Sufficient Blackstart Capability Exists on Grid, Say NERC, FERC

May 7, 2018

Despite the recent retirement of “blackstart” units, grid operators have sufficient resources to quickly restore systems in the event of widespread outages, suggests a new report by staff at the Federal Energy Regulatory Commission (FERC) and the North American Electric Reliability Corporation (NERC).

The report—“FERC-NERC-Regional Entity Joint Review of Restoration and Recovery Plans”—released May 2 presents findings from a joint FERC and NERC study that evaluated blackstart resources and planning by nine utilities registered with NERC. NERC—a non-profit international regulatory authority tasked with assuring reliability and security of the grid—defines a blackstart resource as one or more generating units and associated equipment that can be started without support from the bulk power system and is designed to remain energized without connection to the system. A blackstart unit energizes other equipment. The first generating unit in its cranking path is known as a “next-start” generating unit.

According to the report, blackstart generating units included in the participants’ system restoration strategies—and most participants had more than one, it noted—ranged from small (50 MVA) to larger units (100–200 MVA), to banks of generating units exceeding 1,000 MVA in capacity.…

MHPS Tops GE, Siemens in Gas Turbine Market

A report from Barclays Plc said Mitsubishi Hitachi Power Systems (MHPS) received more than half of all global orders for gas-fueled turbines in the first quarter of 2018, the company’s best-ever performance in a market that has seen traditional gas turbine manufacturers struggle in recent months.

The market report from the London, UK-based multinational investment bank was released May 3. It said Germany-based Siemens AG had 26% of global orders in 1Q2018, with Boston, Mass.-based General Electric (GE)—long the leader in worldwide turbine sales—seeing its share drop to 14%. GE CEO John Flannery, who took the reins of the company last year and immediately set out to restructure its operations, has said GE was slow in recognizing slowing demand for gas-fueled turbines. Flannery has changed the leadership of the company’s struggling Power division and said the group needs a “right-sizing” for market structure, including changes to portfolio, supply chain, and supply base by 2020.

Flannery’s outline for changes came at almost the same time in November 2017 as Siemens announced it would consolidate its power divisions and cut 6,900 jobs.…

DOE Steps Up Investments into Electric Generation Technology Research

The U.S. Department of Energy (DOE) over the past two weeks has made a string of funding announcements, including nearly a half-billion dollars of new investment in power-related initiatives. The funding backs advancements in cybersecurity, advanced nuclear, solar, bioenergy, fuel cells, geothermal, and energy storage.

$ 25 Million for Cybersecurity.On April 16, the DOE’s Office of Electricity Delivery and Energy Reliability’s Cybersecurity for Energy Delivery Systems program issued a $ 25 million funding opportunity announcement (FOA),seeking applications to conduct research, development, and demonstration (RD&D) for innovative approaches to advance cyber-resilient energy delivery systems.

The project hones in on five areas: redesign of cyber-resilient architecture for the power and oil and natural gas (ONG) subsectors; cybersecurity for the ONG environment; cybersecure communications; cybersecure cloud-based technologies in the operation technology environment; and innovative technologies that enhance cybersecurity in the energy sector. Applications are due by June 18, 2018.

$ 105 Million for Solar Technology. On April 17, the DOE’s Solar Energy Technologies Office said it would fund about 70 projects to advance both solar PV and concentrating solar thermal power (CSP) technologies and help them secure facilitated integration into the grid.…

PJM Says Grid Reliable, but Will Analyze Resilience

The operator of the nation’s largest electrical grid on April 30 reiterated its system will remain reliable even with the retirements of substantial generation resources. But PJM Interconnection, whose system covers customers in 13 states, said it will conduct a review of its operations over the next several months “to understand the fuel-supply risks in an environment trending towards greater reliance on natural gas.”

PJM wants to know whether its network could still operate reliably in the event of outages from natural disasters such as extreme weather, a cyberattack, or pipeline issues that would curtail the flow of natural gas on its system. The regional transmission organization (RTO) in March 2017 issued a report—”PJM’s Evolving Resource Mix and System Reliability”—that said its system could add more natural gas and renewable power generation and remain reliable, but “heavy reliance on one resource type” could bring risks to grid resiliency.

PJM recently said more than 3,600 MW of generation capacity will retire in its service territory in 2018.…

Net Metering and Time-Variant Rates Drive Solar Power and Energy Storage Growth [PODCAST]

April 29, 2018

Nevada law has included net metering provisions for more than 20 years. Net metering is an arrangement that allows energy generated by a customer’s leased or purchased solar system to offset monthly power bills. It also permits excess energy supplied to the grid to earn credits, which are then automatically applied to future billing periods in which more energy is consumed than produced.

Historically, net metering was a one-for-one transaction in Nevada. For every kWh supplied to the grid, a credit was given to the customer for one kWh in the future. The scheme changed in 2015 when the Nevada Public Utilities Commission (PUC) created a laddered approach that ratcheted down the value of customer-generated energy over a period of years to about 2¢/kWh, which was much less than the retail rate of about 11¢/kWh. The change effectively stopped all construction on new residential rooftop solar systems.

Through Assembly Bill 405 (AB 405), the Nevada Legislature modified the net metering rate structure effective June 15, 2017.…

EPA Rampaging on Coal Ash Rule Despite Groundwater Concerns

Despite pleas by environmental groups for more time to review recent dumps of groundwater monitoring data from power companies, the Environmental Protection Agency (EPA) is forging ahead to finalize a proposed overhaul of the Obama administration’s 2015 final Coal Combustion Residuals (CCR) rule.

The EPA’s 45-day comment period for the agency’s March 1 proposed rule, which includes more than a dozen significant changes to the 2015 action, is slated to end on April 30. Most of the rule’s changes focus on providing more regulatory flexibility to owners of coal ash landfills or surface impoundments, and they explicitly give states the authority to operate CCR permit programs “in lieu of federal regulations,” as long as they are agency-approved. According to the EPA, those changes are expected to save industry between $ 32 million and $ 100 million per year.

However, the proposal also seeks to address four provisions that a federal court remanded to the agency in June 2016. Those changes, for example, propose a clarification of the type and magnitude of non-groundwater releases that would require a coal plant to comply with corrective action procedure, and it adds boron to a list of constituents that may trigger corrective action.…
