Market Value

Market value_key figure

Energy Economics. The market value of wind power declines with its market share. We explain why and by how much. The quantification is based on empirical market data, a quantitative meta-analysis of published studies, and modeling in EMMA. At a market share of 30%, each MWh of wind-powered electricity is worth 40% less than at a small market share.

Optimal Share

Optimal share_key figure

The Energy Journal. We estimate the cost-optimal market share of wind and solar power, explicitly taking into account their output variability, finding 20%, three times more than today. Variability significantly impacts results: if winds were constant, the optimal share would be 60%. We present and explain several surprising findings, including a negative impact of CO2 prices on optimal wind deployment.

Redistribution_key figure

Energy Policy. Supporting renewables adds additional power suppliers to the market, depressing the price. Consumers benefit, while incumbent generators lose. We quantify this effect with EMMA and compare it to the (converse) effect of carbon pricing.

Balancing Power

Balancing_key figure

Renewable & Sustainable Energy Reviews. Balancing power is used to quickly restore the supply-demand balance in power systems. The need for this tends to be increased by the use of wind and solar power. Empirical evidence, however, tells another story: while German wind and solar capacity has tripled since 2008, balancing reserves have been reduced by 15% – and costs by 50%!
