| ERCOT is the only centralized market in the US without a capacity market. Generators in ERCOT are expected to earn their revenue via the short term energy and ancillary services markets. ERCOT has been tweaking its market design over the years so that real-time energy prices will spike during times of shortage. Along those lines, in June of 2014 ERCOT implemented its Operating Reserve Demand Curve which is known by its acronym, ORDC. The ORDC creates an adder to the real-time price under certain scarcity conditions. When operating reserves fall below a certain level the ORDC kicks in, increasing the real-time price by increasing amounts as reserves become increasingly scarce. The following figure depicts the ORDC in general terms. Figure 1 | ERCOT Operating Reserve Demand Curve ... » read more | |

| The Northeast just can’t seem to get a break. There have been 3 Nor’easters that landed in the region over the past 3 weeks. While none of the recent storms have matched the bomb cyclone of January, each wintry blast brought massive snowfall and heavy winds to the region that has not been able to shake 'Ole Man Winter'. Figure 1 | Northeast Blocking Pattern Nor’easters develop when arctic winds blow down from Canada. The cold air moves southeast, and storms begin to brew as the winds reach warmer air generally found in high pressure systems over the ocean. This has made New England a prime breeding ground for these storms to develop. Over the course of this year, a blocking pattern has held with a low pressure system sitting over the East Coast and a high pressure ... » read more | |

| Winter weather is not going away any time soon. This is a stark contrast to what the forecasters called for just four weeks weeks ago. By this time we were expected to have broad warming across the West with normal temperatures in the East and Gulf. This was seen as an early beginning to spring and an early end to space heating for many areas of the country. ... » read more | |

| The states of Washington and Oregon just finished their abbreviated legislative sessions. Democrats in both states attempted to pass carbon legislation. At this point in time we can’t be sure whether the legislation simply didn’t have enough support or if it was just too big a lift to manage in an abbreviated session. My sense is that in a full session, which ... » read more | |

| SPP saw a surge of wind throughout the last weekend, serving over 50% of the region's load for nearly the entire time. While there were some curtailments along the way, these were much lower than we would have expected when compared to the fall of 2017. This time around SPP was better able to handle the massive increases in wind. » read more | |

Sometimes it is a joyful transition into spring full flowers and some much needed sunshine. Other years it is a miserable extension of winter that makes you ... » read more | |

| This past week the drought stricken Southern California finally received some rainfall. Many inches of the wet stuff hit Santa Monica, Beverly Hills, and Los Angeles. One of the bi-products of rain in regions with a large installed base of rooftop solar, is increased load during the hours in which the sun would normally shine.
