#1 Fix the energy market

Re-architect how energy is priced, procured, and coordinated across the grid.

Candidate solutions

Compare competing approaches to fixing the energy market against the same design decisions. Each architecture can then be explored, critiqued and developed in detail.

Prices and productsDiffers
Wholesale price geography
National
HIGH confidence

The principal wholesale market operates with a GB wide reference price rather than nodal or zonal wholesale settlement.

Zonal or regional
HIGH confidence

Participants face a common wholesale price within each bidding zone.

Nodal
HIGH confidence

Wholesale prices vary by transmission location.

Zonal or regional
HIGH confidence

Wholesale settlement uses regional reference prices.

Network-hierarchical
HIGH confidence

FP AMM does not assume one fixed national, zonal or nodal geography. Prices can emerge recursively at the relevant network layer.

Show full rationale

Important wholesale markets clear in scheduled batches, while intraday trading continues between auctions and the Balancing Mechanism operates close to delivery. The architecture therefore contains multiple timescales.

Periodic batch clearing
HIGH confidence

Day ahead zonal market coupling is performed through scheduled batch clearing, with additional intraday and balancing processes.

Rolling interval clearing
MEDIUM confidence

The architecture combines scheduled day ahead clearing with repeated short interval real time optimisation.

Rolling interval clearing
HIGH confidence

AEMO performs repeated five minute dispatch and pricing.

Continuous sequential clearing

The mechanism continuously updates allocations and prices as requests and physical conditions change rather than waiting for a…

Show full rationale

The mechanism continuously updates allocations and prices as requests and physical conditions change rather than waiting for a scheduled batch-clearing interval.

Architecture and controlDiffers
Coordination topology
Centralised
HIGH confidence

System balancing and transmission security coordination are principally performed by a central system operator.

Centralised
HIGH confidence

Market coupling and transmission system operation rely on centrally coordinated optimisation and capacity calculation.

Centralised
HIGH confidence

PJM centrally coordinates transmission system dispatch and wholesale market clearing.

Centralised
HIGH confidence

Bulk system dispatch is centrally coordinated by AEMO.

Holarchical
HIGH confidence

Coordination is recursive across nested physical layers rather than being performed by one single central optimisation over the…

Show full rationale

Coordination is recursive across nested physical layers rather than being performed by one single central optimisation over the entire system.

Congestion management

Show full rationale

Transmission constraints that are not represented in the national wholesale price are addressed through balancing, redispatch and constraint-management actions.

Zonal separation + residual redispatch
HIGH confidence

Inter zonal congestion can separate zonal prices while residual intra zonal congestion is managed through redispatch and other…

Show full rationale

Inter-zonal congestion can separate zonal prices while residual intra-zonal congestion is managed through redispatch and other TSO actions.

Congestion embedded in nodal dispatch and prices
HIGH confidence

Binding transmission constraints affect optimal dispatch and the congestion component of nodal LMPs.

Central constrained dispatch + regional settlement
HIGH confidence

Transmission constraints affect central dispatch while wholesale settlement remains based on regional reference prices.

Network-hierarchical coordination
HIGH confidence

Congestion changes the locally relevant scarcity state and therefore the price/allocation signal at the constrained layer.

Reliability and scarcityDiffers
Scarcity allocation

MEDIUM confidence

Operational scarcity is managed through market bids, offers and central system operation decisions subject to security…

Show full rationale

Operational scarcity is managed through market bids, offers and central system-operation decisions subject to security requirements.

Optimisation-based allocation
HIGH confidence

Market coupling determines a welfare maximising feasible allocation from submitted bids subject to cross zonal capacity.

Optimisation-based allocation
HIGH confidence

A security constrained optimisation selects the economically preferred feasible dispatch.

Optimisation-based allocation
HIGH confidence

Central dispatch determines feasible allocation from bids and offers subject to system constraints.

Fairness-aware allocation
HIGH confidence

Show full rationale

When scarce capacity cannot satisfy all requests, allocation uses persistent fairness state rather than relying only on contemporaneous willingness to pay or a memoryless optimisation.

Generator fixed costs can be recovered through energy-market margins, Capacity Market revenues and long-term support contracts such as Contracts for Difference.

Show full rationale

Fixed-cost recovery varies by jurisdiction and can combine energy-market revenues with long-term contracts, support schemes or capacity mechanisms.

Energy-price rentsCapacity payments
HIGH confidence

Resources can recover costs through energy and ancillary service revenues together with PJM's separate capacity market revenues.

Energy-price rentsLong-term contracts
HIGH confidence

Investment returns combine spot market revenues with financial contracts and increasingly long term underwriting arrangements.

System-value payments
HIGH confidence

Show full rationale

Non-fuel fixed costs are separated from the short-run operational energy signal and recovered according to contribution to system value, including the proposed Shapley-based settlement layer.
