Traditional analysis of distribution grid user's reaction to tariffs assumes a low price sensitivity and a lack of alternative technologies to grid connection. This is radically changing with two technology breakthroughs: (1) Photovoltaics (PV) enable domestic and commercial consumers to...

Capacity mechanisms have been controversial in theory as well as practice. Lessons from experience with different capacity mechanisms led to the development of the reliability options. This mechanism promises two advantages over other types of capacity mechanisms. Firstly, it ensures the...

In many countries, distribution grid tariffs are being reformed to adapt to the new realities of an electricity system with distributed energy resources. In Europe, legislative proposals have been made to harmonize these reforms across country borders. Many stakeholders have argued that...

The EU network codes and guidelines are a detailed set of rules pushing for the harmonisation of national electricity markets and regulations. The areas for the development of network codes and guidelines were set out in the Third Energy Package. By the end of 2017, a total of eight network...

Demand-side flexibility can be incentivised to reduce the need for investment in distribution grids either implicitly or explicitly. Implicit demand-side flexibility is when prosumers react to price signals triggered by network tariffs. Explicit demand-side flexibility is when the DSO can...

Electricity markets with high installed capacities of Variable Renewable Energy Sources (VRES) experience periods of supply and demand mismatch, resulting in near-zero and even negative prices, or energy spilling due to surplus. The participation of emerging Power-to-X solutions in a sector...

Flexibility markets are recognised as a promising tool to make better use of existing distribution grids and thereby also reduce the need for grid investments. In this paper, we analyse four pioneering projects implementing flexibility markets: Piclo Flex, Enera, GOPACS and NODES. Based on a...

There is a trend in regulatory practice towards exceptional incentives for exceptional investments. Italy and the US have the longest experience with a regulatory framework for strategically important investments that deviates from the default framework. In these countries, the incentives...
