The Law sets up the principle of financial and economic sustainability: the system revenues have to cover all the system costs. Regarding renewable energies, it supersedes the existing special regime for electricity producers, maintaining the fundamental principle of previous supporting schemes: a reasonable return. Remuneration of renewable energies, high-efficiency CHP and waste to energy facilities, will be based on the necessary participation in the market by these facilities, and will supplement the market revenues with a specific regulated subsidy that will enable these technologies to compete on an equal footing with other technologies in the market. This specific subsidy will be sufficient to attain the minimum level required to cover the investment and operating costs that these technologies cannot recover in the market and may enable them to obtain a suitable return.
