We develop an algorithm called M.I.D.A.S. (Italian Day-Ahead Market Solver) that simulates by iterative splitting the hourly equilibrium (price-quantity) of the Italian day-ahead market taking into account all transmission constraints between zones and the import from neighbouring countries. The algorithm is employed to study the sensitivity of equilibria to changes in production from units employing variable renewable sources, notably sun and wind, at different locations. We show that, when power markets are organised on zonal-basis with locational price signals and final buyers pay a unique price for the power
bought in the day-ahead market, a larger renewable production decreases the average zonal prices, but the distribution of benefits largely depends on power plants’ localisation. We do not limit our analysis to prices, but we study the impact of changes in renewable supply on network congestion, zonal balance
between demand and supply and zonal generation mix. We calculate the zonal substitution effects between renewable and non-renewable technologies, and within renewable technologies as well. M.I.D.A.S. results to be a powerful tool as it sheds some lights on the multiple consequences of energy transition policies and highlights the need of prioritizing over policies’ objectives.
The cattle sector, both emissions- and land-intensive, represents a great opportunity for mitigation through reforestation. In this paper, we study the efficiency of land-use regulation. Our analytical results indicate that the subsidy is the best alternative policy to emissions tax, provided that the elasticities of land use and emissions to cattle feeding are close. Interestingly,...
The workshop aims to identify the key uncertainties and debates regarding the role of bioenergy in a climate neutral economy, at national and global scales, and the challenges for the design of climate policies. Speakers and precise time will be confirmed soon.
