From 2010 to 2012, grid intervention events increased fourfold in Germany. Similarly, <a href=\"http:\/\/www.nature.com\/news\/renewable-power-germany-s-energy-gamble-1.12755\">Nature Publishing Group<\/a> claims,<\/p>\n<p>&#8220;The rapid rise in wind and solar power has created a nightmare scenario for grid operators, who face surges when the wind blows and the sun shines, and shortages when they don\u2019t.\u00a0 In 2011, more than 200,000 blackouts exceeding three minutes were reported \u2013 and experts warn of a growing risk of major power failures.\u201d<\/p>\n<p>But this criticism is shortsighted. SAIDI specifically measures blackouts exceeding three minutes, and since 2006 Germany\u2019s solar and wind capacity have increased by 70 GW while its SAIDI has improved from 21.53 to 15.32.\u00a0 Furthermore, as argued by Craig Morris for the <a href=\"http:\/\/energytransition.de\/2014\/08\/german-grid-more-stable-in-2013\/\">Heinrich B\u00f6ll Foundation\u2019s <i>Energy Transition<\/i> blog<\/a>, all \u2018grid intervention\u2019 events mean is that \u201cinstead of merely sitting there looking at screens, the engineers now have to press buttons\u201d; as a result, there is a \u201c<i>slightly<\/i>\u201d higher likelihood of human error.<\/p>\n<p><b>The most valid concern<\/b><\/p>\n<p>Of all the criticisms against Energiewende\u2019s reliability success, the issue of cost is the most valid. As it turns out, upgrading the electric grid to a state-of-the-art, 21<sup>st<\/sup> century machine is pretty expensive, and that cost is mostly borne by utilities.<\/p>\n<p>Too rapid an increase in generation from renewables is financially weakening German utilities, which make only a fraction of the revenue dispatching renewable power as from conventional sources. The value of Europe\u2019s top 20 utilities has fallen from \u20ac1 trillion (USD $1.3 trillion) in 2008 to \u20ac500 billion (USD $630 billion) in 2013. <a href=\"http:\/\/www.economist.com\/news\/briefing\/21587782-europes-electricity-providers-face-existential-threat-how-lose-half-trillion-euros\">According to The Economist<\/a>, European grid upgrades by 2020 are expected to cost up to \u20ac1 trillion, and \u201ccompanies worth \u20ac500 billion cannot finance anything like that amount\u2026 In their current state, utilities cannot finance Europe\u2019s hoped-for clean energy system.\u201d<\/p>\n<p>Thus, crippling these utilities is potentially problematic for reliability because it lowers the potential for investment in the modernized grid. This concern, however, has yet to erode Germany\u2019s electric grid reliability in practice.[Tweet &#8220;Data supports conclusion Germany\u2019s grid reliability during Energiewende has been an unequivocal success so far http:\/\/ow.ly\/D35o2 &#8220;]<\/p>\n<p><b>Solutions exist<\/b><\/p>\n<p><a href=\"http:\/\/sallan.org\/pdf-docs\/Germany_CapacityEnergyMarkets.pdf\">According to the Heinrich B\u00f6ll Foundation<\/a>, \u201ceven the strongest proponents of Energiewende agree that Germany needs to reform its energy system to accommodate the next influx of renewable energies.\u201d<\/p>\n<p>However, solutions exist to this problem that are not revolutionary. For example, a shift away from the \u201cenergy-only\u201d market, in which utilities are <i>only<\/i> paid to produce and deliver energy, to one that is more profitable for utilities as renewables take over the generation mix. Potential structures include \u201ccapacity\u201d and \u201ccapabilities\u201d markets.<\/p>\n<p>In a capacity market, utilities are not compensated for the energy they produce, but instead for what they have on reserve for immediate use when faced with reliability challenges. But this model does not give preference to any particular energy source. A capabilities market, however, attempts to prioritize power generation that guarantees low CO2 emissions. Natural gas-fired plants, energy storage, <a href=\"https:\/\/blogs.edf.org\/energyexchange\/2014\/04\/21\/demand-response-people-not-new-power-plants-are-driving-the-clean-energy-future\/\">demand response<\/a>, and renewable energy resources are just a few examples of the reliability measures that might be prioritized over a coal-fired \u201cpeaker\u201d plant when trying to meet the demands of a strained electric grid.<\/p>\n<p>The highest quality data supports the conclusion Germany\u2019s grid reliability during Energiewende has been an unequivocal success so far.
