WP 1 TASK 1.5. MARKET DESIGN AND ACTOR ANALYSIS
LUT tasks:1) Analyses of the feasible energy markets designs in four transformative neo-
carbon scenarios. 2) Identifying the required elements of the market design that enable each
scenario.3) Roadmap; analyzing the possible path and necessary steps from present

Merit order effect for renewables

Impact of RES to market design
Variable marginal cost for production decreases near zeroMerit order for demand-supply equilibrium changes and wholesale prices decreaseCost recovery on new plants unfeasibleInvestment signals are attenuated
Increased volatility of productionIncreased volatility of pricesChanged load profile for non-variable plantDispatchable generation (hydro, biomass, energy storages) can recover high scarcity pricesNeed for balancing mechanisms is increased
Generation relocationNetwork topology changesCongestion issues
Small, scattered energy productionNew market actors; prosumerism
Need to redesign network tariff structuresEtc.

Marginal pricing: zonal ExchangeCapacity mechanisms*,
add-ons**
Marginal pricing: nodal Exchange and/or pool
Capacity mechanisms*, add-ons**
Dispatch based on marginal cost and pricing on LCOE (leveled cost of energy)
Pool No
Pay-as-bid Pool No
Cost of service - No
Over the counter trading (OTC) where market actors decide on pricing
Bilateral No/defined by the state

*Capacity mechanisms are designed to support investment to fill the expected capacity gap and ensure security of supply. E.g. Capacity payments, markets etc. **Add-ons: FiT, FiP, etc.

Framework for determining market designs from transformative scenarios
What are the required elements of the market design that enable each scenario – what kind of market elements are possible in each scenario?Is there a common market for electricity? • Is the system integrated or scattered? Axis for market design
approach 1• Is the price formation open and public or fragmented with bilateral
agreements? Axis for market design approach 2How is the needed generation and transmission capacity obtained?• What are the applied capacity and congestion management
mechanisms? Axis for market design approach 2Which are the driving forces for market development?• Consumer driven vs. corporate driven development Axis for market
design approach 1

Next steps
19.2.2016
1) Deepening the analysis on scenarios’ market designs and options for a 100 % renewable markets in general
2) Analyzing the possible path and necessary steps from present market framework to scenario
3) Agent based simulations of the impacts of market design (continues in 2nd
FP)
Result will be published: “Electricity markets framework in Neo-Carbon Energy 2050 Scenarios” in Neo-Carbon Energy Working Paper series (FFRC e-Book) Conference paper “100 % Renewable Energy System – Challenges and Opportunities for Electricity Market Design. Abstract accepted to EEM 16 (European Energy Markets) conference, which will be held in 6/16 in Porto, Portugal
