  text: "To provide a simple instrument to operate residential Load-Shifting or Demand-Side-Management
    \r\nsystems, the measurement of the actual grid frequency seems to be an appropriate
    method. Due to the present \r\ninflexibility and the lack of sufficient throttling
    capabilities of lignite and nuclear power plants, a surplus of \r\nelectricity
    generation occurs during periods of high wind and solar power generation. While
    the specific CO2-\r\nemission is decreasing then ‒ due to the increased share
    of Renewables, the grid frequency is increasing (to a certain \r\nlimit). Using
    the grid frequency as an indicator to switch-on and off certain loads (loads that
    do not require power \r\npermanently (e.g. dishwashers, washing machines, dryers,
    fridges and freezers, heaters) could provide a simple, \r\ninexpensive demand-side
    management indicator to lower specific CO2‒emssions and costs (if a dynamic \r\nconsumption
    tariff is available). To check the truthfulness of that hypothesis, the grid and
    frequency data of the \r\nGerman grid of the year 2018 have been collected and
    a the correlation between grid frequency, power surplus, share \r\nof renewables
    vs. CO2-contents and price at the European energy exchange (EEX) have been calculated.
    The results \r\nshow: Correlation between frequency and share of renewables is
    quite low (r = 0.155) due to the fact that primary \r\ngrid control quickly compensates
    deviations from the 50 Hz nominal frequency. There is a good anti-correlation
    (r = -\r\n0.687) between the EEX‒prices and the share of renewables in the grid.
    Over the years, correlation between \r\nelectricity trading prices (EEX) and CO2
    emissions is quite good (r =0.665), within the one year (2018) that \r\ncorrelation
    almost doesn’t exist, possibly due to the inflexibility of the bulky lignite power
    plants that even operate at \r\nnegative prices. \r\n"

  text: 'In order to avoid over-regulation, some countries have experimented with
    what might be called threat-based regulation. The idea is - similarly to the contestable
    market model - that actual regulation may not be necessary as long as the threat
    of regulation is credible. In that case, so the idea, even monopolies will abstain
    from setting monopolistic prices in order to avoid being regulated. As experience
    from Germany and New Zealand has demonstrated, there are quite a number of problems
    associated with threat-based regulatory systems. The most significant problem
    has turned out to be the likely under-regulation and according welfare losses
    from market power, and in this context, a critical issue that has been identified
    is the credibility of the regulatory threat. If the threat of regulation is not
    credible, a light-handed regulatory regime (LHRR) amounts to leaving monopolistic
    firms unregulated, clearly an undesirable situation from a welfare point of view.
    This failure of threat-based regulatory systems results from potential free-rider
    problems associated with good corporate behaviour (as in the case of Germany''s
    electricity market) as well as the lack of credibility of the threat either because
    of the weakness of the enforcement authorities or due to political constraints.
    Furthermore, a problem emerges if exercising the threat of regulation implies
    an abandonment of the LHRR and a corresponding substitution with heavy-handed
    ex ante regulation. An innovative way out of this dilemma has been the quasi-automatic
    threshold system originally designed for New Zealand''s electricity distribution
    networks, which aims at simulating the pressures that companies would face in
    competitive markets. '
