#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. |

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 HIGH confidence The mechanism continuously updates allocations and prices as requests and physical conditions change rather than waiting for a… Show full rationaleHide full rationaleThe 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 rationaleHide full rationaleCoordination is recursive across nested physical layers rather than being performed by one single central optimisation over the entire system. |

Reliability and scarcityDiffers Scarcity allocation | Optimisation-based allocation MEDIUM confidence Operational scarcity is managed through market bids, offers and central system operation decisions subject to security… Show full rationaleHide full rationaleOperational 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 When scarce capacity cannot satisfy all requests, allocation uses persistent fairness state rather than relying only on… Show full rationaleHide full rationaleWhen scarce capacity cannot satisfy all requests, allocation uses persistent fairness state rather than relying only on contemporaneous willingness to pay or a memoryless optimisation. |
