ACER delivered on EC’s initial request

Ch. 1-2: General provisions, publication

requirements

Ch. 3: Cost allocation and determination of the reference price

Ch. 4-8: Revenue recovery, reserve price, virtual interconnection

points, bundled capacity products, payable price

Avoid risk of

discrimination between

cross-border and domestic

Enable CAM: reserve price,

revenue recovery and payable price

Transparency: methodology,

costs, congestion,

tariff evolution

non-discrimination, effective competition and the efficient functioning of the market cost-reflectivity, avoidance of cross-subsidies, promotion of efficient new investment, and greater transparency

•Prevent cross-subsidies between network users

•Harmonise pricing for interruptible capacity products

Content

•Default proportional pricing for short-term products, but if justified

•Multipliers of 0.5 to 1.5 for Q, M products

•Within 0 and 1.5 for D and W-D products

•Seasonal factors allowed (in combination with multipliers up to 1.5 on average)

• Interruptible pricing shall reflect the likelihood and duration of interruptions

•Backhaul pricing shall reflect the actual marginal (additional) costs

•Bundled capacity products

•priced at the sum of the the reserve prices of the entry and exit points concerned
