Electricity markets as platform markets Weiller, C. Pollitt, M. Working Paper #1334 EPSRC Autonomic Power System Project Presentation at EPRG E&E Seminar 27 th January, 2014
Outline What is a platform market? Why is (retail) electricity becoming one? Cases and examples Consequences for pricing and tariff structures Consequences for energy policy
Examples of platform markets Data storage & cloud computing Dating, recruiting, & social networking websites Online retail, trading platforms, and auctions Operating systems Web search Messaging & Credit cards Entertainment & music News and educational media

What platform markets have in common: Multi-sided markets Network externalities Intermediation service provider Triangular interactions And perhaps... Digital information transmission between user groups Complementary innovation (ecosystem) ICT as the platform technology Service-based business models Enhanced functionality
Theory - Definition One or more user groups linked by a service or product provider that mediates their interactions (Triangular) Network externalities Same-side Cross-side One-way, two-way?... Or none necessary? Difference with a traditional market? Same-side network effects: More than economies of scale Intrinsic value creation primarily by enabling direct interactions
Theory - Definition Source: Hagiu & Wright, 2011 Difference with re-sellers (grocery stores) or input suppliers: Direct interaction Affiliation with the multiple user groups
Theory - Competition Platform competition: Envelopment (Eisenmann et al., 2011) or bundling (Nalebuff, 2004) Competing on the seller-side Competition between users: Compete to sell through the platform (software, video game developers...) Barriers to entry: High switching costs and network effects (Suarez & Kirtley 2012)
Theory – Market structure Single-homing vs. multi-homing Saturation of network effect? Monopoly can be most efficient market structure (Caillaud & Jullien, 2003) Reconfiguration/re allocation of value, rather than Schumpeterian innovation Innovative business ecosystems E.g., Apple Store, Google, Amazon Platform status comes through establishing leadership in a broader business ecosystem (Gawer & Cusumano, 2002)
Theory - Pricing Price structure: Transaction-based vs. fee-based Exclusive services, monopoly or dominant-firm equilibria: Pure transaction Two-sided single-homing: Two-part tariff Multi-homing: Pure registration fee (e.g. Amazon & e-Bay) Valuing network externalities Both sides pay positive prices (e.g. newspapers) One side pays positive prices and the other accesses for free (e.g. some credit cards) One side pays positive prices and the other side pays negative prices, i.e. is compensated for using the platform (e.g. dating websites) Proprietary vs. open platforms
Pricing – User group subsidisation When the network externalities are high enough, i.e. when the marginal cost of connecting an additional user to the platform is lower than the marginal value of its connection for existing and prospective users, the platform provider can apply negative prices to one user group and still collect overall positive profits in equilibrium (Caillaud & Jullien 2003; Economides & Katsamakas 2006). In this case, the most profitable pricing strategy for a platform provider is sometimes to charge below marginal costs for access (Caillaud & Jullien 2003; Economides & Katsamakas 2006; Eisenmann et al. 2011) and for the producers applications (Economides & Katsamakas 2006), simply to attract a wider user base.
A working definition Definition. A platform market is a market where user interactions are mediated by an intermediary, the platform provider, and are subject to network effects. As opposed to a marketplace or trading exchange, a platform intermediary must offer inherent value beyond the simple transaction mediation for the two sides of the market. This added-value usually comes from ICT and the associated complementary innovation that increases utility and attractiveness of the platform to all user groups.
Platforms in electricity?
Drivers of transition in electricity markets 1.Smart metering data: New business models, new entrants Understanding of behaviour Balancing services in retail market 2.Customer participation: Generation owners (solar panels) Storage owners (EVs) Demand-elastic (DSM) Value of consumers as resources 3.Renewables: Volatility, unpredictability (loss of revenue) Value of switchable uptake or VPP 4.ICT: Apps, web interfaces Smart appliances, smart meters New functionality
Emerging realities... Differentiated needs for quality (consumer) Differentiated elasticities of demand (consumer) Differentiated environmental preferences (consumer) Differentiated service preferences (consumer) Differentiated ability to provide services as resources (consumer) Differentiated service offerings (supply) Increased volatility (supply) Availability of more granular data (supply).
