DOE Report on Puerto Rico In June the DOE released the "Energy Resilience Solutions for the Puerto Rico Grid". You can google it and download the pdf. It gives you good insight on where investment dollars need to be spent. Pages 26-29 relate to renewable energy. A couple quotes: " In order to meet legal requirements regarding the transition away from heavy fuel oil, local law requires 20% of sales to be supplied by renewable energy by 2035, indicating approximately 1200 MW of renewable electricity capacity. Using PREPAs pre- and post-storm load forecasts, average daily load will be approximately 2000MW. Thus, by another metric like capacity, the current Renewable Portfolio Standard (RPS) target of sales would translate to an ambitious but still achievable goal." "As part of the 2015 IRP process, PREPA estimated that 322MW of distributed solar will come online through 2035, supplying approximately 17% of the legally required minimum of renewable electricity. This private investment in distributed generation will be facilitated if clear expectations regarding interconnection and remuneration are set and adhered to consistently by all relevant parties." That last line is key..."WILL be facilitated IF CLEAR EXPECTATIONS regarding REMUNERATION are set and adhered to by all". With solar being produced in the USA at 0.05 per kwh in 2016 as the graph in the report shows, and as low as 0.02 per kwh in some areas in 2018, current contracts like Greenbriars that date back to 2013 paying 0.21 kwh are simply no longer realistic. High on the list for investment dollars is changing the existing power plants from burning oil to burning natural gas which will get the cost down to 0.15 kwh. This still leaves P.R. at 90% fossil fuels for power generation so solar is a must especially with its short 2 year lead time until start up. Let's hope Greenbriar can lock down a good contract.
