Renewable portfolio history: In 1999, Texas Public Utilities Commission adopted rules for a renewable electricity mandate. The 1999 standard called for 2,000 megawatts (MW) of new renewables to be installed in Texas by 2009, in addition to the 880 MW of existing renewables generation at the time.[iii] Wind accounts for nearly all of the current renewable-energy generation in Texas and 4.9% of total electricity generation. Accepts out of state supply (but limited) and engages in credit trading but does not accept existing capacity. In 2004, the Texas Renewable Portfolio Bill (SB No. 20) included a requirement that the state must meet 500 MW of the 2025 target with non-wind renewable generation. Texas law now mandates at least 500 MW from renewables other than wind[iv]
Credit Trading: Yes
Noncompliance penalty: An administrative penalty of $50 per MWh renewable generation shortfall.[v]
Electricity Price Ranking: 17th Highest[vi]
- 9.65 cents/KWh in Texas
- 7.67 cents/KWh in non-mandated states
