What steps is the government taking to reduce barriers to entry for renewable energy providers? Mechanisms that allocate the entirety of the costs of interconnection and network upgrades to the generator (“deep cost allocation”) can be prohibitively costly for investors in clean electricity generation, and therefore constitute a barrier to entry. By contrast, only allocating the costs of the enabling facilities to the generator (“shallow pricing”) will be attractive for developers but can constitute a challenge for the transmission operator (Madrigal and Stoft, 2011).
