Large Scale Deployment of Renewables for Electricity Generation
Comparisons of resource assessments suggest resource constraints are not an obstacle to the large-scale deployment of renewable energy technologies. Economic analysis identifies barriers to the adoption of renewable energy sources resulting from market structure, competition in an uneven playing field and various non-market place barriers. However, even if these barriers are removed, the problem of ‘technology lock-out’ remains. The key policy response is strategic deployment coupled with increased R&D support to accelerate the pace of improvement through market experience. The paper suggests significant contributions from various technologies, but does not assess their optimal or maximal market share

Market Power and Technological Bias: The Case of Electricity Generation
It is difficult to elminated all market power in electricity markets and it is therefore frequently suggested that some market power should be tolerated: extra revenues contribute to fixed cost recovery,facilitate investment and increase security of supply. This suggestion implicitly assumes all generation technologiesbenefit equally from market power. We assess a mixture of conventional and intermittent generation, eg coal plants and wind power. If all output is sold in the spot market, then intermittent generation benefits less frommarket power than conventional generation. Forward contracts or option contracts reduce the levelof market power but bias against intermittent generators persists

A Comparison of Electricity Market Designs in Networks
In the real world two classes of market designs are implemented to trade electricity in transmission constrained networks. Analytical results show that in two node networks integrated market designs reduce the ability of electricity generators to exercise market power relative to separated market designs. In multi node networks countervailing effects make an analytic analysis difficult. We present a formulation of both market designs as an equilibrium problem with equilibrium constraints. We find that in a realistic network, prices are lower with the integrated market design

Mainstreaming New Renewable Energy Technologies
This paper outlines the benefits, obstacles and options for governments to support international markets for technology
development. International markets for new energy technologies offer greater scope, thereby increasing the incentives and opportunities
for technology improvements. As the market is supported by more independent governments, the confidence of technology developers
and producers that future markets for their products will exist is increasing, thus enabling capital access and inducing R&D investment
and exploration of improved production processes. The bigger markets also allow for international competition, thus allowing for the
application of the best available technology. The government challenge to induce sufficient RD&D remains and with international markets
the benefits and costs of national governments free-riding on international effort needs to be addressed. Finally, we discuss how international
co-operation can be used to evolve the energy system in such a way that it can integrate new technologies at minimum cost

Definition of a Balancing Point for Electricity Transmission Contracts
Electricity transmission contracts allocate scarce resources, allow hedging against locational price differences and provide information to guide investment. Liquidity is increased if all transmission contracts are defined relative to one balancing point, then a set of two contracts can replicate any point to point contract. We propose an algorithm and apply it to the European electricity network to identify a well connected balancing point that exhibits minimal relative cross-price responses and hence reduces market power exercised by generation companies. Market level data which is difficult to obtain or model such as price levels in different regions or that is dependent on the time scale of interaction, as demand elasticity, is not required. The only critical input quantities are assumptions on future transmission constraint patterns
