Dead Battery? Wind Power, the Spot Market, and Hydro Power Interaction in the Nordic Electricity Market
Abstract: It is well established within both the economics and power
system engineering literature that hydro power can act as a complement to
large amounts of intermittent energy. In particular hydro power can act as
a "battery" where large amounts of wind power are installed. In this paper
I use simple distributed lag models with data from Denmark and Norway. I
find that increased wind power in Denmark causes increased marginal exports
to Norway and that this effect is larger during periods of net exports when
it is difficult to displace local production. Increased wind power can also
be shown to slightly reduce prices in southern Norway in the short run.
Finally, I estimate that as much as 40 percent of wind power produced in
Denmark is stored in Norwegian hydro power magazines.