Platform positioning Sources: Adapted from Simmonds (2002); UK Department of Energy and Climate Change (2012b); Ofgem (2012) 41 major power producers National Grid Company – Transmission Operator 14 distribution network operators (distribution areas) 15 supply companies Customers Trading through bilateral contracts in forwards, futures and short-term markets (incl. through power exchanges) Wholesale balancing mechanism and imbalance settlement Balancing service platform Electric vehicle management platform Small- and medium-scale power generation (renewables)
Platforms in electricity: Balancing services/Energy optimisation Platform mediator User group 2: Electricity consumers User group 1: Retail suppliers or generators Platform technology: ICT Platform mediator COULD BE: 1.Specialised de novo energy service company 2.ESCO 3.ICT or data management company 4.General service company (finance, retail, etc.)
Platforms in electricity: Electric vehicle charge management Platform mediator User group 2: Electricity consumers User group 1: Retail suppliers or DNOs Platform technology: Charging network* Platform mediator COULD BE: 1.Charging service company 2.Specialised EV aggregator 3.ICT or data management company * The term network refers to the combination of ICT and hardware infrastructure
Why the traditional (current) electricity market is not a platform... Network element, but network externalities? Simple supply chain Electricity is charged to consumers on a transaction basis: per-kWh costs of energy delivered + fixed costs of investments in the network Financial transactions flow linearly from consumers back to generators Two-sided market? ICT/Platform interface is needed to realise value from both sides for both sides The question of subsidising some consumers is not on the table
An electricity platform in practice Multi-homing or single-homing Consumers likely to adopt one platform only Suppliers could participate in multiple platforms, as the value of the optimisation service is to reach as many customers as possible, including those that are not their own customers!, Competitive market structure Co-existence of multiple platforms possible Monopoly (not necessarily inefficient!) Relationship with ESCOs Consumers can use the platform services and remain customers of ESCO Platform could bundle electricity supply + optimisation services, bypassing ESCO Cost/benefits of customer acquisition Target valuable customers first and subsidise their participation Find optimal number of consumer participants
Examples in electricity (Emerging) Functionality: Tracking Billing Advice Remote control Social network Mobile Energy, bill-splitting... Bidgely, consumption monitoring and itemization... Kill-Ur-Watts Simple energy
PHEV manager: The Chevy Volt OnStar
Consequences: Pricing Flat-fee tariff structure, akin to a subscription or registration tariff Consumer differentiation Subsidisation of (consumer-side) user group Consumers as a resource for the system High demand, highly flexible consumers = more valuable Value (monetisation) of service to (supply-side) user group Efficiency, customer service, in DNO revenue calculation Value of certainty of uptake or VPP for renewable generators
Consequences: Society 1.Ethics of smart-metering Does real-time/TOU/peak pricing disproportionally affect lower- income households? (Hogan 2010; Faruqui 2010) A platform-type service could help consumers manage their electricity costs, and ensure an effective re-allocation of value in the market Platform pricing (fee-based) protects the vulnerable Buffer
Consequences 2.Innovation Internalise vs. outsource platform service: New entry Platform market to stimulate complementary innovation and increase consumer interest (e.g. smart phone apps) 3.Social welfare through energy optimisation A platform intermediary that minimises losses and improves the utilisation of the system in the retail sector through a matching service offers a valuable service to both consumers and suppliers Solve peak load problem by making some decisions on behalf of the consumer (constrained by pre-specified preferences)
Conclusions We discussed implications of entry of platform services between consumers and suppliers or DNOs, through cases: Home energy management/balancing services, and EV charging Drivers are consumer differentiation, data availability, and low-carbon transition Future research should investigate the economic aspects of electricity platform pricing Contact:
