/payments
- Complex settlement calculations account for losses, congestion, and reserves
Locational Marginal Pricing (LMP)
Most US wholesale markets use LMP, which sets prices at thousands of locations across the grid. LMPs reflect:
- Energy component: Marginal cost of generation
- Congestion component: Cost of transmission constraints
- Loss component: Cost of electrical losses during transmission
Why this matters: LMPs can vary dramatically across a region—from $20/MWh in low-demand areas to $1,000+/MWh during constraints. Understanding LMP patterns is crucial for siting generation, evaluating transmission investments, and managing market risk.
Capacity Markets
Several ISOs operate capacity markets to ensure long-term resource adequacy:
| ISO/RTO | Market Type | Commitment Period | Key Feature |
|---|---|---|---|
| PJM | Capacity auction | 3 years forward | Variable Resource Requirement (VRR) curve |
| ISO-NE | Forward Capacity Market | 3 years forward | Sloped demand curve |
| NYISO | Installed Capacity Market | 6 months forward | Locational capacity zones |
| CAISO | Resource Adequacy | 1 month to 1 year | Bilateral contracting |
04 The Regulatory Process
Regulatory proceedings follow established processes, but understanding the nuances is critical for effective participation.
FERC Proceedings
Filing or Notice
Utility, ISO, or other entity files proposal (rate change, tariff amendment, etc.)
Public Comment
21-day comment period; interventions and protests filed
Staff Analysis
FERC staff reviews, may request additional information
Commission Decision
Order issued approving, modifying, or rejecting proposal
Rehearing/Appeal
Parties may seek rehearing or appeal to federal court
ISO Stakeholder Processes
ISOs operate extensive stakeholder processes to develop and modify market rules. These processes are:
- Consensus-based: Typically require sector-weighted voting (generators, load, transmission, etc.)
- Iterative: Proposals go through multiple committee and board reviews
- Transparent: Extensive documentation of proposals, comments, and decisions
- Time-consuming: Major changes can take 1-2 years from concept to FERC approval
Case Study: PJM Capacity Market Reform
In 2018, PJM proposed changes to its capacity market to address state subsidies. The process included:
- 18+ months of stakeholder discussions
- Multiple competing proposals
- Hundreds of pages of analysis and comments
- Board approval in 2019
- FERC rejection and remand
- Additional stakeholder process and re-filing
- Final FERC approval in 2020
Total time: Nearly 3 years. Documents generated: Thousands of pages across filings, comments, testimony, and orders.

- Recent changes: Track ongoing market design changes affecting renewables → Active dockets with dozens of filings and comments
Scenario 2: Load-Serving Entity
A utility must procure capacity for its 5,000 MW load obligation. They need to:
- Understand requirements: Review resource adequacy rules and planning parameters → Tariff sections, manual updates, and seasonal filings
- Evaluate options: Compare capacity market participation vs. bilateral contracts → Historical auction results, price formation analysis, and expert testimony
- Assess risk: Understand penalty structures and compliance requirements → FERC enforcement orders, tariff penalty provisions, and compliance manuals
- Monitor changes: Track proposed rule changes affecting procurement strategy → Active stakeholder processes with weekly updates
The Cost of Information Gaps
Time Waste
Energy professionals spend 20-40% of their time searching for and reviewing regulatory documents across multiple sources.
Missed Opportunities
Critical filings, deadlines, or market opportunities are missed because relevant information is scattered or difficult to find.
Financial Risk
Decisions based on incomplete information can lead to multi-million dollar mistakes in project development or procurement.
Compliance Risk
Overlooking tariff requirements or regulatory changes can result in violations, penalties, or legal disputes.
