Amends Constitution to prohibit construction of new fossil fuel power plants.

SCR 18 proposes a constitutional amendment banning new fossil fuel power plants (burning coal, natural gas, oil, or petroleum) for electricity generation in New Jersey. It would not apply to repairs of existing plants or to "peaking power plants" operating at low capacity (10% or less) during peak demand periods to stabilize the grid. The amendment defines key terms like "base load" (minimum daily electricity needs) and "peak demand" to clarify exemptions. This policy change requires voter approval to take effect and would directly affect developers planning new fossil fuel facilities.
